This study was designed to establish working range for reoportable range in own laboratory in order to cover the upper and lower limits of the range in test method. We experimented ten times during 10 days for setting of reportable range with between run for method evaluation. It is generally assumed that the analytical method produces a linear response and that the test results between those upper and lower limits are then reportable. CLIA recommends that laboratories verify the reportable range of all moderate and high complexity tests. The Clinical Laboratory Improvement Amendments(CLIA) and Laboratory Accreditation Program of the Korean Society for Laboratory Medicine states reportable range is only required for "modified" moderately complex tests. Linearity requirements have been eliminated from the CLIA regulations and from others accreditation agencies, many inspectors continue to feel that linearity studies are a part of good lab practice and should be encouraged. It is important to assess the useful reportable range of a laboratory method, i.e., the lowest and highest test results that are reliable and can be reported. Manufacturers make claims for the reportable range of their methods by stating the upper and lower limits of the range. Instrument manufacturers state an operating range and a reportable range. The commercial linearity material can be used to verify this range, if it adequately covers the stated linear interval. CLIA requirements for quality control, must demonstrate that, prior to reporting patient test results, it can obtain the performance specifications for accuracy, precision, and reportable range of patient test results, comparable to those established by the manufacturer. If applicable, the laboratory must also verify the reportable range of patient test results. The reportable range of patient test results is the range of test result values over which the laboratory can establish or verify the accuracy of the instrument, kit or test system measurement response. We need to define the usable reportable range of the method so that the experiments can be properly planned and valid data can be collected. The reportable range is usually defined as the range where the analytical response of the method is linear with respect to the concentration of the analyte being measured. In conclusion, experimental results on reportable range using concentrated control sample and zero calibrators covering from highest to lowest range were salicylate $8.8{\mu}g/dL$, phenytoin $0.67{\mu}g/dL$, phenobarbital $1.53{\mu}g/dL$, primidone $0.16{\mu}g/dL$, theophylline $0.2{\mu}g/dL$, vancomycine $1.3{\mu}g/dL$, valproic acid $3.2{\mu}g/dL$, digitoxin 0.17ng/dL, carbamazepine $0.36{\mu}g/dL$ and acetaminophen $0.7{\mu}g/dL$ at minimum level and salicylate $969.9{\mu}g/dL$, phenytoin $38.1{\mu}g/dL$, phenobarbital $60.4{\mu}g/dL$, primidone $24.57{\mu}g/dL$, theophylline $39.2{\mu}g/dL$, vancomycine $83.65{\mu}g/dL$, valproic acid $147.96{\mu}g/dL$, digitoxin 5.04ng/dL, carbamazepine $19.76{\mu}g/dL$, acetaminophen $300.92{\mu}g/dL$ at maximum level.

Occupational health services in Korea have been operated as dual types : one is operated by occupational health care manager and the other is health care agency without their own personnel. The performance of occupational health service should be different due to the variety of characteristics of health care manager and workplace, qualification of health care manager. This study is to analyze performance of occupational health care services with a particular consideration of job performance shape and efficiency, based on comparing those two types of health care management to show on the basic data for the settlement of more qualitative health care management system at workplace. For this study, total 391 places in Seoul and Inchon city area ; 154 places (39.4%) managed by designated health care manager and 237 places (60.6%) by the agency with their commission are selected as research samples. Tools for data collection are questionnares that have been investigated during the period of 20 September 1993-20 December 1993. Those data are compared with percentiles, mean, standard deviation and B/C ratio using SPSS PC program. Conclusions observed from the tests and each comparison could be summerized as follows : 1. Occupational health care have been accomplished at workplaces with designated people than with agencies people, and coverage rate of the occupational health care services has differences, due to management types. The reason of these results is due to visit only one or two times monthly by the agencies, while their own health care manager obsess, at the workplaces all the times. 2. Most of the expense for environmental control of all health care services expenditures shows that there is almost no fundamental improvement because more expenses are needed for procuring personal protective equipment and measuring work environment instead of environmental improvement. 3. It is investigated how much the cost of occupational health care services needs per worker, and calculated how much the cost needs per service hour per worker. The results from this show that the cost of occupational health services at workplaces with their own managers used less than the cost of health care agencies, eventually the former gives better services with less cost than the latter. 4. Benefit/Cost ratio is also produced by total benefit/total cost. The result from the above way reads 4.57 as a whole, while their own manager having workplaces reads 4.82 and the agencies do l.56. Even if their own manager performing workplaces spent more cost, this system produces more benefit than the agencies management. 5. The B/C ratio for medical organization such as local clinic, health care center and pharmacy shows more than or equal to at the workplaces controlled by the agencies. It is inferred that benefit would be much less than the cost used, with so being inefficient. 6. It is assumed that the efficiency ratio of health education is equal to reduction rate of workers medical organization visit. Estimated reduction rate 5%, 10%, 15%, show that the efficiency ratio of health education have an effect on producing benefits. It is estimated that more benefit can be produced if more qualitative education will be provided for enhancing health care efficiency. 7. Results of this study cannot be generalized because there are large scale of deviation in case of workplaces with less than 300 full time workers, but B/C ratio reads 2.69 as a whole and 3.25 at workplaces with their own health care manager are higher than 1.63 at the workplaces manged by the agencies. Finally, all the benefit concerning health care services could not be quantified, measured and shown on the value of money. This is a reason that a considerable part of benefits are so underestimated. This is also thought that measurement tools should be developed for measuring benefits of health care services with a comprehensive quantification. in the future. It is also expected that efficiency of occupational health care services should be investigated using cost-effectiveness analysis.

