Elementary schools students'degree of satisfaction on school food service and food preference were surveyed from 352 sixth-grade students in Kwangju and Chonnam area from June 22 to July 3 to enhance the quality of foodservice. The degree of satisfaction was high with cooked rice and soup in terms of temperature and serving state. There were significant differences in the degree of satisfaction depending upon the types of foodservice (p<0.001). There was significant differences in degree of satisfaction for side dishes depending upon the temperature (p<0.05), kinds (p<0.01) and amount (p<0.001). The degree of satisfaction with Kimchi was generally high in the serving state (p<0.05) and the amounts (p<0.01). The degree of satisfaction with desserts were high in the amount (p<0.001). The amount of leftover was high with soup, side dishes, kimchi, cooked rice, and desserts in order. The improvements made on children's behavior after the implementation of the school foodsevice were the adaptation to balanced diet and spending less money on sweets. The factors of influencing the school foodservice and the children's food intake were the education in school (teachers and dietitians) and the health status of their bodies (p<0.001). Children's favorite foods were sweet and sour pork, pork cutlets, oranges, watermelons, and strawberries in order. The least preferred foods were garlic seasoned with soy sauce, raw vegetables of broad bell-flowers, crown daisy greens, and steamed peppers. Children's favorite food types were fried food, desserts, one course meal, and bread. The least preferred types were pickled food, green and seasoned vegetables, cooked rice, and hard-boiled food in order. Generally, the children in the rural area favored most foods compared with those from urban area.

This study was conducted to develop methods of promoting traditional Korean Kimchi globally. To accomplish this, 99 Spanish natives were surveyed for their sensory evaluation and awareness of Kimchi. The results revealed that a relatively high number (46.9%) of the respondents had eaten Korean Kimchi. After eating the Kimchi, women tended to provide a slightly higher overall acceptability than men. Furthermore, when the overall sensory evaluation was conducted, the characteristics of Kimchi that were most recognized were its red color, spicy smell and hot taste. In addition, 93.9% of the respondents said that Korean Kimchi was a suitable food based on its spicy flavor>chewing force>appearance>red color>fermented smell. However, 6.1 percent of the subjects responded that they did not find Kimchi appetizing due to its hot taste>fermented smell>chewing force. Interestingly, the hot taste was a common selection for the reason that individuals liked or disliked Kimchi. When ranked among traditional Spanish foods, Kimchi was reportedly similar to cooked cabbage, cooked bell peppers, cooked red peppers and Moheu ppikan, pickles, Spanish lettuce, chiseutora and oil pickled cheese, or to various vegetables pickled in vinegar. Taken together, the results of this study should facilitate the globalization of Kimchi. In addition, the findings of this study provide fundamental data that should assist in the development of a local style of Kimchi for Spain.

The continually growing demand for underground space in dense urban cities is also driving the demand for underground highways. Building the underground highway tunnel, however, can involve complex design and construction considerations, particularly when there exists divergence or convergence in the tunnel. In this study, interaction between two asymmetric noncircular tunnels-that is, a larger main tunnel and a smaller tunnel diverging from the main tunnel, was investigated by examining the distributions of the principal stresses and the strength/stress ratio for varying geometric conditions between the two tunnels depending on diverging conditions using both numerical analysis and scale model test. The results of numerical analysis indicated that for the $0^{\circ}$, $30^{\circ}$, $60^{\circ}$ diverging directions, the major principal stress showed an initial gradual decrease and then a little steeper increase with the increased distance from the left main tunnel, except for $90^{\circ}$ where a continuous drop occurred, whereas the minor principal stress exhibited an opposite trend with the major principal stresses. The strength/stress ratio showed generally a bell-shaped but little skewed to left distribution over the distance increased from the left larger tunnel, similarly to the variation of the minor principal stress. For the inter-tunnel distance less than 0.5D, the lowest strength/stress ratio values were shown to be below 1.0 for all diverging directions ($0^{\circ}$, $30^{\circ}$, $60^{\circ}$ and $90^{\circ}$). The failure patterns observed from the model test were found to be reasonably consistent with the results of numerical analysis.

Background: Goshajinkigan (GJG) is used for the treatment of several neurological symptoms. We investigated the efficacy of GJG and mecobalamin (B12) against neurotoxicity associated with docetaxel (DOC) in breast cancer patients. Materials and Methods: Sixty breast cancer patients were treated with DOC. Thirty-three patients (GJG group) received oral administration of 7.5 g/day GJG and 27 patients (B12 group) received oral administration of 1500 ${\mu}g/day$ B12. Neuropathy was evaluated according to DEB-NTC (Neurotoxicity Criteria of Debiopharm), Common Terminology Criteria for Adverse Events (NCI-CTC) ver. 3.0, and a visual analogue scale (VAS). This study employed a randomized open design. Results: The incidence of neuropathy was 39.3% in the GJG group, and 88.9% in the B12 group (p<0.01). In the GJG group, grade 1 DEB-NTC was observed in 2 cases, grade 2 in 5 cases and grade 3 in 5 cases. Grade 1 NCI-CTC was observed in 7 cases, grade 2 in 6 cases, and VAS was $2.7{\pm}2.2$. In the B12 group, grades 1, 2 and 3 DEB-NTC were observed in one case, 12 cases and 12 cases, respectively; and grades 1, 2 and 3 NCI-CTC were observed in 11 cases, 12 cases and one case, and VAS was $4.9{\pm}2.4$. Conclusions: Concomitant administration of GJG is useful in preventing neuropathy in breast cancer patients treated with a DOC regimen.

