호텔인재의 인재가치제안(EVP)과 인재개발요소가 경력성공에 미치는 영향에 관한 연구

The purpose of this study is to give insights and practical suggestions for hotel operations to establish a Talent Development System for supporting talent acquisition and talent retention, identifying the values of the Employee Value Proposition(EVP) and the Talent Development Elements influencing organizational career success. The result of the analysis showed that the EVP factors `interesting job` and `reliable company` affect `career success.` The Talent Development Elements such as `mentoring` and `education and training` also affected `career success.` The moderation effect by job grade of the EVP has not been found in this research, however, the moderation effect by job grade of the Talent Development Elements showed that the `assistant manager group` recognizes `education and training` and `mentoring` as the influencing drivers for `career satisfaction,` while the `manager above group` identifies `job rotation` as the main requirement for `career satisfaction.` The implications of the research are as follows; Firstly, systematic career development programs need to be secured for the career development of managers based on the thorough analysis of their job profiles. Secondly, a mentoring program needs to be reinforced in the organization to assign tasks through a pair, mentor and mentee, which will involve selecting common tasks and solving them with the collaboration of the pairs. Third, managers and above need to be provided with multi-job tasks or job rotations for their career development or promotion, while assistant managers are focused on education and training by completing required leadership modules.

본 연구의 목적은 국내 자생식물인 소리쟁이 (Rumex crispus)로부터 살초활성물질을 분리하고, 그화학구조를 구명하는데 있다. 소리쟁이 메탄을 추출물의 유체에 대한 GR50값은 935 ㎍ g-1이었다. 메탄을 추출물을 에틸아세터이트로 분획한 분획층을 대상으로 activity-directed bioassay를 수행하여 가장 살초활성이 높았던 ECDA 분획물을 얻었다(GR50값, 53㎍ g-1). ECDA 분획물을 GC-MS, ¹H-NMR, 13C-NMR로 분석한 결과 분자량 186.2, 화학구조식 C11H6O₃, furanocoumarin 골격구조를 하고 있는 2H-furo[2,3-H]-[1]-benzopyran-2-one(angelicin)으로 밝혀졌다. Angelicin의 물피(Echinochoa crus-galli), 바랭이(Digitaria ciliaris), 자귀풀(Aeschynomene indica)에 대한 seed bioassay 결과 각 식물에 대한 GR50값은 426, 66, 216㎍ g-1이었다. 본 연구의 결과는 소리쟁이 유래 신규 살초활성물질 angelicin은 향후 새로운 제초제 개발을 위한 선도물질로 이용될 수 있을 것이라 판단된다. The objective of this study was to isolate a herbicidally active compound from curly dock (Rumex crispus), a native weed in Korea and to identify its" chemistry. The GR50 value of methanol extracts which is determined by a seed bioassay using rapeseed (Brassica napus) seedlings was 935 ug g-1. Activity-directed isolation of ethylacetate extract led to the isolation of ECDA fraction with GR50 value 53 ug g-1. Based on data of GC-MS, ¹H-NMR and 13C-NMR, the chemical structure of ECDA was determined as 2H-furo[2,3-H]-[1]-benzopyran-2-one which is known as angelicin. The GR50 values of angelicin to barnyardgrass (Echinochloa crus-galli), southern crabgrass (Diguaria ciliaris), and indian jointvetch (Aeschynomene indica) were 426, 66 and 216 ug g-1, respectively. Our results suggest that angelicin could be used as a lead compound for the development of new herbicides.

yLRC composite column is developed for reducing the term of works, improving capacity of construction with omission of the form working and reinforcement and having an excellent section-performance with composite behavior of concrete and steel. In this study, compressive strength tests on yLRC (Reinforced Concrete with y-shape steel sheets and L-shape steel angles) composite column reinforced with in-braces are performed. Axial compressive strength tests of Non-reinforced yLRC column had been performed, however, the columns showed a sudden reduction of load even though small displacement. So, these tests are performed to raise time and displacement until the failure point and examine the suggested equation to calculate the compressive strength of yLRC composite column. The main variables are 1) comparison of column with and without in-braces, 2) a variety of in-braces, 3) the number of in-braces, and axial load test on these 9 specimens is performed. With test results, the mechanical properties on the compressive strength and structural behavior of reinforced yLRC composite column are analysed and the suitability of the suggested equation is examined.

The present paper relates to a study on automotive non-contacted torque sensor for MDPS or EPS, which includes Hall IC, circular permanent magnet and apparatus of magnetic shield using soft ferromagnetic material and is mounted to torsion bar connected steering column ? shaft assembly. Torque sensor can be promptly and precisely measured by change of magnetic field to loaded twist torque when a driver operates steering wheel and can be obtained better durability then contacted type such as using strain gauge or potentiometer.
