This study was conducted to establish a comprehensive grading guideline for poultry. Guidelines for sampling size and grading were determined on the basis of survey data obtained from chicken processing house. Results were summarized as follows : For application unit, most chicken processing house preferred lot unit to farm unit. Most processing house did not want the total survey method, but selection sampling. At the beginning of the grading system, chicken processing house wanted to apply the system to a particular lots for which the company requests. There were much suggestions for grading not only portion meat, but also whole chicken. Bigger processing house preferred no. $8\~12$ to be graded. Most of large-scale processing houses used more than 81 volts for stunning and cooling tanks by soaking. For shipping chicken, Large-scale processing houses used both individual and box packing while small ones only used box packing.

The use of internet is expanding globally in a rapid way. The situation is similar in Korea. The growth of internet affects the various aspects of a social system. Such an impact is not an exception in the field of survey data-collection. The internet survey method has gained a recognition as an important survey approach in the U.S and Europe. A number of Korean research organizations have already started implementing the new survey method, too. The time is quite ripe for the internet survey in Korea. However, it is hard to find ever a good literature review on the subject. This study intends to review the results of the past studies about the question of what factors influence the response rate, speed, and quality. The influencing factors incorporated in this review include six elements: personalization, the survey sponsorship, incentives, the questionaire format, prenotification, and follow-ups. Regarding there sis factors, the results of the past studies relating to the internet survey response are reviewed in a systematic way.

Objects: This study is a descriptive study to identify the factors influencing the glycated hemoglobin control in type 2 diabetes patients. Methods: This study used raw data from the third year of the National Health and Nutrition Examination Survey performed from 2015. The subjects were 285 people who were classified as type 2 diabetes patients among the 7,380 participants of the National Health and Nutrition Examination Survey. Findings: The factors influencing the glycated hemoglobin control in type 2 diabetes patients were found to be age, education level, prevalence period and sleeping time. Improvements: In type 2 diabetes patients, it is very important to have appropriate education on diabetes when they discovered the disease morbidity in the middle age rather than in the aged period and to have enough sleeping time. A practical program to help this education and training should be developed.

Self-sufficiency (SS), which is often used in the social welfare policy of the American welfare system, is an important concept in the field of social welfare and has been studied so much. Among such studies there are also studies on how the employment hope scale and the perceived employment barrier scale, which the psychological SS (PSS) consists of, affect the economic SS (ESS) for low-income job seekers in the United States. These studies are generally conducted using survey data, which are mainly analyzed by structural equation model (SEM) in the field of social science field. In the survey data, the number of measurement variables is generally large and there is a correlation between variables. In such cases, Principal Component Analysis (PCA) can be used. The purpose of this study is to compare the results of SEM and PCA on the survey data mainly dealt with in the social science field. We compare the performance of the two analyzing methods through a small simulation study. We also analyze a real survey data of the ESS and the PSS by using these two methods and compare the results.

This study investigates methodological implications of cyberspace and information technology for online survey research Online survey method provides useful methodological tools for collecting empirical data for the study of cyberspace, In terms of sampling frame , selection method, and questionnaire from four major types of the online survey research can be found: member survey visitor survey e-mail survey and the electronic survey. Online survey research with sample design(population specification error. sampling frame error, selection error) measurement (measurement instrument bias system-related processing error, nonrespone, and response bias) and research ethics (privacy and netiquette) pose important methodological issues for the survey. The realization of the technological possibilities of online survey will be possible only through a right consideration of these issues.

Despite the importance of questionnaires, little survey methodology research on questionnaire design has been conducted in Korea. The purpose of this study was to explore whether two questionnaire forms (close-ended vs. open-ended questions) about 'the most important problem in Korea' elicited similar responses. During the 2016 Korean General Social Survey (KGSS), a random half of respondents were asked the open-ended question form and the remaining half were asked the close-ended question form. While the economy is the most mentioned response (35% vs. 33.2%) to both close-ended and open-ended question forms, there is similarity in the order of highly mentioned responses if we consider that 'politics' is not provided as one of response categories in the close-ended question form. The order of second to fourth response category is crime (24.4%), education (15.4%), and poverty (6.3%) to the closed-ended question form, and politics (10.8%), crime (9.5%), and education (7.6%) to the open-ended question form. Also, the characteristics of respondents who responded with the economy as being the most important are slightly different between the two halves in terms of age, household income, and satisfaction with economic condition. Our findings suggest that we need to be careful when we adopt questions developed in other countries and to consider using survey experiments in pre-testing questionnaire items.

성공적인 창업을 위해서는 창업자 개인의 기본적인 역량뿐만 아니라 체계적인 창업교육과 학습을 통해 창업자가 되기 위한 필요역량을 습득해야 한다(최서윤, 2017). 대학생의 창업을 활성화하기 위해서는 다양한 분야를 전공하고 있는 대학생의 학문적 특성을 고려하고 그들의 전공 및 학문적 특성을 고려하여 창업교육 및 창업지원을 통해 대학생의 창업의지를 높이는 것이 필요하다(이우진 김진수 김용태, 2013). 창업의지는 창업에 대한 행위적 태도를 의미하며, 창업이라는 긴 과정의 첫 단계이고, 개인의 태도와 경험을 창업이라는 행동으로 매개하는 역할을 한다(윤방섭, 2004). 대학이 학생들에게 창업교육 및 창업공간, 멘토링, 컨설팅, 사업화를 위한 창업지원을 하고, 대학생들은 이러한 창업교육 및 창업지원을 긍정적으로 받아들일수록 창업의지가 높아져 취업이 아닌 창업을 선택할 가능성이 높아질 것이다. 조사대상은 전국의 보건계열 대학에 재학 중인 대학생이다. 자료수집 방법은 보건계열 재학 중인 대학생을 대상으로 이메일 설문지가 발송되었고, 자기보고식 작성방법에 따라 설문조사 되었다. 총735개의 설문지가 발송되었고 그 중 불성실하게 응답한 설문을 제외한 총 675개의 설문을 최종 설문으로 사용하였다. 자료수집기간은 2017년 10월 9일부터 2017년 10월 18일까지 10일간 이루어졌다. 본 연구를 수행하기 위해 수집된 자료는 IBM SPSS Statistics 22.0을 활용하여 분석하였다. 본 연구는 보건계열 대학생의 창업가 특성이 창업의지에 영향을 미치는지, 창업교육과 창업지원제도는 기업과 특성과 창업의지의 관계에서 조절효과를 미치는지를 확인하였다. 보건계열대학생의 창업가 특성인 성취욕구, 자기효능감, 위험감수성 중 위험감수성만이 창업의지에 영향을 미치는 것으로 나타났으며, 창업교육, 창업지원제도인 대학창업지원활동, 정부창업지원정책 중 창업가 특성과 창업의지 간의 관계에서 대학창업지원제도만 조절작용을 하는 것으로 나타났다.

This study analyzes the price elasticities of airline Passenger demand through the 'Stated Preference' technique which uses survey data. Because the domestic airfare has been regulated by the government. it is not easy to derive Price elasticity through the usual regression analysis with aggregate data and thus a special methodology is required for elasticity estimation. Therefore, in this study we estimated the Price elasticities of domestic air passenger demand and the modal share change rates to the alternative modes with logit model and sample enumeration method, by analyzing the survey data on air Passengers' demand behavior about the mode choice between air-rail. air-bus, and air-car. As the results, the estimated price elasticities are in the range of -0.6~-0.9, and rail is mainly chosen as an alternative mode. bus is chosen Partly, and car is barely used.
