연구목적: 최근 수년사이 인터넷 이용인구의 폭발적인 증가와 더불어 인터넷의 문제적 사용과 연관된 개인의 기능영역, 가정생활, 사회적 영역에서의 문제가 점차 증대되고 있다. 이에 인터넷 사용에 영향을 미칠 수 있는 다음의 세가지 요인, 즉 인터넷 사용 장소 (환경적 요인), 개인의 스트레스와 대처양식(개인적 요인), 가족의 분위기와 부모양육태도(가정 요인)가 문제적 인터넷 사용에 미치는 영향을 평가하고 이를 통하여 적절한 치료적 개입을 찾고자 하였다. 대상 및 방법: 남녀 고등학생 795명을 대상으로 먼저 인터넷 사용장소에 따른 인터넷 사용실태 설문조사를 시행하여 사용 장소에 따라 인터넷의 문제적 사용의 정도 및 성향의 차이를 비교 분석하였다. 두번째로 Young의 인터넷 중독척도를 사용하여 대상군을 중독 군과 비중독군으로 구분한 뒤 스트레스 척도, 대처양식 척도, 가정환경척도 중 관계영역척도, 부모양육행동척도를 실시하여 이러한 변인들이 인터넷 중독에 미치는 영향을 평가하였다. 결 과: 집에서 인터넷을 사용하는 군이 PC방을 이용하는 군보다 유의하게 높은 중독점수를 보였으며 인터넷을 시작한 시기는 더 늦은데 반해서 사용빈도나 사용시간이 유의하게 더 높았고 사용조절에서도 더 많은 어려움을 보였다. 중독수준에 따른 각 요인들의 비교분석결과 중독군 남학생에서 스트레스 점수가 유의하게 높았으며 대처양식에서 중독군이 비중독군에 비해 행동적극적 대처와 회피적 대처가 유의하게 높았다. 가정환경척도에서 중독군의 가족간 결합력, 표현력점수는 유의하게 낮고 갈등점수는 유의하게 높았으며 부모양육행동에서 중독군이 아버지의 합리적 설명과 애정은 적고, 부모 모두의 비일관성, 과잉기대, 과잉간섭, 학대와 방치하는 양육행동이 유의하게 더 높았다. 결 론: 본 연구 결과 PC방보다는 집에서 인터넷을 사용하는 청소년들이 인터넷의 문제적 사용으로 이행될 수 있는 빈도나 사용행태 에서의 문제점들이 더 많이 드러나는 바 부모들의 적절한 감독과 관심이 요구되며 중독군에서 일상에서 지각되는 개인의 스트 레스는 높으나 대처양식에서는 부정적, 회피적 전략을 많이 사용하며 가정환경이나 부모양육태도에서도 부정적이고 비지지적 환경을 일관되게 보고하고 있음을 볼 수 있다. 그러므로 청소년의 문제적 인터넷 사용 자체를 문제시하고 금지하기 이전에 개인의 스트레스 요인을 살피고 부모, 가족이 지지적 환경을 제공하도록 돕는 것이 인터넷 사용상의 문제에 대한 포괄적이고 일차예방적 효과를 가질 것으로 기대된다. Objectives:This study was intended to investigate the influences of the place for internet use, perceived stress, copying style, family support, parenting behavior on maladaptation in the adolescents with problematic internet use. Methods:The subjects of this study were 795 high school students in Incheon. They completed self-report questionnaires containing Questionnaires designed by authors, Young’s Internet Addiction Scales, Scales for the Perceived Stress, Copying Style, relationship sub-scales of Family Environment Scale and Parenting Behavior Inventory. Results: 1) Compared with the PC bang users, personal computer users at home had significantly higher mean addiction scores, spent more time for internet use, and had more difficulty with self-control. 2) Addictors, especially male addictors had significantly higher stress scores than non-addictors. 3) Addictors had significantly higher behavioral coping scores and avoidant coping scores than non-addictors. 4) Addictors had significantly higher family conflict scores, lower family cohessiveness scores and lower family expression scores than non-addictors. 5) Addictors experienced significantly less affection and reasoning from their father than non addictors. In addition, addictiors perceived significantly more physical abuse, intrusiveness, over-expectation, neglect, inconstancy from both parents than non addictors. Conclusion:Compared with the PC bang users, personal computer user had higher risk for problematic internet use. So they need more parent monitoring and help. Addictors had more daily stress, but used avoidant strategy to cope their stress and experienced less supportive family environment and negative parenting behavior than non-addictors. We recommend that parents pay attention to their adolescent’s stress factors and make effort to give the supportive environment and positive parenting behaviors.

