Korea has its long history and tradition of eating dogmeat as food, but dogmeat was excluded from the animal procession law because of the criticism from foreigners, so it is being distributed without inspection of government. Government rejects people's demand for the legalization of edibility of dogmeat due to the protest from a few animal right activist groups, but 80% of nationals favor edibility of dogmeat, and urge the legalization of dogmeat, while 20 lawmakers in legislature submitted the bill to legalize the edibility of dogmeat, and judicature ruled dogmeat is edible meat. Westerners' criticism on dogmeat is, in part, from real protection of animal, but rather their intention seems to be from the racism of colors, the purpose to increase the export amount of beef, to divert the attention of utilizing the abandoned pet dog as animal feed, and to raise a fund for the animal right activist groups. Government distorts the public opinion of edibility of dogmeat, making use of the related animal protection group, and the ministry of Agriculture and Forestry controlling over the animal protection law sides for the concerned groups opposing to the edibility of dogmeat, not for farmers. Furthermore, government has no intention of solving the problem of edibility of dogmeat and can't even propose the solution without presenting any adequate measure, worsening the situation. As a result, the issue of edibility of dogmeat is on the dead angle of sanitation, and wastes of dog slaughtering are polluting the environment. To solve this problem, it is necessary to legalize the edibility of dogmeat in order to distribute it sanitarily, to protect the environment, to increase tax revenues, and to secure the national pride. In addition, the Ministry of Agriculture and Forestry should transfer the jurisdiction over the animal protection law to the Ministry of Environment, and government should execute a reliable policy on the bases of objective and accurate investigation and statistics. Also, it is needed not only to set up the exclusive public bureau to make the edibility of dogmeat known worldwide and research institute, but also to launch the non government organization under the auspices of government. Then dogmeat can become the world renowned food as that of representing Korea.

The objective of this study was to determine the effects of residual nitrite contents, chitosan with different molecular weight and nitrite addition on emulsified sausage during cold storage. Six types of sausages were evaluated: control, 0.5% 50 kDa chitosan (T1), 0.5% 200 kDa chitosan (T2), 150 ppm nitrite (T3), 0.5% 50 kDa chitosan+150 ppm nitrite (T4), and 0.5% 200 kDa chitosan+150 ppm nitrite (T5). Each type of sausage was tested in triplicate and assigned to one of four storage periods: 0, 10, 20 and 30 days. As the storage time increased, the presence of chitosan and nitrite resulted in decreased residual nitrite value and increased pH (in control and T2), TBARS (thiobarbituric acid reactive substance) values, and total plate counts (TPC). Values for pH, TBARS, residual nitrite and total plate counts decreased significantly in response to the addition of chitosan and nitrite relative to the control (p<0.05). T5 was redder than the control (higher CIE$a^*$) at 30 d; however, no difference in the CIE $L^*$ and $b^*$ values was observed. T5 was significantly (p<0.05) more effective at delaying lipid oxidation when compared to the other treatment groups. T5 presented TPC that was significantly lower (p<0.05) than the other groups after three days of storage. In addition, the use of chitosan and nitrite in combination had much better antioxidant and antimicrobial effectiveness than other treatment groups. In conclusion, this study demonstrates that the addition of 0.5% 200 kDa chitosan and 150 ppm nitrite in combination with emulsified sausages tended to improve antioxidative and antimicrobial effects during storage when compared to other treatment groups.

