A survey was conducted to determine the relationship between BMI and the dining out behaviors of 316 university students in Seoul area for May and September, 2006. The subjects included 114 males and 202 females. General characteristics and BMI determined that of the students 56 (17.7%) were underweight, 222 (70.3%)were normal, 23 (7.3%) were overweight, and 15 (4.7%) were obese. There were differences in BMI according to age, sex, and major. Students majoring in natural science and engineering were 58.3% and 51% normal weight, respectively, and the next most common weight class was overweight. The non smoking group showed had primarily normal weight subjects followed by underweight-subjects, but the smoking group had primarily normal weight subjects followed by overweight subjects (P<0.001). The frequency of dining out for breakfast significantly correlated with BMI (P<0.05). The group that frequently dined out for breakfast were primarily of normal weight followed by overweight subjects, but the group that rarely dined out for breakfast were primarily of normal weight followed by underweight subjects(21.4%). Groups whose criteria for selecting dining out meals were flavor and price showed a higher percentage of underweight subjects than other groups. The group whose motivations for choosing dining out meals were convenience and habit showed a higher percentage underweight subjects than other motivations. The group that selected the Western food menu for dining out showed a higher percentage of underweight subjects than other food menu groups. And, the groups that selected Japanese and Korean food were primarily of normal weight followed by underweight subjects, but the result was not significant.

Because the Energy Efficiency Design Index(EEDI) came into effect in 2013, it is necessary to develop a new technology to overcome $CO_2$ emission regulations. In structural design viewpoint, lots of researches are carried out to develop eco-friendly and high fuel efficiency ships by weight reduction. By using the automated compartment arrangement system and automated structural design algorithm which were developed by the authors, new researches are performing to combine the above two systems. However, the effect of weight reduction was not significant because structural designs by using these systems for the midship part was carried out only focused on the minimum still water bending moment. In this paper, at first, good compartment arrangements which give the minimum still water bending moment and(or) shear force were chosen by using the automated compartment system. And then, influence of shear force on weight reduction was investigated by using the automated structural design algorithm considering longitudinal strength, local strength and shear strength of longitudinal members in cargo holds. Conclusively, it is necessary to consider the minimum still water bending moment and shear force simultaneously to reduce the weight of mid-sized bulk carrier. Also, good compartment arrangement which gives much more weight reduction compared with existing ship was proposed.

This experiment was performed to study the morphological changes of the goblet cells in the rabbit duodenal mucosa after common bile duct ligation. Healthy adult rabbits weighting about 2kg body weight were divided to normal and bile duct ligated groups. Common bile duct ligation was performed under ether anesthesia. Experimental animals were sacrificed on the 1st, 3rd, 5th, 7th and 14th day after the operation. Mucosal specimens from the upper part of duodenum were fixed in 2.5% glutaraldehyde-1.5% paraformaldehyde, followed by 1% osmium tetroxide, embedded in araldite mixture, cut with LKB-V ultratome, stained with uranyl acetate - lead citrate, and observed with JEM 100 CX II electron microscope. Observed results were as follow : 1. In the early stages(1st-5th day) of the experiments, the goblet cells showed apocrine and merocrine secretion. But those of the late stage(7th and 14th day) groups showed exocytotic merocrine secretion. 2. In the late stage of the experiments, there found than increase of newly formed goblet cells that contain electron lucent cytoplasms. 3. In the goblet cells of normal rabbit, mucous granules with higher or lower electron densities are found together in the cytoplasm, and electron lucent mucous granules occasionally fused together. But in the early stage of the common bile duct ligation, goblet cells contained granules of higher electron densities. 4. Considering the above findings, common bile duct ligation probably initiates the hypersecretion of mucous granules of goblet cells in the early stage, and may facilitate the differentiation of goblet cells in the later stage.

