The purpose of this retrospective research of 603 patients who were transferred to the emergency medical center of university hospital from 1 Jan, 1998 to 31 Jan, 1998 was making of basic data for emergency medical transfer system improvement countermeasure and the point at issue of overlapping reexamination ststus of patients transfered to emergency medical center of university hospital from 1,2 level hospital. The data analysis was done by SPSS, t-test, ANOVA, Pearson correlation. The results were as follows: 1. Male to female ratio was 1.7:1 and peak age group was patients over forties and under nine years of age(70.5%) 2. Traumatic patients were 17.8%, motor vehicle accident patients were 16.7% and Non-traumatic patients were 65.3%. Transferring hospital was divided into 2groups: primary hospital, secondary hospital. The majority was secondary hospital(73.3%). The result of symptom severity classification of patients transferred to 3rd emergency medical center was urgent patients 32.5%, emergency patients 33.58%, non-emergency patients 34.0% 3. Most highest score items amoung overlapping reexamination of patients transfered to emergency medical center of university hospital from 1,2 level hospital were CBC test, simple X-ray (0.93점), CBC test(0.97점), urin test(0.88점), chemistry test(0.94점), simple X-ray(0.98점), CT(0.42점), EKG(0.89점) amoung overlapping reexamination of motor vehicle accident patients were more higher reexamination score than traumatic patients and non-traumatic patients 4. CBC test(P<0.001), urin test(P<0.001), chemistry test(P<0.001), simple X-ray(P<0.001), CT(P<0.01), EKG(P<0.001) amoung overlapping reexamination of patients in 2 level hospital were more higher reexamination score than 1 level hospital patients 5. About symptom severity classification of patients transferred to 3rd emergency medical center, CBC test(P<0.001), urin test(P<0.001), chemistry test(P<0.001), simple X-ray(P<0.01), CT(P<0.001), EKG(P<0.001) amoung overlapping reexamination items in urgent patients were more higher reexamination score than other patients 6. Influencing variation for overlapping reexamination in hospital was CBC test(P<0.001), CT (P<0.001), MRI (P<0.05).

The study was purposed to know the status of health management in small-scale-industries which have less than 50 employees. A total of 330 small-scale-industries were surveyed by nurses and industrial-hygienists who were affiliated with industrial health care agency from January, 1993 to December, 1994. The contents of survey include status of work environment, occupational accident and its disease availability, protective evice, health education and settlements. The results were as follows: 1. The number of industrial accidents(death, injury arid occup. disease) in 1994 was 83 which was reduced from that of the 1993 which was 126. 2. As a result of the measurement of work environment the excessive ratio of permitted criteria was reduced to 20.6% in 1994 from 264% in 1993, and the improvement ratio of work environment was increased to 39.5% in 1994 from 29.7% in 1993. 3. The contents of health education at work place were as follows: general disease(25.4%), work environment(20.2%), protective device(16.7%), disease prevension(14.2%), occupational disease(85%), and health promotion(8.3%). 4. In terms of industrial safty and prevention of occupational disease, only 10.6% was satisfactory or excellent, and the 89.4% was poor, inadequate or required reexamination.

$L{\acute{e}}veill{\acute{e}}$가 상당수의 한국산 신분류군을 기재하였음에도 불구하고, 이들 분류군에 대한 종합적인 분류학적 검토가 아직까지 국내에서 수행된 바가 없다. 본 논문에서는 $L{\acute{e}}veill{\acute{e}}$가 Decades plantarum novarum이라는 연속 논문에서 한국에서 채집된 표본을 근거로 신분류군으로 발표한 것들의 실체를 파악하기 위하여, 지금까지의 연구 결과를 비교 검토하였다. 그 결과 $L{\acute{e}}veill{\acute{e}}$의 의해 총 275개의 신분류군이 발표되었음이 확인되었다. 이들 가운데에는 Hydrolirion $H. L{\acute{e}}v.$이라는 신속도 포함되어 있으나, 이는 현재 Blyxa Noronha ex Thouars와 같은 분류군으로 간주되고 있다. 나머지 분류군들은 종 수준에서 231개 분류군, 변종 수준에서 43개 분류군이 포함되는 것으로 확인되었다. 종 수준으로 보고된 분류군 중, 현재까지 종 또는 변종 수준에서 인정되는 분류군은 17개였고, 학자에 따라 종 또는 이명으로 간주되는 분류군은 52개로 파악되었으며, 151개 분류군은 다른 분류군과 동일한 것으로 처리되었다. 한편, 11개 분류군은 국내 학자들에 의해 소개되지 않은 것으로 확인되었다.

