Background: Coffee extract has been investigated by many authors, and many minor components of coffee are known, such as polyphenols, diterpenes (kahweol and cafestol), melanoidins, and trigonelline, to have anti-inflammatory, anti-oxidant, anti-angiogenic, anticancer, chemoprotective, and hepatoprotective effects. Therefore, it is necessary to know its pharmacological effect on hepatocytes which show the most active cellular regeneration in body. Methods: In order to determine whether coffee extract has a beneficial effect on the liver, 20 C57BL/6J mice were intraperitoneally injected once with dialyzed coffee extract (DCE)-2.5 (equivalent to 2.5 cups of coffee a day in man), DCE-5, or DCE-10, or normal saline (control), and then followed by histological observation and IP-HPLC (immunoprecipitation high performance liquid chromatography) over 24 h. Results: Mice treated with DCE-2.5 or DCE-5 showed markedly hypertrophic hepatocytes with eosinophilic cytoplasms, while those treated with DCE-10 showed slightly hypertrophic hepatocytes, which were well aligned in hepatic cords with increased sinusoidal spaces. DCE induced the upregulations of cellular proliferation, growth factor/RAS signaling, cellular protection, p53-mediated apoptosis, angiogenesis, and antioxidant and protection-related proteins, and the downregulations of NFkB signaling proteins, inflammatory proteins, and oncogenic proteins in mouse livers. These protein expression changes induced by DCE were usually limited to the range ± 10%, suggesting murine hepatocytes were safely reactive to DCE within the threshold of physiological homeostasis. DCE-2.5 and DCE-5 induced relatively mild dose-dependent changes in protein expressions for cellular regeneration and de novo angiogenesis as compared with non-treated controls, whereas DCE-10 induced fluctuations in protein expressions. Conclusion: These observations suggested that DCE-2.5 and DCE-5 were safer and more beneficial to murine hepatocytes than DCE-10. It was also found that murine hepatocytes treated with DCE showed mild p53-mediated apoptosis, followed by cellular proliferation and growth devoid of fibrosis signaling (as determined by IP-HPLC), and subsequently progressed to rapid cellular regeneration and wound healing in the absence of any inflammatory reaction based on histologic observations.

This study was carried out to investigate the effect of lipid type on the physicochemical properties and sensory score of pork patties. The samples consisted of pork patties containing 20% pork fat (PP), 20% olive oil (OP), and 20% soybean oil (SP). The surface color, water holding capacity, increased rate in thickness, decreased rate in diameter, rheological properties, pH, VBN content and TBARS value were determined for the pork patties as the physicochemical properties: the sensory scores were also evaluated. The $L^*$ value for PP was the highest, and the lowest for OP among the samples (p<0.05). For the $a^*$ value OP was the highest among the samples, and the $b^*$ value of OP was lower than that of the PP (p<0.05). The water holding capacity and increased rate of thickness were higher for PP than for OP and SP (p<0.05). The cooking loss and decreased rate of diameter of PP were lower than those of OP and SP (p<0.05). The hardness and springiness of OP and SP were higher than those of PP, and SP had the highest chewiness among the samples (p<0.05). However, cohesiveness and gumminess were not different among the samples. The pH of SP was the highest among the samples, and the TBARS value of OP was lowest (p<0.05). The VBN contents were not different among the samples. The amounts of raw color for OP and SP were higher than that of PP (p<0.05). The raw aroma was not different among the samples. Also, roasted aroma and taste were not different among the samples, but the tenderness, juiciness, and palatability of SP were the highest among the samples (p<0.05).

The objectives of this study were to analyze nutrition-related problems and to develop the nutrition education programs for high school students A survey was conducted with 500 students in the second grade level at high schools in Daegu who differed in socio-economic characteristics. In addition, body composition analysis was accomplished by the Inbody 3.0. The developed questionnaires were distributed and 481 questionnaires were collected with a 96.2% of response rate. Statistical data analysis was completed using SPSS WIN(ver.12.0) for descriptive analysis, reliability analysis, factor analysis, t-tests and $X^2$-tests. We first analyzed students' problems related to nutrition and environmental factors. In a question addressing skipping breakfast, only 11.5% answered they "do not eat" breakfast. In regards to BMI, the male students' degree of obesity was higher. Second, we analyzed living environments, which greatly influence dietary behavior. For the snacks-related categories, most of the students liked bread, cake and other snacks. When they chose the snacks, they mainly considered taste. There were significant difference among the males and females(p<.01) in terms of snacks intake habits, where 43.1 % of the males answered they snack "occasionally" and 43.4% of the females answered they snack "according to how they feel". In the case of beverages, the males consumed significantly more(p<.001). Based on their regional groups, the area A group preferred milk and milk products, and the area B group preferred soft drinks. As for the time of beverage intake, 77.6% of the females answered "with snacks", which was significantly higher than 61.4% of the males(p<.001), 12.2% of the males drank beverages after exercise. For late snacking, 68.0% of the male students and 71.1 % of the female students consumed late snacks. Most of them preferred bread, cake and other snacks. The reasons for taking a late snack were "when I feel hungry" by 61.8% of the males which was higher than the females(p<.001), 23.6% of the females consumed late snacks "impulsively". Ideally, in order to improve the food habits of high school students effective and practical nutrition education programs that consider gender and regional school group, should be carried out.