The effects of rosemary and $\alpha$-tocopherol, added individually or in combination, on broiler performance, thiobarbituric acid reactive substance (TBARS), total plate count (TPC) and meat color of chicken thigh meat were investigated. Three hundred broiler chicks divided into five groups were fed a basal diet (control) or basal diet supplemented with 5 g rosemary/kg (T1), 10 g rosemary/kg (T2), 200 mg $\alpha$-tocopherol/kg (T3), or 5 g rosemary/kg + 200 mg $\alpha$-tocopherol/kg (T4) for 5 weeks. Following slaughter, chicken meat was stored at $4^{\circ}C$ for 10 days. All treatments did not influence the performance. Rosemary supplementation delayed lipid oxidation in thigh meat during refrigerated storage. T2 was significantly (p<0.05) more effective in delayed lipid oxidation compared to T1, but was inferior to T3. Samples containing a combination of antioxidant had lower TBARS values than those containing the individual antioxidants, indicating a synergistic effect. TPC was significantly increased (p<0.05) in thigh meat of all groups throughout the refrigerated storage. The T3 and control groups showed TPC counts that did not differ from each other during the entire storage period. However, rosemary supplementation was associated with bacterial counts that were significantly lower (p<0.05) than the control and $\alpha$-tocopherol groups at day 3 of storage and thereafter. For this period, T1 presented TPC counts that were significantly higher than the T2 group (p<0.05). At all storage times, the thigh meat of rosemary-fed chickens was redder than control (higher $a^*$), while no differences in $L^*$ and $b^*$ values were found. A synergistic effect was obtained from the combination of rosemary with $\alpha$-tocopherol, whereas individual use of the antioxidants significantly improved color stability compared to the control.

Electric power which is the energy source of economy and industries requires long distance transportation due to regional difference between its production and consumption, and it is supplied through the multi-loop transmission and distribution system. Prior to its actual use, electric power flows through several transformations by voltage transformers in substations depending on the characteristics of each usage, and a transformer has the structure consisting of the main body, winding wire, insulating oil and bushings. A transformer fire that breaks out in substations entails the primary damage that interrupts the power supply to houses and commercial facilities and causes various safety accidents as well as the secondary economic losses. It is considered that causes of such fire include the leak of insulating oil resulting from the destruction of bottom part of bushings, and the chain reaction of fire due to insulating oil that reaches its ignition point within 1 second. The smoke detector and automatic fire extinguishing system are established in order to minimize fire damage, but a difficulty in securing golden time for extinguishing fire due to delay in the operation of detector and release of gas from the extinguishing system has become a problem. Accordingly, this study was carried out according to needs of active mechanism to prevent the spread of fire and block the leak of insulating oil, in accordance with the importance of securing golden time in extinguishing a fire in its early stage. A bushings fireproof structure was developed by applying the high temperature shape retention materials, which are expanded by flame, and mechanical flame cutoff devices. The bushings fireproof structure was installed on the transformer model produced by applying the actual standards of bushings and flange, and the full scale fire test was carried out. It was confirmed that the bushings fireproof structure operated at accurate position and height within 3 seconds from the flame initiation. It is considered that it could block the spread of flame effectively in the event of actual transformer fire.

The fires in the traditional markets often occur recently with the most of them expanded into great fires so that the damage is very serious. The status of traditional markets handling the distribution for ordinary people is greatly shrunk with the aggressive marketing of the local large companies and the foreign large distribution companies after the overall opening of the local distribution market. Most of the traditional markets have the history and tradition from decades to centuries and have grown steadily with the joys and sorrows of ordinary people and the development of the local economy. The fire developing to the large fire has the characteristics of the problem that the fire possibility is high since all products can be flammable due to the deterioration of facilities, the arbitrary modification of equipment, and the crowding of the goods for sale. Furthermore, most of the stores are petty with their small sizes so that the passage is narrow affecting the passage of pedestrians. Accordingly, the traditional markets are vulnerable to fire due to the initial unplanned structural problem so that the large scale fire damage occurs. The study is concerned with systematically classifying and analyzing the result by applying the TRIZ tool to the fire risk factors to extract the fundamental problem with the fire of the traditional market and make the active response. The study was done for preventing the fire on the basis of it and the expansion to the large fire in case of fire to prepare the specific measure to minimize the fire damage. On the basis of the fire expansion risk factor of the derived traditional market, the study presented the passive measures such as the improvement of the fire resisting capacity, the fire safety island, etc. and the active and institutional measures such as the obligation of the fire breaking news facilities, the application of the extra-high pressure pump system, the divided use of the electric line, etc.

