The purpose of this study was to investigate the effects of gender difference in injury experience on biomechanical variables of lower extremity during two leg drop landing. 20 male(injury experience=8, non-injury experience=12) and 20 female(injury experience=11, non-Injury Experience=9) in their 20's were selected as subjects. Two-way mixed ANOVA was performed on the biomechanical variables obtained from the two leg drop landing in a 45cm height box and post-test was performed with bonferroni adjustment(p <.05). The results of this study suggest that the group of female who injury experience could induce the reduction of the peak vertical ground reaction force by increasing the valgus and internal rotation of the knee joint and flexion and internal rotation of the hip joint. In the INE(injury non-experienced) female group, the peak knee flexion angle was the smallest, as well as the flexion of the hip joint and the external rotation angle, and the peak vertical ground reaction force was the highest. On the other hand, the INE female group showed high vertical ground reaction force because they did not utilize the knee and hip joints relatively than the IE(injury experienced) female group, this means that it is relatively exposed to the risk of injury. Therefore, it was found that gender difference in injury experience is a factor affecting factors of knee and hip joint movement and peak vertical GRF(ground reaction force).

The purpose of this study was to investigate the differences in upper and lower strengths and symmetry between upper body injury group, lower body injury group and non-injury group of bowling athletes. The subjects were the upper body injury group (UG), n = 16, the low body injury group (LG), n = 8, the non injury group, [NG], n = 15). The isometric strength of the bowler was measured using Manual Muscle Tester 01165 (Lafayette Instrument Company, USA) and the symmetry index (SI) was calculated. The results were as follow. The symmetry index of hip extension strength and hip external rotation strength was statistically larger in NG than LG (p <.05). The above results suggest that lower body strength and bilateral symmetry was closely related to injuries of the lower body. In order to prevent injury of the bowler, strengthening of lower body strength and symmetrical training are needed.

최근 페이스북 (Facebook), 유투브 (YouTube) 등과 같은 소셜 미디어 서비스가 인기를 얻고 있다. 그러나 기존의 사용자 경험에 대한 이론으로는 사용자간 상호작용에 중점을 둔 소셜 미디어 상의 사용자 경험을 충분히 설명하기에 부족한 면이 있다. 본 연구에서는 경험에 대한 철학적인 고찰을 통해 기존 사용자 경험 개념을 보완하는 개념인 공동경험을 재정의하였다. 촉지적 상호작용을 통해 사용자들간에 향상된 품질의 상호작용이 가능해져, 사용자들의 공동경험 지각이 증가한다는 가설을 검증하기 위해 실험 목적의 소셜 미디어 시스템을 구축하고 그 시스템 상에서 실험을 진행하였다. 실험 결과에 대한 분석과 연구의 의의가 제시되어 있다.

This study defined the types of barrier and conducted the impact of barrier in adventurous sports. There are many research on adventurous sports, but these researches have several limitations. First, these studies have overlooked important role of barrier in adventurous sports. Also, previous studies on barriers haven't showed the moderating effects of personality on barriers. So, this study attempts to complement the lack of existing research and this purposes of the study is as follows. First, it is to show the positive impacts of barriers on absorbing experience that had been overlooked in the previous researches. Second, it is to propose the moderating effects of personality-arousal seeking, reactance tendency- on the relationship between barriers and absorbing experience. Survey research is employed to test these hypotheses. Previous researches, such as marketing, adventure sports, hedonic research, have been referenced to measure constructs. We collected data involving various adventure sports, and used 171 respondents to analyze these data using moderating regression. In the final section, we discussed several limitations of our study and suggested directions for future research. We concluded with a discussion of managerial implications, including the potential to advance understanding adventure sports and implying an enhanced ability to satisfy target consumers of it.

