Social exclusion is an important social problem, especially for people with disabilities. Empirical knowledge on what explains social exclusion in this population will be essential to understand how disability is socially constructed through the formation of social barriers. The purpose of the current study is to empirically examine the effects of mobility on perceived social exclusion among people with disabilities. The authors reviewed theoretical perspectives in order to develop a hypothesis postulating the relationship between mobility and perceived social exclusion among people with disabilities. Then, to empirically test the study hypothesis, the authors examined the survey data and geo-location tracking data from people with physical impairments. Our analysis of the survey data revealed that two mobility variables (the frequency of going-out and the level of discomfort when going out) were significantly associated with perceived social exclusion. Our analysis of geo-location tracking data revealed that travel patterns were significantly associated with perceived social exclusion among people with physical impairments. Implications were discussed.��� ��������� 2018������ ������(���������������������������)��� ������������ ��������������������� ��������� ������ ��������� ��������� (No. 2018R1A5A7059549
Deubiquitinating enzymes as cancer biomarkers: new therapeutic opportunities?
Cancer remains a life-threatening disease and accounts for the major mortality rates worldwide. The practice of using biomarkers for early detection, staging, and customized therapy may increase cancer patients' survival. Deubiquitinating enzymes (DUBs) are a family of proteases that remove ubiquitin tags from proteins of interest undergoing proteasomal degradation. DUBs play several functional roles other than deubiquitination. One of the important roles of DUBs is regulation of tumor progression. Several reports have suggested that the DUB family members were highly-elevated in various cancer cells and tissues in different stages of cancer. These findings suggest that the DUBs could be used as drug targets in cancer therapeutics. In this review, we recapitulate the role of the DUB family members, including ubiquitin-specific protease, otubain protease, and important candidates from other family members. Our aim was to better understand the connection between DUB expression profiles and cancers to allow researchers to design inhibitors or gene therapies to improve diagnosis and prognosis of cancers.This research was supported by the Basic Science Research Program through the National Research Foundation of Korea (NRF), which is funded by the Ministry of Education (2017R 1A2B2008727, 2018M3A9H3022412 and 2017M3A9B3061830) and Bio and Medical Technology Development Program of the National Research Foundation (NRF) and funded by the Korean government (MSIP and MOHW) (2017M3A9E4048172)
Impact of Lean Manufacturing Practices on Firms’ Sustainable Performance: Lean Culture as a Moderator
Nowadays, manufacturing firms are pressured by governments, non-governmental organizations and customers to operate in a sustainable manner. Although lean practices may provide environmental, social, and financial benefits to firms, their effect on sustainable performance is ambiguous. The aim of this study is to examine the effect of lean manufacturing practices on firms’ environmental performance by considering lean culture as a moderator. Data were gathered through a survey of 187 manufacturing firms in Malaysia and were analyzed using the partial least squares technique. The results indicate that process and equipment, product design, supplier relationships, and customer relationships have a positive and significant effect on sustainable performance. It is also interesting to observe that lean culture positively moderated the effects of process and equipment and supplier relationships on sustainable performance. These results have important implications for enhancing the sustainable performance of manufacturing firms through lean manufacturing practices
Impact of hydrate saturation on water permeability in hydrate-bearing sediments
Permeability of the hydrate-bearing sediments critically affects the hydrate dissociation process as well as the rate and efficiency of gas production. Reported permeability values are observed to be widely are very scattered owing to the dependence on multiple factors such as experimental conditions and test procedures. It is critical that the permeability is measured accurately to enable prediction of long-term gas production using numerical simulation for an economic development of hydrate-bearing reservoirs. In this study, the tetrahydrofuran (THF) hydrates that exhibit pore habits of the pore-filling pattern are formed in sediments, and the water permeability is quantified as a function of hydrate saturation. The results show that a decrease in the permeability for an increase in the hydrate saturation. Based on the measured values that are bounded by Kozeny grain-coating and pore-filling models, the fitting parameters of the empirical permeability models are suggested for use in numerical simulation of long-term hydrate dissociation. Wave velocity measurements reveal pore habits of pore-filling pattern of THF hydrates in the sediments with S-h �� 0.5, and a gradual transition to patchy and load-bearing pore-habits when S-h �� 0.6. The numerical simulation results obtained using the complementary pore-network model suggest that the THF hydrates in the sediments may form in small clusters with an average patch size of similar to 4 pores.This work was supported by the research fund of the Korea Agency for Infrastructure Technology Advancement (18CTAP-C142849-01) and the National Energy Technology Laboratory (NETL) of US DOE.

A wedding dress design that applies the traditional dang-ui
The aim of this study is to develop new wedding dress designs by blending the traditional female Korean upper garment of Han-bok, known as dang-ui, with Western-style wedding dress designs. For this research, the author considered the various types of wedding dresses and their historical development based on literary resources and previous studies of the subject. The results are as follows: first, this study featured the use of different types of fabric for the dang-ui, selected from the various fabrics available for wedding dresses. Starting from the basic design of a sleeveless and strapless princess-line tight top, three different styles of A-line dresses were created: a tiered long dress, an unbalanced tiered midi dress, and a spangled and pleated mini dress. The study also resulted in a tight H-line mini dress with a bustle. In this way, the author was able to suggest new wedding dress styles that are well suited to the cultural trend of the Korean wave. Second, the traditional Korean dang-ui is an elegant ceremonial garment that harmonizes well with Western-style wedding dresses. Satisfaction can be found from combining these creative fusion gowns with traditional Korean aesthetics. Third, the traditional Korean ceremonial coronet jokduri and veil, which go well with dang-ui wedding dresses, are suitable accessories for contemporary wedding dresses. The dang-ui wedding dress, a result of merging the Korean dang-ui and the Western style, will help enhance business for both the Korean and the international wedding industry thanks to an aesthetic that has global appeal

