본 연구는 KCYPS의 초1학년과 4학년 패널의 2차 년도에서 6차 년도 자료를 활용하여 아동 발달시기별 학대경험의 변화궤적이 어떻게 유형화되는지를 살펴보는 데 그 목적이 있다. 초1학년 패널은 2,300명, 초4학년 패널은 2,325명이 최종 분석대상이 되었다. 아동학대 변화궤적 유형을 식별하기 위해 잠재계층성장모형을 적용하여 분석을 실시하였다. 연구결과, 신체학대에서 초2~6학년에 이르는 아동기는 감소형, 낮은유지형, 증가형, 비학대형의 4개 집단으로 분류되었으며, 초5~중3학년에 이르는 초기청소년기도 같은 유형으로 분류되었다. 정서학대에서는 아동기는 감소형, 증가형, 비학대형의 3개 집단으로 분류되었으며, 초기청소년기는 감소형, 낮은유지형, 증가형, 비학대형의 4개 집단으로 분류되었다. 방임에서 아동기는 유지형, 낮은감소형, 낮은증가형, 비학대형의 4개 집단으로 분류되었으며, 초기청소년기는 유지형, 낮은증가형, 비학대형의 3개 집단으로 분류되었다. 아동의 발달시기별 학대의 증감 추이를 살펴보면 아동기에서 초기 청소년기로 신체학대가 지속되며 아동기에 비해 초기청소년기에 정서학대와 방임이 증가하는 경향을 알 수 있었다. 본 연구는 학대 유형에 따라 잠재계층분류를 시도하였다는 데 의의가 있다. 분석결과 중심으로 논의를 진행하였으며 이론적, 실천적 제언을 하였다.

This study aims to examine the effect of a change of leadership on internal environment and organization effectiveness and suggest measures on effective organizational management by analyzing a change of leadership before and after 2nd generation management. There was analysis of a difference of leadership type, organizational structure, organizational culture, management resources, job satisfaction, and organizational commitment between the period of the founders and the period of 2nd generation successors by collecting data from employees of 6 hospitals in Seoul. Also there was analysis of the effect of a change of leadership on internal environment and organizational effectiveness. According to the analysis, it was demonstrated that the factor affecting job satisfaction during the period of the founder was complexity of organizational structure, and there were no factors affecting organizational commitment. In contrast, during the period of the 2nd generation successors, it was revealed that transformational leadership, centralism of organizational structure, and human resources of management resources affect job satisfaction, and transformational leadership, complexity of organizational structure, hierarchical culture of organizational culture, and human resources of management resources affect organizational commitment. Further, after the succession from the founders to 2nd generation successors, as transformational leadership increased, job satisfaction rose, and as developmental culture was reinforced and human resources increased, organizational commitment was heightened. Furthermore, as transformational leadership increased and developmental culture was reinforced, organizational commitment was heightened. Namely, as transformational leadership was reinforced resulting from the succession to 2nd generation, employees' job satisfaction and organizational commitment increased, with circumstances aiming for the actual change.

One of the problems associated with in vitro culture of primordial gern cells (PGCs) is the large loss of cells during the initial period of culture. This study characterized the initial loss and determined the effectiveness of two classes of apoptosis inhibitors, protease inhibitors and antioxidants, on the ability of the porcine PGCs to survive in culture. Results from electron microscopic analysis and in situ DNA fragmentation assay indicated that porcine PGCs rapidly undergo apoptosis when placed in culture. Additionally, \ulcorner2-macroglobulin, a protease inhibitor and cytokine carrier, and N-acetylcysteine, an antioxidant, increased the survival of PGCs in vitro. While other protease inhibitors tested did not affect survival of PGCs, all antioxidants tested improved survival of PGCs (p<0.05). Further results indicated that the beneficial effect of the antioxidants was critical only during the initial period of culture. Finally, it was determined that in short-term culture, in the absence of feeder layer, antioxidants could partially replace the effect(s) of growth factors and reduce apoptosis. Collectively, these results indicate that the addition of \ulcorner2-macroglobulin and antioxidatns can increase the number of PGCs in vitro by suppressing apoptosis.

It was investigated whether developmental characteristics of foundation queens of Bombus ignitus collected in the 4 localities in Korea would be affected by the first oviposition days of them. The first ovipostion day was classified as 1-4 days (immediate early), 5-6days (early), 7-10 days (delayed early), 11-20 days{medium), 21- 40 days (late), and above 41 days (very late). The queen that had the early first oviposition day, i.e., laid eggs so early after starting to be raised indoors, showed much higher rate of colony foundation and progeny-queen production and much shorter period of colony foundation and worker emergence. Besides, the numbers of worker and progeny-queen emerged from the queen that had the early first oviposition day were higher than those of the queen that had the late first oviposition. In results, the queen that had the early first oviposition day could make colony stronger and could make colony formation period shorter, therefore, the first oviposition day of foundation queen was proved to be a criterion for the selection of super colonies when B. ignitus is raised indoors.

Alcohol exposure during development leads to significant long-term neurobehavior dysfunction and central nervous system alteration. The purpose of this study was to determine the effects of enriched enviroment in developmental period through motor behavior test and expression of BDNF. Neonatal rat exposed to alcohol on postnatal days 4 through 10 were studied. Female Sprague-Dawley pups were assigned to two groups. Experimental group(EG) via 4.5 g kg-1day-1 of ethanol was housed in enriched enviornment for 9 weeks. The main result of this study were as follows: 1. There was significant difference in the mean of weight change between control and experimental group. 2. In motor behavior test, there was significant difference in the mean of weight change between control and experimental group. 3. Regarding the immunoreactivity of BDNF were higher appeared experimental group than control group. In conclusion, the present results reveals that enriched enviroment in developmental period is to be extremely useful in neuronal reprganization and motor behavior improvement after alcohol exposure.

Facial cleft is not a common anomaly of craniofacial region. But it is often accompanied with cleft lip and/or palate, so it seems important to orthodontist. Facial cleft is defined as a fissure or elongated opening of the facial region, and it's etiology is the failure of the fusion of the parts which will form the face in embryonic developmental period. Facial cleft can be classified according to the time of occurrence and the area involved during developmental period. It developes 1-2.5 weeks earlier than cleft lip and/or cleft palate. In facial cleft, the deformity is generally confined to the facial region, but sometimes deformity of other body region can accompany. The interaction of the facial cleft and the genetic anomaly is not confirmed, but genetic anomaly is known to be able to occur with the patient with other anomaly of body. As an orthodontist we should know the general considerations of facial cleft and it's treatment procedures other than orthodontic treatment.

The purpose of this study is to examine perceptive change in attitude toward infancy and early childhood among university students' who were exposed to a human development lecture on infancy and early childhood. This study aims to investigate the significance of education in shaping attitudes related to child development and the importance of infancy and early childhood as developmental stages. This study also seeks to provide basic data for expanding and systematizing relevant educational programs. Fifteen university students who attended a lecture on human development were divided into four groups with three groups containing 4 members and one group containing 3 members. The following results were obtained: 1) Before attending the lecture on human development, students perceived infancy as a period dominated by feelings of helpless, indifference, and a general lack of knowledge or ability to interact with their environment; 2) Before attending the lecture on human development, students perceived early childhood as an initial period of transition that can potentially influence one's future; 3) After attending the lecture, students were better able to rationalize the developmental importance of infancy and early childhood. 4) After attending the lecture, students displayed broader understanding of the importance of early childhood on human development. This study also discusses the necessity for continuous and systematic provision of programs to help adults develop a positive perception of infancy and early childhood as a developmental process related to parenting skills.
