On maturation of abalone KIKUCHI'S concept of accumulative temperature expressed ${\Sigma}(t_i-{\theta})$ have been apply importantly for an anniversary spawning of the animals. In case of Haliotis discus hannai he was formulated ${\Sigma}(t_i-7.6)>1300$. This expression is able to modify by UKI'S the relationship between the daily feeding rate ($\%$) (Y) ana temperature ($^{\circ}C$) (t) expressed Y= 0.4291 t-0.1501. The modified expression is as the formula ${\Sigma}(Y-3.05)>570$. And the concept its meaning involves is replaced with accumulative ingestion instead of accumulative temperature. This modified concept is understood that on maturation of abalone temperature decide on satiation level, food ingestion decide on gonad maturity rate.

The Nilsson model was used to predict energy levels of $^{53}$ Mn without taking band mixing into consideration. The results were compared with the experimental levels and the predictions with band mixing of Malik ana Scholz. In both cases, with band mixing and without band mixing, the theoretical fit to experimental results is fair only for a few low-tying levels. However, it is found that the present calculation fits rather better to experiment than the band mixing calculation as far as higher levels are concerned.

The purpose of this study was to identfy the relationship between the body image adjustment of daily life. 58 subjects who had undergone radical mastectomy or modified radical mastectomy from 1979 to April 1984 at Seoul National University Hospital were selected as a sample and used for a final analysis. Finding of this study were as follows; 1) The relationship between the body image and the adjustment of daily life were significant differences. The body image is more positive, the adjustment of daily life is bet-ter. However, the cause-effect relationship was not found in this study. (p<0.05) 2) There were no significant differences in the body image between the right side mastectomy and left side mastectomy, between the radical mastectomy and modified radical mastectomy between those who had occupation and those who did not have occupation, and between the level of education. 3) There was no significant correlation between the body image and age, between the body image and elapsed time after surgery.

Design optimization of a transonic compressor rotor (NASA rotor 37) using response surface method and three-dimensional Navier-Stokes analysis has been carried out in this work. Baldwin-Lomax turbulence model was used in the flow analysis. Three design variables were selected to optimize the stacking line of the blade. Data points for response evaluations were selected by D-optimal design, and linear programming method was used for the optimization on the response surface. As a main result of the optimization, adiabatic efficiency was successfully improved. Ana, it is found that the design process provides reliable design of a turbomachinery blade with reasonable computing time.

For the improvement of productivity of Pleurotus ostreatus, the production of liquid spawn was studied. The highest liquid spawn production was obtained after shaking culture for 4 days in the culture medium containing 5%(W/V) wheat flour, 0.2%(W/V) yeast extract, 0.1%(W/V)$KNO_3$ 0.05% (W/V) $MgSO_4{\cdot}7H_2O$, 0.05%(W/V) $KH_2PO_4$. The optimum pH and temperature was 7.0 ana $30^{\circ}C$. The period required to complete the mycelial growth after spawning were 28, 22, 10 and 9 days, respectively, when the 2%(V/V) of solid spawn and 2%(V/V), 5% (V/V) and 10%(V/V) of liquid spawn were inoculated. The days required from spawning to fruiting bodies were 38, 34, 28 and 27 days.

This paper has provided a systematic technique, the evaluation of the distribution with the NPV ana the derivation of the IRR in the investment alternatives, for the cost estimating analysts. The proposals of investment alternatives are included the venture capital under risk and probabilities at each events, within the cash inflows are occuring at random timing. Therefore. we have considered the followings : 1) the first cash outflow is deterministic. 2) the cash inflows are random variables with known distributions. 3) the lengths of the time intervals between the cash inflows are independently distributed and independent of the cash inflows. In this paper. the first two moments of the distribution, the Laplace Transforms and the convolutions are computed for both independent cash inflows and mutually exclusive alternatives as in the case of quite correlated cash inflows.

The purpose of this study was to investigate the relationship between three aspects of clothing behavior ana three personality traits. Personality traits were measured with Chung's Personality Scale. 1 The questionnaire measuring clothing behavior consisted of items designed to assess clothing conformity, importance, and self-concept regarding clothing, This questionnaire was composed of items designed for this study in addition to items selected from questionnaires of such researchers as Sin, Lee, Chung, creekmore, Cheek, and Kim. These questionnaires were administered to 323 high school girls in Seoul. Statistical analysis consisted of correlation and t-test. The results were : 1) Dominance was positively related to self-concept regarding clothing and negatively related to clothing conformity. 2) Emotional stability was positively related to clothing modesty. 3) Sociability was positively related to self-concept regarding clothing. 4) There was no significant difference in clothing behavior between early adolescents and late adolescents.

The purpose of this study was to see if a relationship existed between the level of modesty in clothing ana clothing values of male and female university students. The difference between sex was also investigated. A questionnaire composed of Engelbrecht's 'Modesty in relation to women's dress' and Creekmore's 'Measure of eight clothing values' was administerd to 1, 100 students and the data from 888 respondents (466 male, 422 female) was analyzed by t-tests. findings were as follows : 1. There was no significant difference between male and female in the level of modesty in clothing. 2. Each score of sensory, economic. social, theoretical, and religious clothing value of male students was significantly high and exploratory, aesthetic and politicalclothing value score of female students was significantly high at the .005 level of confidence. 3. Each score of sensory economic, theoretical and religious clothing value was significantly high in Modest group and exploratory, aesthetic and political clothing value in Immodest group was significantly high at .005 level of confidence.

This paper presents the temperature distribution of the oil-immersed self-cooled transformer with radiator performed by coupled magneto-fluid-thermal analysis. Particularly, 3D temperature distribution of cooling oil and sub-components under the natural convection is obtained by computational fluid dynamics analysis, while heat sources are predetermined by magnetic field analysis using F.E.M. The predicted temperature distribution of the power transformer model is compared with the measured data for verifying the validity of the proposed analysis.

Sperminogen was purified from the acid extracts of boar spermatozoa and partial peptide sequence of the 34-36 kd sperminogen was determined. Acid extracts of boar spermatozoa was gel-filtered through Sephadex G-75, and the 34-36 kd sperminogen was purified by preparative SDS-PAGE. The sperminogen bands were sliced out, and 34-36 kd sperminogen were eluted from the gel fragments and was subjected to peptide sequencing. Since the amino termini were blocked for Edman degradation method, internal amino acid sequences of the eluted 34-36 kd sperminogen were obtained from CNBr-digested peptides of sperminogen. Among several bands resolved on tricine SDS-PAGE, 14, 22 and 26 kd peptides were subjected to peptide sequencing. The ana1yzed amino acid sequences of the 26 and 22 kd peptides showed high homologies with that of the zona pellucida binding protein, Sp38, and the analyzed amino acid sequence of the 14 kd peptide showed neither sequence homology nor similarity with any known proteins.
