Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

The aim of this study was to evaluate the effect of various polymerization techniques on the microleakage of compomer restorations. Fifty extracted human premolar and molar were used and randomly divided into 5 groups. After cavity preparation, compomer (F2000) was filled according to the manufacturer's directions. All groups, except group 5, were filled using an incremental technique. Group 1was polymerized for 40 seconds at a continuous 485mW/㎠ with a VIP (Bisco, USA) light cure unit. Group 2 was polymerized for 20 seconds at a continuous 345mW/㎠ and then for 20 seconds at 645mW/㎠ with the VIP light cure unit. Group 3 was polymerized at 400mW/㎠, gradually increased to 50mW/㎠ per 10 seconds until 550mW/㎠ was reached; total 40 seconds with a Spectrum 800 (Dentsply Caulk, USA) light cure unit. Group 4 was polymerized for for 3 seconds using an incremental technique with a Flipo (LOKKi, France) light cure unit. Group 5 was polymerized for 3 seconds using a bulk fill technique with the Flipo light cure unit. The specimens were embedded with acrylic resin, and were sectioned with diamond saws in a mesiodistal direction along the longitudinal axis of the tooth so as to pass through the center of the restoration, and three surfaces (occlusal, pulpal, and gingival) were examined with SEM. The results were as follows; 1. Group 5 showed a significantly larger gaps compared to other groups on the gingival, occlusal, and pulpal walls. 2. All groups except group 5 had no statistically significant gap on the gingival, occlusal, and pulpal walls. 3. There was no significant correlation between the amount of enamel on the gingival and occlusal walls and polymerization shrinkage.

The purpose of this study was to understand the emotions of parents with children undergoing operation, and find effective nursing inter- vention method. The subjects of study were 19 parents whose children were undergoing operations in a university affiliated hospital in Seoul. The parents were alert enough to be interviewed and agreed willingly to participate in this study. Data was gathered from June to July 1996 through an in-depth interview of the parents open and unstructured questions. The author interviewed each parent before the operation, during the operation, and after the operation. The interview were 15 minutes to 40 minutes long. The Content of the interviews was recorded and transcribed later. Transcription took between 2 to 4 hours. The data was analyzed using Giorgi's phenomenological analysis method. Similar data was grouped into higher categories and named. The results were as follows. 1) The category of experience of the parent before the child's operation was classified into 7 groups such as : anxiety, overwhelming by burden, transcendental attitude, expectation, desire for escape, dissatisfaction and satisfaction. 2) The category of the experience of the parent during operation has shown 6 types as shown below : anxiety, overwhelming by burden, expectation, desire to get together, dissatisfaction and satisfaction. 3) The category of the experience of the parent after the child's operation has shown 5 types : anxiety, overwhelming by burden, expectation, dissatisfaction and satisfaction. The parents who were anticipating the operation of their child experienced anxiety and were very sorry that the child would go through the operation. On the other hand, they hope for a good result of the operation as a result of the doctor's effort. They especially rely on and thank God when they are religious. Parents whose children will have an operation often experience panic before their kid's operation and are concerned about their kids, but they have hope for a good operation and faith in the medical team. When the parents have religion, they have faith that god will take care of their child. When the parents are optimistic, religious, have much faith in the medical team, perceive that the disease is not more serious than others, or have experience with their own operation, they tend not to worry to much. The parents of the patient were also concerned about anesthesia, operation, pain, complication and the effect on the rest of the family members who were at home. They were dissatisfied with the unkind manner of the hospital staff and insufficient explanation by the doctor, but satisfied with the kindness of the medical team. They were nervous about their kids operation, expected good results and nice treatment from a medical team, and hoped that their kids would get well. They regreted that they could not be with their children during the operation and hoped to be with kids soon after ward. They hurt their mind thinking of their patients. Waiting too much time for the operation, not enough explanation about the operation and the medical staff not considering the patient's needs made the parents dissatisfied. They were relieved with good result of the patients who were worse case than their children. The good manner of the staff made the parents feel appreciated. They were relived after the operation was finished without trouble, and thought that the operation was successful. They changed their understanding of health. They also thankful to God for the good operation and to the medical team who shown good manner. And they experienced the uneasiness of a recovery and a sequelae and depended on god that everything will be fine. They felt sorry for their kid's pain after operation. They often said that, the hard part after operation was that they felt sorry for their kid's pain. According to this research, I would like to suggest the intervention for the patients with child after/before operation. 1) Hope the result of this research will influence how nurses treat the parents of pediatric surgical patient in the future. 2) This research dose not consider the severity of the patient, so it needs to be considered.

조혜진,이경하,이세준,이광원 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.4

Compomer is composed of matrix and filler; matrix is made of the combination of resins and polycarboxylic molecules that are light-cured. and a filler is a glass component which is capable of ion-release. The resin content of compomers produces polymerization shrinkage which can adversely affect marginal adaptation. Pretreatment is a fundamental step which is treated with conditioner or primer in the use of these materials. Microleakage of restorative materials has been investigated mostly by dye penetration method. Dye penetration method was not quantitative and not measured repeatedly. Fluid filtration method. introduced and developed by Pashley's group, has been extensively used for 20 years for research purpose to understand the physiology of dentin, as well as the effects of various restorative treatments on dentin permeability. It permits quantitative, nondestructive measurment of microleakage in a longitudinal manner. The purpose of this study was to evaluate the change the change of dentin permeability according to the process of compomer restoration. In this study, CI Ⅴ cavities were prepared on buccal surface of thirty extracted human molars. The prepared cavities were etched by 37% phosphoric acid. The experimental teeth were randomly divided into three groups. Each group was treated with following materials; Group 1 : Prime & Bond NT/Dyract AP, Group 2: Single Bond/F2000 compomer, Group 3 : Syntac Single Component/Compoglass. The bonding agent and compomer were applied for each group following manufactures information. Dentin permeability of each group was measured at each process by fluid filtration method; Step 1 : preparation(smear layer), Step 2 : etching(smear layer removal), Step 3 : applying the bonding agent, Step 4 : filling the compomer. Dentin permeability was expressed by hydraulic conductance(㎕ min^-1cmH_2O^-1). The data were analysed statistically using One-way ANOVA and Sheffe's method. The results were as follows : 1. Dentin permeability differences between each process were significant except between step 1 and step 2(p<0.01). 2. Dentin permeability after removal of smear layer was highly increased(p<0.01). 3. In most case, decrease of dentin permeability was obtained by applying bonding agent(p<0.01). 4. Dentin permeability differences among the experimental groups were not significant(p>0.05). 5. None of compomers used in this study showed perfect seal at the interface.

