To determine the contents of sodium (Na) and potassium (K) for restaurant dishes, 194 cases classified 26 kinds of restaurant dishes were collected from restaurants in Seoul and were analysed using the atomic absorption spectroscopy. Average contents of Na and K in Kimchi among restaurant dishes were highest as $554.9{\pm}155.5mg/100g$, $225.1{\pm}69.1mg/100g$, while average contents of Na and K were lowest in Seolleongtang as $24.2{\pm}5.8mg/100g$, $12.7{\pm}3.9mg/100g$ respectively. The contents between Na and K in restaurant dishes had a strong correlation of positive linear judging from 0.782 (p-value < 0.01) of the correlation coefficient. The Na/K ratio of Bulgogi was appropriate as $1.17{\pm}0.44$, while those of Udon, banquet noodles, Kalguksu were very high as shown more than 10. The contents of Na and K were examined 5 dish groups as Gook/Tang, Jjigae/Jeongol, stir-fried dish, noodle and Kimchi. Average contents of Na and K classified by dish groups were significantly difference (p-value < 0.001). Average content of Na among dish groups was highest in Kimchi as $554.9{\pm}155.5mg/100g$ followed by Jjigae/Jeongol, Gook/Tang, stir-fried dish and noodle. Similar to Na content, average content of K was highest in Kimchi as $225.1{\pm}69.1mg/100g$ followed by stir-fried dish, Jjigae/Jeongol, Gook/Tang and noodle. The ratio of Na/K by classified groups of dishes was shown as significantly difference (p-value < 0.001). Stir-fried dish was $1.18{\pm}0.44$ close to 1 followed by Kimchi, Jjigae/Jeongol, Gook/Tang, and noodle.

Purpose: The purpose of this study is to provide baseline data for the development of an educational program for hospice care for college students. Methods: A survey was conducted at three universities in B city with 143 students from September 5, 2014 through September 26, 2014. The data were analyzed by the SPSS 18 program. This study was approved by IRB. Results: The college students' spiritual well-being was at a medium level. Their attitudes to death were neutral, and perception of hospice care was at a medium level. Most of the participants (93.0%) had no training in hospice care. The participants' awareness of the purpose of hospice care was at a relatively high level. Their awareness of the need for hospice care was at a moderate level. The participants' spiritual well-being and their attitudes to death showed a weak but positive correlation (r=0.179, P=0.030). The relationship between their spiritual well-being and awareness of hospice care were positively correlated (r=0.203, P=0.015). Conclusion: The participants' perception of hospice care was low. Most of them had no experience of hospice care education. Also, the higher the spiritual stability was, the higher the participants' perception of the purpose and the necessity of hospice care was. And their perception of the hospice care varied depending on their family relationship, satisfaction with school life, and cognition of hospice care. Therefore, we need consider these variables to develop a hospice education program to enhance college students' attitudes to death and their perception of hospice care.

The purpose of this study is to evaluate the relationship between high sensitive C-reactive protein (hsCRP) and pulse transit time (PPT). Apparently healthy 233 subjects had been enrolled in the health promotion center of the Pusan National University Hospital from Jan. 29 to Feb. 26, 2004. They had no previous history of diabetes, hypertension and hyperlipidemia. Subjects were categorized according to tertiles of hsCRP level [Group 1: first tertile $(0.01\;{\sim}\;0.02\;mg/dl)$, Group 2: second tertile $(0.03\;{\sim}\;0.05\;mg/dl)$, Group 3: third tertile $(0.06\;{\sim}\;0.12\;mg/dl)$, and Group 4: Fourth tertile $(0.13\;{\sim}\;16.8\;mg/dl)$]. PTT body mass index (BMI), total cholesterol (T-C), LDL-cholesterol(LDL-C), blood sugar (BS), systolic blood pressure (sBP) and diastolic blood pressure (dBP) were significantly different among hsCRP groups (p<0.05). HsCRP is positively related with BMI, tryglyceride (TG), LDL, sBP and dBP (p<0.05), and negatively related with PTT and HDL-cholesterol (HDL-C) (p<0.05). PTT is significantly negatively related with hsCRP, T-C, TG, LDL-C, BS, dBP and sBP (p<0.05). The hsCRP and PTT were related before controlling BMI, T-C, LDL-C, sBP, and dBP, but not related after conkolling. The relationship between hsCRP and PTT depends on cardiovascular disease risk factors.