The purpose of this study was to evaluate the fracture strength of class Ⅱ restored premolars with amalgam, posterior composite, amalgam-Ketac silver, resin-Ketac silver restorations at marginal ridge. Fifty extacted maxillary and mandibular premolar teeth that were caries free, fracture free, and restoration free were selected and randomly divided into five groups : Group 1:10 intact teeth, Group 2:10 teeth with class Ⅱ cavities and restored with, amalgam, Group 3:10 teeth with class Ⅱ cavities and restored with posterior resin, Group 4:10 teeth with class Ⅱ cavities and restored with amalgam-ketac silver, Group 5:10 teeth with class Ⅱ cavities and restored with resin-Katac silver. All teeth were mounted in base of dental stone within metal rings of 2cm diameter, exposing only the crown portion. Class Ⅱ mesio-occlusal or disto-occlusal cavities were prepared into specimens of Group 2 throung 5 by using a No. 710 fissure bur. The occlusal portion was prepared to a faciolingual width of 1.5mm and a pulpal depth of 1.5mm. The proximal protion was prepared to a faciolingual width of 4mm, a occlusogingival height of 4mm, and a gingival floor of 1.5mm. The teeth in Group 2 and 3 were resotored with silver amalgam and posterior resin respectively. In Group 4 and 5, proximal portions were first filled with Ketac silver 1.5mm gingivally and remaining cavities were restored with amalgam and posterior resin respectively. All specimens were stored in 100% relative humidity at 37℃ for 48 hours before testing. All teeth were subjected to a compressive load in a Universal Instron Testing Machine at marginal ridges. The loads required to fracture the restorations were recorded in killograms and the data obtained were subjected to statisticall analysis. The results were all follow: 1. The fracture strength of Group 1 which were unprepared were 100±10.0 kg and the higher values than Group 2, 3, 4, 5 which were prepared and resotred. 2. In restored groups, Group 2 had the higher fracture strength(81.8±12.4 kg) than other groups and Group 4 had the lowest fracture strength(66.8±9.2kg). 3. There were significant differences between fracture strength of between Group 1 and Group 3, 4, 5(P<0.05), but not significant difference between fracture strength of Group 2, 3, 4, 5(P>0.05).

Background and Objectives : Chronic suppurative otitis media is one of the frequent diseases in otolaryngologic field. It is important to choose of antibiotics in the management of infectious disease. But the organisms in infections have been changed and resistance to antibiotics has been grown as the development of antibiotics has been achieved. And so it has been necessary to recognize the changes of organisms and resistance in antibiotics. Our study was performed to identify the pathogens isolated from discharges in chronic otitis media and evaluate the antibiotic agents, to recognize the change of to resistance to·antibiotic agents and to use the appropriate anitiotics. Materials and Methods : Retrospectively, authors reviewed the backeriologic study of 114 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Soonchunhyang University in Seoul from Nov. 1996 to Oct. 1999 and analyzed 101 strains and its sensitivity test to various antibiotics. Result : In 93 cases in which pathogenic organism was isolated, single infection was 85 cases(91.4%) and mixed infection was 8 cases(8.6%). The most frequent pathogenic organism was Staphylococcus aureus(59.4%), Pseudomonas aeruginosa(13.9%), Providencia(4.8%), Alcaligenes(3.0%) and Streptococcus pneumoniae(2.9%) were the next. Methicilline-Resistance Staphylococcus aureus was 34 cases(57.6%) of Staphylococcus aureus. Staphylococcus aureus was sensitive to Vancomycin(96.7%), Trimethoprim-Sulfamethoxazole (57.6%), Cefuroxime(42.4%) and Ciprofloxacin(40.7%) but resistant to Penicillin(94.9%). Pseudomonas aeruginosa was sentitive Amikacin(100%), Ciprofloxacin(100%) and Gentamicin(67%). Conclusion : As MRSA recently was wide spread in community accquired infection as well as nosocomial infection, we must consider strict control of MRSA.

