Purpose: The purposes of this study were to identify the segments of the Home Meal Replacement (HMR) market according to food-related lifestyle of Japanese consumers, and to investigate its demographic characteristics, the HMR purchase status and needs of new HMR product development. Methods: A total of 2,720 domestic consumers living in Japan were surveyed using a self-administered questionnaire and 488 responses were returned. Excluding responses with significant missing data, 467 responses were used for data analysis. Results: As a result of cluster analysis, three consumer segments were identified. The diet-highly concerned segment had the highest food-related lifestyle score, followed by the diet-moderately concerned segment, and the diet-unconcerned segment (p<0.001). A significant difference in demographic characteristics among the three segments was found with respect to the type of residence (p<0.05). There were significant differences in the main place (p<0.01) and average expense (p<0.001) for HMR purchases by food-related lifestyle segments. In the case of new HMR products that need further development, 'low-sodium products' had the highest demand scores in all three segments. In the diet-highly concerned segment, the mean scores of demand for new products were significantly higher than those in the other segments (p<0.001). Conclusion: The findings of this study can be used to develop new products for the Japanese' HMR market. The segments identified in this study should be updated and revised regularly to reflect changes in the characteristics of each food-related lifestyle segment.

The purpose of this study is to monitor the implementation of UN Convention on the Rights of the Children (CRC) and to find out new directions for the promotion on the children's rights in Korea. Based on the module of International Save the Children Alliance (1993) about the children's rights and the Indicators of Korean Children's Wellbeing (Korean Council for Children's Rights, 1999), the revised Korean child welfare law (2000) as a related domestic law has compared with the 54 articles of CRC (1989). The results of this study are analyzed as follows: The Korean child welfare law has only 2 articles on the civil and political rights of the children in special need and neglects the economic, social and cultural rights of the general children at home. In consequence the Korean law has few survival rights of the general children for securing their adequate living standards and supplementing their parents' role. And it limits only to the development rights of the children in special need, therefore, it neglects the genera: children's rights to information, play and leisure, cultural activities. Above all, it has only 2 articles on the participation rights of the children in special circumstances. On the other hand, based on the indicators of Korean Children's Wellbeing, the collected data say that the budget for the child welfare is only 1.12% of the total budget of the ministry of the health and welfare and its 96.28% is for the children in substitutional care. Based on the results, implications for practice and future research are discussed, and new directions for the promotion of the children's rights are also suggested.

Users of passenger ships and cruise ships are rapidly increasing year by year, and the needs of the floating architecture are newly come out. But the studies about the passengers' safety and the countermeasures against incidents on board the ships are rare, although the ships' incidents are occurred averagely 15 cases per year during last 10 years. For the purposes of the analysis of the safety consciousness and gathering the some of input data for evacuation simulation for Korean passengers on board ships, this study performed surveys targeting ordinary 394 passengers who are not specially trained and/or accustomed with onboard living conditions. The results are the followings. The reliability on ships' safety is surveyed as 32.3%. Only 14.6% of respondents are aware that there were safety education on board ship during sailing. And 42.2% and 40.9% of respondents answered that they saw the map of emergency routes and knew where the life boats are, respectively. And 73.3% select crews' direct or in-direct(like announcement by indoor broadcasting system) guidances as the most effective evacuation method.

The purpose of this study was to investigate the housewives's recognition and practice on prevention of environmental pollution. The subjects of this study were 250 housewives, school students' mothers, living in Cheong-ju. Major findings were as follows: 1. In washing their faces and brushing their teeth, they saved the water very well, but in taking bath, washing the dished, using the water of the lavatory they did not save the water so well. 2. The kinds of the cleansers differed in taking a bath, washing the hair, and doing the laundry respectively : what they use most was hard soaps in taking bath, liquid cleansers mixed with shampoo and linse in washing the hair, and synthetic powder detergent in laundrying. They used more synthetic detergent than natural soaps, which is known to be a cause of water pollution. Especially, when they cleansed, they did not use a measuring cup. It resulted in the waste of detergent and accelerating of water pollution. Therefore, the environmental education for them was very urgently needed. 3. In handling domestic waste, the separate collection rate of empty bottles and old newspapers was very high, but that of used phone-call cards and used batteries was extremely low. It was truly nessesary to educate and step up publicic activities on the separate collection of phone-call cards and batteries caused environmental pollution. 4. The housewives had much knowledge about environmental pollution, but they did not practice it so well in their home. 5. The housewives made more effort than their children in preventing environmental pollution and saving resources. In conclusion, what is most important for solving environmental problem was for each citizen to make an effort to prevent environmental pollution, and the government's support and producing the atmosphere of the society for this was really needed.

The international community recognizes North Korea's nuclear and missile provocation as a real threat. This is due to the analysis and evaluation that has developed nuclear electro magnetic pulse of domestic and overseas North Korea experts, intelligence agencies related to electro magnetic pulse. Electro magnetic pulse experts are concerned about North Korea's nuclear electro magnetic pulse in the following aspects. First, industrial, military, medical, and living facilities in modern society are constructed with electrical and electronic systems. So, All electrical and electronic appliances will become neutralization if North Korea's nuclear electro magnetic pulse was set off over the world(i.e. Korean Peninsula, United States etc). Second, North Korea will judge that possibility of criticism by the international community is low from the point of view of an attacker. Because nuclear electro magnetic pulse aim to destroy only the electronic equipment of the opposite nation and cause damage rather than taking life. Finally, nuclear electro magnetic pulse is more threatening than weapons like mass destruction because it does not need to hit targets accurately and can strike a wide area with nuclear weapon of the low technology levels. In this respect, we will analyze and evaluate nuclear and missile development and make a prospects about nuclear electro magnetic pulse developed by North Korea.

The beneficial effect of glycerol as a cryoprotectant, especially for sperm cryopreservation, has been shown in many studies. However, glycerol is toxic to living cells, and boar sperm in particular show greater sensitivity to glycerol than sperm from other domestic animals. Amides have been studied as alternative cryoprotectants for freezing stallion sperm. Sperm frozen in methylformamide or dimethylformamide as cryoprotectants show similar motility when thawed compared with sperm frozen in glycerol. We evaluated the cryoprotective effects of dimethylformamide on boar sperm freezing. To test the effect of amides, the concentration of boar semen was adjusted to $10^9sperm/mL$, and seminal plasma was removed using Hulsen solution. After centrifugation, the pellet was diluted in modified-Modena B extender. Lactose-egg yolk (LEY) extender was used as the cooling extender. The freezing extender was madeed aaddition of the optimal amount of glycerol and amides to LEY-Glycerol-Orvus ES Paste extender, and this extender was used for the second dilution. Diluted sperm were frozen in liquid nitrogen using the 0.5 mL straw method. Sperm frozen in extender with glycerol as a cderol were compared with those frozen in extender including the different amides. Sperm were tested for motility, viability, the sperm chromatin structure assay, and normal apical ridge after thawing. The percent of motile sperm diluted in glycerol was as high as that in the stallion study (61%). Dimethylformamide showed positive effects on sperm quality and was better than glycerol. Methylformamide provided similar sperm quality as glycerol. Therefore, dimethylformamide is useful for reducing cryoinjury in boar sperm and is expected to be useful as an alternative cryoprotectant.