The present study was designed to observe whether nutritional education on children or mothers of the children who avoid to eat vegetables can improve the preferences for the vegetables of the subjects. The subjects were 45 children who are fourth to sixth grade of primary school in Bibong. They were assigned to one of three groups which are Control, Children Education and Mothers Education groups. Control group was not given any special education, while experimental groups were given nutritional education for 4 weeks. The effects of education was evaluated in the aspects of preference changes for vegetables, nutritional knowledge, attitude and food behavior of the subjects The results are summarized as follows. 1. Preferences to cucumber, lettuce, chinese cabbage and raddish were high in three groups while greenonion, onion, lotus roots and red pepper didn't suit for their taste. 2. Significantly increased scores for the preference to red pepper, pumpkin, Dorajee(root of chinese bell-flower), braken, mushroom was shown only in the children who had nutritional education while the children in the group of Mothers Education improved their preference only cabbage and lotus roots. 3. Nutritional knowledge of the children in Children Education group has improved significantly(p<0.05). While there was no significant difference between control and Mothers Education group. 4. When scores for food habit of mother and children were estimated, there was no significant difference among three groups. However, score of food habit in children was higher than that of mothers. 5. Food habit and nutrition knowledge of mother were not well corelated with dietary attitude and behavior of their children. These results indicate that the program of nutrition education in the present study can improve the food choice of children for vegetable and correct one-sided food habit. The program applied in this study would serve a kind of model for the dietetic teachers to guide the children who mainly dislikes vegetables.

The full-genome sequences of fourteen isolates of Broad bean wilt virus 2 (BBWV2), collected from broad bean, pea, spinach, bell pepper and paprika plants in Korea during the years 2006-2012, were determined and analyzed comparatively along with fifteen previously reported BBWV2 genome sequences. Sequence analyses showed that RNA-1 and RNA-2 sequences of BBWV2 Korean isolates consisted of 5950-5956 and 3568-3604 nucleotides, respectively. Full-length genome sequence-based phylogenetic analyses revealed that the BBWV2 Korean isolates could be divided into three major groups comprising GS-I (isolates BB2 and RP7) along with isolate IP, GS-II (isolates BB5, P2, P3 and RP3) along with isolate B935, and GS-III including 16 BBWV2 Korean isolates. Interestingly, GS-III appears to be newly emerged and predominant in Korea. Recombination analyses identified two recombination events in the analyzed BBWV2 population: one in the RNA-1 of isolate K and another one in the RNA-2 of isolate XJ14-3. However, no recombination events were detected in the other 21 Korean isolates. On the other hand, out of 29 BBWV2 isolates, 16 isolates were found to be re-assortants, of which each RNA segment (i.e. RNA1 and RNA2) was originated from different parental isolates. Our findings suggested that reassortment rather than recombination is a major evolutionary force in the genetic diversification of BBWV population in Korea.

The broadband and discrete sources of sound in small cooling fans of propeller type and centrifugal type were investigated to understand the turbulent vortex structures from many bladed fans using ANSI test plenum for small air-moving devices (AMDs). The noise measurement method uses the plenum as a test apparatus to determine the acoustic source spectral density function at each operating conditions similar to real engineering applications based on acoustic similarity laws. The characteristics of fans including the head rise vs. volumetric flow rate performance were measured using a performance test facility. The sound power spectrum is decomposed into two non-dimensional functions: an acoustic source spectral distribution function F(St,.phi.) and an acoustic system response function G(He,.phi.) where St, He, and .phi. are the Strouhal number, the Helmholtz number, and the volumetric flow rate coefficient, respectively. The autospectra of radiated noise measurements for the fan operating at several volumetric flow rates,.phi., are analyzed using acoustical similarity. The rotating stall in the small propeller fan with a bell-mouth guided is mainly due to a leading edge separation. It creates a blockage in the passage and the reduction in the flow rate. The sound power levels with respect to the rotational speeds were measured to reveal the mechanisms of stall and/or surge for different loading conditions and geometries, for example, fans installed with a impinging plate. Lee and Meecham (1993) studied the effect of the large-scale motions like impinging normally on a flat plate using Large-Eddy Simulation(LES) and Lighthill's analogy.[ASME Winter Annual Meeting 1993, 93-WA/NCA-22]. The dipole and quadrupole sources in the fans tested are shown closely related to the vortex structures involved using cross-correlations of the hot-wire and microphone signals.

Depression is a psychiatric syndrom consisting of dejected mood, psychomotor retardation, insomnia and weight loss, sometimes associated with irrational guilt feeling. And it is also similiar to Hwa-byung(火病) symptom in oriental medicine. But it is difficult to diagnose with objective method. Digital Infrared Thermographic Imaging(D.I.T.I.) is one of diagnotic method that measure the changes of skin temperature in body. Specially we checked the skin temperature on depressed patients by using D.I.T.I. and compared with Bell's palsy patients and normal persons group. The results are as follows; Average body temperature of the depressed patient group is $36.68{\pm}0.43^{\circ}C.$ and that of the control group is $36.73{\pm}0.40^{\circ}C.$. So there is no meaningful difference. The depressed patient group has higher temperature than the control group by ${\triangle}T>1.0^{\circ}C$ at the following acupuncture points in these body parts - upper and lower, left and right, anterior and posterior. When acupuncture points temperature was compared superior and inferior part of the body, depressed patient group have meaningful difference at the GV-4(Myung-moon) and also in the control group. When acupuncture points temperature was compared left and right part of the body, depressed patient group have no meaningful difference and also in the control group. When acupuncture points temperature was compared in the anterior and posterior part of the body, depressed patient group have meaningful difference at the GV-4(Myung- moon) and also in the control group. From this study, we think that D.I.T.I. could be used to diagnose objectively on the depressed patients and useful to another psychoneurogenic diagnosis in oriental medicine.
