본 연구는 난지형 마늘의 생육시기별 기온을 고려하고 토양조건을 반영하여 난지형 마늘의 재배적지를 분석하였다. 그 결과 난지형 마늘의 재배적지는 영 호남지방을 중심으로 분포되었다. 그 중 최적지와 적지로 분류된 면적이 많은 지역은 나주시 14,058 ha, 정읍시 13,845 ha, 고창군 12,278 ha, 진주시 11,055 ha, 창녕군 9,713 ha 등으로 나타났으며, 난지형 마늘 주생산지의 경우 무안군이 5,216 ha, 해남군 5,092 ha, 고흥군 3,212 ha, 신안군 2,253 ha, 남해군 958 ha로 각각 분석되었다. 그리고 토지이용조건을 추가로 고려하여 분석한 결과와 주생산지의 실제 난지형 마늘재배면적을 비교한 결과 고흥군과 신안군이 실제 재배면적과 비슷하게 분석되었으며 해남군과 무안군은 실제재배면적보다 크게 나타났고 남해군의 경우는 분석결과가 작게 나타났다. 작물 재배는 여러 가지 생육조건과 사회적 영향 등을 고려하여 이루어지므로 난지형 마늘의 실제 주생산지와 본 연구에서 나타난 난지형 마늘 재배적지는 다소 차이가 있다. 하지만 향후 우리나라에서 난지형 마늘 재배 시 본 연구에서 도출된 재배적지 분석결과를 이용하게 되면 난지형 마늘의 효율적인 재배가 가능 할 것으로 사료되며 보다 효율적인 재배적지 분석을 위해서는 차후 토양과 기온조건 외에도 농업수리 등 다른 변수들도 고려되어야 할 것으로 사료된다.

New occupational qualification system built on NCS(National Competency Standard) aimed to induce industries, the final appliers of qualification, to play a leading role in designing qualification and to spontaneously apply such qualification standard to employment and promotion so as to reinforce universality of qualification. In this study, we verified the validity of NCS level of qualification categories for 130 occupational fields by redesigning NCS-based new occupational qualification system with a focus on 7 major areas, including mechanical field, which were found to have wide-ranging social ripple effect throughout society and high acceptability in 2014. The results of study on suitability at qualification level suggested the followings: First, there is a difference in number of competency units for each qualification category, depending on area. New qualification covering 7 major areas included 15.3 competency units for each qualification category, which exceeds the number of competency units(about 10 units) in subdivided NCS. By field, some difference was found with 7.9 competency units for cultural field and 22.6 competency units for information and communication area. Second, preference above normal level was observed in the criteria, procedure and method for determining qualification redesigning. However, preference below normal level was exhibited in connection with possibility of linkage with overseas qualifications, although preference was above normal level in relation to the suitability of design/qualification level and qualification categories based on lifelong career development path within scope of NCS as the criteria for determining the redesign of qualification categories. Second, we compared NCS level and SC(Sector Council level, and the results showed that NCS level was found to be somewhat well-defined. For the qualifications with different definitions, it was deemed difficult to determine superiority between NCS level and SC level. However, majority opinion indicated that it would be desirable to follow NCS level because NCS was created through collection of opinions for a prolonged period.

This study suggested the necessity of introducing the future-oriented new industrial complex as a way to enhance the competitiveness of the industrial complex in response to the industrial ecosystem change caused by the 4th industrial revolution. To evaluate the location suitability for the new industrial complex, location indices were developed in this study. The flexibility of location and connectivity to neighboring areas of the future-oriented new industrial complexes were the focused subjects of this study. In-depth expert consultation and Delphi survey were conducted to construct an index system and to measure the indices. Afterwards, the AHP analysis was conducted to elucidate the weighting by indicators. As a result, the indicators of industrial innovation environment were the most important in the major category. In addition, the convenience of workers, especially urban environment, was analyzed as an important factor for success of the future-oriented new industrial complex. The indicators which are closely related to the concept and purpose of the future-oriented new industrial complex turned out to have the higher weight compared to other indicators. From the point of view of the developers of the industrial complexes or tenant companies, the implications for deriving suitable locations for development of industrial complexes among urban under-utilized sites are suggested. Furthermore, It is expected that the government will be able to apply the development system to stimulate the development of these new industrial complexes and to prepare guidelines for selecting locations.

The purpose of this study is to extract typical body shapes of Korean adults based on the three-dimensional Korean anthropometric data measured through 5th national anthropometric survey and to examine the suitability of the 3-D human shape data for the interior packaging. 36 three-dimensional anthropometric variables related to the design of vehicle interior were considered for the appraisal of typical body shapes. Four major factors were extracted by the factor analysis and factor scores were calculated for all subjects. Typical or standard drivers of Korean adults were selected by the minimum deviation criteria for the four factor scores with respect to 5th, 50th, and 95th percentiles, respectively. Typical drivers of Korean adults were visualized by the CATIA-HUMAN program due to the absence of proper application software for three-dimensionally scanned human body data. There are considerable differences between the anthropometric data of Korean adults and those provided by CATIA-HUMAN program, which shows that the modeling data provided by CATIA-HUMAN should not be directly applied to the ergonomic evaluation for the vehicle design. This suggests the necessity for the development of suitable software for scanned human shape data. It is also expected that the anthropometric data of typical drivers extracted from this study help design package layouts and improve the suitability of ergonomic evaluation for Korean customers.

Fiber dimensions, their derived values and chemical properties of cotton stalks (Gosypium hirsutum L), jute stick (Corchorus capsularis) and dhancha (Sesbania aculeate) have been examined to assess their suitability for paper production. Cotton stalks have a good derived values especially slender ratio, which is comparable to hardwood. The flexibility coefficient of these three non wood plants is better than hardwood. Anatomical analysis shows higher percentage of fibers and vessels than in general non wood plants. Lignin, $\alpha$-cellulose and pentosan contents in these three nonwood plants are within the range of hardwood. Neutral sugar analysis of cotton stalks, jute stick and dhancha shows that the glucose in the major sugar followed by xylose and mannose. The arabinose and galactose are present in minor amount. Alkaline nitrobenzene oxidation of cotton stalks, jute stick and dhancha wood meal exhibits that these nonwood plant lignins mainly consist of syringyl (S) and guaiacyl (V) units. The S/V ratios are 1.6, 1.2 and 2.1 for cotton stalks, jute stick and dhancha, respectively.

The purpose of this study was to analyze the impact of parental resources and parenting stress on parenting efficacy in low-income families Furthermore, in order to verify whether parental resources function as a resilience factor, a structural model was established to assess the suitability and influence of the variables. A total of 603 parents of children and adolescents between the ages of 9-18 were selected from the data from Children and Adolescents Comprehensive Status Research (2009) by the Ministry for Health, Welfare and Family Affairs. For the analyses, SPSS WIN 18.0 and AMOS 18.0 were utilized. The major results were as follows: First, the suitability of the model was confirmed with variables presenting a satisfying fit. Second, parental resources had a negative effect on parenting stress and a positive effect on parenting efficacy. Third, parenting stress had a negative effect on parenting efficacy. Finally, a test of the structural equation model supports the hypothesis that parental resources have a significant direct effect as well as an indirect effect through parenting stress on parenting efficacy. The implications for further studies and practice were discussed.
