Objectives: This study was conducted to investigate the relationship between watching mukbang (eating broadcasts) and dietary and health behavior in adults who watch mukbang. Methods: The questionnaire was administered on a self-written basis through online and offline formats to 800 adults (400 men and 400 women). The contents of the survey consisted of general characteristics, mukbang viewing time per week, breakfast intake frequency, preference for menus when viewing mukbang, delivery food intake frequency per week, late meal intake frequency per week, and health behavior. The subjects were divided into three groups according to mukbang viewing time. Results: The body weight of viewers was significantly higher when mukbang viewing time was over 14 hours for both men and women. In particular, based on the BMI (body mass index), those who watched mukbang for more than 14 hours were found to be overweight. People with more than 14 hours of mukbang viewing time per week were found to prefer mostly carbohydrate-rich food and meat, while those with less than 7 hours of mukbang viewing time per week showed a higher preference for vegetables and fruits. An analysis of the frequency of breakfast eaten showed that the rate of skipping breakfast was the highest for those who watched mukbang for more than 14 hours per week, and the rate of eating breakfast daily was the highest in the case of fewer than 7 hours of viewing. In the case of high mukbang viewing time per week, the frequency of food delivery and night eating was high. When mukbang viewing time was high, the viewer's interest in health was low and the frequency of exercising too was low. Conclusions: Viewers with high mukbang viewing time showed undesirable health and eating behavior. Thus, it is believed that proper nutrition education on improving eating habits and raising the awareness of correct eating habits is necessary for such viewers.

The Cell Broadcast Service is a public service that delivers information on disaster situations to mobile phones. In Korea, where mobile phone penetration is high, disaster information delivery through Cell Broadcast Service has a higher preference than other information delivery methods. However, since it consists only of text messages, disaster information is not delivered normally to the information vulnerable class compared to the general public. To compensate for this, a disaster information delivery application using Cell Broadcast Service was proposed and research was conducted. If research like this paper continues and Cell Broadcast Service become a service that transmits various disaster-related information considering the information vulnerable at home and abroad, it will provide the effect of reducing damage to disasters through rapid and accurate response.
This is a study on the subjectivity of audiences about preference of documentaries on TV. Accordingly, Q-methodology was used for this study. As a result, audiences' various characteristics by preference types were able to be found. The individual characteristics were classified into three styles: an entertainment-oriented style pursuing enjoyment, public and society interest-oriented style pursuing public purpose, and culture-oriented style pursuing artistic value of documentaries in order. It could be inferred from the classification of preference styles that unlike the past, the choice of TV broadcasting of audiences was shifting from the passive and media-dependent form to positive form. Therefore, the research and development of content delivery and production in the multi-media and multi-channel digital broadcasting era should be focused on not only the content itself but also an audience-centered service development model reflecting audiences' desire and hope.
The aims of this study were to investigate usage status, menu preference, quality evaluation and satisfaction of home-delivered meal box for children from low-income families in Chungcheongbuk-do, Korea. A total of 320 children and their guardians who had received home-delivered meal boxes participated in 2015. A total of respondents (62.2%) were children and teenagers, and 37.8% were guardians. The 47.7% of children and 43.8% of guardians were using the home delivery service more than one year. Most of the children and guardians answered 'eat almost', 'eat all meals' served meal box, 75.3%, 81.8%, respectively. After receiving the meal box at home, 35.2% of children consumed meals within 1~2 hours, whereas 32.8% of the guardians were ate within 2~6 hours. It was founded that 'throw away leftovers' was the highest and followed 'give it others' in a way to treat leftovers. The results of preference survey on meats, seafood, showed that 'chicken nugget' (4.07) and 'stir-fried fish cake with vegetable' (3.63) were the highest points for children, whereas 'grilled LA beef ribs' (3.98) and 'stir-fried anchovies' (3.72) were the highest point for guardians. 'Seasoned leaves marinated in soy sauce' was the highest preference among vegetables and another dish for respondents. Frozen products were the most preferred types of meal boxes on the menu. In the quality evaluation of home-delivered meal box, although satisfaction with service and packaging of the meal box were high, the satisfaction of food quality was relatively low.