연구목적 : 본 연구는 범법행위로 인해 검참에 구속된 청소년들의 6개월 이내 재범여부를 예측할 수 있는 요인을 분석함으로써 재범의 가능성이 높은 청소년들을 조기에 선별하여 적절한 중재를 시행하기 위한 목적으로 시행되었다. 방 법 : 검찰에 구속된 후 교도소나 소년원에 수감되지 않고 석박된 남자 청소년 125명을 대상으로 하였다. 범죄기록 검토를 통해 사회인구학적, 범죄관련 변인들에 대해 조사하였고, 가족환경 및 부모양육태도, 정신병리, 성격장애, 도덕발달수준 등과 연관된 변인을 알아보기 위해, 부모-이동 갈등해결척도(CTSPC), 한국판 가정환경척도(FES), 한국형 부모양육행동척도, 간이정신진단검사(SCL-90-R), Beck 우울증척도, Beck 불안 척도, 한국판 청소년용 도덕발달수준 평가도구와 한국판 성격장애검사(PDQ-R)를 시행하였다. 결 과 : 전체 연구대상 125명 중 55명 (44%)이 석방 후 6개월 이내에 1회 이상의 재범을 행하였다. 재범군은 비재범군에 비해 구속당시 나이가 어리고, 신체적 학대력이 높았으며, 도덕발달수준이 낮고, SCL-90-R의 적대감척도점수가 높으며 PDQ-R의 반사회적 인격장애에 해당되는 경우가 많았다. 두 집단간 가족환경이나 부모양육태도에는 유의한 차이가 나타나지 않았다. 재범군은 폭력범죄로 구속된 경우가 비재범군에 비해 적었고 첫 범죄시 연령이 어리고 전과가 있는 경우가 많았다. 로지스틱 회귀분석 결과, 재범에 대한 예측요인으로 첫 범죄당시 연령(오즈비=2.91), 반사회적 성격장애(오즈비=2.85), 신체적 학대력(오즈비=2.65)의 세 변인이 포함되었으며, 재범여부에 대한 판별력은 72.8%로 나타났다. 결 론 : 본 연구결과 구속된 청소년들의 재범률이 매우 높다는 사실과 범죄행위에 가담한 연령이 어릴수록, 반사회적 성격장애가 있고 성장과정 중 부모로부터 학대를 받은 경험이 있을수록 반복적인 범죄를 저지를 위험도가 높다는 것을 알 수 있었다. 향후 비행 청소년들의 재범을 예방하기 위해서는 이러한 특성을 가진 고위험군에 대한 조기개입 및 적응을 돕기 위한 프로그램의 개발이 중요할 것으로 사료된다. Objectives : This study was performed to investigate the factors predicting recidivism within 6months after release in arrested juvenile delinquents for proper screening and intervention of high-risk-subjects. Methods : The subjects consisted of 125 arrested male adolescents who were released after legal procedure in prosecutor office and court. The socio-demographic and crime-related characteristics. Were evaluated by police records, and the familial, psychopathology and personality characteristics, and the level of moral development measured by the Conflict Tactics Scale(CTS), Family Environment Scale(FES), Parental Behavioral Inventory, Symptom Checklist-90-Revised(SCL-90-R), Beck Depression Inventory, Beck Anxiety Inventory, Korean form of Moral Developmental Inventory for adolescents, and Personality Disorder Questionnaire-Revised(PDQ-R). Results : The recidivism rate within 6 months after release was 44% of the initial sample, Recidivists were younger and had higher scores on Anger-hostility scale of SCL-90-R and lower principle morality score than nonrecidivists. More recidivists had history of physical abuse and antisocial personality disorder on PDQ-R than nonrecidivists. They also showed the crime-related characteristics of lower percent of violence crime, higher incidence of previous conviction, younger age of the first crime. Among those variables, logistic regression showed that age of first crime, antisocial personality disorder, and history of physical abuse best predicted the recidivism within 6months after release. Conclusion : These results of present study suggest that the recidivism rate of arrested male adolescents is very high, and the age of first crime, antisocial personality disorder and history of physical abuse were key factors predicting recidivism. To prevent repeated crime of delinquent adolescents, the development of programs for those high-risk groups to help rehabilitation and adaptation in community would be essentil.

The nucleophilic substitution reactions of cyclopentylarenesulfonates and cyclohexylarenesulfonates with anilines in acetonitrile at 65.0℃ are investigated. The cross-interaction constants ρxz(and βxz) between substitue-nts in the nucleophile(X) and leaving group(Z) are positive and have relatively small mmagnitude. The transition state(TS) variation is consistent with that predicted by the More O'Ferrall-Jencks diagram as expected from the positive ρxz. The small magnitude of ρxz correctly refrects a relatively loose TS structure in contrast to the tight TS for primary alkyl derivatives under similar reaction conditions.