The purpose of this paper is to clarify the phonetic characteristics of the anger utterance during the utterance of the male and female speakers in their twenties who have Korean as the mother language. In this paper, 20 female and 20 male and female residents of Seoul and Gyeonggi provinces were interviewed. Then, quantitative analysis which normalized the utterance and statistical analysis and qualitative analysis which examines the pattern of the representative utterance and the strong word pattern were carried out. As a result, the ratio of the female accent to the male accent was smaller than that of the male accent. In the group, the lower syllable pattern and the lower horizontal group appeared in the ‘low’ syllable, and the highest pitch was observed in the female group. However, in the case of a woman, the number of herringbone was lowered. In the judgment questionnaire, the slope of the whole sentence was higher than that of the male, and showed a large pitch shift. The slope of the male and female pairs was larger than that of male, and the ratio of male and female pairs was short. In addition, the pattern of female and male tongue was different from that of female. In the explanatory questionnaire, the slope of the total sentence of the woman was higher than that of the male, showing a large pitch shift. However, unlike the previous study, in which the explanatory questionnaire was mainly emphasized on the slope of the bilateral amphibian, it showed a rise in the case of women and a lower emphasis on the case of men. The first syllable of the female showed high horizontal group which is different from that of the traditional group pattern.��� ��������� 2018��� ������������ ������������ ��������������������� ��������� ������ ��������� ���������(NRF-2018 S1A5A2A03036312)
A comparative study of energy and carbon efficiency for emerging countries using panel stochastic frontier analysis
The demand for energy has been increasing significantly worldwide. Consequently, carbon emissions have accelerated, since energy usage involves carbon dioxide. Given that the available energy has quantitative restriction feature, efficient usage of energy becomes crucial. Energy efficiency is expected to improve over time with technological advancements. However, the adoption of low-carbon energy technology caused by the growing concern about carbon emissions may actually offset energy efficiency, owing to the higher cost compared with traditional energy methods. We conducted a stochastic frontier analysis to examine energy efficiency in the views of both economic and ecological aspect view during 1995-2016 for 21 emerging countries selected from Morgan Stanley Capital International, using energy consumption, economic complexity index and the other factors of production based on the Cobb-Douglas production function. Mexico was identified as one of the most energy-efficient countries; however, Mexico could not be classified as real energy efficient, as it demonstrated the highest carbon inefficiency level. We also categorized countries demonstrating increased economic energy efficiency and decreased carbon inefficiency as frontier country, and identified six such countries.This work was supported by the Human Resources Development program (No. 20194010201860) of the Korea Institute of Energy Technology Evaluation and Planning (KETEP) grant funded by the Korea government Ministry of Trade, Industry and Energy
(CONSORT) Wound closure using Dermabond after excision of hemangioma on the lip
Background: As the lip contains ample blood supply, hemangiomas often occur in this area. When surgical excision is performed, wound closure is important. To prevent infection from saliva and food, watertight wound closure is needed. The purpose of this study is to demonstrate the usefulness of Dermabond for wound closure after hemangioma excision on the lip.
Methods: Between December 2015 and August 2017, 11 patients with lip hemangioma underwent surgical excision. When closing the wound, Dermabond was used for skin closure after subcutaneous sutures. Demographic data and complications were recorded. Scars were evaluated with the Vancouver scar scale (VSS), and the postoperative shape of the lip was assessed on a 10-point satisfaction scale at 1 month and 6 months postoperatively.
Results: All cases completely healed without any complications, such as wound dehiscence or infection. There were no recurrences at postoperative 1 month during the follow-up period. The aesthetic results of the scars were also excellent. The average VSS score on postoperative 1 month was 4.2, and it decreased to 2.2 at postoperative 6 months. The average patient satisfaction score at postoperative 1 month was 7.4, and it increased to 9.5 at postoperative 6 months.
Conclusion: Dermabond is useful for wound closure after hemangioma excision on the lip. It prevents wound contamination, and yields acceptable aesthetic results

Weight change and mortality and cardiovascular outcomes in patients with new-onset diabetes mellitus: a nationwide cohort study
Background Because weight control is a cornerstone of diabetes management, it is important to understand the relationship of weight change to risk of cardiovascular disease (CVD) among patients with type 2 diabetes mellitus (DM). We aimed to investigate whether changes in weight early after diagnosis influence the incidence of CVD and all-cause mortality in patients with type 2 DM.MethodsUsing nationally representative data from the Korean National Health Insurance System, 173,246 subjects with new-onset DM who underwent health examinations during 2007-2012 were included. Weight was measured at the time of diabetes diagnosis and 2years later. Weight change over 2years was divided into five categories of 5% weight change, from weight loss -10% to weight gain 10%.ResultsThere were 3113 deaths (1.8%), 2060 cases of stroke (1.2%), and 1767 myocardial infarctions (MIs) (1.0%) during a median follow-up of 5.5years. Subjects with weight gain 10% had a significantly higher risk of stroke (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.23-1.84), compared with the group with stable weight. There was no significant association between weight change after diagnosis of DM and incident MI. All-cause mortality showed a U-shaped curve according to weight change. The group with weight loss -10% had the highest HR for all-cause mortality (HR 1.86; 95% CI 1.61-2.14) and the HR for weight gain 10% was 1.61 (95% CI 1.37-1.89).ConclusionsWeight changes of more than 10% after diabetes diagnosis were associated with higher mortality and over 10% weight gain was associated with increased risk of stroke.This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (2018R1D1A1B07049079).
