Underpricing signifies that IPO share prices do not reflect the fundamental value of the listed company. Corporate governance plays an essential role in IPOs where the board of directors, the independent board of directors, and the board of supervisors are significant elements of accurate share pricing. The study investigates the underpricing phenomena and short-term performance of the IPO companies during the listing process in the Ho Chi Minh Stock Exchange (HOSE). The work outcomes illustrate the role of the corporate organizational structure in the period of the IPO process that may attract potential investors. The hypothesis testing is conducted with a multiple regression model including 100 observations from enterprises doing IPO listed on HOSE. The study results generate signals for the investors and regulators that the board of directors holds a strong negative influence on the underpricing process. Secondly, the level of the independent board of directors and stock exchange in itself has no significant impact on the underpricing process. Underpricing is one of the many anomalies of the stock exchanges that provide wrong signals for the market participants. Identifying stock prices that reflect their intrinsic value is an ongoing debate among scholars, investors, and other market participants.

본 논문에서는 4×2 미앤더라인 배열 구조를 이용하여 8 dBi 이득을 유지하는 광대역 이중 다이폴 준-야기 안테나에 대하여 연구하였다. 4×2 미앤더라인 배열 구조는 미앤더라인 도체 모양의 단위 셀로 구성되며, 이중 다이폴 준-야기 안테나의 두 번째 다이폴 안테나 위에 배치하였다. 일반적으로 많이 사용하는 여러 개의 스트립 도파기를 사용한 경우와 동일한 크기의 FR4 기판에 설계하였고, 입력 반사 계수와 이득 특성을 비교하였다. 비교 결과, 기존의 다중 스트립 도파기를 사용하였을 때 보다 주파수 대역폭이 6.3% 증가하였고, 이득이 8dBi 이상인 주파수 대역폭은 10.1% 증가하고 평균 이득도 조금 증가하였다. 제작된 안테나의 전압 정재파비 (VSWR; voltage standing wave ratio)가 2 이하인 대역은 1.548-2.846 GHz (59.1%)이고, 1.6-2.8 GHz 대역에서 이득이 8 dBi 이상으로 측정되었다.

The purpose of this study was to investigate the effect of childcare teachers' ego-resilience and directors, co-workers and family's social support to childcare teachers' burnout. The participants in this study were 326 childcare teachers from Daejeon metropolitan city and Chungnam province. They responded to the 'Maslach Burnout Inventory', 'Ego-resilience Scale', and 'Social Support Scale'. The collected data were analyzed by t-test, one-way ANOVA, Pearson's productive correlation, stepwise multiple regression, Duncan test for post hoc test, Cronbach's ${\alpha}$ for reliability, and factor analysis for validity by SPSS PC program (18.0 version). The results were as follows; first, there were significant differences in childcare teachers' burnout scores in relation to the educational levels of childcare teachers, their working hours, children's number per class, and the ages of the children they teach. Second, there were significant negative correlations (r = -.11~-.62) among childcare teachers' ego-resilience, directors, teaching colleagues and family's social supports, and their levels of burnout. Finally, childcare teachers' ego-resilience and teaching colleagues' levels of social support helped explain about 43% the childcare teachers' burnout total scores and about 17~39% of their sub-scores.

This study examines the relationship between board characteristics and capital structure. Data was collected from the annual reports of listed companies in the Stock Exchange of Thailand, from 2015 to 2017, which totaled 1,264 firm-year observations. The study uses multiple regression analysis to analyses the data by using independent variables, including board size, outside directors, managerial ownership, CEO duality, frequency of board meetings, board experience, and gender to measure board characteristics and the total debt ratio for capital structure. Research findings show that the more independent the directors are, the lower the cost of debt financing is, as they control the management team more strictly about debt financing than directors with less independence do. Additionally, the results reveal that the higher the percentage of managerial ownership, the higher the level of leverage and debt financing, whereas board size and board meetings have a negative relationship to capital structure. Further research showed that firm size, growth opportunities and corporate governance rating all had a positive significant impact on capital structure. The findings of this study suggest that the presence of proper corporate governance leads to better funding mechanisms as it ensures that the company is in a better position to obtain external funding.

본 연구는 유아교육기관장인 원장의 감성리더십이 조직문화와 어떤 상관이 있으며 설명력은 어떠한지 알아보며, 감성리더십 수준에 따라 조직문화수준에 차이가 있는지 알아보고자 실시되었다. 서울시와 수도권의 유치원과 어린이집에서 보육교사 164명을 대상으로 원장의 감성리더십과 조직문화에 대한 설문지를 각각 실시하였다. 회수된 자료는 spss 23.0 프로그램을 활용하여 상관관계와 회귀분석과 t-test 분석을 실시하였다. 그 결과를 살펴보면 다음과 같다. 첫째, 기관장의 감성리더십의 자기인식능력, 자기관리능력, 사회적인식 능력, 관계관리 능력 등 모든 하위요인과 조직문화의 모든 하위요인인 인적자원 문화, 개방체계 문화, 위계질서 문화, 생산중심 문화 요인은 밀접한 상관이 있음을 알 수 있었다. 조직문화를 설명하는 기관장 리더십에 대한 회귀분석의 결과는 인적자원 문화와 위계질서 문화는 관계관리 능력 리더십이 의미있는 설명력을 보였으며, 개방체제 문화는 자기인식 능력 리더십, 생산중심 문화는 사회인식 능력 리더십이 의미있게 설명하는 것으로 나타났다. 마지막으로 기관장의 리더십 수준이 높은 집단의 조직문화의 성향점수는 기관장의 감성리더십이 낮은 집단보다 조직문화의 성향점수가 더 의미있게 높은 것을 알 수 있었다. 본 연구결과에 따라 기관장의 리더십은 조직문화와 밀접한 상관이 있으며 의미있는 영향력을 나타낸다는 것을 알 수 있었으며 이에따라 기관장들의 감성리더십에 대한 중요성이 강조되어야하며 리더십 수준을 높일 수 있는 방안이 필요함을 시사한다.
