  • The purpose of this study is to determine a national construction industry's competitiveness and establish strategies to expand into overseas construction markets. To evaluate the international competitiveness of overseas construction businesses, this study were selected as the target range of international comparisons among the countries cited by ENR, Global-Insight, IMF, OECD, and Transparency International. In result the United States ranked first, followed by China $2^{nd}$, Italy$3^{rd}$, U.K.$4^{th}$, and Germany $5^{th}$, while Korea ranked $9^{th}$ overall. In particular, Korea's competitiveness in the construction infrastructures by country ranking($11^{th}$) was higher than the competency assessment results of construction companies by country, therein ranking $12^{th}$. In addition, while Korea ranks $12^{th}$ among 22 countries, $3^{rd}$ in price competitiveness, $12^{th}$ in construction competitiveness, and $19^{th}$ in design competitiveness.

A PHOTOELASTIC STRESS ANLYSIS IN THE SURROUNDING TISSUES OF TEETH SEATED BY INDIRECT RETAINERS WHEN APPLIED DISLODGING FORCES ON UNILATERAL DISTRAL EXTENTION PARTIAL DENTURES (편측성 후방연장 국소의치의 의치상에 이탈력이 가해질 때 간접유지장치가 장착된 치아 주위조직에 발생하는 응력에 관한 광탄성 분석)

  • The purpose of this study was to evaluate the stress distributions in the surrounding tissues of the teeth seated by indirect retainers in three different teeth of unilateral distal extension partial denture when the dislodging forces were applied on denture bases. Three dimensional photoelastic models were made. The teeth on which indirect retainers were seated were mandibular left lateral incisor (Model I), canine (Model II), and first premolar (Model III). The dislodging force with 860mg at $45^{\circ}$ angulation to occlusal plane was applied to each model. Three dimensional photoelastic stress analysis was done, and the records were diagramed and analysed. The results were as follows : The compressive stresses were shown the most on neck portions of buccal, mesial, and distal sides in all three models. Slight tensile stresses were shown on neck portions of lingual sides in all three models. The compressive stresses on buccal side were shown in strength in such order as model I, model II, and model III. The compressive stresses were shown on neck portion of mesial and distal sides of model I and mode II, with model I more than Model II. The compressive stresses were shown only on neck portion of mesial side on Model III. The general overall magnitude of compressive stresses were shown in strength in such order as Model I, Model II, and Model III.

  • This study analyzed how North Korean defectors recognized and overcame conflict in the South Korean job culture during the course of entering and settling into South Korea, and the association between their old career and adaptation within their new careers. The study selected 13 employed participants who entered South Korea more than five years ago and experienced working. Interviews were conducted over the course of five years. The topics were analyzed after performing interviews 60 to 120 minutes long by recording and transcribing the recordings and using semi-structured questionnaires for the 13 people. The results reflected the job environment in North Korea, their career background, factors for a successful new life, their constant efforts for employment, the difficult adaption to South Korean life, pursuing job stability, accepting South Korean culture, and career compromises. The results of this study are as follows. First, they undergo difficulty in the course of selecting jobs due to the converted environment from passivity to autonomy. Second, they cannot use their previous job history and they complained about prejudice and the lack of job information. Third, major problems included their lack of adaptability, stress, and loss of economic power. The study suggests that these North Korean defectors undergo an integrated course of cultural learning. Fourth, they were hardly able to adapt. Fifth, they tried to overcome conflicts of job culture according to their personal characteristics.

