Comparing the effects of face-to-face and on-demand lectures on grades and class evaluations
Full text link新型コロナウイルスの流行により，多くの大学でオンライン授業が導入され，非対面型の講義が一時的に主流となったが，現在，対面授業への移行が促されている。本研究は，対面授業とオンデマンド授業（非同期型）の学習効果を比較し，成績，授業評価，授業中の感情状態から多角的に検討することを目的とした。信州大学の学生96名を対象に，対面授業とオンデマンド授業をそれぞれ受講させ，授業後アンケートと小テストを実施した。結果，試験成績に有意な差は見られなかったが，授業評価では対面授業が高く評価された。これらの結果から，対面授業の学習効果とオンデマンド授業の改善点について議論した。The COVID-19 pandemic led many universities to adopt online classes，making lectures without face-to-face interaction the standard. Recently，governments are encouraging a return to in-person classes. This study compares the learning outcomes of face-to-face and on-demand (asynchronous) classes by evaluating grades，class evaluations，and emotional responses. The experiment was conducted in social psychology lectures at University. Participants attended one face-to-face class and one on-demand class. After each lecture，they completed a questionnaire and，after a certain period，took a short test. The results showed no significant difference in test scores between the two conditions. However，the face-to-face classes were evaluated more favorably than the on-demand classes. These findings provide insights into how to improve on-demand classes，offering new contributions to educational research.departmental bulletin pape

障害のある子どもの学校の在り方について
Full text link小中学校の通常学級には知的障害を伴わない発達障害の子どもが約8.8%在籍していると言われる。この子どもたちは学習や行動に著しい困難が生じており、学校に適応できていない可能性がある子どもたちである。本稿では、明治期の実践記録も紹介しながら、現代の特別支援教育が一人も取りこぼさない教育を進め、共生社会の形成を目指すシステムであることを確認し、その上で障害のある子どもたちの学校の在り方を考える上での基本的な事柄や課題を示したい。なお、この講演録は、令和7年2月1日に松本市勤労福祉会館で開催された、令和6年度松本市特別支援教育フォーラム「障がいのある子どもの学校の在り方」において事前に準備した口述原稿をもとに構成した。departmental bulletin pape
Two Cases of Laparoscopic Removal of Peritoneal Dialysis Catheter Obstruction due to Fallopian Tube Intrusion
Full text linkA potential complication of peritoneal dialysis (PD) is obstruction of the PD catheter. Although relatively rare, this obstruction can occur due to the fimbria of the fallopian tube. Herein, we report two cases in which PD catheter obstruction caused by invagination of the fimbria of the fallopian tube was treated laparoscopically. The patients were 88 (Case 1) and 67 years old (Case 2). PD was initiated for chronic renal failure. The PD catheter was inserted into the abdominal cavity at two finger widths below the umbilicus, with the tip placed in the Douglas pouch and the catheter exit point created in the left immediate abdomen. The PD catheter became obstructed 1 month after insertion in Case 1, and 1 year and 8 months in Case 2. A contrast medium was injected into the PD catheter under fluoroscopy. In Case 1, omental entanglement was suspected, whereas in Case 2, mesentery or adnexal obstruction was suspected. In both cases, attempts were made to relieve the obstruction using a guidewire ; however, this proved challenging. Therefore, the abdominal cavity was observed laparoscopically. In both cases, the right fimbria was invaginated through the side hole of the PD catheter, necessitating its removal, and resection of the fallopian tube or fimbria. Postoperatively, PD was resumed without any problems with infusion or drainage. Gynecologists should be aware that when blockage occurs due to the fimbria, removing the catheter carries a high risk of recurrence. Measures to prevent recurrence should be considered.journal articl
Regional Differences in ‘Ninen-mairi’ in Nagano Prefecture Municipal Histories: Folklore Restructuring and Dialectal Variation
