본 연구는 NCS 기반으로 개편된 미용사(피부) 검정형 자격과 과정평가형의 자격시험에 관한 선행연구의 체계적 문헌 고찰을 통해 국가기술자격 미용사(피부) 종목 과제 및 평가방법에 대해 비교·분석 하였다. 검정형 자격은 암기 위주의 이론시험과 단순 기능 반복을 통한 작업능력을 기반으로 평가가 이루어져 자격과 일이 상호 연계되지 않고 있고, 과정평가형 자격은 상대적으로 시험 집행을 시작한 기간이 짧은 상태로 시행기관에서의 자체 내부평가의 신뢰성 저하 문제가 지속적으로 나타나고 있다. 향후 현재 평가에 반영되고 있지 못하는 다양한 능력 단위를 적용하여 실기시험 평가 항목에 포함할 수 있는 상위자격의 신설 및 실기시험 평가방법 개선 등을 통해 현장과의 연계성을 제고시키고 관련 분야의 현장 적응 및 재교육 시간 단축 등의 자격제도 혁신이 필요한 것으로 사료된다.

본 연구는 Cakewalk by Bandlab(과거의 Sonar)의 대표적인 가상악기인 TTS-1의 접근성을 평가하고 개선방안을 제안하기 위한 목적으로 수행되었다. 본 연구는 소프트웨어 개발자의 관점에서 스크린리더 사용자가 TTS-1을사용하여 NCS의 [가상악기 에디팅하기] 능력단위 요소를 수행하기 위한 접근성이 평가되었고, 기본 접근성이 없는 기능들은 센스리더와 MIDI 기능을 활용하여 확장된 접근 방법을 모색하였다. 본 연구결과, 스크린리더 사용자가 TTS-1을 사용하여 정안인과 동등한 수준의 작업은 가능하나, 센스리더와 MIDI를 활용한 별도의 접근방법을 사용해야만 하는 것으로 나타났다. 이 결과를 통해, 스크린리더 사용자가 보다 효율적으로 작업할 수 있는 개선방안이 제안되었다.

본 논문은 우리나라 기업들의 성과에 대한 기업들의 고용, 인적자원개발, 노사관행의 시행이 미치는 영향력에 대하여 분석하였다. 분석을 위한 자료는 한국노동연구원(KLI)의 2017년 7회차 사업체패널 조사로 수집된 2,868개 기업에 대한 자료를 활용하였다. 기업의 성과는 전년도 영업이익을 대상으로 하였다. 고용은 신입사원의 공개채용여부, NCS직무능력에 대한 평가여부, 핵심인력 확보 프로그램 실행여부를 포함하였다. 인적자원개발은 재직자 훈련 실시여부, 직무능력향상도 평가여부, 저성과자 관리프로그램 시행 여부, 근로자 경력계획 여부, HRD에 직무분석 활용여부로 구성하였다. 노사관행에는 육아휴직 보장, 출산휴가에 대한 보장과 보육시설 지원 여부를 포함하였다. 분석방법은 영업이익의 흑자 및 적자 기업의 두 집단에 대한 이항 로지스틱 회귀분석을 사용하였다. 분석결과 기업의 성과에 대해 고용, 인적자원개발, 노사관행의 영향력을 확인할 수 있었으며, 기업 차원에서 성과를 높이기 위한 고용 및 인적자원 개발, 노사관행 관리의 시사점을 논의하였다.

Background: Clinical spectrum of immunoglobulin M (IgM) monoclonal gammopathy varies from IgM monoclonal gammopathy of unknown significance (IgM-MGUS) to hematological malignancies. We evaluated the clinical features, electrophysiological characteristics, and prognosis of patients with peripheral neuropathy associated with IgM monoclonal gammopathy (PN-IgM MG). Methods: We retrospectively evaluated 25 patients with PN-IgM MG. Peripheral neuropathy was classified as axonal, demyelinating, or undetermined, based on electrophysiological studies. We classified the enrolled patients into the IgM-MGUS and malignancy groups, and compared the clinical and electrophysiological features between the groups. Results: Fifteen patients had IgM-MGUS and 10 had hematologic malignancies (Waldenström's macroglobulinemia: two and B-cell non-Hodgkin's lymphoma: eight). In the electrophysiological evaluation, the nerve conduction study (NCS) criteria for demyelination were met in 86.7% of the IgM-MGUS group and 10.0% of the malignancy group. In particular, the distal latencies of the motor NCS in the IgM-MGUS group were significantly prolonged compared to those in the malignancy group (median, 9.1 ± 5.1 [IgM-MGUS], 4.2 ± 1.3 [malignancy], p = 0.003; ulnar, 5.4 ± 1.9 [IgM-MGUS], 2.9 ± 0.9 [malignancy], p = 0.001; fibular, 9.3 ± 5.1 [IgM-MGUS], 3.8 ± 0.3 [malignancy], p = 0.01; P-posterior tibial, 8.3 ± 5.4 [IgM-MGUS], 4.4 ± 1.0 [malignancy], p = 0.04). Overall treatment responses were significantly worse in the malignancy group than in the IgM-MGUS group (p = 0.004), and the modified Rankin Scale score at the last visit was higher in the malignancy group than in the IgM-MGUS group (2.0 ± 1.1 [IgM-MGUS], 4.2 ± 1.7 [malignancy], p = 0.001), although there was no significant difference at the initial assessment. Conclusions: The risk of hematological malignancy should be carefully assessed in patients with PN-IgM MG without electrophysiological demyelination features.

