This study was conducted to investigate the actual state of use and necessity of Korean traditional Pyebaeck foods using questionnaire. The subjects of this study consisted of 621 housewives in Daegu area. The results were summarized as follows: The most often used foods of Pyebaeck refreshments included alcoholic drinks(80.0%), Bamgoim(73.8%), Daechugoim(73.4%). The refreshments were most often purchased from caterers(39.6%), and mainly used for marriages of their brothers and sisters(33.3%). The standard number of foods prepared was 7 to 10(42.2%). The most used container for Pyebaeck refreshments is bamboo basket(30.6%). 62.0% of the respondents needed Pyebaeck refreshments and the reason for refreshment preparation was mainly “because it is a Korean tradition”(82.3%) and the reason why most respondents do not think the Pyebaeck refreshments are necessary was “it's troublesome and complicated”(41.1%). The refreshments most frequently included were alcoholic drinks(63.7%) and Daechugoim(47.0%). Most of the respondents(84.9%) said that the Pyebaeck refreshments should be improved and 48.0% said the improvement method should consider the traditional tastes, flavors and arrangements fit to modem sense. Although following the traditions of Pyebaeck refreshments itself is difficult, the concept of Pyebaeck refreshments can develop into a modern concept with new meaning if we improve and adjust it in a way fit to modem lifestyles.

Clean Development Mechanism(CDM) projects under the Kyoto Protocol have two objectives. One is to assist the Parties included in Annex I in achieving compliance with their quantified emission limitation and reduction commitments in cost-effective ways by allowing them to implement emission reduction projects in Non-Annex I countries and receive CERs, which will offset their reduction commitments. The other is to assist Parties not included in Annex I in achieving sustainable development and technology transfers through investments by Annex I countries. However, in reality, it is said that the former objective is achievable but the latter is not. In this light, this article suggests sustainability appraisal criteria applicable for Korea. Among various methodologies, we used the 'multi-attributes utility theory(MAUT)'; one of the 'multi-criteria analysis (MCA)' methodologies judged to be the most practical and relevant. Based on the guidelines of the MAUT methodology, we identified sustainability criteria that meet the guidelines. We took two tracks, the first to find the preferences of Korean experts, and the other to check foreign cases. In all, 37 preliminary criteria were suggested to Korean experts and each criterion was scored, from between 1 and 3, in terms of relevance, possibility of real improvement, easiness of data collection, and preferences. We combined foreign cases and the results of a survey conducted in Korea and selected 12 core criteria and 10 additional criteria. After that, all the criteria were converted into indicators. The indicators were applied to a CDM project for case study. We chose the "Sihwa Tidal Power Project", which is currently the biggest tidal power plant in the world. Twelve core indicators and 3 additional indicators were applied. In order to weight each indicator, the 'analytical hierarchy process (AHP)' was used. A total of 30 experts were asked to suggest weights and 21 answered. Among them, only 14 respondents were proven to meet the consistency ratio. We analyzed the 14 responses through Expert Choice and the CDM project was scored (+)53.082. In addition, sensitivity analysis was undertaken with the result of (+)44.667 to (+)65.522. As a result of this study, it was proven that this project would contribute to the sustainable development of Korea.

This study was conducted on 4th and 5th grade elementary school students in Daegu, Korea for the purpose of promoting health and proper dietary habits. A children food safety education program was developed and its effects evaluated on 4th and 5th graders (3,932 students for 4th year, 4,438 students for 5th year) at 46 elementary schools, which were under the jurisdiction of the four educational bureaus of Daegu city. Education was conducted in accordance with an education design plan, of which there were two goals, including know the contents of 'special act on children's dietary life safety management' and 'practice proper hand-washing'. 'Special act on children's dietary life safety management' was explained, and the education curriculum included proper hand-washing for prevention of food poisoning, quality certification mark on children's favorite foods, harmful foods such as unsanitary and adulterated foods, and green food zone. Flash songs, PowerPoint, 'glitter burger' notice note, and banner were used as education media. It was found that the awareness level of items related to 'special act on children's dietary life safety management' increased significantly after education (p<0.001). 'Necessity of nutrition education and children's food safety' also increased significantly (p<0.05) after education. Lastly, children answered that they washed their hands more often after education (62.9%) than before (60.7%).

