In addition to the development of functional cosmetics, technology to increase percutaneous absorption rate when applied to the skin is an important task. In this experiment, oleic acid was used as a skin absorption promoter, and its effect on transdermal permeability of adenosine was studied and analyzed using a skin-like membrane. As a result of the experiment, it was investigated that the permeability coefficient and concentration of adenosine are proportional to the content of oleic acid. This indicates that a high proportion of oleic acid is effective as a skin absorption promoter.

Objectives:Hypothalamic-Pituitary-Adrenocortical(HPA) system dysregulation plays an important role in the pathophysiology of major depressive disorder. Medically unexplained somatic symptoms comprised the predominant complaints of korean patients with major depressive disorder. It might be related to dysregulation of HPA system and somatic symptoms. The aim of this study was to investigate the association between Hamilton Depression Rating Scale severity and the Plasma Adrenocorticotropic Hormone(ACTH) & Serum Cortisol level in Korean patients with major depressive disorder. Methods:Our study design was prospective. A total 111 hospitalized patients with major depressive disorder (DSM-IV) at Anam Hospital, Korea University Medical Center between Jan 2009 and May 2011 were selected. Hamilton Depression Rating Scale was measured by psychiatrist. Plasma ACTH, Serum Cortisol levels were analyzed at the time of admission. Results:There are significant correlations(p<0.05) between Hamilton Depression Rating Scale of somatic component(HAM-D 11-15 item) and Plasma ACTH and Serum Cortisol level. However, other HAM-D sub items were not significantly correlated with Plasma ACTH and Serum Cortisol level except somatic component. Conclusion:Our Study results suggest that hyperactivity of HPA axis might be correlation with somatic symptoms in korean patients with major depressive disorder.

This study was conducted to examine the feature of attachment and the main factors of attachment development between autistic child and his or her mother. Data was collected at Day Care Center for Children with Developmental Disorder in S National University Hospital through nurses's in S National University Hospital through nurses's participating observation, interview with the mothers, and review of nursing records, from April 2 to June 30, 1994. The subjects were all 6 children, one was a girl, the others were boys, and their mothers who participate at the sensory-integrative play for attachment promotion served at this center. Content analysis was done for data analysis. First, all data were categorized by main concepts, reciprocity and affect. Then these wee analyzd and discussed on the aspects of specificity, proximity, synchrony, joint attention, strong affect, emotional availability which were chosen as the components of attachment through literature review. The results of this study were summarized as follows : all subjects were underdeveloped, unstable and showed different level of mother-child attachment. But during the program their attachment behaviors improved little by little. The behaviors which represented specificity, proximity, and strong affect were increased considerably, on the other hand the behaviors which represented joint attention and emotional availability were scarce. The more mother and child had contact and interacted merrily, the more their attachment behaviors developed. Another important factors of attachment development in these cases were mother and child's each characteristics. Especially the child's autistic peculiarity, such as indifference, severe resistance, distracterbility, stereotype tendency, physical condition were major barriers of maintatining the mother-child interaction. Also mother's attitude to her child, raring skill and physical condition were influencing factors. A few mothers who were anxious and stubborn had much more difficulty to adjust to their children. The mother who had experienced happiness with her child, especially if the mother experienced more fun at the play by herself became more positive, active and flexible, and that mother-child interaction maintained much longer and improved. It was more critical to help them enjoy their interaction. Thus nurses had to plan and intervene more joyful and various play, and consider mother's need in addition to child's need. And The program should be strengthened to support the mother emotionally to maximize the therapeutic effect.

An experimental study on the pressure losses of air through the municipal solid wastes, either dry or wet, has been carried out in this study. Generally the pressure loss increases as the air velocity and depth of solid wastes increase. However, there are some unexpected phenomena for the dry wastes with high air velocity and low depth due to the strong floating effects of solid wastes. Such effects are also shown in wet wastes when the moisture content is not sufficiently high. The results of this study are useful in designing the dimension of second combustion chamber of multi-stage combustion incinerator.

