본 어플은 사회적 문제를 기술적 패러다임에 맞춰 해결하고자 기획되었다. 일반적으로 자기 자신의 문제점보다 다른 사람의 문제점이 더 쉽게 보이고 인식하게 된다. 작은 문제로 볼 수 있지만 최근 사회적 문제로 발생하고 있는 "따돌림" 문제는 인간의 존엄성마저 잃어버리게 하고 있다. 친구들의 문제뿐 아니라 부모와 자식, 형제, 자매 등 가족들과의 의사 단절 등으로 확대되고 있으며, 이런 문제를 해결하기위하여 많은 노력들을 하고 있지만, 실제 치료의 시간도 오래 걸리고 많은 금전도 필요하게 된다. 이렇기에 최근 트랜드의 축이 되고 있는 "스마트폰"을 활용하여 시간적, 공간적 제약을 최소화하고 더불어 수익성을 고려하여 "WHO"의 어플을 기획하게 되었다. 특히, 사후문제 처리가 아닌 "예방"의 목적으로 상대방의 문제점을 파악하는 것과 자신의 문제점을 인지하고 해결하는데 중점을 두었다. 내가 아닌 지인이 나에 대한 평가를 보다 객관적인 평가를 하기 위하여 대상자를 자신의 스마트폰 주소록에 한정하였으며, 악위적인 댓글 등을 최소화하기 위하여 금지어, 입력글자 개수제한 등을 추가하였다. 평점을 줄 수 있게 하여 상대적이고 객관적인 점수로 자신의 평점을 알 수 있게 하였고 보다 빠른 인지를 위하여 별모양의 그래픽을 사용하여 평가하도록 하였다. 특히, 본 어플은 설치자만이 사용할 수 있기 때문에 주소록에 있는 명단에서 "초대하기"기능으로 설치를 유도하였다. 본 어플을 개발 후 2주간의 테스트를 통하여 어플의 기대효과에 대한 가능성에 대해 확인할 수 있었으며 추가로 개발될 어플에는 분야별 항목을 추가하여 보다 섬세한 자아평가를 가능하도록 기획하고 있다.

To ensure safer road conditions, understanding the human factors influencing driving behavior is crucial. However, there are many difficulties in deriving the characteristics of individual human factors that affect actual driving behaviors. Therefore, this study analyzes self-reported dangerous-driving propensities in order to explore potential correlations with drivers' behaviors. The goal is to propose a method for assessing driving tendencies based on varying traffic scenarios. The study employed a questionnaire to gauge participants' propensity to drive dangerously, utilizing a simulator to analyze their driving behaviors. The aim is to determine any notable connections between dangerous-driving propensity and specific driving behaviors. Results indicate that individuals exhibiting a high propensity for reckless driving, as identified by the Korean DBQ, tend to drive at higher speeds and display more aggressive acceleration patterns. These findings contribute to a potential method for assessing reckless driving drivers.

This study attempted to look into the effects of the job environment and job esteem on job satisfaction in the field of skin beauticians. To achieve this, a survey of their characteristics, job environment, job esteem and job satisfaction was carried out on 470 women in their 20s~50s working at skin care shops in the Seoul and Gyeonggi areas. First, it was found that the effects of the working environment on their vocational satisfaction, sense of belonging, level of contribution, wages and welfare, which are sub-factors of job satisfaction, are relatively high. This result shows that it is important to ensure proper resting facilities and resting areas. Second, it was shown that the higher the social evaluation, self-(implicit) assessment, future value, and self-fulfillment orientation, the higher the sub-factors of job satisfaction. This means that it is important to treat skin beauticians as professionals in order to improve their social recognition. The sub-factors of job environment-working conditions, organizational environment and job stability, and sub-factors of job environment-social evaluation, self(intrinsic) evaluation, future value and self-achievement orientation, had a major effect on the sub-factors of job satisfaction, respectively. Together with the general improvement in the sub-factors of job environment, the future value, as well as social evaluation, self(intrinsic) evaluation and self-achievement orientation, which together constituted the current value of job esteem, were the major factors affecting job satisfaction. Consequently, this study hopes to contribute to the development of the skin beauty industry by providing basic data on personnel management for skin care managers to improve skin beauticians' job satisfaction.

