It is known that onions, or bioactive compounds therein, providehealth benefits. The present study was designed to investigate whether a concentrated onion extract lowered blood lipid levels in rats fed a high-fat diet. Initially, male Sprague-Dawley rats were housed singly in an environment in which temperature and light duration were controlled, and had free access to a nutritionally adequate AIN-93G diet and deionized water. After an acclimatization period, rats were weight-matched and assigned to one of the following five groups: 1) a control group, fed the AIN-93G diet mixed with 10% (w/v) lard and 0.7% (w/v) cholesterol to induce hyperlipidemia (control); 2) three experimental groups, fed the AIN-93G diet mixed with a high-fat source plus concentrated onion extract at three different levels (termed the low-dose, medium-dose, and high-dose groups); and, 3) a placebo group, fed the AIN-93G diet with fats plus the same concentrated extract but devoid of onion-derived material. All five groups freely ingested their respective diets over 6 weeks. At 0, 3, and 6 weeks, blood samples were collected from the orbital sinus following overnight food deprivation. At 6 weeks, livers were collected. Both control and experimental groups continually gained body weight throughout the study. No significant differencein body weight gain was observed among groups. However, the serum concentrations of triglycerides, total cholesterol, and non HDL-cholesterol were significantly reduced by ingestion of concentrated onion extract. Also, the hepatic levels of total lipids and total fatty acids, especially C18:1 (oleic acid), were significantly decreased in rats fed a high level of concentrated onion extract, compared with the control and placebo groups. These results provide clear evidence that ingestion of a concentrated onion extract has a profound inhibitory effect on serum lipid levels in rats fed a high-fat diet. Our findings indicate that a concentrated onion extract may be used to alleviate hyperlipidemia by lowering serum cholesterol and triglyceride levels.

Jeju Hallabong Tangor (Citrus kiyomi${\times}$ponkan) is a Citrus species with a variety of physiological properties such as anti-oxidant, anti-inflammation, anti-cancer, and anti-obesity. We investigated the anti-obesity effects of Hallabong Tangor peel extracts before (HLB) and after (HLB-C) bioconversion with cytolase based on modulation of adipocyte differentiation and lipid metabolism in 3T3-L1 adipocytes. Treatment with cytolase decreased flavanone rutinoside forms (narirutin and hesperidin) and increased flavanone aglycone forms (naringenin and hesperetin). During adipocyte differentiation, 3T3-L1 cells were treated with 0.5 mg/mL of Sinetrol (a positive control), HLB or HLB-C. Adipocyte differentiation was inhibited in both citrus groups, but not in control and Sinetriol groups. HLB and HLB-C tended to reduce insulin-induced mRNA levels of CCAAT/enhancer-binding protein ${\alpha}$ ($C/EBP{\alpha}$) and sterol regulatory element-binding protein 1c (SREBP1c). Compared to the control and Sinetrol groups, HLB and HLB-C markedly suppressed insulin-induced protein expression of $C/EBP{\alpha}$ and peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$). The HLB and Sinetrol groups, but not HLB-C group, significantly increased adipolytic activity with higher release of free glycerol compared to the control group in differentiated 3T3-L1 adipocytes. These results suggest that bio-conversion of Hallabong Tangor peel extracts with cytolase increases aglycone flavonoids. Irrespective of bioconversion, both Hallabong Tangor peel extracts exert anti-obesity effects that may contribute to prevention of obesity through inhibition of adipocyte differentiation or induction of adipolytic activity.

