  • The purpose of this study was to evaluate changes in soft tissue chin thickness and to investigate correlations between hard and soft tissues measurements after orthodontic treatment conducted by premolars extraction and incisor retraction. The sample consisted of 35 female adults with Angle classification class I or class II division 1 malocclusion. Using lateral cephalometric radiographs taken before and after treatment, hard and soft tissue structures were measured and reproducible six landmark on soft chin tissue were used to locate the various points of soft tissue contour of the chin. The res에ts were as follows : 1. There were signigicant correlations between pretreatment B-B', Pm-Pm' and pretreatment vortical skeletal measurements such as $MP{\perp}HP,\;MP{\perp}PP$, ALFH and between a-a', b-b', Me-Me' and measurements of sym-physeal morphology such as SL, SW, PL. 2. There were significant decreases at B-B', Pm-Pm' and significant increases at a-a', b-b' between pre-and posttreatment mea surements. 3. There were significant correlations among soft tissues changes and hard tissue changes except for changes at B-B' and the range of correlation coefficient was about 0.3-0.4. 4. There were significant differences at ${\Delta}UI-VP,\;LI{\perp}, and B-B' measurements between subgroups divided by posttreatment Pog-Pog' changes. 5. There were significant differences at ${\Delta}overbite,\;NPog{\perp}HP,\;and\;Me-Me'$ measurements between subgroups divided by posttreatment Me-Me' changes.

  • The purpose of this study was to make a further analysis on potential correlations of male spouses' role performance (daily life assistance, sexual life satisfaction and marital conflict) and their marital stability in international marriage. In order to meet the purpose, this study used a questionnaire form to survey Korean men who married and kept a marital relationship with foreign brides (survey dating from Dec. 12, 2010 to May. 3. 2011). Out of total 300 sheets of questionnaire form distributed to a population of those men, 247 sheets of questionnaire form were collected from them. Then, total 220 sheets of complete and valid questionnaire form except incomplete 27 sheets were finally selected for statistical data analysis. Major findings of this study can be summed up as follows: First, in terms of role performance, it was found that group with more daily life assistances had higher marital stability than group with less daily life assistances. Accordingly, it was found that daily life assistance was correlated with marital satisfaction. Secondly, in terms of role performance, it was found that group with more marital conflicts had higher marital stability than group with less marital conflicts. Based on these findings, it is concluded that male spouses' positive role performance in international marriage has positive effects on marital stability in relationships with their foreign female spouses.

  • The purpose of this study is to examine how the workplace bullying recognition level of an employee in Korean foodservice industry, which more strongly depends on human services than other industries, influences on job satisfaction and turnover intention. To this end, we collected 250 samples of employees working in the kitchen of family restaurants. Among the collected 250 sample, 241 samples were usable for the analysis excluding 9. The result is as follows. Firstly, there is a difference in average of satisfaction in work according to each group of causes to recognize workplace bullying. That is, the group which vaguely recognizes bullying as for threat to professional status and isolation, and psychological harassment shows higher satisfaction in work than the group which recognizes the bullying well, which is statistically significant. The latter demonstrates more turnover intention than the former. Secondly, the research examining the effects of the causes of workplace bullying over the employees' satisfaction in work and turnover intention shows the following result. The causes to recognize workplace bullying of the employees have a negative effect(-) on job satisfaction on the whole. The causes to recognize workplace bullying of the employees have a positive influence(+) on turnover intention. In conclusion, manager in foodservice industry will need to provide employees with the environment which can help staff improve cooperation, unity and solidarity within the organization.