Three species of Fusarium, F. fujikuroi, F. verticillioides and F. proliferatum, are known to be associated with bakanae disease of rice [1, 2]. F. fujikuroi infects rice flowers and survive in endosperm and embryo of the seeds. Infected seed is an important source of primary inoculum of pathogens [3]. Seeds of rice (Oryza sativa cv. Boramchan) collected from bakanae-infected field were found to be 96% infected with Fusarium sp., 52% with F. fujikuroi, 42% with F. verticillioides, and 12% with F. proliferatum as determined by incubation method and species-specific PCR assays. F. fujikuroi was detected at lemma/palea, endosperm and embryo whereas F. verticillioides and F. proliferatum were recovered only from lemma/palea by means of component plating test. Seed disinfection methods have been developed to control bakanae disease and prochloraz has been most widely used for rice seeds. Two chemicals formulated with prochloraz (PC 1) and prochloraz + hexaconazole (PC 2) that inhibit biosynthesis of ergosterol strongly reduced the incidence of Fusarium spp. on selective media to 4.7% and 2.0%, respectively. Disease symptoms of rice seedlings in nursery soil were alleviated by chemical treatment; seedlings with elongated leaves or wide angle between leaf and stem were strikingly reduced from 15.6 to 3.2% (PC 1) and 0 (PC 2), stem rots were reduced from 56.9 to 26.2% (PC 1) and 32.1% (PC 2), and normal seedling increased from 0.4 to 13.3% (PC 2). Prochloraz has some disadvantages and risks such as the occurrence of tolerant pathogens [4] and effects on the sterol synthesis in animals and humans [5]. For these reasons, it is necessary to develop new disinfection method that do not induce fungal tolerance and are safe to humans and animals. Chlorine dioxide ($ClO_2$), that is less toxic, produces no harmful byproducts, and has high oxidizing power, has been reported to be effective at disinfection of several phytopathogenic fungi including Colletotrichum spp. and Alternaria spp. [6]. Gaseous $ClO_2$ applied to rice seeds at a concentration of 20 ppm strongly suppressed mycelial growth of Fusarium fujikuroi, F. verticillioides and F. proliferatum. The incidence of Fusarium spp. in dry seed with 8.7% seed moisture content (SMC) tended to decrease as the concentration of $ClO_2$ increased from 20 to 40 ppm. Applying 40 ppm $ClO_2$ at 90% relative humidity, incidence was reduced to 5.3% and resulted in significant reduction of disease symptoms on MS media. In nursery soil, stem rot was reduced from 56.9 to 15.4% and the number of normal seedlings increased from 0.4 to 25.5%. With water-soaked seeds (33.1% SMC) holding moisture in the endosperm and embryo, the effectiveness of disinfection using $ClO_2$ increased, even when treated with only 20 ppm for four hours. This suggests that moisture was a key element for action of $ClO_2$. Removal of the palea and lemma from seeds significantly decreased the incidence of Fusarium spp. to 3.0%. Seed germination appeared to decrease slightly by water-soaking at $30^{\circ}C$ because of increased SMC and by physical damage of embryos from hulling. These results indicate that the use of gaseous $ClO_2$ was effective as a means to disinfect rice seeds infected with Fusarium spp. and that moisture around the pathogens in the seed was an important factor for the action of $ClO_2$. Further investigations should be conducted to ascertain the best conditions for complete disinfection of Fusarium spp. that infect deep site of rice seeds.

Underlying malocclusions and dentofacial deformities are often related to variations in the craniofacial development. Type I and type II collagens are considered the major collagens of bone and cartilage respectively. Monitoring the patterns of those protein expressions during development will Provide a basis for the understanding of normal and abnormal growths. This study was undertaken to investigate the morphogenetic changes and the expression patterns of type I and II collagen proteins involved in the developing mandible of human embryos and fetuses. 50 embryos and fetuses were studied with Hematoxylin and Eosin, Alcian, blue-PAS, Masson Trichrome, md Immunohistochemical stains. The results were as follows : 1. A 13.5 mm embryo showed the stomatodeum with dental lamina, maxillary and mandibular processes. Meckel's cartilage appeared in the mandibular arch of a 20.5 mm embryo. New bone formation was bilaterally initiated at the outer side of middle portion of Meckel's cartilage of 22-38 mm embryos. 2. Meckel'cartilage was resorbed at the 15th week fetus. The endochondral ossification was observed where there was direct replacement of cartilage by bone. Meckel'cartilage disappeared and membraneous ossification were observed at the 25th week. 3. Before the appearance of Meckel's cartilage, the expression of type I collagen was moderate at the odontogenic epithelium of maxillary & mandibular process, but mild for the expression of type II collagen. 4. During the appearance of Meckel's cartilage and new bone formation, the immunoactivity of type II collagen was more expressed than type I collagen at the Meckel's cartilage and new bone. 5. During intrarmembranous bone formation, the expression of type II collagen was rare in the bony trabeculae. There was a switch for the expression of collagens from type II to type I during the appearance of Meckel's cartilage.