For the newly approach of policy with the old aged era at hand, the result which examines the 1,200 students attending professional colleges and upward in three small-to-medium sized cities, for two months, from October 1, 1996 to November 30, in order to know the change of consciousness of the growing modern young intellectual age group is as follows. 1. The objects of survey consist of 72.1% of women, 40.4% of 20 to 21 age, 49.1% of atheists, and people from big cities and fishing and agrarian village occupy equally 40.2%. Concerning the long-termed residents, 49% of them dwell in big cities. In case of the parents' age is more than 55, 31.5% in fathers, and 10.9% in mothers. 2. The types of housing in which they desire to reside in their getting older are : 72.8% of them hope to live in individual houses, 16.6% in apartments or villas, and 3.4% in social welfare facilities. Out of respondents, compared with other groups, man rather than woman, those who are 20 to 21 age group and from fishing and agrarian villages and have over 7 family members and live with their parents have a higher preference for independent houses. 3. The districts in which they hope to live when they are old are : 41.6% of them, with the highest percent, hope to live in farming villages, the older they are, the more they hope to live in agricultural district, and women of 21 years and upward hope to live in big cities. On the other hand, the preferable degree for social welfare facilities is higher each in people who are 24 years and upward, buddhists, self-boarding students, and the more poorly they are off, the higher the percent is. 4. The types of preferable welfare facilities for the elderly are : 58.2% of them think silver towns desirable, 28.4% think the charged (or free) elderly welfare facilities. Compared with other groups, the percentage which prefer silver towns is higher in women, people from big cities, residents of main family, long-termed city residents, people with higher income, people having grandparents alive, and people who had experience of taking lectures on hygienics or social welfare. 5. 50.3% of the respondents insist that provision of living expenses against old age should be insured by social security system, and 42.8% by the elderly themselves. The percentage of the former shows higher in people of 21 years and upward, women, residents of fishing and agrarian villages, christians, people in more needy circumstances and people who have experience of using a medical institution. 6. Compared with other nations, 54.5% of the respondents have an opinion that elderly welfare and welfare work in Korea stays in insufficient level and most of them are women, people from farming village, residents of head family, people having younger parents and people being worse health condition, and they have a more positive attitude about the elderly welfare work. 7. 92.3% of the respondents answered that a national budget for the elderly welfare is scarce, and the percentage is higher in people who are older, residents of big cities, people in lower living condition and people in worse health condition. 8. 35.2% of the respondents answered that the proper cost of their old age must be over 220mi11ion. The more a family's total income is, the higher the percentage is. 9. The factors which have an effect on the preference of silver towns are sex(p<0.01, the type of the present residence(p<0.05), and a family's total income(p<0.05). 10. From the survey result of the above, we comes to the conclusion that, for the sake of welfare of the increasing elderly population, government authorities and parties concerned must exert their utmost for the elderly welfare by increasing a budget of it and establishing a number of facilities of the elderly welfare and silver towns located in fresh and comfortable villages. In addition, they have to set up a course of hygienics in all the colleges and instruct the contexts on hygienic welfare as well.