The purpose of this study was to investigate the differences among internet and TV home-shopping perceived risk segments in regard to clothing shopping orientations and purchase intention. The subjects used for the study were 290 female consumers aged from 20 to 40 living in Seoul. The study used factor analysis, cluster analysis, ANOVA, Duncan test, and $\chi^2-test$. The results showed that the Internet and TV home-shopping perceived risks consisted of 9 factors: Products uncertainty risk, Internet shopping mall trust risk, account-related risk, delivery risk, social risk, size risk, exchange/return risk, TV watching-related risk, and price risk. The cluster analysis showed that there were five groups segmented: Size risk/TV watching risk group, Social risk/Internet trust risk group, Return risk/TV watching low-risk group, Delivery risk/product trust group, and Product risk group. The clothing shopping orientations were classified by 5 factors: Planned shopping, pleasure shopping, sales/fashion oriented shopping, time saving shopping, and credit card preference/in-store oriented shopping. The results showed that the five segmented perceived risk groups differed in regard to clothing shopping orientations, purchase intention, and demographics. Further group differences and implications of the results were discussed.
A phenomenological study was conducted to investigate the experiences of mothers pregnant via in vitro fertilization (IVF). Sample of nine mothers participated. Ten theme clusters emerged when the formulated meanings were organized into categories. During the infertility period, the participants were subject to self- depreciation, envy, anxiety, and depression. It changed their priorities in life from a job-oriented life to one where having a baby was the most important thing. After trying numerous alternative therapies, IVF became their last hope in having a baby. Since the success rate for IVF is low (only 20-30%), the participants for the treatment were overwhelmed with uncertainty, and it led to further anxiety, depression and despair. Success of pregnancy gave them extreme satisfaction, but they became very cautious in their day-to-day life because of their fear of abortion and early delivery. Some were even worried about the side effect of IVF during the pregnancy. Finally, the delivery of the baby gave them relief from the obligation of having a baby. Women did not have any difficulties in rearing a "test tube baby" except in the case of twins. Most women had no ethical difficulty in having a baby by IVF. However they did not wish this information to be revealed to other people. They again turned to IVF to have a son(s) when the resultory child(s) was a daughter(s). This is because of the strong preference for sons in Korean society.
Available-to-promise (ATP) exhibiting availability of manufacturing resources can be used to support customer order promising. Recently, one advanced function called Capable-to-promise (CTP) is provided by several modern APS (advanced planning system) that checks available capacity for placing new production orders or increasing already scheduled production orders. At the customer enquiry stage while considering the order delivery date and quantity to quote, both ATP and CTP are allocated to support order promising. In particular, current trends of mass customization and multi-side production chain derive several new constraints that should be considered when ATP/CTP allocation planning for order promising - such as customer's preference plants or material vendors, material compatibility, etc. Moreover, ATP/CTP allocation planning would be executed over a rolling time horizon. To utilize capacity and material manufacturing resource flexibly and fulfill more customer orders, ATP/CTP rolling planning should possess resource reallocation mechanism under the constraints of order quantities and delivery dates for all previous order promising. Therefore, to enhance order promising with reliability and flexibility to reallocate manufacturing resource, the ATP/CTP reallocation planning mechanism is needed in order to reallocate material and capacity resource for fulfilling all previous promised and new customer orders beneficially with considering new derived material and capacity constraints.

In most cases, the routing policy of networks shows a preference for a static one-to-one mapping of communication pairs to routing paths, which offers adversaries a great advantage to conduct thorough reconnaissance and organize an effective attack in a stress-free manner. With the evolution of network intelligence, some flexible and adaptive routing policies have already proposed to intensify the network defender to turn the situation. Routing mutation is an effective strategy that can invalidate the unvarying nature of routing information that attackers have collected from exploiting the static configuration of the network. However, three constraints execute press on routing mutation deployment in practical: insufficient route mutation space, expensive control costs, and incompatibility. To enhance the availability of route mutation, we propose an OpenFlow-based route mutation technique called Polymorphic Path Transferring (PPT), which adopts a physical and virtual path segment mixed construction technique to enlarge the routing path space for elevating the security of communication. Based on the Markov Decision Process, with considering flows distribution in the network, the PPT adopts an evolution routing path scheduling algorithm with a segment path update strategy, which relieves the press on the overhead of control and incompatibility. Our analysis demonstrates that PPT can secure data delivery in the worst network environment while countering sophisticated attacks in an evasion-free manner (e.g., advanced persistent threat). Case study and experiment results show its effectiveness in proactively defending against targeted attacks and its advantage compared with previous route mutation methods.

The orders of Design-Build Delivery System (DBDS) in a large and public construction project have been increasing. Single Source Responsibility (SSR) for design and construction, which contributes to quality improvement of design and construction, has been performed. The DBDS performs SSR for design and construction, but, it has not maximized effect because of the dissatisfied alternative analysis procedures which are based on constructability evaluation and the information system in the design step. In this research, Constructability Evaluation Factors (CEFs) that must be evaluated, investigated, and reflected in the basic design step for design-build projects. The CEF proposed and the business process of each conductor has been systematized. To propose constructability evaluation factors, first classify drawing information by the constructability evaluation sphere. CEFs must be proposed to evaluate factors according to interference among work items. Second, applicable CEFs must be classified by preference ranking and weight. Third, the values of constructability factors in accordance with building elements and work items, need to be calculated. Finally, the CEFs proposal will support rational decision making, design cost reduction, and quality improvement through the values for constructability of building elements and work items.
This study examined the general housing awareness and awareness on house sharing of college students who are present residents as well as potential residents of shared houses. To achieve this purpose, structured questionnaires were used as a survey tool to understand students' awareness on housing and opinions on house sharing including a range of space sharing, preferences on house mates, and demands on services and facilities. The survey was conducted of college students in Busan, and the data were analyzed by the PASW Statistics 18.0 program. The findings of this study are as follows: 1) The housing awareness was categorized into seven factors by factor analysis. The subjects valued 'personality factor' in the housing awareness. 2) Regarding preference of house mate type, participants preferred a person who has similar lifestyle and in the same gender. 3) As for the space sharing, the subjects didn't want to share a bathroom and shower. Also, they preferred medium or large scale dormitory layout type to small sized apartment type. 4) The most positive aspect of house sharing was 'Reduction of rental and maintenance cost'. On the other hand, 'Difference of daily life pattern' was the most negative aspect of house sharing. 5) In case of services and community spaces, they preferred 'delivery storage service' and 'coin-operated laundry facility'.