카툰 렌더링 그래픽을 기반으로 한 온라인 RPG 게임인 마비노기에서는 게임이용자들이 염색 시스템을 통하여 의복아이템에 자신들이 원하는 색을 자유롭게 표현할 수 있다. 마비노기에서 색에 관련된 주목할 만한 현상은유행색이 존재하고 색에 따라 같은 아이템의 가격이 달라진다는 점이다. 유행색이 존재하는 것은 현실과 비슷하지만 같은 아이템이 색에 따라 가격이 달라지는 것은 현실에서는 보기 드물다. 이는 현실과 비슷하면서도 심리적인 속성이 다른 사이버공간만의 특징이라고 생각해 볼 수 있다. 따라서 마비노기에서 게임이용자들이 색을 선택하고 사용할 때 작용하는 심리기제가 존재할 것이라고 가정해 볼 수 있다. 이에 본 연구에서는 마비노기에서 색 선택 행동의 심리적 유형을 확인하고 유형별 특징을 알아보기 위해 자아존중감을 측정하였다. 예비 조사를 통해 게임이용자 20명과 온라인 인터뷰를 실시하여 색 사용 경험을 추출하고, 추출한 경험을 바탕으로 18문항의 색 선택 행동 문항을 구성하였다. 본 조사에서는 온라인 설문으로 129명의 게임이용자를 대상으로 색 선택 행동과 자아존중감을 측정하였다. 연구 결과 색 선택 행동은 4개의 요인-색채 둔감성, 유행추종, 개성표현, 캐릭터이미지와의 적합성-으로 구분되었다. 색선택 행동 4개의 하위 요인을 기준으로 군집분석한 결과 색 선택 행동 유형은 각각 색 분화형, 유행추종형, 색 둔감형으로 구분되었다. 색 선택 행동 유형과 자아존중감과의 관계에서는 자아존중감 하위 범주 중 부정적인 자기평가, 타인의 의견에 대한 걱정, 의존성의 세 가지 하위 범주에서 색 선택 행동 유형에 따른 차이가 유의미하게 나타났다. 한편 자의식 차원에서는 색 선택 행동 유형간 유의미한 차이가 발견되지 않았다. 유행추종형은 다른 두 유형에 비해 상대적으로 자아존중감 수준이 낮음을 확인할 수 있었다. 반대로 색 둔감형은 다른 두 유형에 비해 상대적으로 자아 존중감 수준이 높았다. 색 분화형은 유행추종형과 색 둔감형의 중간 수준의 자아존중감을 볼 수 있었다. 유행추종형은 자기의 외부에서, 색 둔감형은 자기의 내부에서 색과 관련된 자신에 대한 가치감의 소재와 근원을 찾는 특성이 있다고 해석할 수 있다. 본 연구는 온라인 RPG 게임에서 게임이용자들의 색 선택의 심리적 기제를 확인하고 색 선택 유형별로 자아존중감과의 관계를 확인함으로써 색 선택 행동의 심리적 기제를 밝히려는 기초연구라는 점에 의의가 있다. 추후에는 게임이용자들의 색 선택 행동을 보다 포괄적으로 이해하기 위해 게임이용자들이 가지고 있는 공통적인 색이미지와 개별적인 색이미지 및 색이미지의 심리적 구조를 알아보기 위한 색채감성연구가 필요할 것이다. 이러한 연구들은 게임을 제작할 때 캐릭터 디자인과 아이템 디자인에 어떠한 색을 사용해야 되는지 방향을 설정하는데 도움을 줄 수 있을 것이다.

This study aimed to specify Vessel Traffic System(VTS) operators' situational awareness(SA) tasks and examine differences in subjective ratings for three levels of SA. Data for relative frequencies of SA tasks were collected by using direct in field observation. Subjective rating scores were obtained using a questionnaire method and compared in terms of VTS operator's gender and length of service career. The results are as follows. First, it was found that the VTS operators perform information perception task elements more frequently than those for information integration and prediction. Second, VTS operators tended to show subjectively lower evaluation scores for prediction than information perception or integration. Third, male VTS operators rated their SA ability higher than females. Fourth, the male VTS operators more than 15 years of career service showed higher subjective rating scores than those with under 5 years of service. Female VTS operators with different levels of career service showed a similar level of subjective rating scores. These results suggest that the frequency of SA related tasks and subjective SA evaluation can differ in terms of SA levels and individual differences.

The purpose of this study is to analyze the importance and performance of core competencies recognized by Korean sports students and to identify directions and methods for strengthening the competence of sports students in the future direction of future society. The results of analysis of 309 students of sports major students are as follows. First, the importance of core competencies recognized by college students in sports was in the order of self - management capacity, interpersonal capacity, communication capacity, comprehensive thinking ability, resource information technology utilization capability, and global capability. Second, the students' performance of their core competencies evaluated by sports college students was in the order of interpersonal competence, self-management competence, communication competence, comprehensive thinking ability, global competency, and resource information technology utilization competency. Third, the difference between the importance of core competence and the degree of performance was found to be significant in all areas, and the areas of great difference were total thinking, communication ability, resource information technology utilization capacity, self-management capability, Relationship competence. While college students in sports college have relatively high level of interpersonal competence, self-management competence and communication ability, comprehensive thinking ability, resource information technology utilization capacity and global competency are weak. Therefore, It will be able to be reborn as the talent required by society. Therefore, universities need to cultivate competitive sports talent through innovation of curriculum and capacity of faculty, and it should be recognized that this can be linked to the competitiveness of universities.

Purpose : Renal blood oxygen level-dependent (BOLD) MRI has been used in the evaluation of renal oxygenation. We tried to provide the normal $R2^*$ value of the human kidney with 3.0 T, and evaluated the differences in $R2^*$ values according to gender and location. Materials and Methods: Twenty-four healthy volunteers underwent BOLD MRI at 3.0 T. Multi gradient echo-echo planar imaging sequence with seventeen echoes was used. After generation of the $T2^*$ map, the $R2^*$ was calculated. The statistical differences in $R2^*$ values between the cortex and medulla, males and females, and the right and left kidney were analyzed. The regional differences of $R2^*$ within the both kidneys were evaluated respectively. Results: BOLD MRI was successful in all participants. No gross artifact interfered with $R2^*$ measurement. The mean $R2^*$ at 3.0 T was $17.1{\pm}2.60s^{-1}$ in the cortex and $27.7{\pm}4.83s^{-1}$ in the medulla (p < 0.001). The $R2^*$ value in the medulla was significantly higher in the male than female volunteers (p = 0.025). There were no statistical differences of $R2^*$ according to the side and location in the kidney (p = 0.197). Conclusion: Renal BOLD MRI can be efficiently performed with 3.0 T MRI. Renal medullary hypoxia is present in normal volunteers. Our results may be used as reference values in the evaluation of pathologic conditions using BOLD MRI.

A nondestructive test method based on the self-compensating frequency response function is proposed in this paper to quantitatively measure the attenuation in concrete materials. Since the proposed technique measures inherent attenuation of material itself, more stable experimental results can be expected. In advance, comparison of the experimental results to those obtained by other methods shows the repeatability and accuracy of the proposed technique.