KRRI (Korea Railroad Research Institute) is developing a bimodal tram since the 2003s. The vehicle will be used in the public transportation system. The bimodal tram has the advantages of both bus and train. Bus system has the advantages of flexibility of the routes delivering passengers to the destination and easy accessibility. Train is to meet the scheduled arrival and massive public transportations. The vehicle is the rubber tired tram and is all wheel steered single articulation. The propulsion system is configured by CNG hybrid system. The length of the vehicle is 18m. The vehicle lanes will be marked with permanent magnets that are buried in the road. The vehicle can be automatically operated by navigation control system (NCS). In this paper, we introduce the driving system of the bimodal tram which is developed by KRRI.

The domestic professional engineer qualification system has been changed after the enactment of the law in 1963. However, the domestic professional engineers have been unaccepted and unrecognized internationally. In addition, the domestic professional engineer system is operated in accordance with the individual laws of each ministry, but the official qualification examination is conducted by the Human Resource Development Service of Korea. Thus, the domestic professional engineer system has many problems in system itself and operating. In this research, we compare the domestic qualification system with the systems of other foreign countries, and propose how to improve the qualification system. This study limits the scope to the qualification examination for P·E. We suggest 3 ways to improve the qaulification examination; (1) The structure of the qualifications, (2) The testing method, and (3) The unification of the qualification system and operation.

Dicyclohexyltin(IV) complexes $Cy_2SnX (X = O,\;S,\;(Me_2NCS_2)_2)$ have been prepared and characterized by means of elemental analysis, cryoscopic data, and IR spectroscopy. X-ray structure determination for $Cy_2Sn(S_2CNMe_2)_2$ (monoclinic; P2/c;a = 8.992(1), b = 6.688(1), c = 19.453(2) ${\AA},\;{\beta}$ = 96.556(7) ; R = 0.041) has shown that the molecule is $C_2$-symmetric with both dithiocarbamate ligands bonding in anisobidentate mode and the local geometry around the hexacoordinate Sn(IV) atom is a distorted octahedral arrangement with the two cyclohexyl groups in trans position. The physical and chemical properties measured suggest polymeric and trimeric structures for $Cy_2SnO\;and\;Cy_2SnS$, respectively.

Recently perovskite materials with much cheaper cost and marvellous optoelectronic properties have been studied for next generation LED display devices overseas. Technology development trends of inorganic $CsPbX_3$(X=halogen) based LEDs (PeLEDs) with assumed high stability were investigated on literature worldwide. It was found that syntheses methods of these nanocrystals (NCs, mainly quantum dots, QDs) made great progress. A new room temperature synthesis method showed outstanding PL (photoluminescence) properties such as high quantum yield (QY), narrow emission width, storage stability comparable with, or often exceeding those of conventional hot injection method and CdSe@ZnS type inorganic colloidal QDs. PeLEDs with shell layers might be more promising, indicating urgent real research start of this solution processing technology for small businesses in Korea.

If examining utilization by completion of National Competency Standards development, efforts are made so as to organize curriculum matched to education or training and perform subjects based on competence unit educationally in specialized high schools, colleges and university. However, National Competency Standards is insignificantly utilized in enterprises and on the spot due to characteristics of occupation type and diversity of process. This thesis intended to measures of safety efficiency improvement of final enterprise through the human resources assessment system of National Competency Standards based enterprise. Therefore, various methodologies were introduced and results of analysis by Balanced ScoreCard method were suggested for policy measures improving final safety efficiency. The results of this analysis are expected to make contribution to improving the effectiveness of the government's industrial safety and health policies through the establishment of systematic safety and health systems according to the risk level of individual business.
