In oral maxilofacial surgery, limited mouth opening (trismus) is a common symptom resulting from traumatic and postoperative conditions involving the muscles of mastication and their attachments. The limited mandibular function of trismus can result in impaired nutrition, speech, oral hygiene and lifestyle. In the head and neck cancer patient, these symptoms can occur at a time when nutrition, attitude and oral hygiene can be very important to comfort and recovery. Limited jaw mobility can make it difficult to introduce food into the mouth and interferes with the oral preparatory phase of swallowing. Therefore we have to treat the limited mouth opening with various method such as hot pack, muscle massage, muscle stretch with manual, tongue blade and therabite jaw motion rehabilitation system. This study has demonstrated the efficacy of therabite jaw motion rehabilitation for treatment of limited mouth opening in mandibular fracture, internal derangement of TMJ, deep facial infection patients. Ten patients complaining of limited mouth opening were treated by therabite jaw motion rehabilitation system. This treatment was found to be effective in reestablishing normal mouth opening within 4 week in postoperative. It is suggested that therabite jaw motion rehabilitation system is simple, non-invasive, inexpensive, and highly efficient procedure in patients with limited mouth opening.

Unilateral pulmonary vein atresia is a rare congenital disease and is frequently associated with intracardiac anomalies. It is usually diagnosed in childhood and is very rarely diagnosed in adulthood. A case of unilateral pulmonary vein atresia in a 20-year old female is de- scribed. The relevant findings were symptoms of exertional dyspnea, roentgenographic evidence of decreased lung volume, increased interstitial infiltration with septal lines in the involved side (right), and aoscence of blood flow in a radionuclide perfusion scan. Pulmonary angiography showed an extremely small right pulmonary artery and thining of the peripheral branches, and nonvisualization of the draining pulmonary veins. Bronchial arteriography showed rommunication between the bronchial artery and the right pulmonary artery and it was drained to the left pulmonary artery. Cardiac catheterization showed no intracardiac anomaly. The right bronchography was normal; pulmonary function studies showed a pure restrictive pattern and markedly in creased physiologic dead space. MRI showed no visible right pulmonary vein.

탁수연,박영신,김의철 한국아동교육학회 2005 아동교육 Vol.14 No.1

본 연구는 보호관찰청소년들의 특성을 심층적으로 접근하기 위하여 상담을 통한 사례분석을 시도하였다. 분석대상은 인천광역시에서 보호관찰을 받으면서 상담실에 의뢰된 청소년 중 50명(남: 38명, 여: 12명)을 대상으로 하였다. 이 중 상담이 계속 진행 중이거나 보호관찰 교육이 종료된 상담지속집단 26명(남: 19명, 여. 7명)과, 재범을 일으켜 상담이 중단된 상담중단집단 24명(남: 19명, 여: 5명)을 집단 구분하여 환경과 심리행동의 차이를 살펴보았다. 또한 2002년 1월부터 1년 동안 상담한 3명의 사례를 제시하였다. 첫 번째 사례는 폭력으로 재범을 하여 상담이 중단된 고등학교 1학년에 복학한 남자 청소년의 경우이고, 두 번째 사례는 부모의 관심과 도움으로 성공적으로 보호관찰을 마친 중학교 2학년 여자 청소년의 경우이며, 끝으로 집나간 어머니와 교도소에 간 아버지를 기다리며 오갈 데 없이 떠돌아다니다 연락이 두절되어 상담이 중단된 14세의 남자 청소년의 사례를 제시하였다. 상담 중인 보호관찰 청소년의 집단별 차이를 분석한 연구 결과, 상담 지속 집단과 상담 중단 집단간에 가정환경과 심리적 특성의 모든 변인에서 차이가 없는 것으로 나타났다. 양적인 분석과 더불어 상담활동을 통한 사례분석은 보호관찰 청소년의 심리 특성에 대해 보다 심층적으로 이해하고 본질적인 원인을 찾아내어 재범 방지와 청소년 지도에 기여할 수 있는 자료가 될 것이라는 점에 본 연구의 의의를 둔다. This paper attempted a case study through counseling to analyze the characteristics of adolescents under probation. A total of 50 adolescents under probation(male 38, female 12) in Incheon that were in the process of counseling participated in this study. This examines the environmental and psychological differences between 24 respondents that recommit crimes and discontinued counseling and 26 respondents that were in the process of counseling. And we represented three case of counseling for one year from 2002. The first case is a male, first year high school student who recommit violation while he was under probation. The second case is a female, second year middle school student who successfully finished probation period without recommitment of crime, thanks to her parents' care and help. The third case is 14 year old boy who is under a criminal trial, whose father is in jail, and mother left the family. With the results, there was no family environmental and psychological characteristic difference between continuous counseling group and discontinuous counseling group. A case of study through counseling and quantitative analysis provide data that we understand adolescents' psychological characteristics and reduce recurrence of juvenile delinquency.

