  • CATCH 22 syndrome is a one of the most common chromosome microdeletion syndrome with multiple organ anomalies in humans, with an incidence of approximately 1:4,000 to 1:5,000 live births. It is caused by a microdeletion of 1.5 to 3.0 megabases on the long arm of chromosome 22. The phenotypic spectrum of this disorder is wide and various. A 19-year-old patient who showed delayed growth and development (Height; 110 cm, Weight; 18 kg) was referred to our department for the treatment of dental cavities. She was diagnosed as CATCH 22 syndrome in 2004. Physical examination revealed hypertelorism, a short philtrum, thick reflected lips and a small mouth. She underwent cleft palate surgery at 1 year of age and heart valve surgery due to the cardiovascular abnormality at 13 years of age. Convulsive seizures had persisted until 5 years ago but are well controlled at present. Oral examination showed poor oral hygiene, crowding, prolonged retention on #65, 75 and dental cavities on #16, 21, 65, 26, 36, and 46. Cavity treatment and prophylaxis were performed under general anesthesia. Also continuous follow-up checks have been carrying out with the periodic prophylaxis and dental home education. Problems with numerous cavities and gingivitis which can lead to specific risks are common for CATCH 22 syndrome patients. It is therefore of great importance that these patients are referred to foremost physician and dental specialist for the oral care. In addition, preventive treatment targeting the risk of dental cavities and gingivitis is especially important and, as the syndrome involves many different medical problems, the dental treatment should be carried out in collaboration with the patient's physician.

  • The chestnut management standard diagnostic table is developed and would be utilized in order that a manager raising chestnuts checks where the own level of management is and grasps current state of own for the purpose of planning aims and advancing toward a higher level. The developed 'Chestnut management standard diagnostic table' consisted of 3 first classified items, 19 second classified items and 2 product indicator items by the chestnut experts consultative meeting. A survey of 212 farmhouses in 4 major producing area was conducted. Except invalid survey of 53 farmers, 159 farmhouses interviewed were used in analysis. Total score was calculated with sum of each item's score. According to the survey results, average score is 68.0 and Buyeo received the highest score of 69.7 and Suncheon received the lowest score of 61.8 by regional groups. The higher the group in score, the better it is in output per hectare. But the property of 'the ratio of the best products in total products' does not show a statistical correlation. Generally the score of 'management-based evaluation indicator part' and 'management and sale capacity indicator part' in Suncheon was low because of many elderly people. In part of 'manufacturing technology indicator' as Environmentally-Friendly production is progressed in over 70% of four regions, when comes to a disease and insect pest control there are rarely farmhouses having a way of crop dusting.

  • Although the South Korean organic food market is in the infancy compared to other industrialized countries, Korean consumers'interest in organic food and retail stores devoting space to organic products have been rapidly increasing. Despite the fact of organic food popularity, the term "organic" is interpreted differently by individuals. As opposed to the US, Japan and the EU where have operated an integrated organic food labelling system, Korea has adopted complex organic labelling systems regulated by several different government bodies. As a result, complicated food labelling standards make consumers confused when purchasing organic foods. Furthermore, in terms of country of origin (COO), it is argued by a lot of researchers that COO effects vary from product to product and from country to country; moreover, other informational cues such as brand and price can influence COO effects. In modern society, COO labelling has been complicated, due to the sourcing, manufacturing and market locations of merchandise spread over the world. Accordingly, the evaluation of COO effects has become complex. In order to examine these issues, a quantitative research was selected to classify the commonfeatures of organic food consumers and construct statistics such as the extent to which people are aware of organic food and COO labellingvia a questionnaire which took place in two cities in Korea with a cluster sample of 161 organic food purchasers. As for the data analysis, one-way analysis of variance (ANOVA), T-tests, bivariate crosstatulations with Cramer's V were conducted,depending on the characteristics of variables and the assumptions the research data need to fit. It has been concluded that in general, Korean organic consumers comprehend the term "organic"in a closer way to the general concept rather than technical term, thus people do not appreciate environmentally labels which include organic food labels, although marital status influence the degree of label awareness, regardless of gender, age, education level and so on. Regarding COO effects on organic food, home organic products were Korean consumers'first choice over those from industrialized countries and developing nations. Specifically, in processed organic product category, domestically cultivated and processed organic products were absolutely preferred to leading national brands produced with imported ingredients and international brands. However, due to a lack of checks of ingredients' COO, consumers tend to purchase a leading national organic food brand, believing that it is a pure organic food sourced domestically. As a consequence, this research has suggested some important managerial implications and future research directions. In order to prevent consumer confusion when buying organic foods, it should be noted that consumers do not comprehend the organic food certifications, due to complicated labelling systems for organic produce and processed organic foods. Therefore, government bodies related to organic food distribution have to know consumers' perception of organic food labels and the significance of customer-oriented labels and reestablish labelling standards. Similarly, public advertising should be followed to raise public awareness of the labelling to enable customers to have the correct information. In addition, not only international marketers but also domestic marketers need to understand COO images and also the influence COO of ingredients has on the image of an organic product.