The aim of this study was to investigate the effect of the addition of red wine on the physicochemical properties ana sensory score of cooked pork patties. The samples consisted of the pork patty without red wine(control), and 1, 3 and 5% red wine(RWP-1, 3 and 5, respectively). There were no significantly differences in the moisture$(58.1\sim58.7%)$, crude protein$(15.9\sim16.3%)$ crude fat$(23.2\sim23.7%)$, and crude ash$(2.7\sim2.9%)$ contents, and the Hunter's $a^*-value(0.2\sim0.6)$, cooking loss$(16.5\sim19.2%)$, VBN$(11.9\sim15.6mg%)$, total bacterial count($(11.9\sim15.6mg%)$ Log cfu/mL), hardness$(3,193\sim3,336\;dyne/cm^2)$, springiness$(75.8\sim79.7%)$, cohesiveness$(47.8\sim52.1%)$, gumminess$(489\sim509kg)$, chewiness$(183\sim209g)$ and strength $(1,144\sim1,199g)$ between the pork patties. Of the pork patties the $L^*$ value of the control and the b value of RWP-5 were the lowest(p<0.05). The pH and TBARS value of RWP-5 were the lowest of all the pork patties. The flavor of RWP-5 was superior to that of the other pork patties, and the taste, texture, juiciness and palatability of RWP-3 and RWP-5 were superior to those of the control and RWP-1. In conclusion, the addition of 5% red wine was most suitable for enhancing the physicochemical properties and sensory score of pork patties.

In the situation of rapid industrialization based on the lopsided development of economy since 1960, Korean rural society has faced a crisis of disruption. As a result, the civilian government has tried a few actions to change the circumstance. However, it is said that the coral polices were not satisfactory. Those who were concerned with the rural problems of these days argue that it is necessary to adopt new policies and further to change the policymakers` philosophies concerning the matter. The arguments are certainly based on the beliefs that the sound policies come from the sound philosophies. This study aims to analyze the existing rural polices and their policymakers` philosophies and to design of a new paradigm. For the purpose, this study was set there specific objectives: First, to overview the moor points of Quantitative Utilitarianism of Jeremy Bentham and the Social Justice Theory of John Rawls, the contrasting frameworks of the moral philosophies; Second, to trace the major or trade of the rural policies since 1960s in Korea; Third, to analyze the policymakers` philosophies reflected on the rural policies; Fourth, to design a new paradigm of the rural policies. This study mainly adopted descriptive method based on the various source of government and non-government statistics, white papers and other researches. The major findings of this study may be summarized as follows: 1. The historical epochs of the rural policies in Korea was divided into the periods: (1) An organizational and institutional establishment for self-reliance of main crops and the New Village Movement $(1969{\sim}70)$; (2) An initiation of `open-door` policies to the foreign farm products $(1970{\sim}80)$; (3) Completion of the UR meetings and the recommendations of the Rural and Fishery Development Commission (1980-present). 2. It was found that the philosophical foundations of coral policies were directly reflected from the utilitarianism of the national development. Under the philosophy it was the modem sector of economy that was to spearhead the national development, and the rural sector was situated to the peripheral position and hardly in the spot-light. Therefore, it may be said that the present situation of the rural society was largely rooted in the model of economic development. 3. As a new direction of the coral policies, many studies were focussing on the NTC (non-trade concerns) functions of agriculture for the present and future society. The researchers argue that the cost of protecting and supporting agriculture and rural society may be higher than that of the burden which the nation should be bear in the case of failure of agriculture. Although it tray be true, however, it should be noted that the argument is another type of utilitarianism which prevailed in the past. As a philosophy of rural policies, utilitarianism is straight forward and persuasive, however, it has also limitations in terms of relativism in broad sense or social justice in specific manna. 4. This study suggests to set the philosophical foundations of rural policies on the basis of Rawl`s Theory of Justice mentioned earlier. It emphasizes the inviolability of social justice which was neglected for the national benefits timing the period of development dictatorship in 1960s and 1970s. The principles of social justice for coral people were identified as twofold; (1) The principle of the t equal liberty; (2) (a) Difference principle, (b) The principle of fair equality of opportunity.

The purpose of this study was to examine the relationship between bone density and dietary intake for college women in their twenties. This study was performed on 160 female college students residing in Gangwon-do. It was conducted using ultrasound measurement of calcaneus bone density, anthropometric checkup and food-frequency questionnaires (FFQ) comprising 94 kinds of commonly consumed foods. Subjects were divided into two groups according to the T-score of bone density: a normal group (n = 113 persons, T-score ${\geq}1$) and a risk group (n = 47, T-score < 1.0). The average age of the subjects was 20.17 years and there was no significant difference between the two groups. Body weight and body fat percentage of the normal group were significantly higher than those of the risk group. The mean daily energy intake of the normal group was significantly higher than that of the risk group. Also, protein, fat, vitamin A, niacin, vitamin B6, folate, calcium, phosphorus, sodium, potassium, iron and zinc intake for the normal group were significantly higher than for the risk group. For the intake of the commonly consumed foods (or dishes) listed in FFQ, the mean daily intake amount of loaf bread, rice cake, potatoes, spicy beef soup, cucumber, seasoned spinach perilla leaves, crown daisy, stir-fried mushroom, sea mustard, beef rib, ham, chicken, mackerel, common squid, drink type curd yogurt, oriental melon and chocolate in the normal group was significantly higher than in the risk group. While, the mean daily intake of ramyun (instant noodle) and carbonated beverage by the normal group was significantly lower than that of the risk group. In conclusion, 20 something female college students showed a higher rate (26.9%) of the bone mineral density risk group (osteopenia or osteoporosis). For the risk group, the levels of nutrient and food intake were lower than in the normal group. Therefore, the bone density risk group needs to increase their nutrient intake and diet quality by increasing the intake of various foods. In addition, they should decrease the intake of foods, which are negative for skeletal health such as instant noodles and carbonated beverages.