  • Background : North Korea's economic and public health problems began in the early 1990s as a result of the gradual loss of economic support from its communist allies, combined with an inordinate number of natural disasters. The decline in public health has increased the incidence of tuberculosis in North Koreans and refugees. This study investigated tuberculosis situation in North Korean refugees in order to prepare for the future impact of tuberculosis control in Korea. Material and Methods : From 2001 to 2005, tuberculosis patients among North Korean refugees who were diagnosed before or after arriving in South Korea, based on the official records of OO hospital, were enrolled in this study. The demographic and clinical data of the cases were evaluated retrospectively. Results : A total of 42 TB cases were reviewed during the study period. Of these, 37 (88.1%) cases were pulmonary TB. based on the cases identified among the number of North Korean refugees' arriving each year, the annual incidence of pulmonary TB were 900 per 100,000 in 2004, 700 in 2003, The number of smear-positive patients was 20 (47.6%) and the number of culture-positive patients was 18 (42.9%). Of the M. tuberculosis isolates, 2 cases were found to be susceptible to all anti-TB drugs available, 4 were resistant to isoniazid, and 3 were multi-drug resistant. Conclusion : The prevalence of pulmonary TB in North Korean Refugees is high. In addition, North Korean refugees suffer from more severe tuberculosis in bacteriological and radiological aspects.

  • Although several studies have been conducted on unification and the life of North Korean refugees, there have been few studies comparing the characteristics of North Korean refugees with South Korean workers, in terms of human resources in business administration. By considering the limitations of these prior studies, this study analyzed whether there are differences in factors affecting organizational commitment and turnover intention through a group comparative analysis between North Korean refugees and South Korean workers. For a comparative analysis between the two groups, we recruited 145 workers from North Korea and 213 South Korea-born workers. We found the following results with a multi-group structural equation model. We confirmed the measurement homogeneity by ensuring that both groups were equally aware of the measurement tools affecting organizational commitment and turnover intentions. As a result of testing the homogeneity of measurement, we also confirmed that there was a significant difference in optimism between the two groups; optimism affects organizational commitment and among social supports, affectionate support and interaction support affect organizational commitment. Analyzing the path between the two groups, we first were able to find that optimism influenced organizational commitment for both groups, in relation to positive psychological capital. However, in terms of degree, South Korean workers were found to be strongly affected. Second, with regard to social support, we were not able to find that affectionate support and interaction support have a significant impact on organizational commitment for South Korean workers, while for North Korean refugees, we confirmed that both supports have a significant impact. Third, we were unable to find any differences between the two group, in terms of other sub-components of positive psychological capital (self-efficacy, hope, and resiliency) or the sub-components of social support (informational support, tangible support). These results suggest that companies or managers employing North Korean refugee workers need to create an organizational environment that allows them to perceive social support, especially affectionate support and interaction support.

  • 인간은 출생부터 필연적으로 부모와 관계 속에서 다양한 경험을 통해 성장하고 발전하게 된다. 자녀가 세상에 태어나면서 부모와 언어적, 비언어적 의사소통을 통해 다양한 관계를 경험하면서 성장하고 발전하면서, 본인의 가치관 정립과 대인관계 형성을 위한 기초가 된다. 부모-자녀 간 원활하지 못한 의사소통이 자녀에게 정신건강 문제와 이탈, 비행과 범죄로 연결된다는 것을 많은 연구 사례가 볼 수가 있다. 이러한 선행연구를 살펴보면서 부모와 자녀 간의 원활한 개방적 의사소통이 자녀의 성장과 대인관계 형성을 하는 데 중요한 역할을 하지만, 원활하지 못한 의사소통이 이루어지면은 발전과 성장에 많은 문제를 가지고 청소년기를 보내고, 성인이 되어서도 건강하지 못 할 수가 있다. 본 연구의 목적은 중기 청소년의 성장 과정에서 자기 통제력 향상에 부모와 자녀의 개방적 의사소통이 원활할 때 중기 청소년의 발달과 성장에 영향을 줄 수 있는 자기 통제력에 대해 부모-자녀 간 개방적 의사소통의 매개 역할을 하는지를 검증하는 데 있다. 부모-자녀 간 메시지 전달이 감정교류 및 정보전달 등을 모두 포함하는 상호작용을 통해 성장과 발전을 할 수 있다는 것을 알 수 있다. 중기 청소년의 부모-자녀 간 원활한 의사소통에 영향을 미칠 수 있는 자기 통제력을 종속변수로 설정하여 본 연구를 검증하기 위해 진행하였다.