The purpose of this study was to identify the degree of sexual adjustment and quality of life in married men with spinal cord injuries and to furnish primary data to sexuality rehabilitation nursing practice which can lead to ideal sexual life and quality of life those men with SCI. Seventy married men with SCI were conveniently sampled in Kwangju, Suncheon, Mokpo and Seoul for responding the questionnaire, which was based on this research. With the research scale, SIS (Sexual interest and satisfaction) by Siosteen et al.(1990) and SB(Sexual behaviour) by Kreuter et al.(1996) were used for the measurement of sexual adjustment. And, for measuring quality of life was used SCI QL-23(Spinal cord injury of life-23) scale by Lundqvist et al.(1997). Data were collected from January 20 to March 20, 1999, using a structured questionnaire. A hundred volumes of questionnaire were used. and 85 volumes were collected, 70 volumes were used as research data after excluding 15 volumes unsuitable to data analysis. The obtain data were analysed using percentage, t-test, ANOVA, Duncan test, and Pearson's correlation by SAS PC+ program. The results were as follows: 1. The mean score of sexual interest and satisfaction of the subjects was 8.42. out of 18. The ways of their sexual behavior after spinal cord injuries were embracing and caressing (62.9%), kissing(58.6%), caressing breast with hands (55.7%), caressing breast with hands (52.9%), caressing genitals with hands (37.2%), caressing genitals with mouth(30.0%) and sexual intercourse (18.6%). The mean score of quality of life was 52.53 out of 100. 2. Age(F=3.24, p=.045) and caregiver (F=4.02, p=.022)were major variables which reveals significant differences in terms for sexual interest and satisfaction. The later results on Duncan's test showed that subjects who were in their 30s or 40s were significant higher than subjects whose age were in their 50s in their sexual interest and satisfaction. Also subjects with their spouse's care or mother's care were higher than those with other's care. 3. Subjects with incomplete paraplegia were higher than those with the complete paraplegia in sexual interest and satisfaction (F=3.01, p=.036). 4. Variables that showed the significant differences in the quality of life were education(t=2.860, p=.007) and period of marriage(t=2.125, p=.037). and occupational status(t=-2.161, p=.034). High school graduates, those who married before spinal cord injuries and those who didn't have occupation were higher than the other subjects. 5. Variables that revealed significant differences in the quality of life were time passage after spinal cord injuries(F=8.72, p=.001) and injured level of spinal cord(F=3.32, p=.042). Duncan's test showed that subjects who had lived for less than 4 years were higher those with time passage of 5-9 years and 10 years. Also subjects with lumbar injuries were higher than those with thoracic injuries in terms of quality of life. 6. There was negatively correlated between sexual interest and satisfaction and quality of life(r=-.256, p<.05). As a result of these findings sexuality rehabilitation for individuals with SCI was very important issue for their quality of life. Thus, registered nurses who care clients with SCI should activily participate in the client's sexual needs. Also, various sexual behaviors as well as sexual intercourse should be encouraged for the sexual adjustment of client's with SCI.

