尹燾善 최신의학사 1973 最新醫學 Vol.16 No.10

There are distinct differences of .voices between the male and female human beings but it is to be proved whether there is any sexual difference' among the infants crying sounds. "baby is not a miniature of adult" is a maxim of pediatrics. If the result of the experiment of the author showed there is. not sexual difference, it will be another, confirmation for the "maxim". In the adults there are differences in voice between the sexes and supposing there is no sexual difference among the babies, then at what stage of growth, the transition takes place, and it will be an interesting matter for a study, As for the material for the study the babies delivered at the Seoul National University Hospital were used. Within 24 hours after delivery they were made cry by pinching the check and the sounds were recorded on a tape and the oscillations were examined. The measurement of the oscillation number was carried out by the CATHODE-RAY OSILLOCOPE, and contrasting the unknown oscillation number with a known standard oscillator, the pictures of the shape of the waves were simultaneous taken and the wave lengths and its number were compared. Among the new-born infants, studied 23 male and 17 female babies as indicated in Table I, the distribution of the oscillation types are shown in Figure 3. As shown in Figure 3, the absence of normal distribution is due apparently to. lack of the number of cases studied: The mode was 1, 400 c/s. The total mean value for both sexes was 1, 997 c/s and for the male 1, 994 c/s and or the female 2, 000 c/s. Therefore, there was not much difference between the sexes.

고장원인이 여럿인 수리불가능한 제품에 대하여 사용환경에서 얻어진 고장데이터와 추적조사에 의해 얻어진 설명변수에 관한 데이터를 이용하여 제품의 고장원인별 수명분포를 추정한 배도선 등(1995)의 연구를 수리가능한 제품의 경우로 확장하였다. 수명분포의 모수와 설명변수가 대수선형 관계일 때 비동질성 포아송과정을 이용하여 의사우도함수를 유도하고, 고장원인별 수명이 와이블 분포를 따를 때의 의사 최우추정량과 점근분산을 구하였다. 추적조사 방법으로는 보증기간동안 고장이 발생하지 않은 제품의 일정비율을 추적조사하는 경우와 총 시험제품의 일정비율을 랜덤하게 선택하고 이들 중에서 보증기간동안 한번도 고장이 발생하지 않은 제품에 대해서만 추적조사하는 경우를 고려하였다. This paper is concerned with the method of estimating lifetime distribution from field data for repairable products with multiple modes of failure, and is an extension of Bai et al.(1995). The log linear function is considered as a model for describing the relation between failure time of a product and covariates. Using the nonhomogeneous poisson process, general methods for obtaining pseudo maximum likelihood estimators(PMLEs) for the parameters are outlined and specific formulas for Weibull distribution are obtained. Effects of follow-up percentage on the PMLEs are investigated. Extension to case-cohort design is also considered.

The characteristic and change of dwelling architecture of Japanese and plot transition were analyzed with the old international settlement in Gunsan. By learning about one side of modern history that was broken off in the historical form of dwelling and observing the dwelling environment that have been changing historically, it can be significant as the basic material of observing our dwelling today. Along with prior investigations and studies related to the late 19th century (opening of port period) urban dwellings, the urban tissue was analyzed through documents about the history of Gunsan city and other cities that were occupied by Japan. In addition, along with survey investigation based on the cadastral map, construction management register and aerial map, I also worked on drawing up dwellings and urban tissue. As for the time range, the urban tissue of Gunsan, before opening of port, and after opening of port from 1899 to 1945 during the Japanese Occupation, was studied. And, the urban tissue was studied up to the current 2002, where the plot transition is changing or continuously maintained. As for the district subjected for study, the established international settlement district of Gunsan during the early stage of opening of port, was established as spacial range, focusing on Yeonghwa-dong which was the center of international settlement district, which was abolished in 1913. This was the first district in Gunsan to be planned with grid streets structure, and this could be said to be the main dwelling that keeps the characteristic of Japanese dwellings. The old international settlement of Gunsan has become the center of urban tissue development of the current Gunsan, and the initially established street pattern influenced the form and plot of dwellings. The dwellings have been changing with correlation to the current plot. As the plot line is fixed according to the line divided within a long building(長屋), the form is changed through a small scale of subdivided plots combining, in the process of new construction by removing the existing structures again. The plot is changing of possessing one-way improvement only by facing the street, as the bare grounds (alleyway) disappeared. The dwellings in this district, long buildings or machiyas(町屋), have developed with precedent pattern according to the street, and the dwellings have developed in the direction of inner household. In addition, as for the dwelling space, there was change in the use and extension, due to the factors such as difference in style, change in life style and modernization of accommodation system.

Some effect on the absorption rates of each nutrient, and Ca and P metabolism in growing albino rats by feeding on rice diet mixed with serveral species of wheat and barley have been studied. The growing rats were fed on the control diet and 10%, 30% or 50% wheat and barley mixed with rice diets for 1, 4 and 8 weeks. The species of wheat and barley used in this expeiment were the wheat, the naked barly (Baik-dong and Cheong-maik) and the barley (Su-won No. 18 and Je-cheun No. 5). The absorption rates of protein, fat, carbohydrate, cslciuum and phosphorus have been measured. The results obtained are summarized as follows: 1. The protein absorption rates of each wheat and barley mixed with rice diet group were similar t o that of the control group. 2. The nitrogen retentions showed a tendency to decrease in the wheat, the Baik-dong, and the Su won mixed with rice diet groups in early stage, compared with the control diet group. But those were similar to that in the control diet group, fed for 8 weeks. 3. The nitrogen retentions of the Cheong-maik, and the Je-cheun mixed with rice diet group were higher in the 50% than that of the 10% mixed diet group. 4. The fat absorption rates of the wheat, the Baik-dong and the Su-won mixed with rice diet group were generally lower in the 50% than that of the 10% mixed diet group. 5. The carbohydrate absorption rates and calory utilization rates in each diet group were no remarkable change for each term with each diet group. 6. The calcium absorption rates of the wheat mixed with rice diet group was lower than that of the control diet group, fed for 1 week. But those of the other mixed diet group showed the similar tendency t o each other. 7. The phosphorus absorption rates of the Baik-dong and the Cheong-maik mixed with rice diet group, were lower in the 50% than that of the 10% mixed diet group fed for 4 and 8 weeks. 8. In the muscle, the phosphorus contents was no remarkable change with each mixed diet group, where as the phosphorus and the calcium contents in the bane were apt to increase gradually by feeding on each term. In the view of the above results, it could be seen that digestion and absorption rates of each nutrient, even in the condition of a lot of each nutrient absorbed, was not greatly effected by the species or mixed ratio of wheat and barley in the growing albino rats.

The activity of GOT and GPT in the liver and serum of the rats that were fed mixed diets which were different mixed rate between rice and barley or wheat were observed. The experimental animals, albino rats weghting 100-120gm were fed on rice diet mixed of barley and wheat in 10%, 30% and 50%. Experimental term was devided into for 4,8 and 12 weeks. The results obtained are summarized as follow: 1. The activity of GOT and GPT in the liver and serum have shown some similartendency among the diet mixed rate and diet groups. 2. The activity of GOT and GPT in the liver and serum have shown remakable change according to each feeding term.