This study considers the characteristics of the separation of public and private security service during Koryo dynasty, and compares it with the modern security service. Modern day security service's definition of private and public security service was used to distinguish them. Given the different historical settings, it's difficult to argue that the distinction between public and private service during Koryo dynasty was clear, but it can be said that public security service was centered around palace guard and concerns the activities of protest, and military made for the relationship, and private security service was centered around power of DoBang and includes the activities of malingering, and Byolchogun. During the early days of Koryo, protest, district military and soldiers who stay in the palace were all parts of a palace revolt and this institutional improvement of soldiers who stay in the palace was accomplished during King Seongjong's rule. The tradition of a palace revolt can find its roots in the middle military, and after the unification, a palace revolt was reformed into the king's palace revolt of second and the 6th along the course of establishing the nation's system. All of the changes stem from the reformation for consolidating the royal authority. Gyung Dae Seoung wanted to protect himself and he slept with his army night and days and because of that, group of soldiers was created and it was called DOBANG. Some members were from dobang gyeonryong, The forced were powerful because it was gathered with a warriors with extraordinaire martial arts and competent management. Most of the soldiers followed gyeong dae seung because they believed that he has a strong leadership and loves his people, and had a strong faith in him. However, the general gyeong jang had a belief that politics must be reverted to the previous so the relationships between jungbang wasn't smooth. Because of the economic operational problems, due to fraud committed by the mens under his command failed to maintain integrity and was criticised.The misconception also fed up with the emperor and the deepening relationships between the soldiers, his dobang was dismantled. After he took over the dobang, for his personal safety and to strengthen his position he compensated gyeon dae seong's dobang and developed the organization. In the process of extending the dobang Choi chung heon recruited many talented people to strengthen the military base, and also accepted the advice and expanded the power of Dobang. Choi Chung Heon thus consolidated his political gains by weakening the power of the king's army and adjusting the myth, which could've threatened his regime, and this was called Dobang number 6th. Dobang number six got even more powerful by his son named Choi woo, and after ruling, he expanded into a room, and a substantial reorganization of Dobang was developed. And then the creation of yabyeolcho also showed the effect to prevent the crisis. Although the palace guards who were public security service of Koryo Dynasty was still maintained during the military rule era when the royal authority was incapacitated, it was only maintained to have a symbolic meaning as the actual authority including military power was with Choi, the master of Dobang, private security service group. Likewise, during the rule of Choi, private securty service could reign over public security service, and the noteworthy characteristic of Dobang is that it assisted the private soldier groups to seize the military power by reorganizing and modifying military system. Although both differences and similarities can be found when comparing the guards of Koryo Dynasty with those of contemporary society, they have a similarity in terms of the essence of guards that they guarantee the safety of their clients. As for differences, the royalty of Koryo Dynasty and the pursuit of profit of contemporary society are in contrast, and contemporary guards can be seen as the fulfillment of responsibility and duty by free will, whereas guards of Koryo Dynasty were ruled with military coercion.

Locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate despite the advances in modern radiation therapy techniques. Combination of chemotherapy and radiation therapy demonstrated benefit in improving local control and possibly the overall survival. Twelve patients with advanced stages (Figo stage III, IV) or 11b with bulky tumors (>5 cm in diameter) were treated with combination of radiation therapy and concurrent weekly cisplatin between May of 1988 and September of 1991 at Inje University Paik Hospital. Cisplatin was administered in bolus injections of 50 mg at weekly intervals during the courses of radiation therapy. Median follow-up period was 34 months with ranges from 3 to 53 months. Eleven patients were evaluable for the estimation of response. Response was noted in all the 11 patients: complete response (CR) in 7 ($64\%$), partial response (PR) in 4 ($36\%$). Of the 7 patients with CR, all maintained local control, whereas only 1 of 4 with PR showed local control. Six of 7 with CR are alive disease free on the completion of follow-up. Eight of 11 patients ($73\%$) maintained local control in the pelvis. The median survival for CR patient is 27 months and 9 months for the PR patients. Analysis of survival by stage shows 11 b 4/5, III 2/3 and IV 1/3. Overall survival rate was $61\%$. Three patients recurred: 1 at local, 1 in distant site and 1 with local and distant site. Toxicity for the combination therapy was not excessive. These results are preliminary, but definitely encouraging in view of markedly improved response rate compared with the results of historical control group.