Hacking has raised many critical issues in the modern world, particularly because the size and cost of the damages caused by this disruptive activity have steadily increased. Accordingly, many significant studies have been conducted by behavioral scientists to understand hackers and their practices. Nonetheless, only qualitative methods, such as interviews, meta-studies, and media studies, have been employed in such studies because of hacker sampling limitations. Existing studies have determined that intrinsic motivation was the dominant factor influencing hackers, and that their techniques were mainly acquired from online hacking communities. However, such results have yet to be causally proven. This study attempted to identify the causal factors influencing the motivational and environmental factors encouraging hackers to learn hacking skills. To this end, hacker community members using the theory of planned behavior were observed to identify the causal factors of their learning of hacking skills. We selected a group of students who were developing their hacking skills. The survey was conducted over a two-week period in May 2015 with a total of 227 students as respondents. After list-wise deletion, 215 of the responses were deemed usable (94.7 percent). In summary, the hackers were aware that hacking skills are considered socially unethical, and their attitudes toward the learning of hacking skills were affected by both intrinsic and extrinsic motivations. In addition, the characteristics of the online hacking community affected their perceived behavioral control. This study introduced new concepts in the process of conducting a causal relationship analysis on a hacker sample. Moreover, this research expanded the discussion on the causal direction of subjective norms in unethical research, and empirically confirmed that both intrinsic and extrinsic motivations affect the learning of hacking skills. This study also made a practical contribution by raising the educational and policy response issues for ethical hackers and demonstrating the necessity to intensify the punishment for hacking.

This study was to investigate the knowledge of Korean festival foods and the acculturation of American main traditional occasions among Korean American housewives residing in the New York and New Jersey area. Out of 400 questionnaires, the 271 respondents were taken. Of the respondents, 77.1% demonstrated the interest in Korean festival foods. The most important Korean festivals were Chusuk (52.0%), Sulnal(46.9%) and Daeborum (1.1%). In order to make the Korean festival foods to be international foods, the most vital factor was taste and flavor (39.5%), cooking method (34.7%), preservation (10.3%), sanitation (8.1%) and nutrition (7.4%). American Thanksgiving Day was the most important occasion among the Korean American housewives. The factors that keep the American traditional occasions were related to whether the respondents had an occupation or the length of stay in the U.S.A. But in case of Korean festival foods, the factors cannot be applied. On the contrary, they do still keep the tradition and the interest of Korean festival foods in U.S.A. As a result of that, the Korean festival foods in the U.S.A. are systemized for the preservation and popularization for the coming Korean generation.

The purpose of this study was to examine dental hygiene students' achievement motivation and factors affecting dental hygiene students' achievement motivation by the general characteristics of subjects in this study. The subjects in this study were 450 who were selected by convenience sampling from three different three-year-course colleges. After a survey was conducted, the answer sheets from 421 respondents were analyzed. The collected data were analyzed, which made use of t-test, ANOVA and Kruscal-Wallis test. The findings of the study were as follows. 1. The dental hygiene students investigated got 3.34 in achievement motivation. They got the highest score of 3.78 in the item 'I perform what I have to do with a sense of responsibility.' and they got the lowest score of 2.67 in the item 'I like to do something risky.' 2. Concerning links between their general characteristics and achievement motivation, the students whose academic year was higher(p<0.001) and who had more clinical practice experiences (p<0.01) were better motivated than their counterparts. As to connections between achievement motivation and expected post-graduation length of service, those who replied that they planned to find another job after getting married were better motivated(p<0.05). Regarding relationship between achievement motivation and a will to work abroad, the students who had a stronger will to work abroad were better motivated. 3. As a result of checking the influence of their general characteristics on achievement motivation, stronger motivation was found among the students whose academic year was higher(p<0.01), who intended to work until marriage(p<0.01) and who didn't plan to keep working after marriage(p<0.05) when the other variables were controlled. Therefore dental hygiene students should be taught to look at things positively when they enter college, and they should also be educated to become progressive to keep working for their lifetime instead of just getting a temporary job after graduation.

