To suggest the fundamental data for the estimation of crop evaportranspiration by the ca- lculated coefficients for estimating the radiation suitable to the different regions of korea in application of Penman equcation, the daily data such as sc(skycover), n(actual sunshine hours), N(possible sunshine hours), Rs(horizontal solar radiation) and Ra(extraterrestial solar radiation) for 10 years (from 1977 to 1986) collected from 19 meteorological stations were analysed. The results are summarized as follows : 1. The coefficients a, b and c for estimating the radiation taken by the regression method with the daily and monthly mean data of the skycover and the ratio of Rs to Ra were shown as a=0.619, b= -0.0202, c= -0.0023 and a=0.64, b=0.0377 c=0.0001 in ave- rage respectively. 2. The coefficients a and b for estimating the radiation analysed by the regression and arithmetic method from the daily ratio of sunshine hours and Rs to Ra were shown as a= 0.157, b= 0.529, and a=0.119, b= 0.726 in average, respectively. 3. The coefficients a and b for estimating the radiation calculated by the regression me- thod based on the monthly ratio of sunshine hours and radiation were shown as a=0. 319 and b= 0.557 in average. 4. The values of a and b for estimating the radiation taken from the relationship between the daily ratio of sunshine hours and radiation showed high significance level. 5. The standard deviation and the coefficient of variance between the radiation calculated from the coefficients by the regression and arithmetic method with the daily data and the actual radiation were analysed and compared to the results by the coefficients of the modified Penman method (a=0.18, b=0.55) and by those of the F.A.O inodified Penman method(a=0.25, b=0.5). The standard deviation and the coefficient of varia- nce by the regression method in this study showed the lowest value. 6. From the above results, it is suggested that regression method using the coefficients taken from the relationship between the ratio of sunshine hours and the ratio of radia- tion based on the daily data has the highest accuracy in estimating the radiation. 7. The average reference crop evapotranspiration estimating by the modified Penman me- thod using the coefficients a and b derived by the regression method from the daily meterological data was closer to the actual evapotsranspiration of grass measured in Suwon area than the estimated evapotranspiration by the modified Penman method and the F.A.O modified Penman method.

양지윤,고희원 한국기업경영학회 2016 기업경영연구 Vol.23 No.5

The purpose of this study was to examine the influential factors upon middle aged and elderly job seeker’s employment and then present political and practical strategies for the activation of middle aged and elderly’s employment. For this, data of middle aged and elderly job seeker’s in 50-85 years of age who experienced job referral service from public institutes was collected from Worknet. In order to examine the influential factors upon middle aged and elderly job seeker’s employment, descriptive statistical analysis and binary logit analysis were carried out. Demographic factors, such as gender, age, residence, education level, whether within or without vulnerable social group and factors of job hunting activity, such as preferred region, match of region, goal of job-seeking registration, wage expectation, institute of job-seeking registration were used for independent variables. Study findings are as follows: demographic features of the influential factors upon middle aged and elderly job seeker’s employment were gender, age, residence, education level and whether belong to vulnerable social group. Factors of job hunting activity which have significant effect were goal of job-seeking registration, wage expectation, institute of job-seeking registration. Unlike preceding research, the possibility of employment and permanent position was higher for middle aged and elderly job seeker’s who were female than male. Education level of under middle school makes the possibility of employment higher. There were different effects of institute of job-seeking registration on the possibility of employment and permanent position. Based on study findings, political and practical strategies for the activation of middle aged and elderly job seeker’s employment are presented as follows: It is necessary to find out practical needs of companies and job seekers through cooperation with related public institutes and networking with local companies. Based on that, it is necessary to offer the service including training, counseling and job referral service to middle aged and elderly job seekers so that they can use their experience and competence. 본 연구에서는 공공 고용서비스를 통해 취업알선을 받은 50세 이상의 중‧고령자를 대상으로 취업여부에 영향을 미치는 요인이 무엇인지 살펴보고, 취업자의 고용형태 결정요인을 함께 규명함으로써, 중‧고령자의 취업활성화를 위한 정책적 지원 및 실천적 방안을 도출하고자 하였다. 이러한 맥락에서 본 연구는 2015년 워크넷데이터 중 공공 취업알선서비스를 경험한 중‧고령자를 대상으로, 인구통계학적 요인(성별, 연령, 거주지, 최종학력, 취약계층 여부)과 구직활동 요인(희망지역, 거주지‧희망근무지역일치 여부, 희망임금, 구직등록목적, 구직등록기관)을 중심으로 중․고령자의 취업여부, 고용형태에 영향을 미치는 요인을 파악하기 위하여 기술통계분석, 이항 로지스틱 회귀분석을 실시하였다. 분석결과 인구통계학적 요인에서는 성별, 연령, 거주지, 최종학력, 취약계층 여부가 취업여부 및 고용형태에유의미한 영향을 미치는 것으로 나타났다. 구직활동 요인에서는 구직등록목적, 희망임금, 구직등록기관이 취업여부 및 고용형태에 각각 유의미한 영향을 미치는 것으로 나타났다. 선행연구와 달리 중·고령 구직자 남성의취업 및 정규직 가능성이 여성보다 낮게 나타났다. 최종학력이 중학교 이하일 때 취업가능성이 높게 나타났으며, 구직등록기관별 취업가능성 및 정규직 가능성에서 유의미한 차이가 있었다. 이러한 결과를 통해 공공고용서비스에서 제공하는 중‧고령자 일자리 중 학력을 요구하지 않는 단순노무직일자리 비율이 높으며, 기관별 구인자 및 구직자의 특성(구직등록목적 등), 알선방식에 차이가 있음을 짐작할수 있었다. 중·고령 구직자를 대상으로 공공 고용서비스를 제공하는 기관 담당자는 지역과의 네트워크 형성 및인사담당자들과의 교류를 통해 괜찮은 일자리를 적극적으로 발굴·연계하고 유관기관과 면밀한 협조체계를 이루어 중·고령 구직자와 구인자의 현황자료 및 수요를 파악할 필요가 있다. 이를 바탕으로 맞춤형 교육훈련, 상담, 취업알선 서비스를 제공하여 중‧고령자들이 자신의 경험, 전문성 등을 활용하여 일할 수 있도록 취업지원서비스를 제공해야 할 것이다.