The consumer perception on health and food habit, the experience of health food use and the discrimination between health food and drug of Korean consumer were surveyed by using a questionnaire containing 15 items in order to obtain the basic data for the assessment of the benefit and risk of health foods in Korea. A total of 1,000 people over 20 years of age living in Seoul and the vicinities were interviewed and asked to fill out the questionnaire during the period from the October 1995 to the February 1996. Among the 882 answers collected, 23 was incomplete data, and 859 answers were used for the statistical analysis by using SAS program. The perception of Korean consumer on health and food habit indicated that food habit was considered the most important factor for the maintenance of health, as appeared in 39.8% of the subjects, among which 93.9 % believed that food habit could cause disease, and 97.1% believed that disease could be cured by changing food habit. The most worried disease was cancer (30.6%), degenerative diseases (14.1%), diseases by accident (12.6%) and obesity (10.0%). The disease which likely to be caused by food habit was diabetes (35.6%), obesity (22.4%), high blood pressure (12.8%), constipation (12.7%) and cancer (7.9%). The disease which was believed to be cured by changing food habit was diabetes (40.1%), obesity (25.9%), constipation (16.5%), high blood pressure (7.4%) and cancer (3.3%). It appeared that the people had a perception that food habit was highly related with diabetes and obesity, but less with cancer which was mostly worried.

A survey was conducted to investigate the perceptions of health and foods, and the food habits among the elderly men who came to the Tap-Gol park on a daily basis. A total of 253 subjects were selected for this study. The data was analyzed through the $X^2-test$, Duncan's multiple range test and Pearson Correlation by the use of SAS program. The results were as follows. The majority of the subjects were in their 70's. 56.1% of them lived with their sons' families, 9.1% lived alone, and 27.3% lived with a spouse. 32% of the subjects were living with the expense less than 50,000 won per month. Although some were suffering from such diseases as arthritis, indigestion, and hypertension etc., the subjects were generally in good health. Their dependance on dietary supplements were insignificant. Most of the subject had a common-sensible notion as to health. They put emphasis on the three factors for the maintenance of good health: a balanced diet, a peace of mind and exercising. With regard to the food habits, the majority were fair in general. The subject living with family had more regular meals than the single people did. 41.5% of the subjects responded that they had irregular meals, mainly for lunch due to a poor appetite or a financial problem. The respondents cited protein food, milk, fruit, sea weeds and food cooked with oil as conducive to good health. But what they consumed did not match what they thought was good, particularly milk. The results of this study lead to the suggestion that Korea need to develop such a lunch program for the elderly as is practiced in the U.S., through which dietary motivation can be stimulated and a low-priced and balanced diet offered at least for one meal a day.

