자료분석 결과 발견된 사실들을 정리해 보면 다음과 같다. 첫째, 직장에서 발생하는 성적 성가심에 대해 상대적으로 적극적으로 대응하는 여성들은 약 50.6%정도로 나타났다. 이 중에서도 성적 성가심에 대해서 불쾌하게 인식하는 정도도 상대적으로 높고, 불쾌감을 상대에게 표현하며 대응하는 정도도 상대적으로 높은 여성들은 전체 응답자(736명)중에서 약 40%(294명)정도 였다. 성적 성가심에 대하여 불쾌함을 인식하는 정도는 상대적으로 낮으나 상대에게 불쾌함을 표현하며 대응하는 수준은 상대적으로 높은 여성들이 약 10.7%(79명)로 나타났다. 반면에 성적 성가심에 대하여 불쾌하게 인식하는 정도도 상대적으로 낮고 불쾌함을 상대에게 표현하는 정도도 낮은 여성들이 약 32.8%(242명)나 되었다. 약 16.4%(121명)의 여성들은 성적 성가심 상황에서 불쾌하게 인식하는 정도가 상대적으로 높으면서도 상대에게 불쾌감을 표현하며 대응하는 정도는 상대적으로 낮았다. <표 4> 둘째, 직장에서 발생하는 성적 성가심 상황에서 여성이 상대에게 성적 성가심에 대한 자신의 불쾌함을 표현하며 대응하는 능력은 여성의 심리적 특성인 대인의존성과 밀접한 관계가 있다는 사실을 명백하게 확인하였다. 성적 성가심 상황에서 성적 성가심에 대해 상대적으로 불쾌하다고 인식하는 정도가 높으면서 불쾌감을 표현하고 대응하는 수준은 상대적으로 낮은 여성들은 대인 의존도가 상대적으로 높았고, 반대로 성적성가심에 대해 상대적으로 불쾌하게 인식하는 정도가 상대적으로 낮으면서 불쾌감을 표현하며 대응하는 수준은 상대적으로 높은 여성들은 대인 의존도가 상대적으로 높게 나타났는데 이는 주목할만한 사실이다. 세째, 성장시 부모의 상호작용 유형이 성적 성가심과 같은 이성과의 상황에서의 여성들의 대응 반응과 밀접한 관련성이 있음을 발견하였다. 성장시 아버지가 지배적이고 어머니가 순종적인 특성이 뚜렷한 가정에서 성장한 여성들은 부모의 상호작용 유형이 동등한 가정 분위기에서 양육된 여성들에 비해 성적 성가심 상황에서 불쾌함을 표현하며 상대에게 대응하는 수준(강도)자체가 훨씬 낮았고, 성적 성가심에 대해 자신이 불쾌하게 생각하는 정도보다 상대적으로 훨씬 약한 소극적인 대응반응을 보이는 사실도 확인되었다. 성적 성가심 상황에서 상대 남성에 대한 여성들의 대응 반응은 성장시 남성인 아버지에 대한 여성인 어머니의 태도 및 행동의 재현(reenactment)현상으로 나타났다고 해석할 수 있다. 이러한 발견은 특히 동성인 부모가 성역활 사회화의 가장 강력한 모델이라는 학습 이론가들의 주장을 거듭 뒷받침하여 준다.

The early developmental stages, growth and morphological changes of the Korean bullhead, Pseudobagrus fulvidraco, were studied from a series of reared specimens. Details of the early developmental stages are illustrated with special reference to morphological transformations. Egg and sperm of Korean bullhead were obtained from mature adults under hormonal treatment, fertilized artificially, and incubated in the aquarium. The incubation period of fertilized eggs was 55 to 66 hours at a temperature of 24.9${\pm}$0.34$^{\circ}$. Larvae were fed successively with Artemia salina and Daphnia magna for 2 to 15 days and artificial food after 20 days. Fertilized eggs were adhesive and spherical with a diameter of 2.04mm(n = 100). The mean total length of newly hatched larvae was about 4.92${\pm}$0.33 mm. Mouth opening occurred on one-day-old yolk-sac larvae, and initial feeding was observed on the third day after hatching. The morphological transitions from larvae to juvenile and juvenile to young stages occurred when the fish reached about 17 mm in total length (about 13days after hatching) and about 32 mm in total length (about 30 days after hatching), respectively. Many changes in proportion of body parts to total length were observed at about 7~8 mm and 30~32 mm, corresponding to the transformations from larvae to juvenile and from juvenile to young, respectively. In comparing relative growth of each body part against total length, those characteristics related to head parts showed positive growth in the pre-larval stages, while those concerning mobile abilities showed positive growth in the post-larval stage.

