고령화가 다른 국가에 비해 상대적으로 빠르게 진행되고 있는 상황에 대비한 고령운전자의 연구가 부족한 실정이다. 본 연구는 고령운전자의 교통사고 원인을 신체적 능력저하보다도 심리적 요인의 변화에 입각하여 고찰해 보려고 한다. - 고령운전자의 교통사고 고령운전자의 교통사고에서 가장 두드러지게 나타나는 행동적 특징은 좌회전시 발생하는 교통사고가 많다는 것이다. 그리고 사고장소에 따른 분석결과에 의하면, 교차로에서 발생하는 사고가 많다는 것이 확인되었다. - 고령운전자의 조심성과 보상행동 고령운전자의 조심성이 운전행동에 미치는 알아보기 위하여 운전자의 운전확신수준을 비교해 보았다 운전확신수준은 4개 요인으로 구분되었고, 고령운전자와 젊은 운전자의 운전확신수준 차이를 검증한 결과를 보면, 고령운전자의 운전확신수준이 젊은 운전자에 비해 현저하게 떨어지는 것을 알 수 있었다 그리고 좌회전을 선택시 소요되는 시간을 분석하여 고령운전자의 조심성을 이해하려고 하였다 고령운전자는 젊은 운전자에 비해 선택소요시간이 현저하게 길어진다는 사실을 발견하였다. - 고령운전자의 운전일탈행동 연령에 따른 운전일탈행동의 변화를 보면, 연령이 증가함에 따라 운전일탈행동의 위반, 오류, 착오의 평균 점수는 감소하는데, 각 요인이 감소하는 정도는 차이가 있었다. 위반점수는 연령의 증가에 따라 급격하게 감소하는 모습을 보이는데 비해 오류와 착오점수는 연령의 증가에 따라 완만하게 감소하는 경향을 보였다.

This study discusses the traditional main life culture of Korea and the relations with the traditional manners of Korean culture. According to studies of literature and an analysis, it shows the traditional courtesy can be linked to the housing structure of the Cho-sun dynasty which can be termed as a representation of traditional Korean society. Housing culture of Cho-sun dynasty led to a most characteristic living culture. To be specific sit-down culture use norms, hierarchy and fittings can be sited. The sit-down culture in turn led to the main courtesies of greeting, table manners, etiquette for entrance and exit, the carefulness shown to elders, the self-restraint of speech and action and the manners between men and women, But in today's world there are realistic difficulties that make the application of these norms in everyday life difficult. But at the same time we must realize that there are traditional norms which overcome time and which affect today's norms.

In the system of underground transmission line, the rate of electrical failure is very low, but, if once occuring, the failure evolves into a paralysis of the system, the time of restoration is very long, the damage from stopping of power supply is very serious, and the cost of restoration is very great. Because of these problems, you must try to protect the system and equipment from every electrical failure by contributing much carefulness to the design and operation of the underground system. This study summerizes the results of simmulation tests about the effect of installing this protection device on the insulated joint box and the terminal end box.

본 연구는 운전자의 조심성에 초점을 두고 고령운전자와 청소년운전자의 운전확신수준과 운전행동과의 관계를 알아보았다. 우선, 운전확신수준을 측정하기 위한 도구를 제작하여 사용하였으며, 조사대상자들의 운전경력, 주행거리, 위반경험, 사고경험을 함께 조사하였다. 조사대상자는 만 25세 이하 청소년운전자와 만 65세 이상 고령운전자 325명이었으며, 고령운전자의 자료는 1:1 인터뷰를 통하여 수집하였다. 먼저, 운전확신수준의 구조를 알아보고자 요인분석을 실시하고, 고령운전자와 청소년운전자의 운전확신수준을 비교하였다. 그리고 고령운전자와 청소년운전자의 운전확신수준과 운전행동과의 관계를 알아보았다. 운전확신수준은 '운전상황', '안전운전', '운전능력', '주의'의 네 요인으로 이루어져 있었으며, 고령운전자의 운전확신수준은 청소년운전자의 운전확신수준보다 낮은 것으로 나타났다. 고령운전자 집단에서는 운전확신수준과 운전경력, 위반경험이 강한 상관관계를 가지고 있었고, 청소년운전자의 운전확신수준은 운전경력, 주행거리, 위반경험, 사고경험과 강한 상관관계를 가지고 있는 것으로 나타났다.