탁수연,김의철,박영신 한국아동교육학회 2004 아동교육 Vol.13 No.2

토착심리학적인 접근방법에 의해 한국인의 성공외식과 실패의식에 관한 연구가 이미 진행되어 왔다. 본 연구는 TMF시대 전후의 미래성찰에 대한 한국인의 사회적 표상을 분석하는데 주된 목적이 있다. 이를 위한 구체적인 분석 내용은, 한국 사람들이 미래에 하고 싶은 일, 미래성치에 도움이 필요한 사람, 미래성과에 가장 중요한 요인을 시도하였다. 즉, 한국인의 미래 성취의식에 대한 분석은 학생과 성인 세대별로 시도하고, IMF시대 전후 비교를 통하여 이러한 결과를 단편적으로 이해하는 것이 아니라 종합적인 관계 속에서 파악하고자 한다. 130 이전 연구의 분석대상은 학생은 고등학생 486명(남273, 여 209, 무용담 4)과 대학생 244명(남 113, 여 127, 무응답 4)으로 총 730명 이었다. IMF시대 이후의 표집대상은 총 988명으로서 학생 481명(초 116명, 중 88명, 고 72명,대 205명), 성인 507명(부 236명, 모 271명)이었다. IMF시대 전후의 미래성취의 분석결과는 동일하게 나타났다. 미래에 하고 싶은 일로 학생은 취업과 학업성취를, 성인은 가정생활과 직장생활에 가장 많은 반응을 보였다. 미래성취에 가장 도움이 필요.한 사람으로는 학생은 부모님을 성인 집단은 배우자를 포함한 '부모 의 가족'을 지적하였다. 미래 성취에 가장 중요한 요인은 꾸준한 노력과 강인한 의지력 같은 '자기조절'이 가장 높은 반응을 보였다. Past researches have examined the indigenous characteristics of achievement and failure experiences prior to the 1997 Asian Economic Crisis, otherwise known as the IMF crisis in Korea. The purpose of this study is to examine achievement aspiration of respondents before and after the economic crisis. Respondents were asked what they would like to achieve in the future, the significant other from whom they needed to receive social support, and the main factor that will help them to achieve their goal. A total of 730 participants, consisting of 486 high school students (273 male, 209 female, and 4 no response) and 244 university students (113 male, 127 female, and 4 no response) completed an open-ended survey prior to the economic crisis. A total of 988 Korean students and their parents participated in the study after the economic crisis (116 primary school students, 88 middle school students, 72 high school students, and their fathers 236 and mothers 271). The overall pattern of results before the economic crisis is similar to those obtained after the economic crisis. For students, the most aspired future achievements are obtaining a desire profession and academic achievement. For adults, happiness within the family and job success are the most important future achievements. For social support, students indicated that they needed support from their parents, and adults indicated that they needed support from their spouse and other family members. Both groups indicated that self-regulation (i.e., persistence effort and will) as the most important factor for them to realize their goals.

Low Level Control of Metal Belt CVT Considering Shift Dynamics and Ratio Valve On-Off Characteristics

Kim, Tal-Chol,Kim, Hyun-Soo The Korean Society of Mechanical Engineers 2000 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.14 No.6

In this paper, low level control algorithms of a metal belt CVT are suggested. A feedforward PID control algorithm is adopted for line pressure based on a steady state relationship between the input duty and the line pressure. Experimental results show that feedforward PID control of the line pressure guarantees a fast response while reducing the pressure undershoot which may result in belt slip. For ratio control, a fuzzy logic is suggested by considering the CVT shift dynamics and on-off characteristics of the ratio control valve. It is found from experimental results that a desired speed ratio can be achieved at steady state in spite of the fluctuating primary pressure. It is expected that the low level control algorithms for the line pressure and speed ratio suggested in this study can be implemented in a prototype CVT.