The purpose of this study was to provide the basic resources for developing a parish nursing program. We did this by investigating what demands were made on the parish nursing service by the parishes or churches under review. The subjects of this study were 96 pastors located throughout the City of Busan. NP (New paragraph) $\gg$ We conducted our research by utilizing a modified version of the study created by Hwang (2000) and by using the help of prior research and professionals gathered from the parish nurse questionnaire by Djupe (1990). The data in this study were collected from July 1 to Oct. 31, 2001, using the questionnaire method. The Data were analyzed by: (a) frequency: (b) percentage: (c) mean: (d) standard deviation, and x^2-test$ with SPSS/PC program. The study has found the follows: 1. For subjects making demands on the parish nursing service, 95.8% were in need of using the services of parish nurses. On the demands of parish nursing service for the subjects, 95.8% the necessity of parish nursing services. And they answered by their intention of asking for parish nursing service practice. 2. Of the subjects under review, 71.9% were part-time workers and 28.1% were full-time employees 71.9% of part time and 28.1% of full times duty. In terms of the method of pay for work, 41.8% were pay free or freelance while 51.2% were on salary. And engagement intention of parish nurse as preacher was 88.5%. 3. The demand for nursing services in various categories were as follows. (a) hospice care: (4.02 1.11), (b) health screening: (3.98 1.09), (c) home visiting: (3.97 1.16), (d) group health education: (3.81 1.12), (e) organization of volunteer groups: (3.75 1.12), (f) individual health education: (3.75 1.14), (g) advice on choosing hospital or hospital consultation: (3.69 1.21) and (h) individual counseling: (3.51 1.31). 4. In terms of the specific services rendered by parish nurses. our study found that services were needed for the following: physical symptom management; preparation before death in spiritual preparation for death, blood pressure check in health examination, home visiting where the patient makes phone call, management of chronic disease in group health education, disease management in individual health education, advice on choosing hospital, or hospital consultation: and physical problems in individual counseling. 5. With respect to whether there was a correlation between what church a pastor came from and the types of demands made, there was NO significant difference found. 6. In relation to the characteristics of the subjects and their church and the hope demands (duty pattern and method of payment and engagement intention of parish nurse as preacher) for parish nurses, these had non significant differences. In conclusion, the perception of parish nursing service is very high. Moreover, we found that there is a great demand for well ordered parish nursing services to promote the health of each congregation. Before doing so, it would be better to make things known and to consider the relevant characteristics shown in the researched results.

Purpose : The authors aimed to analyze the long-term effects of treatments, especially external beam radiotherapy (EBRT), in bilateral retinoblastoma patients. Methods : This retrospective study analyzed the medical records of 22 bilateral retinoblastoma patients who were registered between October, 1987 and October, 1998 and followed-up for more than 10 years. They were treated by enucleation, EBRT, and systemic chemotherapy. Age at diagnosis, sex, delay prior to treatment, Reese-Ellsworth (RE) classification, and the local treatment modalities were analyzed in relation to recurrence-free survival (RFS) and complications. Results : Median age at diagnosis was 7.0 months (range 1.7-31.6 months). Leukocoria was the most common presenting feature. Two patients had a familial history. The RE classifications of the 44 eyes were group II in 4, III in 14, IV in 4, and V in 22. At the end of a median follow-up period of 141 months (range 55-218 months), 20 patients were alive. The 10-year ocular survival rate of the 44 eyes was $56.8{\pm}7.5%$. The 10-year RFS and ocular survival rate of the 29 eyes treated by combined EBRT and chemotherapy were 75.9% and 86.2%, respectively. Treatment delay (>3 months) was found to be related to higher risk of recurrence. Complications after EBRT were cataract, retinal detachment, phthisis bulbi, and facial asymmetry. No patient developed a second malignancy during the follow-up period. Conclusion : Early detection and prompt treatment can increase ocular survival rates. In addition, careful attention should be paid to possible long-term sequelae in these patients.

