This study is to propose an 'education-training-certificate of qualification' design of fashion accessories production, which can be applied to education in universities and individuals. It is based on the National Competency Standards (NCS), which was developed through the '2013 National Competency Standards Development Project' for the fashion accessories production. FGI (Focus Group Interviews), which is a research methodology, is carried out on target groups of educational experts and specialists in the field of fashion accessories production. Through this, five courses were suggested; first, 'fashion accessories design' course was proposed for the education and training of 'design development' and 'development of raw materials'. Secondly, 'fashion product production' course was proposed for the education and training of 'production of samples'. Thirdly, 'fashion product manufacture and planning' course was proposed for the competency element units: 'calculation of cost', 'determination of mass production model and price', 'planning of the main manufacturing process' and 'ordering of raw materials'. Lastly, 'mass production of fashion products' course and the 'field practice of fashion product manufacture' course were proposed for the competency element units: 'planning for mass production', 'preparation for mass production', 'mass production' and 'inspection of completed products'. In addition, a new certificate of 'technician of fashion accessory production' was proposed in order to test qualified skills for the fashion accessories production. The test is composed of a written examination of short-answer questions, technical drawing and production.

Purpose - The labor management department is an important area in charge of the labor-management relations that affects the competitiveness of the company. This study seeks to diagnose labor management education focusing on labor manager competency strengthening curriculum that is currently being conducted domestically and propose an educational model that can contribute to the labor manager competency development by researching improvement measures. Research design, data, and methodology - In this study, the first phase is a Delphi open form survey and 15 expert panels participated. The second phase had 31 expert panels participating and in the final IPA analysis, targeting 111 on-site subjects, it conducted a survey regarding desired level of current educational level and future education requirement. Results - A final 57 subjects regarding 11 items to increase the competency of the labor managers through the first and second Delphi survey was deduced through this study. To add, regarding the current education level and desired level that the current workers are thinking with respect to analysis results of the 57 subjects through the IPA analysis, an educational model could be deduced to increase competency of the labor managers based on the result. Conclusions - Thus far, research regarding labor management has been insufficient as it was defined as a subordinate role to human resources. This study reviews the role and competency of labor managers and presented an educational model to strengthen the capabilities of internal labor managers to re-illuminate the labor manager. However, this study is limited in terms of the diversity of the types of companies participating and the small number of panels. Better data can be produced if such parts are supplemented in the future.

Background: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the tibial nerve within fibrous tunnel on the medial side of the ankle. The most common cause of TTS is idiopathic. This is a retrospective study to define the electrophysiological characteristics of idiopathic TTS. Methods: We reviewed the medical and electrophysiological records of consecutive patients with foot sensory symptoms referred to electromyography laboratory. Inclusion of patients was based on clinical findings suggestive of TTS. Among them, patients with any other possible causes of sensory symptoms on the foot were excluded. Control data were obtained from 19 age-matched people with no sensory symptoms or signs. Routine motor and sensory nerve conduction study (NCS) including medial plantar nerve (MPN) using surface electrodes were performed. Result: Twenty one patients (13 women, 8 men, 9 unilateral, 12 bilateral) were enrolled to have idiopathic TTS (total 31 feet). Tinel's sign was positive in 16 feet (51.6%) of TTS and four feet (10.5%) in control group. The statistically significant electrophysiological parameter was difference of sensory conduction velocity (SCV) between sural nerve and MPN. Amplitude of sensory nerve action potential and SCV of MPN were not different significantly between idiopathic TTS feet and controls. Conclusion: Bilateral development in idiopathic TTS was more common. Tinel's sign and difference of SCV between sural nerve and MPN may be helpful for the diagnosis of idiopathic TTS.

Background: Electrophysiological study has been known as a useful method to evaluate the therapeutic effect of operation in idiopathic carpal tunnel syndrome (CTS). The purpose of this study was to evaluate the clinical and electrophysiological changes after carpal tunnel release (CTR) compared to the preoperative results. Methods: We analyzed the changes of nerve conduction study (NCS) before and after minimal open carpal tunnel release in 18 patients (25 hands) with CTS. Follow-up study was performed over 6 months after operation. Results: Clinical improvement was seen in all cases after CTR. In contrast, electrophysiological improvement was various depending on the parameters; the mean median sensory latency and nerve conduction velocity (NCV) improved significantly (p = 0.001). The mean median motor latency also improved, but NCV and compound muscle action potential (CMAP) amplitude did not change. The extent of improvement was evident in moderate CTS, but not in severe CTS. Conclusions: In this preliminary study, all subjects who underwent CTR achieved a clinical relief along with a significant improvement of electrophysiological parameters such as median sensory latency, sensory NCV and median distal motor latency. After CTR, a number of cases with mild to moderate CTS showed a prominent improvement of clinical and electrophysiological parameters, while fewer improvements were seen in severe CTS, although it did not reach the statistical significance.

Guaranteeing the end-to-end delay deadline is an important issue for quality of service (QoS) of delay sensitive systems, such as real-time system, networked control system (NCS), and cyber-physical system (CPS). Most routing algorithms typically use the mean end-to-end delay as a performance metric and select a routing path that minimizes it to improve average performance. However, minimum mean delay is an insufficient routing metric to reflect the characteristics of the unpredictable wireless channel condition because it only represents average value. In this paper, we proposes a deadline-aware routing algorithm that maximizes the probability of packet arrival within a pre-specified deadline for CPS by considering the delay distribution rather than the mean delay. The proposed routing algorithm constructs the end-to-end delay distribution in a given network topology under the assumption of the single hop delay follows an exponential distribution. The simulation results show that the proposed routing algorithm can enhance QoS and improve networked control performance in CPS by providing a routing path which maximizes the probability of meeting the deadline.