세계이차대전을 계기로 전쟁으로 인한 난청의 피해는 물론이고 각방면의 산업이 급히 발달함으로서 소음에 대한 문제는 사회적 또는 법의학적인 면에서 여러가지 문제점을 제시하게 되었다. 소음이 인체에 미치는 영향은 크게 일반적인 피해와 청각적인 피해로 분류해서 생 각 할 수 있다. 일반적인 피해 많은 실험으로 수면장해, 불쾌감, 정서 등에 나쁜 영향을 주며 작업능률이 떨어진다는 점을 증명하였다. 생리기능에도 작용해서 Laird등은 50∼60 phone의 소음으로 타액, 위액의 분비가 감소되고 혈압상승, 맥박수의 증가, 말초혈관의 수축 등을 일으킨다고 보고하였다. 또한 내분비계에 작용해서 부신홀몬의 감소 gonado-tropine분비가 감소되고 갑상선자극 홀몬은 증가한다고 한다. 청각적인 피해 19세기경부터 소음때문에 청각장해를 일으킨다는 보고가 있고 그후 많은 학자들에 의하여 소음과 난청에 대한 연구보고가 있다. 1947년 Weiss는 이차대전때 청력을 잃은 수가 15만명 정도로 보고하였는 바 다른 사람은 30만명으로 보고하였다. 근래에 교통수단의 발달과 기계공업의 발전으로 여러 가지 복잡한 보상문제 또는 법적인 문제들이 야기됨으로 충분한 지식과 과학적인 판단이 더욱 필요하게 되였다. Sataloff는 jet engine no에서 종사하는 사람들에게서 난청은 한사람도 없었다는 보고도 있으나 Sterner는 85㏈∼100㏈의 소음으로 난청이 온다는 보고가 있으며 여하튼 80㏈ 이상의 소음장에서 일하는 사람은 주기적으로 청력검사를 시행하여 일시적인 청력피로가 있을 때 휴식을 취하게 함으로서 영구적인 불행을 방지하며 소음원에 대해서는 차음을 하고 근로자에게는 외이도에 적당한 plug 을 하든가 muff을 사용하여 피고용자와 고용인 양쪽에 다같이 이익을 도모하도록 노력을 하는 것이 우리의 의무일 것이다.하였다.2002년 4월에 최대치에 도달했다. 전체 숙주와 바이러스 밀도로 볼 때, 그들의 먹이사슬은 바이러스에 의한 사멸에 의해서 평형 상태로 유지되고, 바이러스의 밀도 또한 평형 상태를 유지하는 것으로 보였다. 이러한 시도는 우리나라 광양만 내에 존재하는 해양 바이러스의 생태적 분포 연구를 다루는 첫 번째 실험으로 사료된다.탄산염암 지역은 Ca-$HCO_3$형, 혼펠스 지역은 Na-K형과 $CO_3+HCO_3$형이 우세한 것으로 나타났다. 본 연구를 통해 달천 폐광산 지역의 광미적재지에서 $Ca^{2+},\;Mg^{2+}$ 및 $SO_4^{2-}$ 성분이 지하수에 다량 용해되어 지하수의 주 흐름 방향에 위치한 기반암 지하수에 유입되었음을 알 수 있었다.tic monks could not wear. to express their deep faith. So the rules of the samgha has been distorted. The samgha has enlarged day by day as a great huge religious association. There are many different shapes of Kasaya. The Buddhist samgha need to establish a minute and rigid rules of Kasaya to order living of monks and to teach the moral and educational life to ordinary people. That book of rule is Vinaya pitaka(율장) . There are many kinds of Vinaya pitaka. This paper surveys the rules of Kasa

정보통신 기기들의 가격하락과 인터넷의 발전은 사물인터넷이라는 새로운 분야를 탄생시켰다. 일상에 접하는 모든 사물들이 인터넷으로 연결되어 새로운 서비스를 창출하는 사물인터넷은 빅데이터와 결합되어 기존에 볼 수 없었던 새로운 형태의 비즈니스 영역을 개척해 나가고 있다. 이에 사물인터넷의 전망은 그 활용도에 있어서 무궁무진 하다고 말할 수 있다. 또한 이러한 사물인터넷 장비들의 원활한 연결을 위한 표준화 기관들의 연구도 활발한 편이다. 그러나 이러한 연구 중에 우리가 간과하는 부분이 있다. 사물인터넷 장비를 제어하거나 정보를 획득하기 위해서 장비와의 연동문제(IP주소, Wi-Fi, Bluetooth, NFC 등) 및 관련 애플리케이션 소프트웨어 또는 앱을 별도로 개발을 해야 한다. 이러한 문제를 해결하기 위해 기존의 연구방식들은 GPS 또는 마커를 이용한 증강현실 연구가 이루어져 왔다. 하지만 별도의 마커가 필요하고 마커의 경우 가까운 곳만 인식하는 단점을 갖는다. 또한 2D 기반의 카메라의 활용한 GPS 주소 활용한 연구의 경우 대상 장비와의 거리 인식을 할 수 없어 능동적인 인터페이스 구현의 어려움이 있었다. 이러한 문제를 해결하기 위해서는 기존의 복잡한 방법이 아니라 사용자가 눈으로 확인하고 간단한 조작만으로 장비와의 연동이 가능한 직관적인 방법이 반드시 필요하다. 본 연구는 향후 스마트폰에 탑재될 3D 깊이 인식카메라를 활용해서 별도의 마커 없이 거리측정 및 핸드폰의 센서정보를 연동해서 자동으로 공간 좌표를 계산하여 사물인터넷의 장비를 발견하고 해당 사물인터넷 장비의 정보 획득 및 제어가 가능한 방법론을 제안한다. 결과로 사용자 관점에서 별도의 사물인터넷 장비 연동문제 및 앱 설치에 대한 부담을 줄일 수 있다. 나아가 이 기술이 공공서비스와 스마트 안경분야에 활용된다면 공공 서비스 증대 및 많은 소프트웨어 개발의 중복 투자를 줄이게 될 것이다.