The age and growth of the short-necked clam, Paphia undalata, was investigated from 546 samples randomly collected in December 2000 in Kwangyang Bay, Korea. Ages were determined from ring radius of shell and the maximum age was observed to be 2 years. The relationship between shell length (SL) and shell height (SH) of Paphia undalata was SL = 0.2105 ＋ 1.7569 $\times$ SH ($R^2$= 0.98), and the shell length (SL)-total weight (TW) relationship was TW = 2.5824 $\times$ 10$^{-4}$ $\times$ S $L^{2.6769}$ ($R^2$= 0.92). The von Bertalanffy growth parameters were estimated by the non-linear method, with values as follows: $L_{\infty}$ = 81.46 mm, K : 0.20/year, $t_{0}$ = -1.19 year. The von Bertalnanffy growth equation was $L_{t}$ = 81.46(1- $e^{-0}$.20(t+1.19)/), $W_{t}$ = 33.68(1- $e^{-0}$.20(t+1.19)/)$^{2.6769}$.

The black soldier fly larvae are able to decompose various organic wastes such as livestock manures and food wastes. We tested whether the quality of the insect derived compost, i.e. larval feces, was comparable to that of a commercial fertilizer. Chemical analysis of Hermetia. illucens compost was suitable as a fertilizer. When the kidney bean (Phaseolus vulgaris L.) was raised on the culture soil treated with the H. illucens compost, the growth of leaf area, total dry weight and leaf dry weight increased significantly. The H. illucens compost is thought to act as an increasing factor of RGR (relative growth rate) from the beginning of growth and also had a great effect on the relative growth rate throughout the late stage of growth. There is high statistical significance between NAR (net assimilation rate) and RGR (relative growth rate), but no significance between RGR and LAR (leaf assimilation rate) of the treatments. In addition, the treatment of H. illucens compost promoted the thickness of leaves from the beginning of growth and the tendency of thickening leaves from the beginning of growth and the effect continued throughout the late period of growth. When mixed with 50% of H. illucens compost rather than 25%, it showed the greater effect on the plant growth.

인자로 중대사고시 생성되는 흡습성(hygroscopic) 에어로졸의 거동을 해석적인 방법을 이용하여 분석하였다. 분석한 내용는 상대습도가 불포화, 포화, 과포화 조건에서 CsOH 에어로졸의 수증기 응축률, 입자성장에 따른 크기분포의 변화. 중력침전에 의한 전체 에어로졸량의 변화이다. 용질효과를 고려한 흡습성 에어로졸 모델을 사용한 경우 상대습도가 불포화 조건에서도 에어로졸 입자에 수증기 응축이 발생하며 입자의 크기가 평형반경에 달할 때까지 지속됨을 발견하였다. 이러한 입자 성장은 매우 빠른 입자크기분포 변화를 초래하여 중력침전에의한 급속한 에어로졸 감소를 초래하는 것으로 예측되었다. 따라서 현재 사용되고 있는 MELCOR 및 CONTAIN 코드는 흡습성 에어로졸에 대해서 용질효과를 고려한 모델을 사용하여야 할 것이다.

Growth rates of oysters at four oyster farms in Hansan-Geoje Bay, near Chungmu, southern Korea, and density-dependent relative shell growth were investigated from November 1979 to May 1980 with the following results: The oysters at Sorang farm showed the best growth, the shell height in May 1980 attaining 10.10 cm, at Hwado 8.69cm and Songdo 8.57cm, all of which started growing in June 1979. At Chubong the oysters which started growing in July attained 8.6cm. The best grown oysters at Sorang shelved relatively slow growth in meat weight until February 1980, and then showed rapid growth upto May. At Hwado and Songdo they grew fast from December 1979 to February 1950, and from April to May 1980. Those at Chubong gradually increased growth rate from December 1979, and in April and May they showed rapid growth but still being smaller than the others. The ratio of meat weight to shell weight increased at Whado, Songdo and Chuhong after December 1979, but at Sorang it increased rapidly after February 1980. The ratio of shell length to shell height was 0.60 and up when the individual number of oysters attached to each cultch-disc(oyster shell) was less than 13, 0.56 to 0.60 when 14 to 25, and 0.51 or less when over 28, respectively.