The purpose of this research was to consequences of the sale effect derived from similar type of personality between the customer and the apparel salesperson. For the purpose of the verifications, random survey is made to 225 people over 20 years in age among the residence in the district of Seoul and using SPSS program, the reliability, frequency and crosstabs. The results of this study as follows: 1) In the fashion apparels of higher level of involvement, lower assertiveness but carefulness and analytic attitude of the salesperson is preferred rather than the customer's personality. 2) Difference are shown of the consequence of the sale effect by the corresponding type of the personality, depending on the degree of the involvement. 3) As for the level of the influence of the sale effect by the concordance of personality type depending on profession, student group are more conscious rather than the professional group in the aspect of concordance of personality type with salesperson.

With the progress of the aging society into the aged society, the planning of senior housing is inevitably required. Among the factors of planning, color appeals to people's vision which mostly accepts information about the environment, so age-related color vision changes should be studied. The purpose of the study is to find out characteristics of color perception focused on yellow and blue with advancing of the yellowed eye sight in the old age. The findings are as follows. (1) Regardless of gender, losses of color perception in sensitivity is occurred as aging is proceeded. But the rate of reduction is mitigated compared with the ex-research in Japan because of the promotion of physical health. (2) Human lens coloration was not common until 85 years old and the hue of yellow and red was easily perceived by the older subjects. (3) Yellow is more preferred to other colors by the elderly and accuracy of yellow-color perception is higher than that of blue-color. (4) It is especially hard for the elderly to perceive the difference between pure blue and mixture of blue-green. Therefore blue and blue-green should not be adopted simultaneously in senior housing environment. Except for the space which specially requires carefulness, various color preferred by the elderly should be applied to the senior housing environment to satisfy their psychological condition and provide the vitality of life.

Excavation works of cylindrical shafts and tunnels for the construction of a variety of infrastructures have been frequently going on in the urban areas. When ground excavations of cylindrical shafts and shallow tunnels proceed in the ground condition of high water level and silt particle component, ground water drawdown involving soil particle migration causes loosening of ground around tunnels and shafts, causes settlement and deformation of ground. Damages due to ground sinking and differential settlement can occur in the adjacent ground and structures. The extent and possibility of damage relevant to ground water drawdown and soil particle migration can't be so precisely expected in advance that we will face terrible damages in case of minor carefulness. This paper introduces two examples of construction management where using incremental deformation graph of inclinometer, we noticed the possibility of soil migration due to ground water drawdown in the excavation process of vertical shaft and shallow tunnel, analysed a series of measurement data in coupled connection, properly prepared countermeasures, so came into safe and successful completion of excavation work without terrible damages. The effort of this article aims to improve and develop the technique of design and construction in the coming projects having similar ground condition and supporting method.

This study was to investigate the types of errors and the frequency of errors to understand students' solving process on the descriptive items with the students of an excellent high school which located in a non-leveling local school district of Gyunggi Province. All 11 items were developed in the equation of a circle and 120 students who attended this high school participated in solving them. The result showed a tendency as follows: Logically invalid inference(Type A, 38.83%) of errors, Omission error of the problem solving process(Type B, 25%), Technical error(Type C, 15.67%), Wrong conclusion(Type D, 11.94%), Use of wrong theorem(Type E, 5.97%), and Use of wrong picture(Type F, 2.61%). The logically invalid inference the students showed with a largest tendency was made because of the lack of reflection. This meant that this error could be corrected in a little treatment of carefulness.

Over the past decade, mass spectrometry-based metabolomics, especially two dimensional gas chromatography mass spectrometry (GCxGC/TOF-MS), has become a key analytical tool for metabolomics data because of its sensitivity and ability to analyze complex biological or biochemical sample. However, the need to reduce variations within/between experiments has been reported and methodological developments to overcome such problem has long been a critical issue. Along with methodological developments, developing reasonable performance measure has also been studied. Following four numerical measures have been typically used for comparison: sensitivity, specificity, receiver operating characteristic (ROC) curves, and positive predictive value (PPV). However, more recently, such measures are replaced with F1 score in many fields including metabolomics area without any carefulness of its validity. Thus, we want to investigate the validity of F1 score on two examples, with the goal of raising the awareness in choosing appropriate performance comparison measure. We noticed that F1 score itself, as a performance measure, was not good enough. Accordingly, we suggest that F1 score be supplemented with other performance measure such as specificity to improve its validity.
