목 적: 일중선호도는 하루 중 어느 시간대에 각성도가 높고 활기찬 지에 대한 경향으로 아침형-저녁형이라고도 알려져있다. PER3 유전자는 일중선호도에 영향을 주는 것으로 알려져 왔다. 본 연구에서 우리는 젊고 건강한 피험자들에서 환경과 혼란요인들을 통제하고 PER3 유전자 다형성과 일중선호도간에 연관을 연구하였다. 방 법: 연구에 참여한 대상자는 299명의 의과대학생들(남자 299, 여자 191명)이며 평균연령은 22.9세였다. 일중선호도는 13개 문항의 Composite Scale for Morningness (CSM)로 측정하였다. PER3 VNTR(rs57875989)의 유전자형분석은 중합효소연쇄반응법을 사용하여 이루어졌다. 양측검정으로 유의수준은 p<0.05로 하였다. 결 과: 전체 대상자에 대한 CSM 점수는 31.90${\pm}$6.39 (평균${\pm}$표준편차)였다. 남녀간에 CSM 총점에 유의한 차이는 없었다. PER3 5R/5R에서 CSM 점수가 높은 경향을 보였으나, PER3 VNTR(rs57875989) 유전자형과 대립유전자에 따른 CSM 점수의 유의한 차이는 없었다. 결 론: 본 연구는 젊은 건강한 한국인에서 PER3 V- NTR과 일중선호도간의 연관을 입증하지 못했다. 향후 보다 대규모의 피험자들을 대상으로 PER3의 여러 유전자들에 대해 다형성과 일중선호도간의 연관에 대한 연구가 필요할 것으로 생각된다.

본 연구는 부산, 대구, 광주, 대전 등 4개 대도시권역을 대상으로 대중교통서비스가 열악한 대중교통사각지역을 선정한 후 이들 지역간을 운행하는 새로운 급행대중교통수단 도입 시 기성 시가지내 통행자들과 수단선택 행태가 어떻게 다른지를 분석하기위해 SP 조사(stated preference survey)를 통한 수단선택 행태변화에 대해 네스티드 로짓모형을 구축하여 분석하였다. 연구결과 대중교통사각지대는 잠재 대중교통수요가 많아 기성시가지에 비해 자가용통행으로부터 새로운 대중교통수단으로 전환하는 통행전환 비율이 매우 높은 것으로 분석되었다. 이러한 연구결과는 향후 대도시권 외곽 순환도로 혹은 외곽지역에서 도심지역으로 연결되는 간선도로를 활용한 새로운 급행 대중교통체계 도입시 수요변화 평가와 외곽지역의 대중교통 잠재수요 분석에도 활용될 수 있을 것으로 판단된다.

Purpose: The purpose of this study was to assess the association of vocational interest and personality with temporomandibular disorders (TMD). Methods: Four hundred and fourteen college students in Gyeonggi-do completed Vocational Preference Inventory L form and a questionnaire and collected data were analyzed by R program. Results: The percentage of subjects who responded that they had at least one contributing factor for TMD was significantly different among 27 two-letter Holland codes (p<0.05). The two-letter Holland codes of which the first-letter was social (S) (S artistic [A], S investigative [I], S realistic [R], S conventional [C], S enterprising [E]) or C (CE, CS, CA, CI) had tendency of having the relatively higher prevalence of symptoms and contributing factors for TMD. Among 6 one-letter Holland codes, the prevalence of a symptom of frequent fatigue in the jaw and a habit of gum chewing showed the significant difference (p<0.05). E code seemed to have lower prevalence of a symptom of frequent fatigue in the jaw than other codes. S code appeared to use chewing gum more frequently than other codes. High scorers on emotional instability showed the significantly higher prevalence of TMD symptoms (p<0.05) and contributing factors for TMD (p<0.001) than low scorers. Furthermore, high scorers on emotional instability had significantly higher mean scales of the number of positive answers of TMD symptoms (p<0.01) and of contributing factors for TMD (p<0.001) than low scorers. Conclusions: Symptoms and contributing factors for TMD were related to emotional instability. Vocational Preference Inventory L form might be utilized in assessing emotional factors of persons with TMD symptoms.