This study was intended to investigate food, exercise habits, perception of health status and the effects of nutrient intake of female college students. Food habits such as regularity of meal time, repast of breakfast, numbers of night snack per week and duration of meal were assessed via a self reporting questionnaire, and 24hrs recall method for nutrient intake was obtained from 155 female college students in Yangju-si. The mean height and weight of the subjects were $161.25{\pm}3.52cm$ and $52.26{\pm}4.52kg$, respectively. The average intakes of energy and nutrients were below the Korea recommended dietary allowance(RDA). Especially, The nutrient intakes(energy, protein, fat, fiber, calcium, iron, phosphorus, zinc, sodium, potassium, vitamin B6, niacin, vitamin C, folate, vitamin E, cholesterol) of the group in which the regularity of meal time per week was 5~7 days was significantly higher than the group in which the regularity of meal time was < 3 days (p<0.005). The nutrient intakes influenced by the food habit such as the regularity of meal time, skipping breakfast, and the numbers of night snack per week but did not differ in accordance with the regular exercise habits and perception of health status. These findings suggest that nutritional education based on female college students' food habits(regularity of meal time, skipping breakfast and night snacks per week, and duration of meal) may be required to improve dietary variety. It is considered that the improvement in dietary habits will contribute to the improvement of nutrition.

Background: Chronic eosinophilic pneumonia(CEP) presents with profound systemic symptoms, including fever, malaise, night sweats, weight loss, and anorexia together with localized pulmonary manifestations such as cough, wheeze, and sputum. It is an illness occurring predominantly in women. The chest radiogragh shows fluffy opacities that often have a characteristic peripheral configuration. The hallmark of CEP is the peripheral blood eosinophilia and a prompt response to oral corticosteroid therapy. We investigated characteristics of eleven patients of chronic eosinophilic pneumonia, reported in Korea. Method: There were eleven reports of CEP from 1980 to 1996, including three cases experienced in our hospital. The journals were analysed in respects of clinical history, laboratory, and radiographic findings. Results: 1) Male vs. female ratio is 3 : 8. The peak incidence occurred in forty and fifty decades. The atopic diseases were present in 6 cases. Asthma was the commonest manifestation 2) The presenting symptoms were as follows: cough, dyspnea, sputum, weight loss, fever, general weakness, night sweats, urticaria with the descending incidence. 3) Peripheral blood eosinophilia was present in all patients(mean ; 38.4%) and serum IgE level was elevated in nine patients(mean ; 880IU/ml). Conclusion: The diagnosis of chronic eosinophilic pneumonia is based on classic symptoms, including fever, night sweats, weight loss with a typical roentgenogram of peripheral pulmonary infiltrates and peripheral blood eosinophilia, and that is confimed by lung biopsy and/or bronchoalveolar lavage. Chronic eosinophilic pneumonia is responsive to corticosteroid promptly and recommended at least 6 months of therapy to prevent relapse.

Momordica charantia L. is a valuable food and medicinal plant of the gourd family (Cucurbitaceae) that is cultivated in tropical and subtropical regions of the world. Physicochemical properties of M. charantia based on cultivars, parts and growing stage were investigated. Crude protein contents of leaf were 27.5%, 26.9%, and 23.6% in native leaf (NL), cv. Erabu leaf (EL), and cv. Dragon leaf (DL), respectively. In particular, the crude protein content was the highest in leaves. The crude fat content was in the order of developmental stage 1 of cv. Erabu fruit (EF1) and developmental stage 1 of native fruit (NF1) with values of 4.0%, and 3.9%, respectively. There was also high amount of crude fiber in stem of all three cultivars. The crude ash content was in the order of cv. Erabu leaf, cv. Dragon leaf, and developmental stage 3 of native fruit (NF3) with values of 23.2%, 17.4%, and 13.6%, respectively. The major minerals found in M. charantia were K, Ca, and Mg. The potassium contents of developmental stage 3 of native fruit (NF3), developmental stage 3 of cv. Dragon fruit (DF3), cv. Dragon stem (DS), and developmental stage 2 of native fruit (NF2) were 498.37, 339.21, 314.30, and 307.34 ㎎ /100g, respectively, while the calcium contents were decreased of EL, DL, and NL with values of 513.45, 371.69, and 209.43 ㎎/100g, respectively. The calcium content was higher in leaves and stems than fruits. On the otherhand, the highest magnesium content was measured in EL (69.92 ㎎/100g). The highest contents of chlorophyll a, chlorophyll b, and total chlorophyll were found in NL (442.9 ㎎/100g dw), EL (759.6 ㎎/100g dw), and EL (1164.9 ㎎/100g dw), respectively. The vitamin C contents from developmental stage 2 of cv. Erabu fruit (EF2), NF3, developmental stage 3 of cv. Erabu on fruit (EF3), and NF2 were found with values of 2849.9, 2330.5, 1985.1, and 1844.5 ㎎/㎏, respectively, and found to be higher in Korean cultivar and Erabu fruit than in Dragon. The charantin contents of leaf were higher than the fruit found to be 547.71, 506.04 and 395.62 ㎍/g dw in DL, EL and EF2, respectively. According to the results, mineral contents, total chlorophyll and charantin contents of M. charantia were higher in the leaves (EL and DL) than the fruits. And, vitamin C content was the highest in the fruit (EF2 and EF3). Therefore, much more research needs to be undertaken to use of the leaves as well as fruits. The data showed that M. charantia can be considered a good source of nutrient for application in food system.