Two men were admitted to hospital with flank pain, hematuria, which was diagnosised as ureteral stone. Elevation of aspartate aminotransferase (AST) without typical pattern of toxic hepatitis was observed. Careful history taking, several laboratory tests, abdominal and pelvis computered tomography was done. Findings from theses examinations supported the clinical diagnosis of ureteral stone complicated of exercised induced rabdomyolysis. Early recognization of rhabdomyolysis in clinical setting is important, because clinical manifestations have ranged from asymtomatic elevation of creatine kinase to acute renal failure which is a life threating medical emergency. Authors report two cases of exercised induced rhabdomyolysis initially admittied as ureteral stone managed with hydration

The purpose of this study was to inquire into the affected shoulder joint and the coxa of muscle strength and articular moving range of persons with cerebral apoplexy hemiplegia in aqua-rehabilitation program. The performance period of an experimental group was 12 weeks, 3 times per weeks and one time is 60minutes. In order to obtain the desired results, we measured the affected shoulder joint and coxa of muscle strength and articular moving range and an ex post test did again after 12 weeks. We used SPSS 10.0 for handling data and calculated mean and standard deviation about all changing factors. The differences before and after performance in each group was gauged by dependent t-test and the differences between each group was by independent t-test. The significance of all difference is p< 0.05. The conclusion were as follows: First, in change of muscle strength, there was significant different in only the shoulder joint flexor of an experimental group (p=0.037). Second, in change of articular moving range, there was significant different in only the shoulder joint flexure of an experimental group (p=0.047). Third, in change of muscle strength between each group, there was significant different in the shoulder joint flexor (p=0.04), the coxa flexure( p=0.046). Forth, in change of articular moving range between each group, there was significant different in only the shoulder joint flexure (p=0.046). Aqua-rehabilitation is a great help to a cerebral apoplexy hemiplegia case, but there is much to be desired in our country. We think that more scientific researches are needed.

연구배경 및 방법: 골형성부전증은 비교적 희귀한 유전병으로 교원질 대사 장애로 인한 골의 취약성과 다발성 골절 및 척추측만증 등을 특징으로 한다. 유전방식과 표현형의 발현 정도에 따라 다양한 임상 양상을 보이며, 임상적 중증도에 따라 4가지 형태로 분류된다. 지금까지 국내 보고는 분만과정이나 태아 진찰시 골격이상으로 발견된 증례보고가 주였다. 저자들은 비교적 경미한 임상 양상을 보이는 예를 포함한 다수의 골형성부전증 환자들의 전반적인 임상적 특징에 대해 보고하는 바이다. 결과: 2001년 6월부터 2003년 2월까지 골형성부전증으로 진단받은 6 가계, 10예를 대상으로 하였다. 평균 나이는 27.3(5∼56)세였고 소아가 2예였다. 모두 상염색체 우성으로 유전되었으며, 제 I형이 4예, 제 III형이 4예, 그리고 제 IV형이 2예였다. 전 예에서 다수의 골절 경험이 있었고, 골밀도 저하와 골피질 두께 감소 소견이 관찰되었다. 전신의 평균 골밀도는 0.690(0.421∼1.039) g/cm²였다. 골형성지표로 측정된 sAlk는 소아의 경우만 증가되어 있었고, 골흡수지표로 측정된 uDPD의 평균치는 12.9(4.4∼36.3) nM/mM Cr으로 증가된 소견을 보였다. mobility score는 대부분 3,4단계에 속해 있었다. 중증형일수록 진단 시의 mobility score가 낮은 경향을 보였다. 결론: 한국인 골형성부전증 환자의 임상적 특징을 살펴본 결과 기존의 보고된 II형 외에도 I, III, IV형이 다양하게 존재함을 알 수 있었으며, 모든 예에서 상염색체 우성으로 유전됨을 확인할 수 있었다. 또한 모든 예에서 증가된 골흡수로 인한 골밀도 저하와 골절을 확인할 수 있었다. Osteogenesis Imperfecta (OI) is a relatively rare hereditary disease, which is characterized by multiple bone fractures and spine scoliosis, due to the fragility of bone, and is often associated with blue sclerae, deafness and dentinogenesis imperfecta. Four types of OI can be distinguished, according to the clinical findings. Although mutations affecting type I collagen are responsible for the disease in most patients, the mechanism by which the genetic defects cause abnormal bone development remains to be fully understood. Here, the clinical characteristics of 10 OI patient cases are reported, with a review of the literature. All the cases, including 4 type I, 4 type III and 2 type IV, inherited OI as an autosomal dominant trait. All the subjects had multiple old fractures and decreased bone densities. In this study, the biochemical marker of bone formation, serum alkaline phosphatase, was found to be increased only in the pediatric OI patients, while the biochemical marker of bone resorption, urinary deoxypyridinoline, was increased in all cases. The mobility score was found to correlate with the severity of the type on diagnosis (J Kor Soc Endocrinol 18:496∼503, 2003).