Despite the decrease in the number of children due to low birth rate, the domestic children's apparel market has been achieving steady growth as family income is rising thanks to more opportunities for working women, parents spend more on their children, and they prefer brand products that make their children look special. In addition, the market is suffering from hard competition as large enterprises have joined the race. The present study purposed to survey the children's apparel market in Korea, which is in a transitional period, and to contribute to the development of the market with Korean brands. For this purpose, we analyzed the characteristics of children's apparel brands in the 21st century based on the current state of the domestic children's apparel market and, based on the findings, forecasted the future trend of children's apparel brands, suggested improvements for expected problems, proposed standards for coping with changes such as diversification, high quality and differentiation in the children's apparel market, and provided consumers with information on how to purchase products. According to the result of analyzing the characteristics of children's apparel brands in the 21st century, brands are categorized largely into four types - life cultural brands, functional product brands, character brands and brands advancing to China. Life cultural brands equipped with all necessities for children are expanding, and with the deepening social problems of environmental pollution and the reduction of the child population, functional products made of environment-friendly materials are spreading widely, targeting infants and children. Furthermore, for extending age targets and diversifying products, children's apparel is using characters. The use of characters is expected to have a considerable effect on the growth of brands because children are more subjective as consumers than before and they are more easily persuaded with characters. Domestic children's apparel brands advancing to China have a high expectation of success in overcoming the limitation of the local market that has reached its peak and growing into global brands. Korean apparel makers are struggling to overcome the depressed domestic market, to recover consumers' consumption, to cope with market opening, to pursue high value of sensibility and to expand the seniors' market, etc. In this situation, future trends of children's apparel brands will be the expansion of family brands, brand totalization, quality price, niche market (pre-teen market), etc. In response to these trends, we made the following suggestions for improvement. 1. Children's apparel brands are evolving into family brands as well as into total brands through voluming. Today, however, apparel makers are advancing to the children's apparel market with the concept of adults' apparel and, as a result, children's apparel is merely adults' apparel of reduced size, having problems in design, color and materials. Thus, apparel makers must develop design considering the wide range of size and the characteristics of children's apparel, strengthen sourcing abilities to create revenues, and make thorough survey of customers to find common denominators between adults' apparel and children's apparel considering that characteristic that the target class is different from the buyer class. Furthermore, they must make active investments in human resources, develop outstanding products through advanced planning and design, and support marketing techniques and management systems to stores. 2. As the declining birth rate will continue to have a negative effect on the market, it may be difficult to expand the market size but there is still a margin for growth through high-sensibility and high-quality products. The competitiveness of brands is determined by their market shares. Accordingly, concepts should be specialized according to lifestyle, customers' diverse needs should be satisfied, and cross-coordination should be achieved within a brand. 3. Considering Korean parents who do not spare investment in their children despite shrinking consumption, functional products must be high value-added goods that can enhance efficiency. However, in the current situation of the infants' apparel industry where a textile manufacturer supply its products to multiple brands, it is difficult to develop unique products only based on materials. Thus, it is considered urgent to appeal to consumers not by relying on materials only but by finding methods of applying their own characters to children's dress.

For our survey of insecticidal resistance of Palm thrips (Thrips palmi Karny), we established the discriminating time (DT) and concentration (DC) of nine insecticides, and we conducted a bioassay about seven local populations via leaf-dipping methods. The discriminating times of the recommended concentration (RC) were 24 h at emamectin benzoate EC and spinetoram SC, 48 h at chlorfenapyr EC, 72 h at spinosad SC, cyantraniliprole EC, acetamiprid WP, dinotefuran WG, imidacloprid WP and thiacloprid SC after treatment. The DC estimated the concentration which showed the difference within the mortalities of these local populations. The DCs were emamectin benzoate EC $0.013mg\;L^{-1}$ (RC, $10.8mg\;L^{-1}$), spinetoram SC $0.125mg\;L^{-1}$ (RC, $25.0mg\;L^{-1}$), chlorfenapyr EC $0.25mg\;L^{-1}$ (RC, $50.0mg\;L^{-1}$), spinosad SC $0.083mg\;L^{-1}$ (RC, $50.0mg\;L^{-1}$) and cyantraniliprole EC $5.0mg\;L^{-1}$ (RC, $50.0mg\;L^{-1}$), and DCs of neonicotinoids were their RCs, that is, acetamiprid WP (RC, $40.0mg\;L^{-1}$), dinotefuran WG (RC, $20.0mg\;L^{-1}$), imidacloprid WP(RC, $50.0mg\;L^{-1}$) and thiacloprid SC (RC, $50.0mg\;L^{-1}$). From our investigation into the resistance of the local populations with DT and DC application, the neonicotinoid insecticides have shown a high resistant level for all the local populations, and the other insecticides have demonstrated low or non-resistance. In the use of neonicotinoid insecticides to control Palm thrips, one must take caution. As a result, the establishment of DT and DC in the single dose bioassay method was helpful for surveying the insecticide response dynamics and the development of an insecticide resistance management strategy.
