Currently the evaluation of high school science and mathematics learning has been too much knowledge-centered without concerning the inquiring ability or scientific attitude. This study, therefore, was made for the purpose of establishing of evaluation model for high school science (biology and earth science) and mathematics learning and its evaluation items. In this paper, the research was done about three fields, biology, earth science and mathematics. 1. For the biology, the evaluation methods of inquiry learning were studied with the foreign references, and proper evaluation items were suggested. 2. For the earth science, after analizing 5 kinds of earth science textbook of current using in high school, essential 19 items were selected. 5 of them were tested in test group and control group, then, the results were analized. 3. For the mathematice, the teaching elements of「Set」and「Flow chart」in mathematics (Ⅰ) were selected and structured. Detailed teaching objects were established and evaluation items were introduced.

Various cutaneous as well as myocutaneous flaps have been designed for the reconstruction of tissue defects caused by the excision of oral cancer. Among these flaps, cervical island skin flap have been introduced by Farr et al and more have developed by Tashiro et al. This flap has many advantages. The flap minimizes donor size by use of cervical operation wound, flap size available is adequate for most oral defects and the procedure is relatively simple and time saving. However, this flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We used this flap for it's rapid simple, and effective, primary closure of oral defects after cancer ablation and we have found this flap very useful for the reconstruction of relatively small oral defects.

The purpose of this study was to investigate the level of acrylonitrile(AN) exposure in workplace air and body burden of AN as a form of hemoglobin adduct. The mean of AN concentration of 10 workplaces was 0.24ppm(GSD 4.80) which was under TLV(2ppm). But 7% of 140 measurements and 5 of 10 workplace was over TLV. The GM of hemoglobin adduct detected with cyanoethy-Ibaline(CE) in 110 biological monitoring was 1.51nmol/g globin(GSD 3.43). The correlation coefficient between AN concentration in the workplace air and the amount of hemoglobin adduct measured by CE concentration was 0.56. And the equation showed y= 2069.1 + 1861.2. If 2ppm of airborne AN TLV insert to that equation, the concentration of hemoglobin adduct detected with cyanoethlvaline is 6.0nmol/g globin and this value means biological indices(BELs) of ACGIH. 8% of workers showed over 6.00nmol/g globin. For most of workers were exposed to AN intermittently according to their special assignment of that day, ambient monitoring for a day could not effectively represent their body burden. And it was very good compensation for ambient monitoring to evaluate each worker's cumulative exposure by biological monitoring of hemoglobin adduct detected with cyanoethylbaline.

Background: Reperfusion of ischemic myocardium has been postulated to result in a specific oxygen radical mediated tissue injury. Iron may liberate during ischemia and we hypothesized that administration of the iron chelator, deferoxamine during ischemia would result in improved recovery after postischemic reperfusion. Purpose: To test whether iron-catalyzed processes contribute to myocardial necrosis during ischemia and reperfusion, deferoxamine was administered to block iron catalyzed hydroxyl radical formation in rabbits. Methods: Eleven rabbits were divided into two groups : control group (n=5) and deferoxamine pretreatment group (n=6). The left circumflex coronay artery was ligated for 30 minutes and reperfused for 180 minutes. Area at risk (AR) was measured by non-stained area with methylene blue injection into left atrium after left circumflex coronary artery ligation. Infarct size was measured by weighing after triphenyltetrazolium chloride staining. Heart rate was measured using electrocardiographic recording and systemic blood pressure was monitored by pressure transducer connected to the catheter in the left ventricle. Results: 1. There was no significant difference of heart rate and blood pressure in deferoxamine pretreatment group compared with control group. 2. There was significant decrease of serum iron concentration after continuous infusion of deferoxamine compared with serum iron concentration before ligation of coronary artery(P<0.05). 3. There was no significant difference of area at risk between control and deferoxamine pretreatment group. 4. Area at necrosis to area at risk was significantly reduced in deferoxamine pretreatment group compared with control group(P<0.05). The results suggest that deferoxamine infusion prior to coronary artery occlusion has a significant benefit in reducing infarct size in this model.