목 적 : 경골 골절에서 골수정 고정술후 발생하는 교합나사 파단의 빈도와 발생 원인을 밝히고자한다. 대상 및 방법 : 1995년 3월부터 2000년 10월까지 골수정으로 치료하였던 경골 간부골절 82예중 내고정물 파단이 발생하거나 골유합이 이루질 때까지 추시 가능하였던 75예를 대상으로 하였다. 내고정물 파단 빈도와 위치, 골절의 양상, 술후 골절부 신연 및 골유합 이상 여부를 조사하였다. 결 과 : 교합나사 파단은 7예였고 (9.3%), 근위부 두 번째 나사의 파단이 가장 흔하였다. 교합나사으 ㅣ파단은 AO분류 B형과 C형 골절, 술후 골절부가 신연된 경우, 개발성골절, 자연유합 및 불유합의 경우 발생하였다. 결 론 : 교합나사 파단의 주된 요인은 골절부의 골과 골 접촉이 불안정하기 때문이며, 개방성 골절, 지연유합 및 불유합도 교합나사 파단의 위험인자라고 생각한다. 교합나사 파단을 예방하기 위해서는 수술시 골절부 신연을 피해야하며 골절부 골접촉이 불안정한 경우 완전 체중부하를 골유합시까지 제한하여야할 것으로 생각한다. Purpose : The aims of this study were to investigate the prevalence and the causes of crew breakage in tibia nailing. Materials and Methods : Between 1995 and 2000, eighty-two tibial diaphyseal fracture were treated with interlocking nails. The loss of follow-up was 7 cases. We retrospectively reviewed seventy-five cases. We investigated the rate and location of metal failure and evaluated the fracture pattern, the presence of distraction after nailing and union abnormality. Results : Screw breakage was identified in seven cases (9.3%) and most frequently occurred on the second proximal locking screw. Screw breakage occurred in AO type B or C type fractures, fracture site distraction after nailing, open fracture, delayed union and nonunion. Conclusion : The main cause of screw breakage is unstable bone to bone contact on the fracture site caused by comminution of distraction. The open fracture, delayed union, and nonunion also contributing factors for screw breakage. For preventing screw breakage, it is necessary to avoid fracture site distraction and delay full weight bearing in cases having unstable fracture site contact.

의미망 활동과 수준별 학습을 통한 영어 독해력 향상 방안 : Focusing on semantic mapping and leveled group activities

임병빈,장세숙 한국영어어문교육학회 2001 영어어문교육 Vol.7 No.1

This paper is to suggest the way to improve EFL reading skill through semantic mapping by leveled group activities. Semantic mapping is a categorical structuring of information in graphic forms or diagrams. It can be used to activate and organize background knowledge on topics in classrooms. For small group activities, the class is divided into higher leveled groups and lower leveled groups of four members based on their grades. The teaching process has three stages: Pre-reading, while-reading, and post-reading. In the pre-reading stage, students discuss what they know about the topic. They map ideas with a brainstorming technique. In the while-reading stage, they read the text about the topic. While they ar reading, they could ask some questions they might have and discuss the information in the text and categorize them with semantic mapping. In the post-reading stage, they discuss what they thought of the topic and add some information about the topic with semantic mapping. For the subjects of this study, third grade, middle school students were selected: 41 students for the experimental group and 35 students for the control group. The experimental period covered almost one semester from March to August, 2000. The results were as follows: 1) The students in the experimental group had higher scores in reading comprehension than those in the control group when semantic mapping was used; 2) The use of semantic mapping in reading comprehension was found to be much more effective in the higher leveled group than in the lower leveled group; 3) The results of questionnaires showed that many students became more interested and motivated in English, and semantic mapping helped them to participate positively in reading the English text. Thus, using semantic mapping by leveled group activities can be an effective alternative to traditional teaching methods for teachers who desire to improve reading skill in middle school students' English classes.
