The emerging legal framework for private sector development in Viet Nam's transitional economy
No full textA major objective of Viet Nam's transition to a market economy has been to reactivate the private sector in a mixed economy. Several new laws have been introduced in the past five years to implement this policy and to create an enabling environment for the private sector. The author reviews some of the more important laws and regulations that affect Viet Nam's private sector activities, including laws on real property, intellectual property, companies, domestic investment, foreign investment, bankruptcy, contracts, and dispute resolution. Anti-monopoly law has not yet been introduced in Viet Nam. The issue of competition is addressed in the context of trade law, the relative roles of the state and private sector, and restrictions in company law. These areas all establish the foundation of a legal framework for a market economy. The author concludes that Viet Nam's legal framework, like China's, is still influenced by ideology, which causes problems in such areas as private ownership of real property and with such fundamental legal concepts as"due process of law."It is noted that the private sector is constrained by the lack of an independent judiciary, the absence of private land ownership, other uncertainties in property law that limit the develpoment of financial markets, and the inherent bias of the system in favor of the state sector (and collective ownership). Also noted is a law-abiding attitude, equally important to development has been slow to develop. The author goes on to point out that the foreign investment process is too complicated, and its company law too restrictive. A first priority should be to strreamline regulations, as well as liberalize trade policy and increase efforts in privatization of state enterprises. In this respect the author notes that export processing zones may be a useful interim instrument to attract foreign investment but should be phased out over time. More important in the long term is a good investment climate resting on a strong legal foundation.Legal Products,Environmental Economics&Policies,Banks&Banking Reform,Municipal Housing and Land,Municipal Financial Management,Environmental Economics&Policies,Banks&Banking Reform,Municipal Housing and Land,Legal Products,Municipal Financial Management

Study design for the 2016 baseline survey of a health system strengthening project in Quoc Oai District, Hanoi, Vietnam
No full textBackground: In order to provide essential scientific evidence on the population's health status and social health determinants as well as the current capacity of the health care system in Vietnam to health policy makers and managers, Vietnam Ministry of Health, Hanoi University of Public Health, Hanoi Medical University, and Ho Chi Minh University of Medicine and Pharmacy collaborated with Seoul National University (Korea) and conducted a health system survey in the Quoc Oai district (of Hanoi capital) that represented northern rural Vietnam. Methods: The study design was a cross-sectional study. The survey covered different topics (more than 200 questions) and was administered in three separate questionnaires: 1) Basic information of all household members; 2) Household characteristics; and 3) Individual characteristics. Socio-demographic characteristics among the households and individuals were collected from 2,400 households sampled by multi-stage cluster sampling method: more than 200 questions. Results: The household size of Quoc Oai was larger than the national average and there was no significant difference in gender composition. In addition, the proportions of pre-elderly, age 55-64, and elderly group (65 years old and over) were higher than the national population statistics. In this context, demographic transition has begun in Quoc Oai. Conclusion: This study design description provides the basic information about a baseline survey of a future prospective cohort (as a part of a collaborative project on strengthening the health system in Vietnam) to the prospective data user of this survey. © 2019 The Korean Academy of Medical Sciences. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Huy Nguyen” is provided in this record*

(2001: 51) in variant shape of leaves, triangular ovate spathe limb and general florescence structure but differs from the latter in having plain green (vs. variegated) leaves, underground (vs. above ground) flowering spathe tube, abaxially reddish purple to greenish grey, brownish mottled and ascending (vs. dark green flushed with dirty brown and horizontal) spathe limb, erect (vs. ascending) spadix, bright yellow staminodes curved downwards at their tips only (vs. pale yellow staminodes curved upwards or downwards over their entire length), ovoid (vs. spathulate to pyriform) fruits and generally smaller floral parts (3.5–4.5 vs. 8.0– 13.5 cm long spadix, 3.5–5.0 × 2.0–2.5 vs. 7–14 × 4.0– 7.5 cm spathe limb, 2.0–3.5 × 0.4–0.5 vs. 4.5–9.0 × 0.6–1.0 cm spadix appendix). Type:— VIETNAM. Ba Ria - Vung Tau Province: Binh