목 적 : 1980년대 후반부터 산업보건에서 혈중 및 요중 중금속농도 분석의 정확성 문제가 크게 부각되었다. 같은 시료를 가지고 분석기관마다 보이는 커다란 오차로 인해 직업병 진단 결과에 대한 신뢰성을 크게 감소시켰다. 이에, 노동부에서는 1992년부터 특수건강진단 기관에 대한 생체시료 분석정도관리 프로그램을 시작하였다. 본 연구는 1995년부터 시작된 생체시료 분석정도관리 5년간의 결과를 보고하고, 현재 생물학적모니터링으로 사용되는 항목과 빈도를 조사하고 이 항목의 정도관리 참여율을 비교하여 산업보건 관계 연구나 직업병 관리에 참고할 수 있도록 하기 위해 실시하였다. 방 법 : 생체시료 분석정도관리는 무기와 유기분석분야로 나누어 일년에 전후반기 2회 실시하고 있으며, 지정항목과 자율항목으로 구분하고 있다. 지정항목인 혈중 납과 요중 마뇨산은 분야별로 한 번에 3개 농도수준을 주어 2개 이상이 기준값의 ±15%내외의 범위에 들면 적합한 것으로 판정하고 있으며, 자율항목은 2개의 시료를 주어 2개 모두 기준실험실 평균값의 ±3SD 내외의 범위에 들면 적합한 것으로 판정하고 있다. 결 과 : 지정항목인 혈중 납과 요중 마뇨산 분석은 평균 적합률이 각각 89%, 90% 이었고, 대학기관, 비영리법인, 종합병원, 사업장 자체기관별로 차이는 없었으나 신규 기판의 적합률 70% 수준으로 상대적으로 낮았다. 자율항목의 적합률은 평균 50% 수준이었고, 저농도보다는 고농도의 적합률이 떨어졌다. 국내에서 가장 많이 분석되고 있는 항목은 요중 마뇨산과 혈중 납이었고, 혈중 및 요중 망간도 많이 분석되고 있었다. 요중 삼염화물, 페놀, 만델산, 카드윰, 메칠마뇨산, 크롬 등도 많이 분석되고 있는 항목이었다. 혈중 망간, 요중 수은, 요중 NMF는 정도관리에서 적합판정을 받은 기관의 숫자보다 실제 분석을 하고 있는 기관의 숫자가 많았다. 결 론 : 지난 5년간의 생체시료 분석정도관리 결과 우리나라 분석실험실의 분석능력은 향상되고 있으나, 자율항목에 대한 분석능력은 아직 미흡한 것으로 나타났다. 그리고, 아직 일부 일부 항목에 대해서는 외부 정도관리 없이 분석되고 있는 경우도 있었다. Objective : The accuracy of analytical results of blood and urine heavy metals came out to the main issue on occupational health from late eighties. The discrepancy of the results for same samples from different laboratories made the diagnosis for occupational diseases be unreliable. Therefore, a quality control program for analysis of samples taken from workplace had been introduced in Korea since 1992. This study aims to show the quality control program for analysis of blood and urine samples and its proficient rates from 1992 to 1999 and to know how they have been being used in occupational health. Methods The quality control program runs twice a year with mandatory items of blood lead and urine hippuric acid and voluntary items of blood cadmium and manganese and urine mandellic acid and methyl hippuric acid. Participant laboratories are receiving three levels for each items and two out of three samples have to be qualified for being a profi-cient laboratory for the item. The acceptable range of blood lead and urine hippuric acid is ± 15% and that of the others is within 3 SD (standard deviation) from the reference values. Results : The proficient rates of blood lead and urine hippuric acid was 89%, 90%, repectively, however those of the other voluntary items have been from 51% to 62%. The proficient rates of urine mercury and urine N-methylformamide (NMF), which are introduced since 1999, were very poor. Urine hippuric acid and blood lead were analyzed frequently for the purpose of biological monitoring conducting by special health examination organizations. Urine and blood manganese and urine metabolites of trichloroethylene, urine phenol, methylhippuric acid and cadmium were followed. Conclusions : In conclusion, the quality control program for biological monitoring has dramatically improve the ability of analysing blood and urine samples and eventually con-tributes to diagnose occupational diseases and to prevent occupational poisoning. However, some biological monitoring data, such as urine manganese, mercury and NMF, have been still reported from laboratories that were not accepted as a proficient laboratory.