Most hospitalized children will experience physical pain as well as psychological distress. Preschool children's pain perception related to painful procedures can increase due to elevated anxiety and fear because they do not have understanding logical of their disease and hospitalization. In particular, they are distressed about needle - related procedures which are feared because they are seen to be a cause of bodily damage. This descriptive study attempted to identify pain perception levels in preschool children and their mothers. A self-reporting measurement and behavioral observation were used to collect the data. A total of 25 hospitalized preschool children and their mothers were investigated and data were collected about 60 painful procedures. Data collection was carried out by the researcher and two trained investigators from November first to December tenth. Three insruments were used to collect the data : Faces Pain Rating Scale(FPRS) developed by Beyer was used to measure the degree of preschool children's pain perception about painful procedures. The Visual Analogue Scale(VAS) devised by Huskisson was used to assess the degree of mothers' pain perception about their children's painful procedures. A Pain Behavioral Checklist based on the Procedure Behavior Check List by LeBaron and Zelter and modified by the researcher was used to observe behaviors of preschool children, their mothers, and nurses when the painful procedures took place. The data were analyzed by an SPSS program, and were tested using real numbers, percentages, Pearson correlation coefficient, t-test, and ANOVA. The results of this study are as follows : 1. Of all the painful procedures, the mean score for the FPRS for the preschool children's pain perception was 4.02 points, and the mean score for the VAS of mothers' pain perception was 10.92 points. 2. A Positive correlation which was statistically significant was found between the pain perception of preschool children and their mothers (r＝.53, p＜.01). that is, the higher the children's pain perception was, the higher their mothers' pain perception was. 3. The characteristics of the painful procedures related with children's pain perception as follows : The type of painful procedure was found to be statistically significant (F＝23.44, p＜.01), Among the three procedures Ⅳ starting was found to be perceived as the most painful procedures to the children. The greater the number of times that the procedure had been done, the higher the pain perception was (F＝4.44, p＜.01), and the longer the duration of the procedure, the higher the pain perception wa(r＝.30, p＜.05). Pain perception in the treatment room was higher than in the children's room(t＝6.30, ＜.01), pain perception in the mother's presence was the higher than when the mother was not present (t＝2.91, p＜.01). 4. The characteristics of the painful procedures related with the mothers' pain perception as follows : The type of painful procedure was found to be statistically significant(F＝6.01, p＜.01). Among the three procedures Ⅳ sampling was found to be perceived as the most painful procedures to the mothers. The greater the number of times that the procedure had been done, the higher the pain perception was (F＝5.95, p＜.01), and the longer the duration of the procedure, the higher the pain perception was (r＝.31, p＜.05). Pain perception in the treatment room was higher than in the children's room (t＝3.51, p＜.01), but pain perception in the mother's presence showed statistically significant no difference. 5. Of all of the 19 children's behaviors during the painful procedures, the most frequent behaviors observed Were as follows in order of frequency “crying”, “screamirig”, “facial grimacing”, “physical resistance”, Of all of the nine methers' behaviors, the most frequent by observed in “console children”, “hold children”, “applaud children”, Of all of the 11 nurses' behaviors during the painful procedures, the mast frequent in order were “smiling”, “physical restraint”, “console children”, “praise children”. 6. A positive correlation between children's and mothers' pain perception and children's behaviors was found to be statistically significant (r＝.65, p＜.01, r＝67, p＜.01). Also the relationship between children's and mothers' pain percertion, and mothers' behavior was found to be statistically significant (r＝.57, p＜. 01, 4＝.60, p＜.01). The relationship between children's pain perception and nurses' behaviors was also found to be statistically significant (r＝.46, p＜.01), but there was difference between mothers' pain perception and nurses' behaviors.

