The purpose of this study is to research on status of physical discomfort and clothing life including clothing inconvenience for enhancing self-reliance of elderly women, newly emerging consumer. The subject of research were 346 elderly women who aged 60 or older in Seoul and Seoul Suburbs. Survey consisted of questions about body discomfort, satisfaction and purchasing criteria of ready-to-wear, the inconvenience of clothing. The results of this study are as follows: Physical discomforts were generally associated with the ability to regulate body temperature. The biggest complaint of ready-to-wear was the price, and the next were the size and activity. In purchasing criteria, 'clothes to fit my body shape', 'clothes easy to put on and take off', 'comfortable clothes to work' showed high score. In clothing inconvenience, 'feel inconvenience due to several layers of clothing to avoid chilliness', 'feel heaviness in the waist due to tightness', 'feel chilliness even when wearing several layers of clothing in the winter' were the most uncomfortable parts. Subjects over the age of 80 years and needed the help of others in activities experienced more inconvenience in clothing life. It seems that body discomfort such as dulness of movement and loss of body temperature regulation capability due to aging had a influence on their clothing life. This problem could be improved by the adjustment of pattern allowance, the selection of the fastener, and the proper use of functional fabric. The results of this study will be used as a basis for development of the elderly women's clothing to increase convenience and mobility in everyday life.

This study was conducted to compare the perception and fast food usage patterns of adults classified by age in Busan. The survey was conducted from April 15 to June 15, 2017 by questionnaires and the data were analyzed using SPSS 24.0 Overall, 74.1%, 58.1%, 40.7%, 20.3%, 29.7% and 17.9% of individuals in their 20s, 30s, 40s, 50s, 60s and 70s, respectively, consumed fast foods more than once a week. Additionally, 66.0%, 52.5%, 25.7%, 16.0%, 22.9% and 11.7% of individuals in their 20s, 30s, 40s, 50s, 60s, and 70s, respectively, preferred fast foods. There was a significant difference in the basis for choosing menu among the groups, with 'preference' and 'price' being most important to those in their 20s and 30s, on the other hand 'preference' and 'companion' being most important to members of other age groups. As their age increased, individuals spent less money on fast food. Overall, 81.5%, 59.9%, 50.0%, 40.1%, 46.3%, and 28.4% of individuals in their 20s, 30s, 40s, 50s, 60s and 70s thought that fast food was a suitable substitute for a meal. Age affected the substitutability of fast food for a meal (P<0.001). Additionally, the ratio of individuals in their 20s and 30s that skipped breakfast was higher than in other age groups. In addition, age showed a significant positive correlation with obesity and dietary attitude, whereas it showed a negative correlation with nutrition knowledge, use frequency, perception degree and preference. Nutrition knowledge and dietary attitude showed no relationship with preference. These results imply that a nutrition education program should be developed and conducted to induce subjects to manage their dietary habit and develop healthier dietary patterns.

We have built a near-infrared imaging camera with a PtSi array detector manufactured by the Mitsubishi Company. The PtSi detector is sensitive in the wavelength range 1 to $5{\mu}m$. Quantum efficiency of PtSi is much lower than that of InSb and HgCdTe types. However, the PtSi array has advantages over the latter ones: (i)The read-out noise is very low; (ii)the characteristics of the array elements arc uniform and stable; (iii)it is not difficult to make a large PtSi array; and (iv) consequently the price is affordably low. The array used consists of $512{\times}512$ pixels and its size is $10.2\;mm{\times}13.3\;mm$. The filter wheel of the camera is equipped with J, H, K filters, and an aluminum plate for measuring the dark noise. The dewar is cooled with liquid nitrogen. We have adopted a method of installing the clock pattern and the observing softwares in the RAM, which Gill he easily used for other systems. We have developed a software with a pull-down menu for operating the camera and data acquisition. The camera has been tested by observing $\delta$ Orionis.

Lee[15] examined quantity discount contracts between a manufacturer and a retailer in a stochastic, two-period inventory model where quantity discounts are provided based on the previous order size. During the two periods, the retailer faces stochastic (truncated Poisson distributed) demands and he/she places orders to meet the demands. The manufacturer provides for the retailer a price discount for the second period order if its quantity exceeds the first period order quantity. In this paper we extend the above two-period model to a k-period one (where k < 2) and propose a stochastic nonlinear mixed binary integer program for it. In order to make the program tractable, the nonlinear term involving the sum of truncated Poisson cumulative probability function values over a certain range of demand is approximated by an i-interval piecewise linear function. With the value of i selected and fixed, the piecewise linear function is determined using an evolutionary algorithm where its fitness to the original nonlinear term is maximized. The resulting piecewise linear mixed binary integer program is then transformed to a mixed binary integer linear program. With the k-period model developed, we suggest a solution procedure of receding horizon control style to solve n-period (n < k) order decision problems. We implement Lee's two-period model and the proposed k-period model for the use in receding horizon control style to solve n-period order decision problems, and compare between the two models in terms of the pattern of order quantities and the total profits. Our computational study shows that the proposed model is superior to the two-period model with respect to the total profits, and that order quantities from the proposed model have higher fluctuations over periods.