Chau - Phuoc Buu Nature Reserve, about 107 o 30’52’’E, 10 o 36’17’’N, 30 m elevation, 05 August 2015, Le Van Son, Nguyen Phi Nga & Van Hong Thien H . T. Van 115 (holotype SGN!, isotypes PHH!, VNMN!). Herb seasonally dormant; rhizome tuberous, subglobose to ellipsoid, underground, 1.0– 1.5 cm long, ca. 1 cm in diameter, producing many thick roots. Leaves 4–5. Petiole smooth, slender, 7–15 cm long, 2–3 mm in diameter, white to grey with brownish mottled at base, green towards the apex. Leaf blades entire or pedatisect, green above, pale green beneath; entire blades linear, deltoid to lanceolate, 6–10 cm long, 2–8 cm wide, with acuminate to obtuse apex; pedatisect blades with 3 to 5 linear to lanceolate segments (up to 15 cm long, 2.0– 4.5 cm wide). Inflorescence, solitary (rarely 2), slightly foetid smelling; peduncle underground, elongated in fruiting, white, 1.5–2.0 cm long, ca. 3–5 mm in diameter; spathe 4.5–6.0 cm long; spathe tube underground, separated from the limb by a constriction, ovoid or ellipsoid, 1.3–1.7 cm long, 9–10 mm wide, outside white with brownish dots, inside white to pale pink; spathe limb triangular ovate, 3.5–5.0 cm long, 2.0– 2.5 cm wide, outside reddish purple to greenish grey, brownish mottled, inside dark purple to reddish purple; spadix little shorter than spathe, sessile, erect; female zone conical, 2–3 mm high, ca. 5 mm in diameter at base, with 6–7 rows of crowded pistils; ovary obovoid or slightly cylindrical, 1 mm high, 0.7 mm in diameter, translucent white with brownish dots at apex, 1-locular, with 1 basal ovule; style very short; stigma disciform, thick, 0.6 mm in diameter, 0.3 mm high, blackish purple to pink, papillate; sterile zone contiguously female zone, 8–10 mm long, lower part covered with 3–4 rows of staminodes, upper part naked; staminodes bright yellow, subulate, 2–3 mm long, ca. 0.5 mm in diameter, ascending forming an obtuse angle with the spadix axis, slightly curved downward, weakly papillose; male zone cylindrical, 6–10 mm long, 3.5–5.0 mm in diameter; stamens densely arranged, pale yellow to pink; thecae opening by elongate slit; appendix shortly stipitate, outside brownish purple to reddish, inside light yellow, elongate conical, 2.0– 3.5 cm long, 4–5 mm in diameter at base, with acute apex and truncate base. Infructescence obconical with spathe tube remaining and above the ground; fruits obconical, pinkish white with pale pinkish spots, 4–7 mm long, 2–3 mm wide, 1-seeded; seed obovate (or having constriction), at first creamy white, light brown when mature, 3.0– 3.5 mm long, 2.0– 2.5 mm wide. Etymology: —The species is named after Vietnam, the country of origin. Vietnamese name: —Bán hạ Việt Nam. Ecology: —The new species grows in clumps on open sandy soil in sparse dipterocarp-dominated forests. Different leaf forms were found in plant individuals or clumps. Flowering was seen in May to June and fruiting in July to August. The plant becomes dormant in November to April next year. Additional specimen examined (paratype):— VIETNAM. Dak Lak Province: Yok Don National Park, 01 October 2015, Nguyen Le Xuan Bach & Van Hong Thien H . T.Van 126 (SGN!). Distribution: —Ba Ria - Vung Tau Province and Dak Lak Province, southern Vietnam. Proposed IUCN conservation status: — Data Deficient (DD) (IUCN Standards and Petitions Subcommittee 2017). Typhonium vietnamense has so far been found in two protected areas (Binh Chau - Phuoc Buu Nature Reserve, Ba Ria - Vung Tau Province and Yok Don National Park, Dak Lak Province) in southern Vietnam. Although its habitat in Binh Chau - Phuoc Buu Nature Reserve is planned to be converted into a resort in the near future, the species is likely to occur in adjacent similar sparse dipterocarp-dominated forests in Cambodia. Further survey work is necessary before a definitive conservation assessment can be made. Notes: —The new species is morphologically closest to Typhonium varians but they have a number of differences as expressed in the diagnosis. Several other Typhonium species share with T. vietnamense a similar spadix structure, especially in the shape of spadix appendix and staminodes, but these are easily distinguishable: T. conchiforme Hetterscheid & Galloway (2006: 80) by deeply sagittate leaf blades, deeply cymbiform, strongly concave spathe limb and off-white or pale yellow staminodes; T. sagittariifolium Gagnepain (1942b: 11) by deeply trilobed sagittate leaf blades, erect elongate triangular spathe limb, longer spadix appendix (8 mm), and longer (3–5 mm) and recurved staminodes; and Typhonium viridispathum Galloway & Sinhabaedya (2012: 61) by bright green spathe with elongate triangular limb, off-white spadix appendix, basally white and apically pale green ovaries and white staminodes.Published as part of Van, Hong Thien, Le, Van Son, Nguyen-Phi, Nga, Nguyen, Quoc Dat, Nguyen, Tran Quoc Trung, Nguyen, Hieu Cuong & Luu, Hong Truong, 2021, A new species and a new record of Typhonium (Araceae) from southern Vietnam, pp. 201-208 in Phytotaxa 527 (3) on pages 201-204, DOI: 10.11646/phytotaxa.527.3.4, http://zenodo.org/record/575136