Oral examinations were conducted before the experiment started. The students were given common toothbrushes (control group) or spring-attached toothbrushes (experimental group) and instructed to brush their teeth by scrubbing method. Measurement of plaque index and count of salivary bacteria were done at 0, 1, 3, and 5 weeks. 1. Mean plaque index was significantly reduced at week 1 compared with at week 0 in both groups. (P<0.05) 2. Mean plaque index was significantly reduced at week 3 compared with at week 1 in the experimental group. (P<0.05) 3. Mean plaque index was significantly reduced at week 5 compared with at week 3 in the experimental group. (P<0.05) 4. There were no significant differences of mean plaque index among week 1, week 3, and week 5 in control group. (P>0.05) 5. The number of salivary bacteria was slightly reduced during the experiment, however there was no statistical significance. (P>0.05) To reduce the plaque effectively, the use of spring-attached toothbrush should be recommended, and adequeate instruction for children is needed.

88 workers exposed to cadmium were examined at the 12 factories using or producing cadmium in order to know the present state of cadmium exposure and renal dysfunction in 1992. Cadmium in blood and in urine were measured and compared by the 3 exposure level of cadmium in air. Cadmium in blood of low, moderate and high exposure group were 2.5, 3.8 and 7.6 ㎍/L, respectively. Cadmium in urine were 1.8(1.3), 3.8(2.6) and 7.9 ㎍/L(6.1 ㎍/g creatinine), respectively. However, there was no relationship between urinary cadmium and β₂-microglobulin. Cumulative exposure estimate(CEE) was calculated by multiplying the mean ambient cadmium level of the factory and working duration. CEE has a high correlation with cadmium in blood and urine, but no relation to β₂-microglobulin. Because working durations were relatively shorter than European workers', the highest CEE was just 300 ㎍·year/m³, which was not enough to induce renal tubular dysfunction. This study, however, suggested the possibility that renal tubular dysfunction caused by cadmium could be happened in Korea in the near future.