The purpose of this study was to evaluate smoking patterns, oral health behavior and perception of dental healthcare of military personnel in the South Korea Army. All 367 subjects were surveyed by the structured questionnaires with convenience sampling method. The questionnaires were consisting of 22 items. Depending on the conditions of military training, the distribution and differences of smoking patterns and oral behaviors were evaluated by frequency test, Weighted Kappa, Paired t-test and ANOVA. The differences of oral health perception on smoking were demonstrated by Mantel-Haenszel Chi-square test. In addition, Generalized Estimating Equation (GEE) was used to estimate the effects of oral behavior for the conditions of military training and smoking. The number of cigarette during military training period was similar to that during non-military training (p=0.109). The perception of smokers such as smoking effect on oral health, oral health and systemic health, and need of education for smoking cessation was significantly lower than non-smokers (p=0.0095, p=0.0007, and p<0.0001). The probability that toothbrush frequency per day was only one was associated with higher during military training period than non-military training (OR=9.29, 95% CI 5.05-17.07). Moreover, the probability that hours of toothbrush were less than one minute was associated with higher during military training than non-military training (OR=2.19, 95% CI 1.78-2.71). To improve knowledge, attitude, and behavior of oral health for the members, the army needs to develop oral health education and tobacco cessation programs. In particular, motivation and practice for oral health care are required to improve poor oral health behavior during the military training.

The purpose of this study was to examine the awareness of dental patients using dental institutions about dental hygienists in an effort to help educate dental hygiene students to have the right image of dental hygienists. And it's also meant to provide education for dental hygienists to develop their own capabilities, attitude and values to render quality medical services to patients. The subjects in this study were the patients who visited dental clinics and hospitals to receive treatment. A self- administered survey was conducted from March 5 to April 13, 2010, in consideration of their general characteristics. The answer sheets from 204 respondents were gathered, and 197 answer sheets were analyzed except seven incomplete ones. A factor analysis was carried out to find out their general characteristics, and independent-samples t-test and one-way ANOVA were utilized to get statistical data on mean and standard deviation. A SPSS 12.0 program was employed to analyze all the collected data. And it's found that the largest number of the patients thought that the main duty of dental hygienists was to give treatment to patients, and they took a favorable view of their services. They weren't well aware of the process of nurturing dental hygienists and their curriculum, and they put a relatively strong confidence in their treatment and had relatively favorable experiences with them.

The aim of this study was to analyze factors related to xerostomia in adults aged 30 years and over. The data were analyzed using the t-test, one-way ANOVA and multiple linear regression analysis in the SPSS version 12.0 program. The results were as follow. 1. The respondents who were older than 51 years old, unemployed and had less than 3 million won of average monthly income were more aware of xerostomia (p<0.05). 2. The respondents who answered poor and moderate for their general and oral health and the group with duplicate medication and comorbidity were more aware of xerostomia (p<0.05). 3. The respondents that had problems in chewing, communication, ordinary activities and complained of pain discomfort and suffered from anxiety depression were more aware of xerostomia (p<0.001). 4. The respondents that answered frequent dryness on their skin, eyes, lips, and nasal mucosa were more aware of xerostomia (p<0.001). 5. Xerostomia showed highest correlation with quality of life ($\beta$=0.436) followed by the number of medications ($\beta$=0.239), sense of entire body dryness ($\beta$=0.200), feeling of hopelessness ($\beta$=0.160) and number of oral mucosa disease symptoms ($\beta$=0.099) (p<0.05). According to the results of the study, xerostomia may cause deterioration in quality of life. Thus, it is advised to improve the patient management system among dental professions to prevent various complications caused by xerostomia and conduct regular health education on the cause and management method of xerostomia.