This study was conducted to investigate the vegetable eating behaviors and preferences of elementary school students by stage of change for vegetable intake. The subjects consisted of 191 fourth and fifth grade elementary school students from Gyeonggi province. The stage of change for vegetable intake was categorized into three groups: precontemplation (PC, 18.4%), preparation (P, 43.5%), and action/maintenance (A&M, 48.2%). The trend to eat a variety of foods was more distinctive as the students went from the PC to the A&M stage. The stage of change for vegetable intake was closely related with the kimchi-eating pattern of the students. The A&M group ate more vegetables than the PC group because they liked vegetables and/or wanted to prevent disease. The PC group had a lower tendency to follow recommendations for vegetable eating than the P and A&M groups. The PC group also had an incorrect notion that low vegetable consumption over an extended time would not have a big impact on their health. The vegetables of high preference for the elementary school students were potato, sweet potato, lettuce, radish, perilla leaf, cucumber, and cabbage. The vegetables of low preference were spinach, onion, balloon flower, and green pepper. The PC group had lower preferences for most vegetables than the P and A&M groups. Therefore, careful nutrition education is necessary especially for students in the PC group in order to explain the positive effects of vegetable intake and negative effects of an unbalanced diet. It is also necessary to survey students' tastes consistently and to develop recipes that encourage them to consume more vegetables agreeably.

According to the research taken by the National Statistical Office, the fertility rate of a Korean fertile female is 1.17. This figure is the lowest in the world, and the reduction in the fertility rate over the last 30 years was the biggest in the world. It can be seen as a warning alarm about the effects of a low birth rate and a silver society. Assuming that there are several factors involved in this phenomenon, this study inquired into the attitude towards children, attitude towards nourishing children, attitude towards sex roles and the harmony between the jobs and families of married females, and examined the factors that influence the willingness to give birth. Final 581 copies of the survey questionnaire were used for analysis and the collected data were analysed by SPSS, Pearson's correlation analysis, t-test, ANOVA, and Duncan's Multiple Range Test. Three main conclusions were reached: Firstly, the value variables, such as sex-role attitudes and the preference for work or home, affect the willingness to give birth. Therefore, it can be said that one's values have a significant effect on these variables and the willingness to give birth. Secondly, both working morns and housewives have a strong tendency to give a birth if they are supported on child rearing. Finally, the employment of the married women itself can be a variable that can affect childbirth. In other words, the working hours affect employed married women so as sex-role attitudes, the preference between work and home, ideal number of children, and the income to housewives. Also, even in whole married women, the employment itself can be a major factor of the willingness to have a baby. Therefore, unemployed married women have more of a tendency to have children than employed married women.

This study was carried out to clarify the effect of addition of green tea powder on Dasik quality. The green tea powder was added as the ratio of 0%, 2%, 4%, 6% and 8%, respectively. The physio-chemical analysis and sensory test on the Dasik were performed. The flour and starch Dasik added to green tea powder showed lower moisture content compared to the non-added treatment, but the ash content was higher in the added Dasik. At the color test, Dasik of green tea powder showed lower L, a, and b value than the non-added treatment, respectively. These values were greatly decreased as the amount of green tea powder was increased. Addition of green tea powder had a tendency to show high hardness, cohesiveness, springiness, and gumminess but brittleness was low in the non-added treatment. Therefore, addition of green tea powder made Dasik texture more dense, and this tendency of texture was distinct at the flour Dasik compared to the starch Dasik. At the sensory test, surface color and green tea flavor were strong as the adding amount of green tea was increased, but sweetness was weak. There were not significant differences in the overall preference among 0%, 2% and 4% treatments, but the preference was greatly decreased from the above 6%. In conclusion, 4% addition of green tea powder would be the useful method to enhance quality of Dasik, and the flour Dasik showed better result than the starch Dasik.
