  • In the major operation sections of the urban railway, there has been habitual delay, and delay propagation; another problem is the increase of crowds and of inconvenience to passengers. The urban railway has different characteristics from rural railways, such as uncertainty of demand and irregularity of train operation. In urban railways, recently, operators manage quality indicators of service using operation results, such as the delay of train operation and the congestion of trains. However, because the urban railway has characteristics in which demand, passenger behavior, and train operation mutually affect each other, it is difficult to express the quality of service that passengers actually feel. In this paper, we suggest a quality indicator of service from the viewpoint of passengers, and present a demand responsive multi-train simulation method to predict dynamic dwell time and train operation status; we also use simulation results to consider changes in the quality indicator of service.

  • This study investigated the rates and reasons for breakfast skipping according to gender, age, and lifestyle related factors in Korean adults. The survey was conducted using questionnaires and the subjects included 1148 male and female adults aged 19-64. The rate of breakfast skipping (frequency of eating breakfast under 4 times/week) was 41.20% of the total subjects. The breakfast skipping rate of the male subjects was significantly higher than that of the female subjects (p < 0.001). As age and household income decreased, the breakfast skipping rate increased. Residents in small cities more frequently skipped breakfast than those in larger cities. The main reason for breakfast skipping was "lack of time for the preparation and consumption of food" and this reason was especially higher for office workers and younger adults among the participants. In addition, the proportion of habitual breakfast skippers increased with age. Among the answers regarding the person who prepares breakfast in their households, the highest proportion was for "family members" in the males and "myself" for the females. Of breakfast skippers, 77.63% answered that they consumed breakfast substitutes such as breads, dairy and fruits/vegetables. To summarize the results, the gender, age and lifestyle factors of adults were significantly related to the rates and reasons for breakfast skipping. Therefore, to reduce breakfast skipping in Korean adults, a differentiated nutritional education approach relative to gender, age, and lifestyle is needed along with the development of balanced breakfast substitutes.

  • Immigration of Koreans to the United States has increased since the 1960's. Adjusting to life in the United States produces a great deal of stress for immigrants. Despite better economic opportunites, many see the U.S. culture as threatening to their family and cultural values. Differences in culture, language, expectations and social behavior can lead to misunderstandings between health care providers and clients. These misunderstanding can leaf to frustration on the part of each. The ultimate result of this is that often Korean-immigrants do not get their health care needs met and stress response symptoms can lead to disease if there is no appropriate care. To determine the health care needs and concerns of Korean-Americans, a health needs assessment is needed. Appropriate and adequate information about the health care needs of these individuals is important as it relates to American policy changes allowing greater numbers of immigrants to enter the U.S. The purpose of this prospective study was to describe Korean-American stress response. This study focused on the primary presenting problems for which subjects reported having sought care. These included a variety of stress-related symptoms, including peripheral manifestations, cardiopulmonary symptoms, central-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, depression, anxiety, emotional irritability and cognitive disorganization. Of the 300 subjects who entered the study, 80% (N=223) completed the questionnaire in full. Demographically, the percentage of females and males was 50% each and they ranged in age from 20 to 69 years. Ninety percent of the subjects were highly educated, 25% owners of business, 25% white collar professionals, 15% employed in sales or as skilled /unskilled labor, 30% had no occupation : and 5% were housewives or students. The SOS inventory is designed to quantify self-perception of behavioral, cognitive, and physiological components of the stress response. It consisted of 94 items divided into 10 subscales. The result of this study are as follows : The total mean 505 of all subjects (N=223 was .8129 ; the mean 505 for male(N=114) was .7665 and for females, (N=108) .8594. The level of symptoms for central-neurologic and muscle tension was higher for than for males. The highest stress response of all subjects was emotional irritability symptoms(1.0644) : the lowest stress response of all subjects was peripheral manifestation symptoms.