기후변화에 따라 강우 패턴이 변화하며, 집중호우 발생 빈도의 증가가 예상된다. 이로 인해 저수지 상류에서 유실된 토사는 저수지로 유입하여 정수 처리비용 증가, 1차생산성 감소, 어류폐사, 하천경관 악화 등 다양한 문제를 유발한다. 따라서 위와 같은 탁수 피해 저감을 위해 과학적인 모니터링과 예측, 저수지 운영과 관리기술 개발 등의 대응이 요구된다. 본 연구에서는 극한 탁수사상 발생시 대응 기술의 일환으로 저수지 탁수예측 모델의 신뢰도 향상을 위해, 기존 탁수예측 모형인 CE-QUAL-W2(이하 W2)의 탁수 예측 알고리즘을 개선하고 소양강댐 저수지에 적용하여 그 성능을 평가하였다. 최근 W2모델 3.72 버전까지 출시되었으나, 모델은 단순 침강속도만 고려하여 저수지 밀도 특성을 반영하지 못하고, TSS 모의시 독립침강을 가정하여 응집 침강 및 장기탁수 예측에 취약한 한계점을 가지고 있다. 따라서, 과거 연구내용을 바탕으로 수온에 따른 점성계수 변화(Stoke's), 다중 부유 입자별 침강속도 고려 기능을 추가하였으며, 새롭게 점착성유사의 응집 침강을 고려할 수 있는 기능을 추가하여 모델을 개선하였다. 모델에 점착성 유사 모의 전략은 입자 크기 $63{\mu}m$를 기준으로 비점착성유사(NCS)와 점착성유사(CS)로 구분하고, 비점착성유사는 독립침강, 점착성 유사는 응집침강을 가정하였다. 응집 후 중간 입경의 추정은 Gailani et al(1991)의 식을 사용하였으며, 침강속도 계산 공식은 Hwang and Mehta(1989)식을 적용하였다. 수정된 모델은 소양강댐 운영이후 최대 탁수사상이 발생했던 2006년을 대상으로 기존 탁수해석 결과와 수정된 모델의 모의결과를 실측값과 비교 분석 하였다. Stoke's 식 적용시 기존의 모의결과 대비 AME 평균 23%, RMSE 평균 18%가 개선되는 것으로 나타났으며, Hwang and Metha식 적용시에 SS 모의값이 전반적으로 과소평가되는 것으로 나타났다. 또한, 실측 방류 탁수 농도와 모의값을 비교하여 평가 하였으며, 모의기간인 Julian Day 173~365(192일) 동안 모의 결과의 총 TSS 부하량은 실측값의 약 80%수준을 보였으며, TSS 방류 부하기준 Stoke's 식 적용시 기존 모의대비 오차가 1.3% 개선되는 것으로 나타났다.

Recently, the importance of information security has become greater. For this reason, the number of departments related to information security at universities and professional educational institutions is increasing. It is analyzed that the curriculum of such educational institutions has a lot to do with the job competency mentioned in NCS in relation to major subjects. This has the advantage of providing a standardized level of education for each job competency. However from the perspective of students there may be limitations on duplicate curriculum quality of education according to the level of teachers and timely acquisition of necessary elemental skills. In this paper we analyze the curriculum of universities and professional educational institutions and propose a cell-based three-dimensional education model to address the limitations of students. We verified based on the college curriculum that the proposed model can effectively improve its limitations.

The present study aims to demonstrate that it is possible to objectively evaluate the competency (referred to as graduate attributes or program outcomes) of graduates of engineering education programs. To strengthen the link between engineering education accreditation and the qualification/certification system of engineering professionals, referred to as K-Engineering Professional (K-EP), individually assuring the quality of accredited graduates using multiple-choice test as main assessment tool is proposed. Test questions related to the basic vocational skills of NCS are developed for seven of the 10 program outcomes of the ABEEK KEC2015. The three program outcomes, PO1, PO3, and PO5, which need to fully accommodate the characteristics of each disciplinary field, are excluded. A pilot test involving graduates of eight accredited programs is conducted. Applying on Rasch model based on Item Response Theory (IRT), the item difficulty, fit and discrimination of multiple choice test are demonstrated. The pilot study strongly suggests that individual competency evaluation is possible at a certain level for seven program outcomes tested. For PO1, PO3, and PO5, however, questions that address the characteristics of each disciplinary field need to be devised. If a suitable pool of questions is built, it can be used as a program outcomes assessment tool by the accredited programs.

Purpose: The purpose of this study is to clarify the mediating effect of the basic occupational ability in relation to the career barrier and job-seeking efficacy of dental technology students. It aims to provide the basic data for NCS-based education and career guidance. Methods: The subject of the questionnaire survey was dental technology students. The collected data were analyzed using the SPSS 21.0 program. For reliable verification, a significance level of ${\alpha}=.05$ was used and reliability analysis, frequency analysis, descriptive statistics analysis, correlation analysis and regression analysis were performed. Results: The results of the analysis showed that the basic occupational ability had a mediating effect in relation to career barriers and job-seeking efficacy. It was found that the basic occupational ability had a mediating effect in the relationship between job-seeking efficiently and other variables such as difficulty in an interpersonal relationship, lack of self-clarification, conflict with others in important positions, lack of job information, and lack of interest. Conclusion : The results of this study confirmed the importance of the basic occupational ability in improving job-seeking goals, job motivation, job search strength, job skills, and other related areas. If it appears difficult to overcome career barriers such as interpersonal difficulty, lack of self-clarification, conflict with other important people, lack of job information, and lack of interest, then the improvement of the basic occupational ability can be expected to enhance the job-seeking efficiency.