근로자의 경영참여가 기업성과에 미치는 영향에 관한 연구

박성규,양석균 가톨릭대학교 사회과학연구소 2007 社會科學硏究 Vol.23 No.-

오늘날 기업환경은 국제화, 정보화, 지식중심, 경쟁의 심화, 의사결정 속도 등으로 요약 될수 있을 것이다. 이러한 환경이외에도 인간환경문제, 지방화, 사회공헌, 경영민주화 같은 문제들이 기업의 성과에 영향을 주고 있다. 이와 같이 복잡한 기업환경에서 기업은 경영효율성과 장기적인 지속경영 목표 달성을 위해 다양한 경영전략을 시도하고 있다. 복잡한 기업 환경중의 하나인 근로자 경영참여는 오늘날 경영자와 근로자 모두에게 중요한 관심사이며 이에 대한 적절한 대처방안이 기업의 효율성과 장기적 성과에 영향을 주고 있다. 근로자 경영참여는 산업민주화로 인해 촉발되고 오늘날 정치 경제의 발전 으로 인해 그 중요성이 더욱 증가되고 있다. 김대환은 국제노동기구가 정의한 노동자의 경영초배를 다음과 같이 인용하였다. 즉 노동자 경영참여란 “노동자가 경영조직상의 지휘계통을 넘어서 조직적으로 경영상의 의사결정과정에 참여하여 사용자와 대동하고 자유로운 입장 에서 발언권을 행사하는 것”이다. 그는 노동자의 경영참여의 의의로 다음과 같은 것들을 지적한다. 노동자의 경영참여로 인해 노동자의 이익을 보호 증진시키며, 노동자의 소외 현상을 극복하게 하고 기업의 효율성을 증대시키며, 산업 민주 주의 를 실현할 수 있게 하고, 지역발전 및 사회문제 해결에 기여할 수 있게 한다. 그러나 모든 경영전략이 그렇듯 근로자 경영참여가 기업의 장단기 경영성과에 항상 긍정적 영향을 주는 것은 아니다. 기업의 내외적 시간적 환경과 경영자와 근로자의 개별기업 특수성으로 인해 좋은전략도 성과에 부정적 영향을 줄 수도 있다. 본 연구는 경영자와 근로자들의 중요한 관심사이며 경쟁전략 중 하나인 근로자 경영침여가 기업성과에 어떠한 영향을 주는지에 대해 알아보고자 한다. 역사적으로 볼 때 노동자의 경영참여는 노동운동이 지향해 온 핵심 과제의 하나였다. 그러나 많은 기업들은 노조의 경영 참여로 인한 경영 독립성 침해 우려로 경영참여를 반대하기도 한다. 경영지들의 입장에서 보면 노동자들의 경영 참여는 장단점을 함께 가지고 있다. 노동자들의 경영참여는 노동자들의 헌신을 이끌어내어 기업성과에 긍정적 영향을 주기도 하지만 한편으로는 경영자의 의사결정권이 약화되어 노사가 대립하면 기업성과에 악영향을 줄 수도 있다. 이와 같은 미묘한 속성 때문에 노동자 경영참가 문제는 연구자의 관점에 따라 그 결과가 달라질 수도 있다. 이전의 근로자 경영참여는 노동운동, 근로자 경영참여 입법, 혹은 기업의 도산과 같은 사건들에 의해 촉발되었다. 오늘날의 근로자 경영참여는 국제화, 민주화,근로자 삶의 질 등과 같은 전반적인 경영환경의 변화와 함께 경영자와 근로자의 경영에 대한 기본인식의 변화에 의해 이끌어져 나오고 있다. Worker’s management participation is a great concern for both the chief executives and the workers in the Korean companies due to the economic as well as political development. Worker’s management participation is believed to increase the organizational efficiency through the aligned cooperation between workers and chief executives, which would then lead to increased sales. The purpose of this study is to find out the impact of management participation on corporate performance. With the fifty two valid samples it is found out by the independent t sample test that the higher management participation group showed higher sales and cooperative atmosphere compared to the lower management participation group. The correlation coefficient also showed that the management participation is significantly correlated with the corporate sales and cooperative atmosphere. This pilot study has some weakness. The sales variable might be a surrogate variable for the corporate size. A study is needed that will control for the corporate size. Net income increase rate and stock return rate might be a better variable to measure the corporate performance level. A sophisticated operational definition is required to measure the worker’s management participation in the following studies.

OK-432(Picibanilⓡ)와 외과적 절제술을 이용한 선천성 림프관종의 치험례

김일규,이성호,오성섭,최진호,오남식,김왕식,임영일,양동환 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.3

Lymphangiomas are relatively rare benign tumors of the lymphatic system, characterized by congenital lymphatic malformation such as anastomosis or obstuction of the lymphatic channels. There are most frequently diagnosed in children younger than 3years. In contrast to that of the hemangioma, the sex distribution of the lymphangioma is nearly evenly divided. The head and neck lymphangioma represents about 70∼75% of all lymphangiomas, and they are difficult to manage. Spontaneous regression is rare, and rapid intermittent enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequelae such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosants. Problems associated with surgical excision include the risk of cosmetically unacceptable scarring and the risk of damage to surrounding vital stricture and the high risk of incomplete excision. The sclerosants previously used have numerous other local and systemic side effects. This report describes a case that was successfully treated using OK-432 as a new sclerosant drug and secondary surgical excision for congential cavenous lymphangioma extensively enlarged to tongue, mouth floor and submandibular region.
