본 연구의 목적은 국가직무능력표준(NCS) 기반 채용 환경에서 직업기초능력에 대한 취업준비생의 인식 차이를 분석하고, 진로 및 취업교육 설계를 위한 정보를 얻는 것이다. 연구 수행을 위해 전문대, 4년제 대학의 취업준비생 355명을 대상으로 설문조사를 실시하고 직업기초능력의 영역별 중요도와 현재 수준의 차이를 분석하였다. 또 IPA분석을 활용하여 교육 요구도를 확인하였다. 연구결과, 직업기초능력 10개 영역 모두 중요도와 현재 수준 사이의 유의미한 차이를 보였다. IPA분석 결과, 두 집단에서 공통적으로 강화해야 하는 영역은 대인관계능력, 의사소통능력, 수리능력, 문제해결능력, 자기개발능력으로 나타났으며, 현재 과잉상태로 인식되는 영역은 자원관리능력으로 나타났다. 두 집단별 요구도를 확인한 결과, 전문대 취업준비생은 문제해결능력을, 4년제 대학 취업준비생은 의사소통능력, 대인관계능력, 정보능력을 집중적으로 강화해야 하는 것으로 나타났다.

본 고는 5년 간의 고등학교 연합학력평가자료 분석을 통하여 수리영역의 난이도 예측요인을 분석하였다. 난이도 예측을 위한 통계적 모형을 산출하기 위하여 먼저 문항분석을 통해 수리영역의 난이도 예측에 영향을 미칠 것으로 판단되는 주요 변인들을 '내용영역', '행동영역', '문항의 형식' 등의 범주에 따라 추출하였다. 추출된 독립 변인들에 대하여 단계선택방법을 사용한 다중회귀분석을 실시함으로써 정답률 예측에 유의미한 변수들을 선택하였으며, 교차 타당도를 통하여 최종적으로 선택된 예측 모형이 독립적으로 수집된 자료에 대하여 어느 정도의 설명력을 보이는지 검증하였다. 본 연구는 대학수능시험 출제나 현장에서 수리영역의 평가문항을 개발하는데 있어서 사전 정답률을 예측하는데 있어 고려해야 할 요인을 제시함으로써 보다 정확한 정답률 예측에 필요한 기초정보를 제공하는데 그 의의를 두고 있다.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.

Purpose: The purpose of this study was to investigate the changes of static and dynamic balance control ability according to the stability of shoes in elderly woman and female university student. Design: Cross-sectional study. Methods: Six elderly women and seven female university students were recruited for this study. The subject's static and dynamic balance were evaluated while wearing two different types of shoes (comfortable running shoe and masai walking shoe). The BT4 system was used to measure the static (postural sway area and velocity) and dynamic balance (limit of stability on forward, backward and left and right side). The measurement of static and dynamic balance control ability was performed in standing posture wearing comfortable running shoes and masai walking shoes. Results: In the static balance control ability, both female university students and elderly women showed significant increase in postural sway area and velocity when wearing unstable shoes (p<0.05) In addition, in the dynamic balance control ability, both female university students and elderly women showed significant decrease in limit of stability on forward and backward when wearing unstable shoes (p<0.05). Conclusion: In selecting shoes for the elderly, the stability of shoe should be considered for prevention of falls.

Objective: The purpose of this study was to analyze the effects of freezing of gait and visual information on the static postural control ability in patients with Parkinson's Disease (PD) during the bipedal stance with feet together. Method: This study included a total of 36 patients with PD; the freezer group included 17 PD patients (age: $69.3{\pm}6.2yrs$, height: $159.6{\pm}9.0cm$, weight: $63.4{\pm}9.78kg$) and the nonfreezer group included 19 PD patients (age: $71.4{\pm}5.6yrs$, height: $155.8{\pm}7.1cm$, weight: $57.7{\pm}8.6kg$). Static postural control ability was analyzed using variables of center of pressure (COP) and dividing by mediolateral, anteroposterior, and integration factors during a bipedal stance with the eyes open and closed. Results: Freezers and nonfreezers showed increases in anteroposterior velocity, mediolateral velocity, averaged velocity, and mediolateral 95% edge frequency when visual information was blocked. Additionally, freezers had greater anteroposterior range, 95% confidence ellipse area, and COP anteroposterior mean position than nonfreezers. Conclusion: Freezers and nonfreezers showed a reduction in static postural control ability when visual information was blocked. Additionally, the results of this study found a significant difference in static postural control ability between freezers and nonfreezers with PD. In particular, anteroposterior range, 95% confidence ellipse area, and COP anteroposterior mean position might be used to distinguish between freezers and nonfreezers with PD.

Portable low-cost Kinect sensor was used to analyze standing balance ability of the elderly. Eighty subjects who can walk alone and have a normal cognitive level participated in this experiment. Based on Berg Balance scale (BBS) test with 52 points, subjects were divided into Healthy older (HO: 46 persons, BBS: $53.80{\pm}1.19$) and Impaired older (IO: 34 persons, BBS: $49.06{\pm}2.03$) group. Each subject performed 30 seconds four different standing balance tests (EO: Eyes Open, EC: Eyes Close, EOf: Eyes Open on foam, ECf: Eyes Close on foam). Five variables (Mean distance, Range of distance, Root mean square, Mean velocity, 95% ellipse area) were calculated from the hip joint center movement of Kinect sensor. Results showed that there were significant differences between groups for four different standing tests. Calculated variables from kinect sensor showed significant correlation with BBS score. Especially, mediolateral mean distance, mediolateral root mean square, mediolateral range of distance and 95% ellipse area showed discriminative ability for all tests. Mean values of variables of IO were higher than those of HO, which means the decreased balance ability in IO compared with HO. Therefore, it was possible to estimate simple balance assessment of the elderly using portable low-cost Kinect sensor.

Since the turn of the century, scientists have earnestly sought to develop a single laboratory assay or combination of laboratory assays which accurately predict the fertility of a semen sample. Most of these assays have focused on evaluating physical characteristics of sperm such as motility, viability, acrosomal integrity and morphology. In recent years new approches have been used to assess the functional aspects of a sperm that are needed to reach the oocyte, fertilize it and contribute to successful embryo development. Among these techniques are the ability of sperm to undergo a heparin induced acrosome reaction and in vitro fertilization, and the affinity of sperm to bind heparin binding protein. Intensification of research efforts in the area of control of sperm fertilizing ability should be a high priority, in view of undoubted benifits both to our basic understanding of sperm fertilizing ability and to our ability to modify it for Al industry.