Knowledge of the degree of yield reduction due to water stress at different crop growth stages in rice production is important for rational scheduling of irrigation during periods of insufficient water supply. Previous studies to determine the degree of yield reduction duo to water stress suffered from interruptions by rain during experiment. Also the findings did rot relate the degree of water stress to the soil water potential and water deficit status of rice plants. In this study, two years experiments were conducted using the high yielding rice varieties, an Indica x Japonica (Nampoong) and a Japonica variety(Choochung). These were grown in 1/200$^{\circ}$ plastic pots placed under a rainfall autosensing, sliding clear plastic roof facility to control rainfall interruptions. The results obtained were as follows. 1.The two varieties differed in the growth stage most sensitive to water stress as well as the degree of yield reductions. When rice plants were stressed to the leaf rolling score 4 and soil water potential of about - 20 bar at major crop growth stages which included heading, booting, non-effective tillering, panicle initiation and early tillering stages, the yield reductions in the Indica x Japonica variety were 58%, 34%, 27%, 22%, and 21%, respectively, whereas in the Japonica vairety they were 23%, 36%, 1%, 13% and 22%, respectively. This result show that the recommended drainage during non-effective tillering is valid only for the Japonica variety. Sufficient irrigation at booting, heading and early tillering stages are necessary for both varieties. 2.The two varieties showed visible wilting symptoms when the soil water potential dropped to about - 3.0 bar. The Japonica variety showed more leaf rolling than the Indica X Japonica. However, it had a higher retention of leaf water content and greater stomatal diffusive resistance. When the soil water potential dropped, the Japonica variety showed leaf rolling score (LRS) 1 at 0 soil-5. 0 bar and LRS 2 at 0 soil -6.0 bar while the Indica X Japonica showed LRS 1 at 0 soil - 5.5 bar and LRS 2at 0 Soil - 9.0 bar. The stomatal diffusive resistance was maximum at the second top leaf blade in both varieties at intermediate water stress of 0 soil - 4.5 bar. 3.The number of days that was required for the soil water potential to drop to-3. 0 bar and to - 20.0 bar after drainage of irrigation water from the 20cm deep silty clay loam soil in the pots were 6 and 13 days, respectively for booting stage, and 7 and 11 days, respectively for heading stage, 9 and 12 days, respectively for panicle initiation stage, and 12 and 19 days, respectively for early tillering stage. 4.Water stress during the early tillering stage recorded the longest delay in beading time, the largest reduction in panicle numbers and a substantial yield decrease of 20%. This calls for better water management to ensure the availability of water at this stage, particularly during drought periods. In addition, a reexamination of the conventional inter-drainage practice during the non-effective tillering stage is necessary for the high yielding Indica X Japonica varieties.

마케팅 사상사에서 지금까지 지속되고 있는 중요한 개념 중의 하나는 소비재의 분류에 관한 것이다. Copeland(1923)가 최초로 제안한 상품분류방식과 이론은 지금까지 거의 수정되지 않은 채 학계와 실무자들이 원용하고 있고 미국 마케팅 협회를 비롯한 유관기관들도 이를 공식적으로 인정하고 있다. 그러나 그의 분류방식은 오늘날에는 시대에 뒤떨어진 낡은 것이 되어 현대의 상품광고, 소매업 및 소비에 적절하지 않은 것으로 점차 알려지고 있다. 그러한 방실은 특히 현대사회에서 소비자들이 스타일, 개인적 정체성 및 사회적 지위나 신분에 집착하고 있음으로 인하여 소비자 시장을 잘 이해하고 있는 브랜드 관리자들이 중점적으로 촉진하고 있는 상품의 사회적 특성이 소비자의 선택과 구매자 행동의 핵심적 결정요인이라는 사실을 수용하지 못하고 있다. 이에 따라 본 연구자는 기존의 상품분류방식이 다년간 시장조건의 변화에 대응하지 못하고 있는 이유를 탐구하고 그것이 소비와 소비자행동에 영향을 미치는 다수의 요인들을 반영하지 못하고 있다는 것이 가장 중대한 약점임을 주장하였다. 한걸음 더 나아가 기존의 연구문헌을 토대로 그러한 약점을 극복할 수 있는 새로운 상품분류방식을 제안하였다.

정확한 분자병리검사를 위해 검체에 대한 질관리의 중요성이 강조되고 있다. 본 연구에서 BRAF, EGFR, KRAS 돌연변이 검사에 대해, 검체 종류 및 처리과정 중 DNA 품질에 영향을 미치는 인자를 알아보고자 하였다. 모두 1,772건의 분자병리검사에 대해, 검체의 종류, 포르말린 고정시간, 재검기록 등 DNA 품질에 영향을 미칠 수 있는 임상병리학적 요소를 조사하였다. 세포검체는 고정액으로 처리를 한 검체보다 생리식염수에 보관한 검체가 DNA 품질이 좋았다. 조직검체는 10% 중성 포르말린에 24시간 이내에 고정된 검체가 그 이상 고정된 검체보다 DNA 품질이 좋았다. 검체 종류 중 신선조직검체, 그리고 종양세포밀도가 높은 조직검체가 파라핀포매조직 및 세침흡인액상 세포검체보다 상대적으로 DNA 품질이 좋았다. 10% 중성 포르말린에 24시간 이상 오래 고정된 검체일수록 Non-PNA Ct값이 비례 증가하여, 포르말린 고정시간이 검체 DNA 품질에 영향을 준다는 것을 확인하였다. 결론적으로 종양세포의 밀도 및 적절한 포르말린 고정시간이 DNA 품질을 유지하는데 가장 중요한 요소이며, 신속하고 정확한 분자병리진단을 위해 이들 요소를 적절히 관리하여 최적의 DNA 품질을 유지하도록 해야 한다.
