이 연구는 정상 교합과 양호한 안모를 가진 169명의 남자와 174명의 여자 아시아 각국 인을 대상으로 연조직 측모의 특징을 비교 분석하기 위하여 시행되었다. 100명의 한국인, 100명의 중국인, 72명의 월남인 및 71명의 일본인으로부터 촬영된 측모두부방사선사진 상에서 9개의 계측점을 설정하고 전산 입력한 뒤 6 개의 연조직 계측 항목에 대한 측정을 시행한 후 통계 처리하였다. 분산 분적에서 중국인의 총 측모(GI'-Pr-Pg')는 한국인이나 월남인에서 보다 적은 돌출도를 보였다(P<0.01). 중국인의 안면평면측모(GI'-Sn'-Pg') 역시 월남인 보다 적은 돌출각을 나타내었다(P<0.01). 홀더웨이의 하순각(Pg'-LS:N-B)은 월남인에서 가장 컸고 다음으로 중국인, 한국인, 일본인의 순으로 크게 나타났다. 월남인의 상순은 중국인에서보다 리???츠의 심미적 기준선에 더 많이 근접하였고 한국인과 일본인에서의 상순은 기준선보다 후방에 위치하였다. 한국인과 일본인의 하순은 심미적 기준선에 근접한 반면 중국인과 월남인의 하순은 기준선 보다 2 mm 전방에 위치하였다. 한국인과 월남인의 비순각은 중국인과 일본인에서 보다 큰 것으로 나타났다. 남녀 간의 성차는 기본적으로 코의 높이에서 상이하였고 이로 인하여 여자에서의 총 측모각과 비순각이 남자보다 크게 나타났다(P<0.001). 이러한 결과는 아시아 각국인 들의 연조직 측모에 대하여 단일 표준치에 의한 분석 평가가 적절하지 않으며 각 인종별 표준치 설정의 필요성을 시사한다.

Purpose: This study was conducted to generate a grounded substantive theory of the adaptation process of mothers-in-law of Vietnamese women married to Korean husbands. Methods: Thirteen women who had Vietnamese daughters-in-law were interviewed. Data were transcribed verbatim and analyzed using a grounded theory method. Results: Eight categories with 19 sub-categories were extracted from 268 concepts. The identified phenomenon was 'overcoming differences' and the core category was 'trying one's best to live together with daughter-in-law'. The 9 categories were grouped into 3 stages for the adaptation process: encountering, struggling, and living together. Conclusion: The results indicate that when individuals from different cultural and personal backgrounds have to live together there is a continuing negotiation process towards meeting each other's needs. Health professionals can assist this adaptation process by providing these women with insights into various ways of meeting each other's need while they are struggling.

Purpose: To identify the effects of spousal support on the relationship between acculturative stress and sense of parenting competence among married Vietnamese immigrant women. Methods: The sample for this study consisted of 175 married Vietnamese immigrant women in Gyeongsangnam-do. Data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlations, and hierarchical multiple regression with SPSS/WIN 23.0. Results: (a) sense of parenting competence was negatively correlated with acculturative stress, whereas a positive correlation was observed with spousal support; (b) spousal support mediated the relationship between acculturative stress and sense of parenting competence. Conclusion: Results of the study suggest that spousal support decreases the negative effects of acculturative stress on sense of parenting competence. Therefore, we need to find ways to strengthen spousal support for married Vietnamese immigrant women.

The research aims to investigate the determinants of the financial performance of 1343 Vietnamese companies categorized into six different industries listed on the Vietnamese Stock Exchange over a four-year period from 2014 to 2017 using STATA software. Those determinants include firm size, liquidity, solvency, financial leverage, and financial adequacy while the financial performance is evaluated by three different ratios: return on assets (ROA), return on equity (ROE), and return on sales (ROS). The research results from these companies during the given period indicate that: (1) Firm size has a positive impact on both ROA and ROS, especially ROA but it has the opposite effect on ROE, (2) Adequacy ratio impacts positively on ROA and ROS but negatively on ROE, (3) Financial leverage considerably negative influences on ROE and ROS but positively impacts on ROA, (4) Liquidity has a positive effect on both ROA and ROE but a negative one on ROS and (5) Solvency has a positive impact on ROA and ROS but the negative impact on ROE. Furthermore, agriculture accounted for the highest percentage of profitability at the beginning, which was replaced by service for ROA but manufacture for ROE from 2016 to 2017 as opposed to the least in transportation.

