A Model of small scale total mixed rations(TMR) plant which can be utilized round bales was developed, tested and analyzed in this study. This study consist of two parts. One is development of a small scale TMR plant model which was already reported at the previous paper. This is the second part of the study. For the study, a series of tests of the model plant were performed and its costs was analyzed. Also, the break-even point of the model plant by comparing with market price of commercial TMR feed was determined. Results of the research are summarized as follows ; As the results of mixing test, the average coefficient of variation(CV) value for mixing of the feed was 13.0 % at the gate of the mixer. The production cost was estimated as 8,298 won/head for dairy cattle farm and 2,495 won/head for beef cattle farm, when producing 8 batch a day. Also, it is recommended to utilize the model plant when farm size is over 79 heads for dairy cattle farm and 113 heads for beef cattle farm. As an overall conclusion, the model plant designed for farm size TMR feed mill will be very useful model for both beef cattle and dairy farms in Korea. Also it is expected that the capital investment for the model plant can be recovered with 8 months compare with purchasing commercial TMR feed if the model plant feeds 1,000 beef cattle approximately.

We develop a time-temperature indicator (TTI) that can determine whether thawing of fish and other fishery products has occurred during frozen storage. A polypropylene tube with an internal diameter of 3 mm was prepared and cut to a length of 14 to 20 mm. One end of the tube was thermally sealed and 0.1% acetic acid was injected into the other end; the tube was then frozen at $20^{\circ}C$. Then the open side of the frozen tube was blocked by sinking the tube into a 10% gelatin solution. The tube was attached to a polyvinyl packaging bag along blue litmus paper and the bag was put into a freezer at $-20^{\circ}C$. After freezing, the bag was removed to an ambient temperature of $20^{\circ}C$, and the time dependence of the color change of the litmus paper was observed. The color changed from blue to red, with the length of the red region increasing with time. Our TTI can be used as a part of a visible detection system and the detection program can conduct the elapsed time analysis on the length of the red region of the litmus paper indicating the degree of thawing. Thus, the TTI is a useful tool in the temperature management of frozen fish and fishery products.

Objectives: The purpose of this study was to characterize the effect of the fraction of Korean mountain ginseng folium (FKG) on the learning and memory impairments induced by scopolamine. Methods: The memory ameliorating effect of FKG was investigated using a passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by treating animals with scopolamine(1mg/kg, i.p.). Results: FKG (2 or 4mg/kg, p.o.) administration significantly reversed scopolamine-induced cognitive impairments in mice by the passive avoidance test and the Y-maze test(P<0.05), and also improved escape latency in the Morris water maze test at 2 or 4mg/kg(P<0.05). Although FKG has little inhibitory activity for AChE (IC50 value; 1847 ${\mu}g/ml$) in an invitro study, phosphorylated extracellular signal-regulated kinase(pERK) was increased by the administration of FKG inhippocampus on immunohistochemistry. Conclusions: These results suggest that FKG may be a useful cognitive impairment treatment, and its beneficial effects are mediated, in part, via activation of ERK pathway.

Nipple reconstruction is an important step in breast reconstruction after mastectomy. The authors' preferred reconstructive technique is the local C-V flap in case that a small opposite nipple is not adequate for composite graft. This flap produces an excellent reconstruction, but it is not easy to produce an adequate projection and firmness of the nipple. This article describes the technique and experience in nine patients treated over two years with dermis(scar tissue) graft for nipple reconstruction. This is the first report of application of autologous dermis(scar tissue) grafting to reconstruct a nipple primarily after breast mound reconstruction, decreasing the absorption of the reconstructed nipple and increasing the hardness. The dermis(scar tissue) is taken from scar revision and/or dog-ear correction in the second stage operation after free TRAM flap breast reconstruction. And the dermis(scar tissue) graft is inserted vertically between the local flaps and horizontally under the reconstructed nipple base. Between September 2002 and February 2005, nine patients underwent C-V flap with dermis(scar tissue) graft as a part of their nipple reconstruction. The patient's ages ranged from 28 to 55 years old (mean, 41.1 years old). The follow-up period ranged from 5 to 35 months, with an average of 14.5 months. None of the nipples showed skin flap necrosis or local infection, and uneventful wound healing. Our result showed good nipple projection with less absorption and enough firmness. Our experiences shows that dermis(scar tissue) grafts in C-V flap is a very useful method for nipple reconstruction.