  • 어린이들이 자라나면서 인지지능발달도 중요하지만 현대를 살아가는 훌륭한 성인으로서 성장하여 사회나 조직 속에서 보다 성공적인 삶을 살아가려면 정서지능의 발달은 매우 중요하다. 어린이의 정서지능발달이 농촌체험을 통해서 이루어진다면 농촌측면에서 1석2조의 효과를 가져올 수 있는 것이다. 도시의 어린이들이 농촌체험을 하면서 정서지능을 키워갈 때, 우리 농촌에서는 농촌과 농업의 중요성을 알리고, 체험소득을 얻을 수 있기 때문이다. 따라서 본 연구의 목표는 농촌체험의 정서지능 향상 효과를 구명하는데 있다. 연구방법은 서울시 교육청에 지원학교 가운데 1개 학교를 선정하였으며, 대상학교의 5학년 2개 반 아동 중에 체험지원 아동 30명을 실험집단으로 선정하고, 같은 학교 같은 학년 1개 반 아동 30명을 비교집단으로 선정하였다. 조사도구는 청소년용 EQ검사 척도를 활용하였으며(문용린, 1999), 전혀 그렇지않다(0점)부터 매우 그렇다(4점)까지 총 40개 문항으로 구성되었다. 자료수집방법은 실험집단과 비실험집단 학생을 대상으로 사전 및 사후 질문지 120부가 활용되었다. 분석방법으로는 평균, 표준편차, 공분산분석, 독립표본t-검증, 대응표본t-검증이 활용되었다. 적용 체험프로그램은 초등학생을 대상으로 총 9회차로 포도이야기, 참새와 방앗간, 버섯따기 체험, 고구마 캐기, 허브도감만들기 등과 같은 농촌체험프로그램을 실시하였다. 연구결과 실험집단과 비실험집단에 대한 사전 정서지능 측정에서는 실험집단과 비교집단의 정서지능이 차이가 없는 것으로 나타났다. 농촌체험프로그램을 실시한 후 사후검사에서는 실험집단(99.76)이 비교집단(97.79)보다 정서지능이 높게 나타났다. 실험집단의 정서지능의 농촌체험프로그램 사전 및 사후 결과 정서지능이 총점이 평균 7.08 정도 향상된 것으로 나타났으며, 정서지능에 사전 및 사후 결과의 평균을 하위 영역별로 살펴보면 '정서인식'이 1.76, '사고촉진'이 3.32, '정서지식'이 2.40정도 향상되었다. 하지만 비교집단의 정서지능은 사전과 사후간의 유의한 차이가 없어서 정서지능의 변화가 없는 것으로 나타났다. 결론적으로 농촌체험프로그램을 지속적으로 9회 실시한 후 사전 및 사후 정서지능 검사에서 체험집단이 비체험집단보다 6점이나 더 높게 나타나 농촌체험을 통하여 정서지능 향상에 효과 있음이 구명되었다. 이 결과를 토대로 농촌체험은 정서 지능향상에 효과를 주고 있다고 할 수 있다. 앞으로 이러한 결과가 우리 농촌관광마을이나 체험농장에 홍보자료로 활용되었으면 한다.

  • This study employed inter-simple-sequence repeat (ISSR) to assess genetic variation among 189 individuals representing 10 populations (nine in Korea and one in Japan) of Millettia japonica, which has recently been lifted from the endangered species of Korea. The calculated Shannon's information index value (I = 0.2689) of the species was appreciable and was higher than other endangered leguminous woody taxa. Gochang (I = 0.2968), Namhae (I = 0.2951), and Mt. Toham (I = 0.2823) populations showed relatively high genetic diversity, whereas the Kyushu (in Japan) population (I = 0.2487) exhibited the lowest. The results of an analysis of molecular variance indicated that 86.49% of the diversity was attributed to within populations, and 13.51% to differences among populations, suggesting that M. japonica populations do not have significant geographic differentiation and that the gene flow between populations exists to some extent (Nm = 1.8446). Continuous habitat monitoring should be conducted to conserve genetic diversity of M. japonica, particularly for those populations with relatively high genetic diversity. Selection of many individuals from the populations in Gochang, Namhae, and Mt. Toham is thought to be an appropriate strategy for ex situ conservation of M. japonica in Korea.