Purpose: The study was undertaken to see whether the culturally sensitive education for perinatal care using a face to face approach improves understanding of spouse's culture, knowledge of pregnancy and parenting skills, and self-efficacy among Korean husbands and Vietnamese wives. Methods: This study has a pre- and post-test study design conducted in a total of 13 couples who live in Seoul and agreed to participate. The education program consisted of lecture and hands on practice. The self-administered questionnaires and the checklist developed based on the educational purpose were used to assess the education effects. Results: The knowledge scores on Korean/Vietnamese culture, pregnancy and parenting skills as well as the performance scores on hand washing, pelvic strengthening, feedings and newborn bathing techniques were significantly improved in both husbands and wives after education, but pelvic floor exercises were improved only in wives. Conclusion: Overall, the individual education for culturally sensitive perinatal care was effective in our study participants.

This paper examines the impact of gender on access to debt finance among Vietnamese enterprises. The paper investigates data and variables retrieved from the World Bank Enterprise Survey dataset using five Probit models. The regression results suggest that there exist more unfavourable debt financing conditions for women-led firms (WLF), measured as a lower probability of having loan applications fully approved. Firm's age, working sector, and perception of access to finance as a difficulty are found to have explanatory power on the discrimination. More importantly, the perception of debt finance as a difficulty or firms' level of confidence significantly explains the variance of the dependent variable of probability of loan approval, or gender effect would be more pronounced if the firm already has a low level of confidence. The paper also contributes in testing for the gender effect on Vietnamese enterprises from different sectors and scale, unlike other prior research papers focusing on specific sectors and/or small and medium enterprises only. The findings are highly useful for Vietnamese credit institutions to set out a specific business policy to attract more WLFs and help promoting gender equality in the working environment, especially in debt financing, which is often neglected in existing regulation and policy frameworks.

Purpose: To understand the meaning and essence of Vietnamese migrant women's maternal experience after childbirth. Methods: A phenomenological methodology was used for this study. Study participants were six Vietnamese marriage migrant women who had experience of childbirth in Korea. Data collection period was from February 1 through November 4, 2016. Data were collected through in-depth interview and analyzed with the Giorgi method. Results: As a result of study, six main meanings and 12 themes were produced. The six main meanings produced in this study were 'childbirth realized in the double difficulty', 'concerned health between the ở cữ and the sanhujori', 'tired body with hard parenting', 'crowding regret for international marriage after childbirth', 'Grateful partner becoming the prop', and 'Growing maternal instinct by moving the mind and body in a foreign country'. Conclusion: Consideration for postnatal care is necessary from Vietnamese marriage migrant women's viewpoint. Systematic education programs that can improve nursing capability of medical personnel for multicultured clinical practice with development of a postnatal care program suited to multiculture are also necessary.

Accounting information disclosure by enterprises is important for third-party entities (suppliers, creditors, banks, regulators, etc.). Voluntary accounting information disclosure (VAID) refers to additional information related to business activities shown on the annual report above and beyond the required information about business results and financial position as well as cash flow. This supports the stakeholders gaining useful information to make proper business decisions. The article examines the influence of ownership structure on the voluntary accounting information disclosure of the top 100 Vietnamese listed companies (VN100). Data collected by authors on regular annual reports totaled 425 observations from 2015 to 2019. The article uses OLS to test multivariate regression models with time-series data. The research results show that there are three variables affecting voluntary accounting information disclosure, of which foreign ownership and institution ownership have a positive impact, while concentration ownership has an opposite impact. Accordingly, the managers of VN100 should raise awareness in order to demonstrate the obligation of information providers to users to ensure clarity and completeness. The state agencies should encourage VN100 to enhance voluntary accounting information disclosure. This contributes to improve the information level of Vietnamese listed companies to embrace the trend of international economic integration.