The purpose of this study was to improve the fitness of Korean manufactured apparel products being exported to China and to provide for the basic data useful to the development of a torso prototypes for the Chinese women. For this purpose, Chinese college women aged between 18 and 24 were sampled to test the fitness of the Korean manufactured apparels for the Chinese women sample and address the problems of unfitness and thereupon. The results of this study can be summarized as follows; As a result of testing the fitness of the Korean manufactured apparels for the Chinese women, it was found that Chinese women felt more or less comfortable for the front of the jackets, but felt less comfortable with their side and back. Such a finding suggests that the Chinese women's postures are more turned back than the Korean women's. And also for the slacks, lack of a crotch length causes unnecessary pulls and creases from the back part to the crotch of a pair of slacks and the side line was not suitably placed. For this reason, the differences between the body shapes of Chinese and Korean women should be thoroughly considered when drawing the patterns to export to China.

The purpose of this study is to examine modern people's lifestyle and identify their needs by analyzing clothing behavior through city nomads' attitudes in dairy life, tastes, and methods to pursue in their life. This study tries to understand substitute values as ethical life emerging recently, free life style of mental emotion, clothing behaviors, and fashion style represented by the results. Upon observing city nomads' fashion trend, tunics symbolizing flexibility and comfort and simultaneously reflect colors in a monk style or from basic items that have been used. City nomads' fashion trend also reveals androgynous freeness-and-easiness. City nomads reflect a folksy inspiration, and different cultural perspectives appear in a mixed fashion. Multi-purpose gypsy/boho style is ideal for traveling and occupying smaller spaces in line with the nomadic lifestyle reflectings an American casual image partially by way of gypsy or bohemian nuances. Motorcycle jeans symbolizing functionality for traveling are becoming a part of everyday life. The fashions discussed are categorized as urban, tourer, sports and road. Everyday sportswear - athleisure - is attracting attention enabling a healthy and sound lifestyle. Athleisure is fashion wear harmonizing workplace with leisure, and everyday life and social gatherings. Athleisure represents a significant collapse of the boundary of high fashion and street fashion. Urban- tech wear is light and enables modern people to perform garment and gear functions simultaneously, making storage useful using various technical devices by elevating activity and functionality. Urban outdoor fashion holding functionality and adding modern fashion in appearance has appeared.

Colorectal carcinoma is occurred frequently to Korean and so ranked the fourth from various cancers. Due to western dietary life, this cancer has been increased continually. Therefore, the study will be needed to find a candidate gene involved in the development and progression of colorectal carcinoma and to diagnose and treatment helpfully. The striking feature from cancer suppressor genes is known for LOH (loss of heterozygosity), which is the method to find allele genetic loss or mutation of cancer cell. The purpose of this study was designed to find a carcinogenic gene from colon cancer using microsatellite marker on 17th and 18th chromosome from 30 subjects. The LOH was investigated in order of D18S59 57% (17/30), TP53CA 50% (15/30), D18S68 47% (14/30), D18S69 43% (13/30). The genetic mutation depends on loci of colorectal carcinoma was shown higher with 2.44 from colon cancer than with 1.25 from right colorectal carcinoma (p<0.032). The genetic mutation with lymph nodes was investigated higher with 2.69 at mutated group than with 1.14 at non-mutated group (p<0.003). At genetic mutated pattern depends on disease stage, there was higher significant difference at III-IV stage 2.50 than that of I-II stage 1.17, respectively (p=0.015). There was no difference at comparison between histological classification and serological CEA increase. The loss on 18q21 found in this study is highly recurrence loci and was observed 43% for Korean with high recurrence. Therefore, LOH is a very useful tool to detect 18q21 loci in clinical application, prior to the treatment of colorectal carcinoma. After the operation of colorectol carcinoma, the efficient application using LOH at operated part tissue which is designed to protect the recurrence as well as its cure will be needed.

In this research, consumer awareness investigation and wearing test were carried out for obtaining useful data on the development of thermo-sensitive functional clothing material. A survey involved 216 people in Seoul and Kyeonggi-do, and 200 questionnaires data were analyzed by descriptive statistics and frequency using SPSS 17.0. Four healthy men in twenties were participated for wearing test. Subjects in normal loungewear were exposed to temperature change from the initial temperature $30^{\circ}C$ down to $5^{\circ}C$ for an hour in a climate chamber. The environmental temperature, surface temperature of garment and skin were measured. As a result, most of respondents have all season clothing products such as underwear, hosiery, and jogging suit for loungewear. Also, thermo regulator y functional clothes are frequently used as underwear and sweat shirt. The consumer awareness investigation on thermo regulatory functional clothing showed that the most important key buying factor is quick climate temperature response, easy maintenance, design and cost, in that order. Surface temperature of garment went down with the cooling down of environmental temperature. The lower environmental temperature, the greater temperature difference by body part showed. Skin temperature change by environmental temperature showed similar tendency of garment surface temperature. In comparison between garment surface and body skin, temperature difference became larger under the lower environmental temperature.