Quantitative analysis of MR spectrum depending on mole concentration of the contrast media in cereberal metabolite phantom was performed. PRESS pulse sequence was used to obtain MR spectrum at 3.0T MRI system (Archieva, Philips Healthcare, Best, Netherland), and the phantom contains brain metabolites such as N-Acetyl Asparatate (NAA), Choline (Cho), Creatine (Cr) and Lactate (Lac). In this study, optimization of MRS PRESS pulse sequency depending on the concentration of contrast media (0, 0.1 and $0.3mmol/{\ell}$) was evaluated for various repetition time(TR; 1500, 1700 and 2000 ms). In control (cotrast-media-free) group, NAA and Cho signals were the highest at TR 2000 ms than at 1700 and 1500 ms. Cr had the highest peak signal at TR 1500 ms. When concentration of contrast media was $0.1mmol/{\ell}$, the metabolites were increased NAA 73%, Cho 249%, Cr 37% at TR 1700 ms compared with other TR, and also signal increased at $0.3mmol/{\ell}$, In $0.5mmol/{\ell}$ of contrast agent, cerebral metabolite peaks reduced, especially when TR 1500 ms and 2000 ms they decreased below those of control group. The ratio of metabolite peaks such as NAA/Cr and Cho/Cr decreased as the concentration of the contrast agent increased from 0.1 to $0.5mmol/{\ell}$. Authors found that the optimization of PRESS sequence for 0.3T MRS was as follows: low density of contrast agent ($0.1mmol/{\ell}$ and $0.3mmol/{\ell}$) made the highest signal intensity, while high density of contrast agent reveals the least reduction of signal intensity at 1700 ms. In conclusion, authors believe that it is helpful to reduce TR for acquiring maximum signal intensity.

The present study was conducted to investigate the effects of concentrate feeding on rumen papillae development in suckling Hanwoo calves before weaning (60 days of age). Twenty-four Hanwoo calves (12 heifers and 12 bulls) at six days of age were randomly assigned to one of three dietary treatments [hay and two levels (low and high) of concentrate feeding] and given each diet with free access to their dams for suckling until 60 days of age. At 60 days of age, two calves from each treatment were sacrificed and used for post-mortem examination of rumen papillae development. Feed intake between 31 and 60 days of age was significantly higher (P<0.05) for the high concentrate treatment (380.2 g/d) than for other treatments (58.3 and 76.9 g/d for hay and low concentrate treatments, respectively). Although feed intake showed a large difference between the low and high concentrate treatments, body weights at birth and 60 days of age were similar between the two treatments, suggesting that calves in the low concentrate feeding suckled more milk from their dams than those in the high concentrate feeding. The ratio of reticulo-rumen weight to body weight at 60 days of age was significantly increased (P<0.05) in the high concentrate (1.39%), compared with those in the hay (0.85%) and low concentrate (1.06%) treatments. Furthermore, the high concentrate feeding significantly increased both rumen papillae length and width, compared with the hay and low concentrate feeding group. This was also detected clearly by visual observation. The blood concentration of ${\beta}$-hydroxybutyrate was significantly higher for the high concentrate (176.4 ${\mu}mol/L$) than for other treatments (58.9 and 59.2 ${\mu}mol/L$ for the hay and the low concentrate group, respectively). In conclusion, the results of the present study showed that, to achieve a large development of rumen papillae before weaning (60 days of age) in suckling Hanwoo calves, the amount of concentrate intake should be important. And also the results implied that hay might not be included in the diet for suckling Hanwoo calves before weaning (60 days of age).

This study was carried out to investigate the physiochemical and microbiological changes of dandelion during fermentation. Thirty and fifty percentage raw sugar groups (SFE30 and SFE50) were introduced into dandelions and fermented for 120 days at $15-20^{\circ}C$. This study was conducted to investigate the utilization of sucrose on lactic acid bacteria from dandelions and their effect on the pH, titratable acidity, microorganism and formation of organic acids in dandelions during fermentation. The number of lactic acid bacteria increased remarkably up to 15 days of fermentation and then decreased rapidly thereafter. The maximum number of lactic acid bacteria, 7.9 log CFU/mL was reached at pH 4.17 and the pH of dandelion showed a slight decrease during fermentation and decreased steadily up to 90 days to reach an optimum pH of 4.0. The titratable acidity of dandelions fermented increased during fermentation. The concentration of organic acid, amino acid and free sugar in SFE30 was higher than both SFE50 and DWE. The results of dandelions fermented were remarkably retarded in the 50% raw sugar group compared to the 30% raw sugar group.