이 논문은 나대지에서 획득한 polarimetric SAR 자료의 후방 산란 계수(backscattering coefficient) 분석을 위한 surface parameters 추출 및 forward mapping에 대하여 서술하였다. Surface parameter는 토양의 거칠기(ks), 수분 함량(m/sub v/), 유전 상수(ε/sub m/) 등이 포함되어 있고, 유전 상수의 추정을 위하여 0.3-1.3GHz 구간의 자료를 기반으로 제안된 N. R. Peplinski의 경험상의 모델(Empirical Model) 알고리즘을 사용하였다. 추정된 surface parameter는 polarimetric SAR 자료의 산란 현상을 특징짓기 위한 forward mapping의 입력 값으로 이용되었으며, scattering model로 Oh의 경험상의 모델을 사용하였다. 각각의 surface parameter ks, θ, m/sub v/는 Oh 모델을 이용한 시뮬레이션을 통하여 레이더 후방 산란 계수에 미치는 영향에 대하여 조사되었다.

This paper aims to grasp the characteristics of the cognition and preference on the continents, their relationship, and then each nation's location and direction in case of Korean high school students. First, there exists difference of cognition by six continents as well as by gender and experience of foreign visit among the students. The students have somewhat different preference by each continent, which was affected by gender and experience of foreign visit as well. Second, the cognition of the students on each nation's location showed a positive relation with that on the continents, which was decided by adjacent distance with Korea. The empirical results showed that the higher the gaps of latitude over longitude are, the lower the cognition of the students on direction among nations are. Moreover there are significant gaps by gender and experience of foreign visit in orientation ability. As a result, the geography education may have to be develop the high school students' balanced cognition ability in relation to continents and nations.

The aim of this study was to analyze the relationship between salivary flow, salivary buffer capacity, level of mutans streptococci and dental caries experience in Korean dental college students. A total of 81 students of the school of dentistry, Chonbuk national university, mean age of 26.1 years, were subjected to oral examination to establish the DMFT and DMFS according to WHO guidelines. Saliva samples from the students were collected for quantitating stimulated and unstimulated salivary flow rate. Buffering capacity was estimated using a commercial colorimetric strip test, and number of mutans streptococci was determined from stimulated saliva using a strip mutans test. The means of DMFT and DMFS were 6.57 and 12.65, respectively. The stimulated salivary flow rate was correlated with DMFT(${\acute{o}}\;=\;-0.219$) and high levels of salivary mutans streptococci were significantly correlated with higher DMFT and DMFS scores(P<0.05). Level of mutans streptococci was significantly correlated with dental caries experience, in both DMFT and DMFS score, and buffering capacity was inversely correlated to DMFT score. However, unstimulated salivary flow rate was not correlated with caries experience.

1970년대 이래로 노인들의 평균적인 경제상태가 향상되어 왔지만, 상당한 수의 노인들이 여전히 빈곤할 뿐만 아니라 노인들 각자가 경험하는 경제복지는 다르다. 본 연구는 노인들이 경험하는 경제복지를 조사하고 이를 바탕으로 상이한 노인가계들간의 복지상태를 비교하였다. 경제복지는 주거비가 차지하는 가계소득에 대한 비로 측정하였다. 노인가계는 노부부가계, 노인남성가계, 노인여성가계로 구분하였다. 미국의 3,449 노인가계들이 연구분석에 사용되었다. 노인가계들간의 경제복지를 비교하기 위해 다중회귀분석이 사용되어졌다. 분석결과에 의하면 상이한 노인가계들간에 경제복지는 상당한 차이가 있었다. 특히 노인여성인 경우 경제복지가 가장 낮은 것으로 나타났다.

본 연구는 마케팅의 네 가지 경험적 접근방법, 즉 정보탐색적 접근, 브랜드 컨셉으로서의 경험, 즐거움의 경험, 총체적 경험 등의 내용을 살펴보고 이들의 기여와 문제점 및 한계를 살펴보았다. 또한, 감성적 경험과 소비 시점의 경험에 관해서도 논의하였다. 경험적 접근방법은 새로운 마케팅 수단으로 충분한 잠재력을 가지고 있으며 인지적 접근, 브랜드의 기능적 혜택을 강조하는 기존 마케팅 방식과는 상당한 차이가 있다. 하지만, 경험적 접근방법 앞으로 해결해야 할 많은 과제가 남아 있으며, 일부 실무적인 서적들이 주장한 바 와 같이 인지적, 기능적 마케팅 방식을 대체하는 것은 아니라고 할 수 있다. 기존 전통적인 마케팅 방식에 대하여 보완적 역할을 수행할 수 있으며, 제한적인 조건에서만 적합한 방식으로 평가할 수 있다.