A review on the papers published in the Korean Journal of Air-Conditioning and Refrigerating Engineering in 1998 and 1999 has been done. Focus has been put on current status of research in the aspect of heating, cooling, ventilation, sanitation and building environment. The conclusions are as follows. 1) A review of the recent studies on fluid flow, turbomachinery and pipe-network shows that many experimental investigations are conducted in applications of impingement jets. Researches on turbulent flows, pipe flows, pipe-networks are focused on analyses of practical systems and prediction of system performance. The results of noise reduction in the turbomachinery are also reported. 2) A review of the recent studies on heat transfer analysis and heat exchanger shows that there were many papers on the channel flow with the application to the design of heat exchanger in the heat transfer analysis. Various experimental and numerical papers on heat exchanger were also published, however, there were few papers available for the analysis of whole system including heat exchanger. 3) A review of the recent studies on heat pump system have focused on the multi-type system and the heat pump cycle to utilize treated sewage as the heat source. The defrosting and the frosting behaviors in the fin-tube heat exchanger is experimentally examined by several authors. Several papers on the ice storage cooling system are presented to show the dynamic simulation program and optimal operation conditions. The study on the micro heat pipes for the cooling of high power electronic components is carried out to examine the characteristics of heat and mass transfer processed. In addition to these, new type of separate thermosyphon is studied experimentally. 4) The recent studies on refrigeration/air conditioning system have focused on the system performance and efficiency for new alternative refrigerants. New systems operating with natural refrigerants are drawing lots of attention. In addition to these, evaporation and condensation heat transfer characteristics of traditional and new refrigerants are investigated for plain tubes and also for microfin tubes. Capillary tubes and orifice are main topics of research as expansion devices and studies on thermophysical properties of new refrigerants and refrigerant/oil mixtures are widely carried out. 5) A review of the recent studies on absorption cooling system shows that numerous experimental and analytical studies on the improvement of absorber performance have been presented. Dynamic analysis of compressor have been performed to understand its vibration characteristics. However research works on tow-phase flow and heat transfer, which could be encountered in the refrigeration system and various phase-change heat exchanger, were seemed to be insufficient. 6) A review of recent studies on duct system shows that the methods for circuit analysis, and flow balancing have been presented. Researches on ventilation are focused on the measurement of ventilation efficiency, and variation of ventilation efficiency with ventilation methods by numerous experimental and numerical studies. Furthermore, many studies have been conducted in real building in order to estimate indoor thermal environments. Many research works to get some information for cooling tower design have been performed but are insufficient. 7) A review on the recent studies on architectural thermal environment and building mechanical systems design shows that thermal comfort analysis is sitting environment, thermal performance analysis of Korean traditional building structures., and evaluation of building environmental load have been performed. However research works to improve the performance of mechanical system design and construction technology were seemed to be insufficient.

1. Background and Purpose The faces of human being change as they grow older. We could know the characters of the each ages, through the facial comparison between the 30's, 40's and the 50's, 60's. As a conclusion, I carried out this Study because I thought that the errors of diagnosis would be reduced a lot through the standardization researches about the morphology of faces. 2. Objectives The object of this study is selected from the patients who were already diagnosed Sasang Constitutions at the department of Sasang Constitutional Medicine in Kyunghee Oriental Medical Center. The number of the patients were 69 men in 30's and 40's, and 74 men in 50's and 60's. 3. Method I took the photographs of front view and lateral view of the objectives by digital camera and obtained the 200 measure through the facial measurement program. I compared the measure of 50's and 60's with 30's and 40's by independant t-test. 4. Results 28 measures are different 30's and 40's with 50's and 60's in Soyangin, 31 measures in Soeumin, 40 measures in Taeumin. 5. Conclusion (1) Soyangin showed wider interpupillary distance in 30's and 40's than 50's and 60's. They also showed the large brow and cheek and their lips were thick and prominent and their ophyrion were prominent and their noses were wide and large and they showed wide bigonial breadth in 30's and 40's than 50's and 60's. (2) Soeumin showed the position of ears were higher and the brows were longer and larger in 30's and 40's than 50's and 60's. The width of both eyebrow were wider in 50's and 60's than 30's and 40's. The lower 2/3 portion of the face was longer and the shape of head was longer in vertical in 50's and 60's than 30's and 40's. (3) Taeumin showed the wider brow in 30's and 40's than 50's and 60's. The width of each eyes was wider and the width of cheek and face was larger, too. The ophyrion was prominent and the mouth was bigger and the face showed longer in 50's and 60's than 30's and 40's. (4) The upper 1/3 portion of the face was large in 30's and 40's and the lower 2/3 portion of the face showed large and long in 50's and 60's regardless Constitution.