The actual administrative conditions of the environment research institutes attached to the universities and colleges were investigated by means of the questionnaire to propose the reference data for the reasonable and effective management of them. The majority of them were established after 1981, and half of them are unregistered. The retention rates of the full-time researchers and the attendants was 55%, and that of the official facilities was high, but the equipments for analysis and measurement were poorly furnished as 15%. Annual mean amounts of the fund for management and research are less than ten million and more than thirty million won, respectively. Therefore their major roles are limited to consultations, supervising academic conferences, and collecting research materials because of the fund limitations. Half of them distribute their own publications, and subscribe for few scientific journals regularly. There are many obstracles in the management of institutes such as lack of funds, deficient administrative support of the college authorities, deficiencies of full-time researchers, attendants, and equipments for analysis and measurement.

본 연구는 Ⅱ급 부정교합자에서 액티베이터 사용 후, 하악골의 변화에 따른 atlas의 위치 및 형태 변화를 조사하고, 그에 따른 치료 효과를 예측해 보고자 시행하였다. 실험군으로 Ⅱ급 부정교합자로써 액티베이터 치료를 시행한 경우 1군(총30명, 남자 15, 여자 15명), 대조군들로 Ⅱ급 부정교합자로 액티베이터 치료를 받지 않고, 교정치료를 받은 2군(총 22명, 남자 12, 여자 10)과 Ⅰ급 부정교합자로 치료를 받은 환자 3군(총 22명, 남자 12, 여자 10)으로 총 세 개의 군으로 나누었다. 치료 전(T1), 액티베이터 사용 중지 및 치료 중간시기(T2), 치료 종료(T3)시의 측모두부방사선사진을 통해서 골격 형태 계측 및 atlas 형태 계측을 시행하였다. Ⅱ급 액티베이터 사용 결과 액티베이터를 사용하지 않은 Ⅱ급 부정교합자 군에 비해 치료 종료 시 다음과 같은 계측치 들에서 골격적인 효과가 나타났다: ramal height, body length와 effective body length는 증가하였고, ANB는 감소하였다. Overjet은 두 군 사이에서 액티베이터 사용 후 유의한 감소가 일어났으나, 치료 종료 시에는 유의한 변화가 없었다. 세 군 모두에서 FH에 대한 atlas의 시계방향 회전이 나타났으나, 실험군 1군에서 대조군 2, 3군에 비해 유의하게 atlas가 FH에 대해 시계방향 회전되는 결과가 나타났다. 1군이 3군에 비해서 atlas의 유의한 후방이동을 보인 것을 제외하고는 세 군 사이의 atlas의 전, 후방적 위치나, 형태의 크기 변화에 있어 유의한 차이점은 없었다. 위의 결과들을 고려해 볼 때 atlas의 장축의 시계방향 회전은 액티베이터의 사용 효과로 생각되며, 이는 차후 Ⅱ급 부정교합자에서 액티베이터 치료 효과를 판단하는 또 하나의 지표가 될 수 있다고 생각한다. Objective: Previous studies have reported that morphological features of the first cervical vertebra(atlas) have been associated with mandibular growth direction. The purpose of this study was to show the possible positional and morphological changes of the Atlas from activator treatment in Class Ⅱ malocclusion patients. Methods: Lateral cephalometric radiograph tracings were made at initial, middle and final stages of treatment. Angular and linear measurements of skeletal and morphological features were measured on the anatomical landmarks and reference planes. Results: The skeletal effects of activator treatment on Class Ⅱ malocclusion patients were evident on ramal height, body length, effective body length, ANB, and overjet. Clockwise rotation of the long axis of the Atlas was found in Group 1, but there was no inclination change of the Atlas in groups 2 and 3. There was no significant correlation between anterior and posterior positions of the atlas or morphological change in all groups. - except for posterior movements of the Atlas found in group 1. Conclusion: Clockwise rotation of the atlas axis resulted from activator treatment in CI Ⅱ malocclusion patients. Change in atlas axis can be thought of as an indicator for success of activator treatment.

누구를 위한 POCT인가?

조경진,이창규,이승관,정희천,김미숙,남경미,전주임 高麗大學校 倂設 保健大學 保健科學硏究所 2001 保健科學論集 Vol.27 No.2

Patient-oriented minds and Bill of Rights have brought a lot of POCTs or Waived Tests, which can obviously be threats to the medical technology profession. However, we cannot help but admit the realities and should take some necessary measures to meet the situation. Accordingly we took a survey to find what opinions medical scientists or nurses have against the POCTs. Most of the scientists worried about the reliabilites of test results while nurses were concerned about the ambiguity of their job entities. Taking account of the POCT nature, the scientists should lead the development of POCT menus and have the primanry responsibility to educate or train the POCT perfomers maitaining periodic QCs on all the procedures or equimpments, not paying much attention to the issues who might be the performers.