본 연구는 한국 제조업의 기업별 <패널>자료를 이용하여 확율 적 생산함수를 추정한 다음, 우리 나라의 주종 수출산업인 섬유산업과 전자산업의 기술적 효율성이 1980년대에 하락한 이유를 규명하기 위하여 동종산업내의 각 기업들의 기술적 효율성의 결정요인을 계량분석을 통해 분석하였다. 성장산업인 전자산업과 사양산업인 섬유산업의 산업 내 (intra-industry) 기술적 효율성의 결정요인은 상하였다. 성장산업인 전자산업의 경우, 상대적인 기업의 크기와 노동비용의 상대적 크기는 기술적 효율성과 각각 정의 관계를 보이고 있는데 비해, 사양산업인 섬유산업의 경우, 총 매출액에서 수출이 차지하는 비중과 기술적 효율성과 반의 관계를 보였다. 즉 1980년대 섬유산업의 기술적 효율성이 하락한 중요한 요인은 동 산업의 수출부진과 상대적인 노동비용의 상승을 들 수 있으며, 성장산업인 전자산업의 경우는 일부 대기업의 집중도 심화가 동 산업의 평균적 기술적 효율성의 하락요인이 되었음을 알 수 있다. 따라서 본 연구는 경쟁의 촉진과 기업 집중도의 완화가 기술적 효율성을 향상시키는 데 중요하다는 점을 보여주고 있다.

Morphological characteristics of the topshell, Turbo cornutus Solander were studied on the basis of shell growth and fatness from April 1978 to October 1979. The Sampled areas were coastal waters of Jeju City, Seongsanpo, Moseulpo and Seogwipo in Jeju. The average shell length of the topshell from Jeju City area was smaller than those of the other three areas, and also the spine number of the 1st row on the shell from Jeju City area was fewer than the others. Sex ratios from each areas represented about 1:1. The relationship between shell length and shell breadth showed regression line and the value of slope for the specimen from Seongsanpo was the lowest. The relationship between shell length and total weight showed exponential curve, and the value was the highest in the specimens from Moseulpo. The value of slope on the relationship between total weight and meat weight was the highest in those from Moseulpo and the lowest from Jeju City. The regression line of relationship between total weight and meat freight in those if Jeju City area showed significant difference from those of the other areas.

The ecotoxicity test method using Undaria pinnatifida spore is challenging to use throughout the year. Since U. pinnatifida female gametophytes can be cultured in the laboratory, they can be used for ecotoxicity testing at any time. Changes in female gametophyte survival rate and relative growth rate in U. pinnatifida exposed to various environmental conditions were analyzed. The female gametophyte of U. pinnatifida was exposed to salinity (5~40 psu), temperature (5~30℃), pH (4~10), and light intensity (0~120 μmol photon m^-2 s^-1). Based on the highest average value, the survival rate of female gametophyte was highest at a temperature of 20℃, salinity 27.5 psu, pH 8, and light intensity 30 μmol photon m^-2 s^-1. And the relative growth rate was highest at a temperature of 15℃, salinity 35 psu, pH 9, and light intensity of 60 μmol photon m^-2 s^-1. As a result of this study, the method using the optimal conditions for the survival rate and relative growth rate is expected to be a practical test method that can complement the current method.

The total length, head length, head height, eye diameter, retina thickness, and lens diameter of the dotted gizzard shad, Konosirus punctatus, showed positive allometric relationships between hatching and 30 days post-hatching (dph). The increase in total length relative to head length and head height, head length growth relative to eye and lens diameter, head height growth relative to eye diameter and lens diameter, and thickness of the retina relative to eye diameter, lens diameter, head length, and head height were showed allometric relationships. The eyes were formed completely at 9 dph. At this age, the eye has a lens, an optic nerve fiber layer, a ganglion cell layer, an inner plexiform layer, an inner nuclear layer, an outer plexiform layer, an outer nuclear layer, an outer limiting membrane, a rod and cone layer, and an epithelial layer. The essential demands that must be met by the retina in this species pertain to light sensitivity and spatial resolution.