  • We are investigated about the state of the working circumstances and infection blocking facility within Metropolitan, Chungcheong and Gyeongsang regions in Korea. The result is as follows. The HAV vaccination rate is 35% and the HBV vaccination rate is 50% among the funeral directors. We expected that the infection risk of funeral directors was very high. Significantly, tuberculosis prevalence rate of funeral director was four times as high as the public. The wear rate of gown, mask, gloves showed relatively high than the others. The wear rate of individual protective equipments has decreased with work experience. The funeral directors have shown that there is difficult to get safe protection from infection. The personal hygiene of funeral directors and the infection blocking equipment should be strengthened institutionally. We are thought to recommend institutional support about infection management, individual protective equipment, vaccination of funeral director and guideline to avoid reversion to previous habitual behavior.

  • Why can't we be free from diverse crises threatening our lives in a high-tech future society? Disasters interrupt habitual and institutionalized patterns of behavior and bring about a kind of social shock to make people follow social and individual changes. An interesting fact revealed in the study finding is that the role of disaster management control tower was proper during the Great Flood ofthe Eulchuk Year(1925) and the unified disaster management system facilitated smooth cooperation with relevant authorities. Also, motivating disaster management organizations positively influenced organizational commitment. This implies that if we constantly ask to improve current institutions by introspecting and learning, based on historical records, we may be able to find insights for a safe society of the future.

  • This study analyzed consumer's harsh complaining behaviors and firm's reactions toward consumers' harsh complaining behavior, and investigated the differences in the firms' reactions according to the characteristics of counselors and customer service centers. In addition, this study attempted to find a strategy and provide guidance regarding consumer's harsh complaining behaviors. The results of this study are discussed below. First, consumer's harsh complaining attitudes were expressed by crude language, violent language, threats, personal attacks, and claims of a high-ranking social position. Consumer's directive, complaining behaviors were repeated on the telephone, and threats of prosecution or disclosure to the public, exposure of habitual product returns, and requests for interviews with superiorsat the representative firm were made. Second, a firm typologies according to its reaction style toward a consumer's harsh complaining behaviors were as follows: Group 1, having a neutral attitude toward consumers and preparation thoroughly regarding their demands; Group 2, having a negative attitude toward consumers and some degree of preparation toward consumers' demands; and finally, Group 3, having a positive attitude toward consumers but offering insufficient reparation regarding consumers' demands. Third, female counselors, counselors having a certified counselor's license, and those much experience working in labor work were more likely to be in Group 3. Male counselors, part-time counselors, and those having experience of many years were more likely to be in Group 2. Group 1 were more likely to have large number of workers at customer service centers, male counselors, and to have large numbers of educational training programs related to the reactions of consumers in the form of dissatisfaction, complaints, how to offer compensation for injuries to consumers, and issues related to PL(product liability). In addition, Group 1 also had more firm level welfare policies related to hight stress levels of consumer counselors and extra types of support regarding harsh consumers. However, Group 2 members were more likely to provide excessive compensation and rewards to harsh consumers. Finally, to react to consumer's harsh complaint efficiently, it was suggested that firms should not treat consumers as harsh consumers, should react to consumers' complaints sincerely, and should take precautionary management efforts as regards consumer dissatisfaction based on better quality control of products. In addition, it was deemed necessary to formulate a management strategy to train competent consumer counselors with a high quality of counselor skill, having standardized and consistent reaction guidance toward consumer complaints and thorough knowledge of compensation rules for consumer injuries and subsequent guidance.

  • Oral health knowledge, awareness and attitude towards parents of the dental hygiene students is giving a mutual influence over their children enrolled in the dental hygiene department. Therefore, the university is a situation that requires students to oral health education that can be caused by changes in attitudes and behavior, rather than a simple knowledge transfer. This study was performed to compare the differences in oral health knowledge and awareness of dental hygiene department parents. Research method was used to survey the SPSS v19.0 through the Google study has used a total of 200 in the final analysis to the National Dental Hygiene Department of the lower grades (first grade) and seniors (fourth grade), the student's parent. The results child's impact as a student in the dental hygiene department is older group were more statistically significant than the younger group. Oral Health Knowledge average of the parents of the grade your child is younger parents, older parents, cognitive average younger parents, older parents, education, whether through a child younger parents older parents, the impact is younger parents was higher in the upper grades to both parents of older parents. Therefore, the older the child the more it can be seen that grade their knowledge and habitual behavior affects the oral health knowledge and awareness of their parents.