Purpose: The objective of this study was to examine the clinical results and effectiveness of resection arthroplasty for correction of lesser toe deformity. Materials and Methods: From January 2000 to November 2012, 92 cases of resection arthroplasty for lesser toe deformity were reviewed. Hammer toe was the most common type of deformity, accounting for 44 toes (33 patients). Hallux valgus was the most common comorbid illness. Second toe was the most commonly affected toe and proximal interphalangeal joint was the most common location of resection arthroplasty (69 toes, 75.0%). We also analyzed the alignment of phalanges using the last follow-up weight bearing radiographic image. The analysis included clinical evaluation with American Orthopaedic Foot and Ankle Society (AOFAS) score as well as subjective satisfaction. Results: Flexor tenotomy (19 cases) was the most common combined surgery. Floating toe (4 cases) was the most common complication. The last follow-up alignment of phalanges was better than good in 71 toes (77.2%) in anteroposterior view and in 69 toes (75.0%) in lateral view. Sixty one cases (85.9%) resulted in better satisfaction than 'good' and the final average AOFAS score was 87.4. Conclusion: Resection arthroplasty is a valuable surgical option for treatment of lesser toe deformity, with high patient satisfaction, easy surgical technique and remarkable correction of deformity.

The common octopus, which has a high growth rate and high market price, is a prime candidate for commercial marine aquaculture operations. We evaluated the effectiveness of two types of shelters (pipe and tire types) for juvenile common octopus growing out in flow-through seawater tanks. Growth rates were evaluated in two experiments. The first experiment (Experiment 1) ran for 72 days, and the second (Experiment 2; replicated) ran for 46 days. Each trial included 40 octopuses fed a diet of frozen sardine (Sardinops melanostictus) and swimming crab (Portunustri tuberculatus) at 3-8% of body weight once every 3 days. In the two experiments, the respective specific growth rates were 0.3 and 0.04%/day in pipe-type shelters and 0.00 and 0.88%/day in tire-type shelters, while the respective percentage survivals were 80 and 80% in pipe-type shelters and 70 and 90% in tire-type shelters. Shelter type had little influence on the growth rate (P < 0.05).

This is a retrospective study on 452 patients with maxillofacial bone fracture. The patients were treated at the Dept. of Oral and Maxillofacial Surgery, WON KWANG UNIV. HOSPITAL from Aug. 1, 1984 to Sept. 30, 1988. The results were as follows. 1. The facial bone fractures occured most frequently in the twenties (35.3%)and male were predominant(75%) than female. 2. The most frequent etiologic factor was traffic accident. 3. The most common location of facial bone fracture was mandible(57%). Zygomatic bone & arch(39.9%) were most common on middle 1/3 of the face and symphysis(37.1%) were most common on the mandible. 4. The time from injury to treatment was variable from under the 1 week (65%) to over the 1 week(35%). In most case of the patients were treated beyond the 3 days(51.5%). 5. The relationship of intermaxillary fixation period and treatment method was an intimate relationship. The IMF period was reduced by the use of plate and screw osteosynthesis. 6. The weight loss was proportioned to intermaxillary fixation period.

This study was conducted to evaluate the possible utilization and the replacing range of fish meal analogue (FMA) as a dietary animal protein source for fish meal replacer in fingerling common carp, Cyprinus carpio. Leather meal, meat and bone meal, feather meal, squid liver powder, poultry by product meal, blood meal and amino acids were selected as ingredients for FMA. fish averaging 12.5 g were fed one of five isonitrogenous and isocaloric diets containing fish meal and/or FMA as the dietary animal protein sources. Fish meal protein (0, 20, 40, 60 or 100%) was replaced by the graded level of FMA protein. The feeding trial was conducted for 12 weeks after one week of conditioning period. Percent weight gain of fish fed diets containing 20%, 40% and 60% FMA were not significantly different from that of the fish fed the control diet (P>0.05). Feed conversion ratio of fish fed diets containing 20%, 40%, 60% and 100% FMA were not significantly different from that of fish fed control diet. These findings suggest that replacement of fish meal protein by FMA could be possible up to 60% of fish meal protein in fingerling Israeli carp diets.

A common kestrel (Falco tinnunculus) was presented with inability to stand and fly at Chungnam Wild Animal Rescue Center. The kestrel showed non-weight bearing ambulation on both legs and crepitation with no external wound. Radiographs revealed a fracture on mid-diaphysis of right tibiotarsus and a distal end fracture of left femur. Intramedullary pinning was chosen for reduction of both fractures. The right tibiotarsal fracture was corrected first, and left femur was repaired 5 days later. The kestrel was managed with a specially designed sling to prevent further iatrogenic damage for 2 weeks. Three weeks after the surgery, the kestrel was able to stand and found to perch in 4 weeks. On 5 weeks, The kestrel could fly free at outdoor aviary and was released through rehabilitation for 3 months finally.