김호중,김영식,김선만,김상철,김주현,이부수 대한응급의학회 2002 대한응급의학회지 Vol.13 No.4

Purpose: This study assessed the results of the cardiopulmonary-cerebral resuscitation (CPCR) performed by advanced cardiovascular life support (ACLS) teams on cardiac-arrest patients in pundang - jeseang general hospital by using the in hospital Utstein style. Methods: From march 1999 to February 2001, we collected data based on a formatted protocol by using the in hospital utstein style. The subjects were adult patients over the age of 20 years who had not experienced trauma and who had been resusciated in the hospital (the emergency department (ED), the ward, and intensive care unit, etc.) by an ACLS team. We studied three groups: group Ⅰ (ED), group Ⅱ (general ward), and group Ⅲ (ICU). Results: among 100,552 patients who were admitted, we resuscitated 152 patients (23 in group Ⅰ, 83 group Ⅱ, 46 group Ⅲ). The number of male patient was higher than the number of female (78%/22%, 57%/43% & 53%/47%). For group Ⅰ, Ⅱ, and Ⅲ, respectively patients between 50 and 70 years of age were predominant, and in all groups, the most witness of the cardiac arrest was the nurse. Performed CPCR methods were complex (87%, 80% & 100%), compression only (4%, 0%, 0%), defibrillation only (9%, 17% & 0%) and ventilation only (0%, 3% & 0%). Initial EKG rhythms were VT/VF (9pts 39%, 44pts 53% & 22pts 48%), PEA (9pts 39%, 23pts 28% & 19pts41%) and asystol (5pts 22%, 16pts 19% & 5pts 11%). The average intervals (minutes) from arrest to CPCR were 0.4±0.4, 3.1±2.2, 1.0±0.6, from arrest to initial defibrillation were 2.7±1.3, 4.0±3.2, 3.0±1.1, from arrest to intubation were 0.5±0.4, 3.8±1.3 & 1.1±1.0 and from arrest to initial epinephrine were 1.4±0.7, 3.0±4.4, 1.5±1.1 The durations of resuscitation minutes were 23.1±22.1, 29.6±13.8, 19.4±14.6 The rates of return of spontaneous circulation were 70% (16/23), 55% (46/83), 77% (34/46). The number of discharged patinets were 3 (13%), 8 (9.6%), 9 (45%). The number of patients alive after 1year were 2 (8.7%), 2 (3.4%), 7 (15.2%). Conclusion: The rate of return of spontaneous circulation (ROSC) and the number of patinets after 1 year were higher when the resuscitation was performed quickly, and the ACLS team played a great role in this result. Thus, the resuscitation education and training of nurses are very important and should be pursued continuously.

Integrated Engine-CVT Control Considering Powertrain Response Lag in Acceleration

Kim, Tal-Chol,Kim, Hyun-Soo The Korean Society of Mechanical Engineers 2000 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.14 No.7

In this paper, an engine-CVT integrated control algorithm is suggested by considering the inertia torque and the CVT ratio change response lag in acceleration. In order to compensate for drive torque time delay due to CVT response lag, two algorithms are presented: (1) an optimal engine torque compensation algorithm, and (2) an optimal engine speed compensation algorithm. Simulation results show that the optimal engine speed compensation algorithm gives better engine operation around the optimal operation point compared to the optimal torque compensation while showing nearly the same acceleration response. The performance of the proposed engine-CVT integrated control algorithms are compared with those of conventional CVT control, and It is found that optimal engine operation can be achieved by using integrated control during acceleration, and improved fuel economy can be expected while also satisfying the driver's demands.

The Prevalence Rate of Tuberculin Skin Test Positive by Contacts Group to Predict the Development of Active Tuberculosis After School Outbreaks

Kim, Hee Jin,Chun, Byung Chul,Kwon, AmyM,Lee, Gyeong-Ho,Ryu, Sungweon,Oh, Soo Yeon,Lee, Jin Beom,Yoo, Se Hwa,Kim, Eui Sook,Kim, Je Hyeong,Shin, Chol,Lee, Seung Heon The Korean Academy of Tuberculosis and Respiratory 2015 Tuberculosis and Respiratory Diseases Vol.78 No.4

Background: The tuberculin skin test (TST) is the standard tool to diagnose latent tuberculosis infection (LTBI) in mass screening. The aim of this study is to find an optimal cut-off point of the TST+ rate within tuberculosis (TB) contacts to predict the active TB development among adolescents in school TB outbreaks. Methods: The Korean National Health Insurance Review and Assessment database was used to identify active TB development in relation to the initial TST (cut-off, 10 mm). The 7,475 contacts in 89 schools were divided into two groups: Incident TB group (43 schools) and no incident TB group (46 schools). LTBI treatment was initiated in 607 of the 1,761 TST+ contacts. The association with active TB progression was examined at different cut-off points of the TST+ rate. Results: The mean duration of follow-up was $3.9{\pm}0.9years$. Thirty-three contacts developed active TB during the 4,504 person-years among the TST+ contacts without LTBI treatment (n=1,154). The average TST+ rate for the incident TB group (n=43) and no incident TB group (n=46) were 31.0% and 15.5%, respectively. The TST+ rate per group was related with TB progression (odds ratio [OR], 1.025; 95% confidence interval [CI], 1.001-1.050; p=0.037). Based on the TST+ rate per group, active TB was best predicted at TST+ ${\geq}$ 16% (OR, 3.11; 95% CI, 1.29-7.51; area under curve, 0.64). Conclusion: Sixteen percent of the TST+ rate per group within the same grade students can be suggested as an optimal cut-off to predict active TB development in middle and high schools TB outbreaks.