미래신호 개념을 이용한 청년 일자리 정책 이슈 도출

양지윤,고희원 한국생산성학회 2022 生産性論集 Vol.36 No.3

In this study, we tried to derive issues of policy related to youth jobs and to indirectly perceive how the public perceives the policies promoted in relation to youth jobs. For the reason we used data containing the keywords ‘Youth Jobs’ and ‘YouthJobs’ among documents from press, Twitter, and National Petition website of the Blue House, as well as a research method of the Future sign. For the analysis of the Future sign, we referred to the research of Hiltunen(2008), Yoon(2012) and Lee(2019). The focus was on discovering weak signal that are socially important and likely to increase interest among future signals. As a result of the analysis, it was found that education and employment policies are strong signals(the first quadrant) that are common in KEM and KIM. Thererfore, they should be continuously interested because the majority of the people are currently socially interested and the public's level of sensibility is high. On the other hand policies that are weak signals but are likely to turn into strong signals are identified as health and cultural policies. It is highly likely that this will become an issue to the extent that the whole nation is interested and recognized as important in the future. The change in recognition of health and culture as important in relation to youth employment policies can be attributed to a significant change in the perception of young people about the importance of work, compensation, working environment and leisure from the past. On the other hand, policies related to finance and unemployment appeared as potential signals that were not fully issued in terms of KEM and KIM. Lastly, there was no common keyword in KEM and KIM in the fourth quadrant where the frequency was high but the rate of increase was not high. Therefore it is necessary to plan and implement not only policies that directly support youth employment but also policies that meet the needs of industrial sites and youth and that can expect long-term results. This study has significant implications in that it is possible to identify issues of high importance or interest to the public regarding youth employment through a qualitative analysis method thereby confirming the direction of national policy and fiscal input in advance. 본 연구에서는 청년 일자리 관련 정책 이슈를 도출하고자 하였으며 청년 일자리와 관련하여 추진된 정책등에 대해 국민이 어떻게 인식하는 가를 간접적으로 확인해 보고자 하였다. 이를 위해 언론사, 트위터, 청와대국민청원 사이트의 문서 중 ‘청년 일자리’와 ‘청년일자리’ 키워드가 포함된 데이터와 미래신호 연구 방법론을활용하였다. 미래신호 분석을 위해서는 Hiltunen(2008)의 연구를 기반으로 Yoon(2012)과 이홍주(2019)의 연구를 참고하여 미래신호 중에서 사회적으로 중요하고 관심이 높아질 가능성이 큰 약 신호를 발견하는 데 중점을 두었다. 분석결과 KEM과 KIM에서 공통으로 나타나는 강 신호(1사분면)인 교육과 취업 정책은 현재 대다수 국민이 사회적 관심을 두며 국민의 체감 정도가 높은 상태이므로 지속적인 관심이 있어야 할 것으로 나타났다. 반면 약 신호이지만, 강 신호로 바뀔 가능성이 큰 정책은 건강과 문화 정책으로 파악되었다. 이는 향후전 국민이 관심을 가지고 중요하다고 인지할 정도로 이슈화될 가능성이 크다. 이처럼 청년 일자리 정책과 관련하여 건강과 문화를 중요하게 인식하는 변화는 청년들의 근로, 보상, 근무환경, 여가의 중요성 등에 대한 인식이 과거와 크게 변화했기 때문이라고 볼 수 있다. 반면에 금융과 실업 관련 정책은 KEM과 KIM 측면에서본격적으로 이슈화되지 않은 상태인 잠재신호로 나타났다. 마지막으로 빈도는 높지만, 증가율이 높지 않은 상태인 4사분면에서는 KEM과 KIM에서 공통되는 키워드는 없었다. 따라서 청년의 고용, 취업에 대한 직접적인지원 정책뿐만 아니라 정책수요자인 산업현장과 청년들의 요구를 충족시키고 장기적인 성과를 기대할 수 있는 정책을 계획하고 실행할 필요가 있다. 본 연구는 정성적인 분석 방법을 통해 전 국민이 청년 일자리와 관련하여 중요하다고 생각하거나 관심이 높은 정책 이슈를 사전에 찾아내어 국가의 정책과 재정투입의 방향을사전에 확인할 수 있다는 점을 시사하였다.