고압으로 수송되는 천연가스를 수요처에 공급하는 정압기지에서는 강제로 감압하여 보내준다. 이 때, 버려지는 압력에너지를 회수하는 방법으로 터보팽창기를 이용한 전력생산이 가능하며, 터보팽창기는 정압과 전력생산의 두 가지 기능을 동시에 수행하게 된다. 터보팽창기에서 생산되는 전력의 양은 유동전후의 엔탈피 차이며, 경제성에 영향을 미치는 주요인자로는 설비비, 전력생산량, 예열량, 전력가격, 가스가격의 5가지이다. 입구와 출구의 압력과 온도 조건이 고정되므로, 전력생산량은 결국 유량에 좌우된다. 따라서, 천연가스 수요의 계절별 수급변화 패턴에 따른 터보팽창기 적정용량을 결정하는 것이 경제성확보의 핵심기술이다. 유동량변화가 심한 경우의 전력생산량 산정법의 algorithm을 제시하였으며 이를 사용한 case study를 수행하였다.

Interests in the field of rapid methods and automation in microbiology have been growing steadily on an international scale in recent years. International meetings concerned this problem have been held in elsewhere in the world countries since the past twenty years. But, unfortunately in the field of microbial examination in food hygiene, this problem have not yet been developed so much as in the field of clinical microbiology. Today, I would like to introduce you here present aspects of rapid and automation technologies, those which are manly carrying in milk and meats industries. My illustration will be given recent improved technologies using automatic apparatus and instruments along with process of microbial count procedure. Recent direct microbiological counting system (ChemeScan \ulcorner) as real time ultrasensitive analysis created by Cheminex Ltd., France is now most evolutional instrument to provide direct microbial counts, down to one cell, within 30 minutes. The results from these evaluations how a good correlation between the ChemScan system and the standard plate count method. This system will be successful application for not only in the field of pharmacology but also food microbiology. In addition, current identification of microbes by sophisticated instruments suitable for food microbiology, one of which Biology is manual system (BIOLOG\ulcorner), provides reference-level capability at a modes price. For the manual system, the color reactions in the microplate are read by eye and manually keyed into personal computer. Species identification appears on the computer screen within seconds, along with biotype patterns, a list of closely related species, and other useful statistics. In present this is useful application for microbial ecology and epidemiological survey. RiboPrinter system newly produced by DuPont is now focusing among microbiologists in the world, and is one of the biggest microbial characterization system using a DNA-based approach. The technology analyzer is bacterial culture for its genetic fingerprint or riboprint pattern. Finally Bio-cellTracer system for automatic measurement of fungal growth and Fukitori-Maseter, a Surface Hygiene Monitoring Kit by using swabe procedure in food processing environment are briefly illustrated in this presentation.

This study was conducted to develop the standard breakfast menu for those weak groups having insufficient breakfast intake. The following three target groups are classified as: 16-19 years old high school male student, 20-29 years old female who have job or college students, 20-29 years old male or female who have job (double income family). While developing menus for each target groups, we applied several basic guidelines for meal planning as follows: Nutrient intake level was set to $\graction one-Third$ of RDA, while the energy level to $\fraction one-quarter $ of RDAs. Most Sequent meal pattern of Koreans was adapted; Suitabilities of appropriate serving size and cost for middle-income families were considered; Domestic foods and ingredients were used. We developed 24 menus summed by 2 menus for each season and three target groups. When evaluating the menus, most of the breakfast menus were sufficient of nutrients as a meal for the subjects. Three food groups such as grain/starch group, meat/fish/egg/bean group, vegetable/fruit group were included in all menus. Even though milk/dairy products group was not excluded for some menus, other calcium substitutes like anchovies were used. Oil/nut/sugar group was used to a minimum. The average number of foods for each menu was 12.8, which ranged from 10 to 17 depending on the menus. The average weight of the menus including soup was 822 g, 633 g and 730 g for each target group, respectively. The average price of the menu ranged from 2,000 to 3,500 won per person. The above results could be applied at home as well as foodservice institutes and furthermore could offer information for developing breakfast-substituting food products.

We conducted this study to compare the awareness and attitude of Busan housewives about consuming marine products. The survey was conducted from April 10 to May 31, 2019 by using a questionnaire. The degree of preference of seafood was higher among individuals in their 40s than those in the other age groups. Among the women in their 30s, 40s, 50s and 70s, the reason for liking seafood was 'taste', and for those in their 60s it was 'nutrition'. Overall the most common reason for disliking seafood was the 'fishy smell (37.4%)'. Conception degree of nutritive value of seafood was higher among individuals in their 30s and 40s than that for those individuals in their 50s, 60s and 70s. As for the price of seafood, the wives over 40s thought seafood was more expensive than did those wives in their 30s. The younger the individuals were, the lower was the perceived degree of safety was 49.8% of the subjects reported that the main concern for purchase was 'freshness'. The perceived degree of safety for imported seafood was better for the wives in their 60s and 70s than that for those wives in their 30s, 40s and 50s. The confidence level for local Korean seafood was higher for the wives in their 60s than that for the wives in their 50s. The degree of preference for seafood was moderate overall, except for Jellyfish. Age was positively correlated with conception for safety and dietary attitude (P<0.01), whereas age was negatively correlated with monthly food expenditure, nutrition knowledge and intake requirements (P<0.01). Preference for seafood was positively correlated with conception for safety (P<0.05), nutrition knowledge (P<0.05), dietary attitude (P<0.01), awareness for nutritive value (P<0.01) and intake requirements (P<0.01). Laws and regulations should be reinforced in order to promote eating more seafood and periodic research to determine the actual amount of consumed seafood and people's preferences should be conducted.