The purposes of this study were to determine the estimated dietary fiber (DF) intakes per capita/day of Korean as of 2001 by age groups and sex, and to analyze the major food sources of DF using the data on per capita consumption of each food reported in the 2001 Reports of Korean National Nutrition Survey and the newly-established DF database. The mean daily intakes of DF of Korean increased with increasing age until 49 years and thereafter decreased with aging. The intakes of DF/1,000 kcal increased with increasing age until 64 years and thereafter decreased with aging. On the average, the Korean people under age of 49 did not meet adequate intake (AI) of DF (12 g/1,000 kcal) in Dietary Reference Intakes (DRI) for the Koreans. The male people less satisfied the AI than the female did. The major food groups contributed to DF intakes of Korean adults were high in the order of vegetables, cereals, fruits, seasonings, legumes and seaweeds. Regardless of age and sex, vegetables, cereals and fruits were three major sources of DF for Koreans who obtained approximately 75% of DF from those sources. It has been shown that rice was the first single food source of DF intake for the age groups less than 12 years, however Kimchi was the first major source for all the age groups over 12 years. The infant and elderly groups obtained more DF from 10 major single food sources than the other age groups did. The results of the study revealed that the present levels of DF intakes of Korean in all age groups except the elderly group are insufficient to meet the AI for DF. Therefore the beneficial effects of DF on health and the increased consumption of DF from the variety of food sources should be emphasized through the continuous nutritional education.

Purpose : To evaluate the dose on a contralateral breast and the usefulness of shielding according to the distance between the contralateral breast and the side of the beam by breast size when patients who got breast implant receive radiation therapy. Materials and Methods : We equipped 200 cc, 300 cc, 400 cc, and 500 cc breast model on the human phantom (Rando-phantom), acquired CT images (philips 16channel, Netherlands) and established the radiation treatment plan, 180 cGy per day on the left breast (EclipseTM ver10.0.42, Varian Medical Systems, USA) by size. We set up each points, A, B, C, and D on the right(contralateral) breast model for measurement by size and by the distance from the beam and attached MOSFET at each points. The 6 MV, 10 MV and 15 MV X-ray were irradiated to the left(target) breast model and we measured exposure dose of contralateral breast model using MOSFET. Also, at the same condition, we acquired the dose value after shielding using only Pb 2 mm and bolus 3 mm under the Pb 2 mm together. Results : As the breast model is bigger from 200 cc to 500 cc, The surface of the contralateral breast is closer to the beam. As a result, from 200 cc to 500 cc, on 180 cGy basis, the measurement value of the scattered ray inclined by 3.22 ~ 4.17% at A point, 4.06 ~ 6.22% at B point, 0.4~0.5% at C point, and was under 0.4% at D point. As the X-ray energy is higher, from 6 MV to 15 MV, on 180 cGy basis, the measurement value of the scattered ray inclined by 4.06~5% at A point, 2.85~4.94% at B point, 0.74~1.65% at C point, and was under 0.4% at D point. As using Pb 2 mm for shield, scattered ray declined by average 9.74% at A and B point, 2.8% at C point, and is under 1% at D point. As using Pb 2 mm and bolus together for shield, scattered ray declined by average 9.76% at A and B point, 2.2% at C point, and is under 1% at D point. Conclusion : Commonly, in case of patients who got breast implant, there is a distance difference by breast size between the contralateral breast and the side of beam. As the distance is closer to the beam, the scattered ray inclined. At the same size of the breast, as the X-ray energy is higher, the exposure dose by scattered ray tends to incline. As a result, as low as possible energy wihtin the plan dose is good for reducing the exposure dose.