Full text link大晦日から元日にかけての社寺詣を指す「ニネンマイリ」という新語の誕生は、明治から昭和中期にかけてだと推測される。なぜならこの概念が成立するには「1月1日午前0時」をもって新年が始まるという時間意識がなければならず、そうした意識は明治5（1872）年の暦制改革以後に成立をみたからである。本論では、1970年から2000年にかけて刊行された長野県市町村誌の記述を資料に用いた。まず、大晦日から元日に行われる社寺詣の民俗的な実態を調査すると５タイプに分かれる。そのうち、大晦日深夜から年をまたいで参詣し、元日には社寺詣を行わない地域が、松本平と長野市周辺に分布していた。また、厄払などの付加価値をもつ特定社寺へは大晦日深夜から年をまたいで参詣し、地元の社寺へは元日早朝に詣るという二種類を行う地域が、上小地域（現在の上田市、東御市、長和町、青木村）と諏訪地域（諏訪氏、岡谷市）を中心にみられた。こうした民俗的実態をふまえると、「ニネンマイリ」は、大晦日深夜の厄払と、元日早朝の二つの参詣を区別するこれらの地域のどこかでまず誕生したと推測される。1970年までには、大晦日深夜の参詣しか行わない松本、長野地域へも伝播して分布域を広げたと考えられる。他方、経済と交通の発達にともない、娯楽や観光目的で行う大晦日深夜の参詣様態が長野県を含め全国的に発生した。長野県ではこれも「ニネンマイリ」と呼んだものが外行し、全国に広がったと考察した。The author estimates that the new term ‘ninen-mairi’, which refers to pilgrimages to shrines and temples from New Year's Eve to New Year's Day, was born between the Meiji and mid-Showa periods. The reason for this is that in order for this concept to be established, there had to be a sense of time that the New Year began at midnight on 1 January, and such a sense of time was established after the calendar reform of 1872. In this paper, descriptions in Nagano Prefecture Municipal Magazines published between 1970 and 2000 are used as sources. First, a survey of the folkloric reality of shrine and temple pilgrimages held from New Year's Eve to New Year's Day reveals five types. Of these, the areas where pilgrimages are made from midnight on New Year's Eve across the year and no shrine and temple pilgrimages are made on New Year's Day are distributed in Matsumoto area and Nagano City. There were also areas that two types of pilgrimages are made, mainly in the Johsho area (present-day, Ueda City, Tomi City, Nagawa Town and Aoki Village) and Suwa area (Suwa City and Okaya City), where midnight pilgrimages are made to specific shrines or temples, sometimes with added value, such as for the exorcism of bad luck and nearby shrine and temple pilgrimages are made on New Year’s Day. The author estimate that the new dialect ninen-mairi’ was born in these area. By 1970, it is thought to have spread to the Matsumoto and Nagano regions, where only midnight New Year's Eve pilgrimages are made, and to have expanded its area of distribution. On the other hand, with the development of the economy and transport, a form of midnight New Year's Eve pilgrimage for the purpose of entertainment and sightseeing emerged throughout the country, including Nagano Prefecture. In Nagano Prefecture, this is also called ‘ninen-mairi’, and which spread throughout the country.journal articl
Trends of the Patients Hospitalized for Severe Hypoglycemia in Type 2 Diabetes
Full text linkAim : Severe hypoglycemia remains a major complication of diabetes ; however, the background of patients with severe hypoglycemia requiring hospitalization has not been unraveled. Therefore, in this study, we examined the characteristics of patients who required hospitalization for severe hypoglycemia. Methods : We included 330 patients with severe hypoglycemia who had type 2 diabetes and who visited the Aizawa Hospital Emergency and Critical Care Center during a 12-year period. Furthermore, we divided the patients into two groups : patients treated with insulin (INS-group) and those treated with oral hypoglycemic agents without insulin (OHA-group). We examined the time of hospital visits and the proportion of patients requiring hospitalization. Results : The proportion of patients requiring hospitalization was significantly lower in the INS-group than in the OHA-group. The proportion of patients who visited the hospital because of severe hypoglycemia between 12 : 00 and 17 : 59 was significantly higher in the INS-group than in the OHA-group. There was no significant difference in the proportion of patients who were hospitalized and those who could return home across all periods in the INS-group. The proportion of hospitalized patients was low between 0 : 00 and 5 : 59 and high between 18 : 00 and 23 : 59 in the OHA-group. Conclusions : In insulin-treated patients, there is a risk of severe hypoglycemia, even with poor glycemic control. However, patients treated with OHA alone were at increased risk of hospitalization for severe hypoglycemia in cases of excessively good control and the visit time between 18 : 00 and 23 : 59.These findings suggest strategies that can reduce the risk of severe hypoglycemia and hospitalization.journal articl