  • Since the high readable source codes help us to understand and modify the program, it is much easy to maintain them. The readability of source code is not only affected by the complexity of algorithms such as control structures but also affected by the coding styles such as naming and indentation. Although various coding standards have been presented for promoting the readability of source codes, it has been usually lost or ignored in a programming course. One of the reasons is that the coding standard is not a hard-and-false rule since it does not contribute to the performance of software. In this paper, we propose a simple automatic system, namely StyleJigsaw, which checks the style of the source codes written by C/C++ or Java. In this system, the coding style score is calculated and visualized as a jigsaw puzzle. To measure the educational effectiveness of StyleJigsaw, several experiments have been conducted on a class students in C++ programming course. According to the experimental results, the coding style score increased about 8.0 points(10.9%) on average using StyleJigsaw. Further, according to a questionnaire survey targeting the students who attended the programming course, about 88.5% of the students responded that StyleJigsaw was of help to learn the coding standards. We expect that the StyleJigsaw can be effectively used to encourage the students to obey the coding standards, resulting in high readable programs.

  • Fast and reliable message broadcasting is critical for safety critical applications of VANET due to the urgency and/or significance of the messages for passengers and drivers. For reliable message delivery, a mechanism for checking the reception of message at the neighboring vehicles and retransmitting it if necessary is required. Especially, in urban environments, where the traffic density tends to be high, mechanisms that minimize control message overhead such as beacon are appropriate in order to minimize the message collisions. Furthermore, broadcast delivery is especially difficult at the intersection due to the road side obstacles such buildings, and hence, a mechanism that enables effective and efficient delivery across intersections is required. In this paper, we propose a beaconless reliable and efficient broadcast approach which specifically taking into account the urban streets. The proposed approach checks the message reception of neighboring vehicles implicitly by taking into account the broadcast of message by next vehicle as the acknowledgement. When retransmissions is necessary around the intersections, vehicles located within the intersection area, where the chance of successful signal propagation toward every branch of the intersection is higher due to less signal attenuation caused by road side obstacles, are to do the retransmissions. Simulation results show that the proposed approach can provide better reliability while consume less resources than the existing approaches.

  • This study was conducted to determine which factors would predict metabolic syndrome (MetS) perception and exercise by applying a machine learning classifier, or Extreme Gradient Boosting algorithm (XGBoost) from July 2014 to December 2015. Data were obtained from the Korean Community Health Survey (KCHS), representing different community-dwelling Korean adults 19 years and older, from 2009 to 2013. The dataset includes 370,430 adults. Outcomes were categorized as follows based on the perception of MetS and physical activity (PA): Stage 1 (no perception, no PA), Stage 2 (perception, no PA), and Stage 3 (perception, PA). Features common to all questionnaires for the last 5 years were selected for modeling. Overall, there were 161 features, categorical except for age and the visual analogue scale (EQ-VAS). We used the Extreme Boosting algorithm in R programming for a model to predict factors and achieved prediction accuracy in 0.735 submissions. The top 10 predictive factors in Stage 3 were: age, education level, attempt to control weight, EQ mobility, nutrition label checks, private health insurance, EQ-5D usual activities, anti-smoking advertising, EQ-VAS, education in health centers for diabetes, and dental care. In conclusion, the results showed that XGBoost can be used to identify factors influencing disease prevention and management using healthcare bigdata.

