This study was conducted to examine the effect of emulsifiers on the quality characteristics of Yackwa. Lecithin and various sucrose fatty acid esters (S-570, S-970, S-1570) were used as emulsifiers. The addition of emulsifiers to Yackwa decreased the hardness, cohesiveness, springiness and gumminess, but increased the brittleness. This tendency was most distinct by the addition of S-970. All sensory characteristics of Yackwa such as color, smooth surface, smell, internal layer formation, softness and overall quality, were improved greatly by the addition of emulsifiers. As a result, the mechanical and sensory characteristics of Yackwa were improved by the addition of the emulsifiers, and sucrose fatty acid esters showed better results than lecithin.

The present study has been conducted to reduce the cold air drying rate. According to the cold air drying method, the quality-excellent product could be made and there would be little change of color, taste and smell. As compared with the hot air drying, the cold air drying equipment has the superior dehumidification in a constant drying zone. However, in a falling drying zone that equipment is not energy-efficient because the drying period could be longer by the dehumidificated.

The quality of cut tobacco will be deteriorated due to weather conditions such as temperature and relative humidity, when shipping and long term storaging. The change of equilibrium moisture contents in cut tobacco were under influence of relative humidity and temperature but not humectants. Therefore internal packing materials are necessary for cut tobacco to maintain initial quality, including taste, flavour and musty smell during shipping or storaging. When packing cut tobacco for shipping or long term storaging, desiralbe packing density was 200/$m^2$, For the long term storage under R.H 90% and 3$0^{\circ}C$, polyethylene film thickness suitable for packing material are above 100$\mu$, which resulted in 42days of shelf life.

This study is to investigate residents' living satisfaction with high-rise mixed-use apartment complexes built in the structures of the reinforced concrete constructing and the steel framed reinforced concrete construction. The results of this study were obtained as follows: 1. Residents expressed below average satisfaction (below 3.0) with the common-area landscape and environmentally-friendly factors, children's playground and its facilities, community service for residents' by the management offices and the plan of utility. 2.According to the satisfaction of sound environment, residents of SRC group expressed above average satisfaction; it can be concluded that problems of causing noise around the residential area of the SRC and S groups were well solved in this study. However, satisfaction with the freshness of indoor air, humidity, and smell in the living quarters was rated low by the residents of SRC group. 3. High-rise mixed-use apartment complexes should accomodate families's life cycle, design an environmentally-friendly resting place in harmony with city life, and provide various communal programs for residents.

A model was proposed for investigating the particle removal from suspension with particles of different sizes by deep-bed filtration, and the collection efficiency was predicted by computer simulation. Deposited particles on the pore surface may act as additional collector and reduce the pore size, which contribute to the improved collection efficiency with increase of deposition. Computer experiments for suspension of particles of three sizes and its equivalent size of mono particles were carried out and compared. The collection efficiency of suspension with poly-dispersed particles shows higher efficiency than that of suspension with mono-dispersed particles. Also the collection efficiency of smell particle of mixture is higher that that of same uniform size particles.

The experiment was conducted to investigate the feasibility of using vegetable oil and non-fat dry milk (powdered milk) with skim milk for the preparation of dahi. In this experiment, six different types of dahi were prepared from whole milk, skim milk and admixture of non-fat dry milk with different levels of vegetable oil. The prepared dahi samples were subjected to physical, chemical and microbiological analysis to evaluate their quality. It was observed that the addition of non-fat dry milk and vegetable oil with skim milk improve the physical qualities (smell and taste, body and consistency, color and texture) of prepared dahi samples. Addition of non-fat dry milk and vegetable oil also improve the total solids, fat and protein content of dahi samples. It is concluded that the addition of vegetable oil at a rate of 4 to 6% together with 5% non-fat dry milk gave the best result.

Ventures through technological innovation are increasingly suggested as one of the main engines for economic growth that can help control inflation and black trade balance. The Purpose of this study is to extract the network performance factors for ventures according to ventures life cycle. For the Purpose, the existing studies were examined into start-up company, entrepreneurial firm, smell firms with competitive advantage against large firms, and ventures network activity. And 63 samples from ventures in Korea were taken and analyzed empirically. The analyses and results are (1) the actual conditions of network activity on ventures; (2) the investigation of relationship between network activity and performance of ventures by venture's life cycle through the observations of Korean ventures. From the results, It Is also found that factors such as external environment and a ventures life cycle have been considered as the main influences on the performance of ventures. In addition, limitations and suggestions for further studies are noted.

최근 소프트웨어 시장의 규모와 위상은 급속도로 성장하고 있다. 하지만 커지는 산업에 비해서 소프트웨어의 품질에 대한 인식은 아직 미흡하다. 국내 중소기업의 경우 인력, 비용 등의 여러 측면에서 어려움이 존재한다. 구현 중심의 개발이 이루어지면서 소프트웨어의 품질보다 빠른 개발에 초점을 두어 저 품질의 소프트웨어를 양산하고 있다. 본 논문에서는 이를 해결하기 위한 가시화를 통해 나쁜 코딩 습관을 개선하여 소프트웨어의 품질향상을 도모한다. 가시화를 통해 소스 코드에서 개선되어야 할 부분을 찾아내 소프트웨어의 품질을 향상시킬 수 있을 것으로 기대한다.

We confirmed the character impact compounds of the flavors of the soybean paste manufactured with the traditional and improved Meju, respectively, by using the following methods: gas chromatography (GC), sniffing tests and GC-mass. The soybean paste made with the traditional Meju had 12 compound groups that smelled like the soybean paste flavor, whereas the soybean paste made with the improved Meju had 7 compound groups of soybean paste flavor smell. We were easily able to determine that there is a difference of soybean paste flavor compounds between the soybean pastes made with either the traditional or the improved Mejus because the two soybean paste flavors are very different from each other.

For the while, food wastes have been mainly gathered in a trash place in outskirt of Seoul to bury under the ground. Recently the residents near the area strongly refused to fetch those food wastes to their area because of the terribly bad smell. According to the statistic, the food wastes have around $30\%$ portion of total living wastes, which are more than other countries. Most of the food wastes have been simply buried or incinerated without deep consideration of resource recovery view. Such burying or incineration makes problem to the residents' life condition. So the first is to reduce as much as possible and the rest should be controlled to reuse as resources.
