The purpose of this study is to investigate the present conditions of the night work and shift work systems in the heavy chemical industrial complexes found in Changwon, Masan, and Chinhae. Korea. We will attempt to define and classify their problems; and to discover further ways to improve their systems. Fifty production factories were carefully selected as the subjects for this study. The shift systems were classified into five categories. The consecutive night shifts were long in almost all cases with 6 days (36 factories) and 7 days (13 factories). It was found that the night work of about] 2 hours continues for a long period in the weekly rotation full-day shift systems and the night-including non-full-day shift systems, and there was no holiday during a shift cycle in the continuous full-day shift systems. The work time in most shift systems was longer than the 44-hours/week permitted by Korean law. Considering the characteristics of these various types of shift systems, the most essential thing to reduce the shift workers' work load may be to shorten their working hours and improve the schedule of shift systems. It is highly recommended as a fundamental solution. to reduce the portal-to-portal hours from 12 to 8 in the night-including non-full-day shift systems and the weekly rotation full-day shift systems, and at least to employ a 4-team 3-shift system in the continuous full-day shift systems. In addition to this, it should from now on be taken as a goal to restructure the types of shift systems by taking such measures as avoiding continuous night work if possible, providing sufficient off-duty intervals both before and after night shift, providing increased opportunities for workers to nap during night work. and increasing the number of holidays.

Objective: This study aimed to investigate the moderating effects of peer competence between children’s perception of parenting attitudes and depression among 5<SUP>th</SUP> grade elementary students. The differences are examined based by gender. Methods: ‘The Children’s Perception of the Parenting Attitudes Inventory’, ‘Children’s Depression Inventory’, and ‘Peer Competence Inventory’ were used to collect data from 200 elementary school students from Seoul, Korea. The research hypothesis were analyzed using t -tests, Pearson’s correlation analysis, standard linear regression analysis and hierarchical multiple regression analysis via SPSS 21.0. Results: The results are as follows: First, only peer competence showed a difference between the boys and girls, where the boys scored higher than the girls. Second, there was a significant correlation between all the factors. Third, the moderating effect of peer competence on the father’s parenting attitude was supported only in the boys. Conclusion: The results denote the need of a gendered approach to understanding problems and developing counseling programs to address depression among children. They also demonstrate that high peer competence can be used to treat depression in boys dissatisfied with their father’ parenting attitude.

Die vorliegende Arbeit untersucht den Einfluss des propositionalen Gehalts auf die Äußerungsbedeutung, der als Sprechhandlung realisiert im Satzmodus oder in explizit performativen Formeln impliziert ist. Nachdem zuerst ein kurzer Überblick über die Markiertheit unter dem semantischen Aspekt gegeben wird, folgt die Erweiterung der von den Kriterien von Greenberg, Hume und Givón ausgehenden Markiertheit-Deskriptoren (Markedness Descriptors) auf die pragmatische Ebene: [±Konventionalität], [±Präferenz], [±Frequenz], [±Vorteilhaftigkeit] und [±Kontextualität]. Anschließend wird anhand Beispielen untersucht, ob (verglichen mit unmarkierten Fällen) die Markiertheit des propositionalen Gehalts die Äußerungsbedeutung beeinflusst und welche Korrelation besteht. Als Ergebnis konnte zusammenfassend gefolgert werden, dass die Markiertheit des propositionalen Gehalts die direkte Illokution explizit performativer Formeln und von Satzmodi in eine andere transferieren, und die Intention des Sprechers stärken oder abschwächen kann. Die Bedeutung der Studie liegt darin, dass die Markiertheit der Phonologie auf die pragmatische Ebene übertragen wurde und dass gezeigt werden konnte, wie der propositionale Gehalt auch die Äußerungsbedeutung beeinflussen kann.

본 연구는 가공황토 처리여부에 따른 장어시료의 품질 특성을 비교하고자 장어를 양식장에서 동일한 조건으로 사육하여 일반성분, 물성, 영양소, 기능적 특성 및 관능적 특성을 분석하였다. 그 결과 일반성분 분석에 대해서는 두 군 간의 차이가 없었으며 niacin은 실험구가 무처리 대비 더 높은 함량을 나타냈다. Tocopherol은 가공황토소재로 양식한 시료에서 무처리구 대비 약 3배 이상의 tocopherol 함량이 측정되었다(P<0.05). 냉?해동 저장기간 동안 실험구가 무처리구 대비보다 안정된 조직감을 나타냈다. DPPH 라디칼소거능과 FRAP value 분석 결과, 실험구의 항산화 활성이 유의적으로 높은 것을 확인할 수 있었다. 묘사분석 결과 ‘기름진 정도’가 무처리구에 비하여 실험구에서 낮게 평가되었으며, 이는 보다 담백하면서 기능성이 강화된 장어의 생산이 가능함을 나타낸다고 할 수 있다. 따라서 친환경 가공황토소재로 양식한 장어의 경우 기능성이 강화되고 맛이 향상된 고부가가치 제품으로 생산이 가능하여 국내 장어 시장을 한단계 업그레이드할 수 있을 것으로 사료된다. The objectives of this study were to examine the effects of red clay-processed nano-materials (RCPM) on the quality characteristics of eel (Anguilla japonica). Both eels treated with RCPM and control were farm-raised under identical environments and were commercially processed. General components, texture, nutrients, antioxidant activities, and sensory analysis were performed. RCPM-treated eels showed significantly higher DPPH radical scavenging activities and FRAP values than the of control, indicating higher antioxidant activities of eels raised by RCPM. The amounts of niacin and tocopherol in RCPM-treated eels were higher than those of the control. For analysis of freeze-thaw stability, RCPM-treated eels showed more stable texture over freeze-thaw three treatment cycles. Descriptive panelists perceived eels raised by RCPM to be less oily than the control. Overall, RCPM exhibited positive effects on the quality of farm-raised eels. Therefore, RCPM would be of benefit to produce high value-added eels of premium quality.