  • In Korea, 28,641 cases of traffic accidents were caused by drunk driving in 2010. These statistics accounted for 12.62% of total number of traffic accidents. Moreover, the percentages of deaths and injuries from them were nearly 15% of those from whole traffic accidents. While police has emphasized enforcement efforts in order to reduce drunk driving, culture generous to drunk driving in addition to the absence of an appropriate intervention system for habitual drunk drivers have contributed to the increasing number of the drunk driving accidents in Korea. This study examined specific behavioral changes in drunk driving by comparing drivers' behavior pattern in non-alcoholic condition to those in alcoholic condition, using a psychomotor test and a driving simulator. In the psychomotor test measuring participants' reactions to the target stimulus, it was revealed that participants' correct responses were decreased, false responses were increased, and no responses also were increased after drinking. Furthermore, in the driving simulator performance after drinking, not only driving speed was faster but also the deviation of an accelerator pedal pressure and of the vehicle's lateral position were much increased. These results indicated that alcohol consumption would impair visio-cognitive ability and deteriorate driving safety. Finally, the implications and limitations of our findings and suggestions for the future research were discussed.

  • Purpose: The purpose is to prevent accidents by predicting disasters through the analysis of near-miss. Method: In this study, a near-miss literature review and data were collected at construction sites, and a questionnaire survey was conducted to use logistic regression analysis and decision tree analysis to classify the possibility of near-miss connection. Result: As a result of analyzing the effects of near-miss types on mental, physical, and safety habits and behaviors, the factor with a high influence on the body is the need for near-miss management, the type of job is electricity·information communication, and health status in order, and the mental factor is the construction scale The influence was high, and the factors with the highest influence on the habit behavior factors were analyzed in the order of experience, number of serious injuries, and occupation in order of illusion, inappropriate work instructions, and body parts. Through decision tree analysis, factors and patterns that affect the possibility of a near-miss being a surprise accident were identified. Conclusion: Construction site officials consider the observation of near-miss and mentally and physically. Specific management of the relevance of physical aspects to near-miss should be implemented, and a work environment in which serious accidents are reduced is expected through personnel allocation, work plans, work procedures and methods, and feedback so that inappropriate work instructions do not lead to near-miss.

  • This study was conducted to assess the dietary habits and behaviors of college students in the Northern Gyeonggi-do Region(Republic of Korea). To accomplish this, a survey was conducted to investigate the preference, intake frequency and menus of breakfast, lunch, dinner and snacks by male and female students. Most male and female students had irregular breakfasts with the main reasons for skipping a meal 'not enough time' (47.3, 45.5%) and 'irritating' (19.0, 21.9%), respectively. The principal breakfast menu for both was 'rice and side dishes'. The lunch time for male and female students was regular, and the lunch cost made up most of their spending money. The snack time of male and female students was mostly 'between lunch and dinner'. The snack menus of male and female students were 'cookies' (25.8, 19.0%), 'drinks' (18.0, 14.4%), and 'breads' (16.9, 13.2%), respectively. For male students, the reasons of snack intake were 'hunger' (46.1%), 'boredom' (15.7%), and 'habitual' (9.0%). For female students, the reasons were 'hunger' (28.2%), 'habitual' (22.4%), 'boredom' (15.5%). Half of the college students had regular delivery foods for reasons of 'hygiene', 'taste', and 'nutrition' in the order and in consideration of being the elderly. The facility foodservice was also used half of the college students for the reasons of being 'economic' (30.9, 22.6%), and 'liberated from preparing meals' (21.4, 23.8%), respectively. Both male and female students were found to have less knowledge of the facility foodservice in the elderly. Based on these results, greater efforts should be made to provide meaningful information regarding the dietary habits and behaviors of college students, especially, when elderly.