  • This study investigated the status and problems of the post-project environmental management for development projects and suggested improvements of the system to achieve effectiveness for the system of the sea area utilization consultation. The post-project environmental management has had several problems such as the neglect of implementations and checks for the consultation items, the lack of actions and notifications of results, the absence of awareness and expertise of the post-project environmental management. In addition, although it is very important to verify results of actual change and modelling of marine environment before and after the projects, the marine environmental monitoring and assessment have been perfunctorily carried out. Thus, for the improvements of the post-project environmental management to the system of the sea area utilization consultation, it is extremely necessary for related stakeholders to raise awareness of the post management and implement it faithfully, and establish the post management system for conflict resolution and enforce sanctions and accountability against executory items. Furthermore, it should establish systematic monitoring system of marine environmental impact survey.

  • This study was conducted to investigate the effects of feeding various Lactobacillus on performance, nutrients digestibility, intestinal microflora, and fecal noxious gas of broiler chicks. One thousand eighty one dat old male broiler chicks were fed into Lactobacillus crispatus avibrd 1(LCB), Lactobacillus reuteri avibro 2(LRB), Lactobacillus crispatus avihen 1(LCH), and Lactobacillus vaginalis avehen 2(LVH) at the level of $10^{4}$ and 10(sup)7cfu/g diet. There were four replicates with thirty chicks per pen. Diets contained ME 3,100, 3,100kcal/kg, and CP 22.0, 20.0% for starting and finishing period, respectively. Weight gain of checks fed Lactobacillus spp. tended to increase from the first week and was higher from 50 to 100g in Lactobacillus treatments than control. Feed intake and feed conversion were not statistically different of all treatments. Dry Matter(DM) digestibility of Lactobacillus treatments was tended to improve compared to that of control, but was not significantly different. Protein and Ca digestibility were also tended to improve in Lactobacillus treatments relative that of control. Lactobacillus treatments showed improved tendency in crude ash and fat compared to those of control, whereas phosphorus digestibility was not consistency. Nutrients digestibilities of bird fed LCH were superior to those of other treatments. It showed significantly higher in Ca and P digestibility than control(P〈0.05). Total Lactobacillus spp. of birds fed various lactobacillus was significantly higher in ileum for five weeks(P〈0.05), but was not different at cecum. Yeast was thought to be not completely attached to intestinal lumen for one week. However, total number of yeast was significantly increased in cecum and ileum from three weeks old chicks(P〈0.05). The number of anaerobes exhibited to tendency the increase in Lantobacillus treatments from one week old of age at both ileum and cecum. Moisture contents of birds fed Lactobacillus spp. was shown from 27 to 30% at five weeks old, whereas it was 38.2% in control. It decreased approximately 25% in Lactobacillus treatments relative to that of control and showed significance between them(P〈0.05). Fecal $NH_{3}$ gas emission was significantly decreased in Lactobacillus treatments and maintained $\frac{1}{3}$to $\frac{1}{2}$ of control(P〈0.05). LCH and LVH treatments were most effective to decrease fecal $NH_{3}$ gas and especiallt impreved ti significantly at the level of the level of 10(sup)7cfu/g diets covpared to that of $10^{4}$ cfu/g diets and control(P〈0.05). In conclusion, feeding Lactobacillus spp. increase performance and nutrients digestibilities of broiler chicks and improve environments of house. Proper supplemental level of Lactobacillus spp. is considered more than $10^{4}$ cfu/g diet.
