Depending on the launch of the emotional generation, many researches developing the automobile preference color which reflects the preference color of the consumers are advanced. This study investigate preferred colors and emotional image of the car color reflecting the product design and consuming psychology. According to surveyed ages and gender, there are eight categories (women/20 's, 30 "s, 40 's, and 50 's and men/20 's, 30 "s, 40 's, and 50 's) based on the 30 persons. Preferred color is black, white, sky blue, purple, pink, and orange order. If black, white and gray are excluded, remained in the order of blue, yellow, and purple. There are big deferences on preference color when emotional preference color of cars is showed or not. Practically, the preference color is following in sensitivity. However the car image is recognized actually with conservativeness, they hesitates selection of the bright chromatic color car.

This study comprised 157 extracted teeth, 73 of the teeth originated from mates and 84 from females, the age range was 12-79 years. The correlation coefficient of each Gustafson's criteria in relation to age was carried out. Age estimation were performed on 157 teeth according to the method by Gustafson and by use of multiple regression, as used by Johanson, after evaluating the six criteria of Gustafson by multiple regression computer analysis. Two prediction formulas and standard deviations were compared with each other. The results were as follows : 1. The author found that six Gustafson's criteria had strong correlation with age except root resorption, and correlation coefficients were r = 0.79 (Transparent dentin), r=0.72 (Secondary dentin), r 0.69 (Periodontal change), r=0.63(Attrition), r = 0.39 (Root resorption), respecti vely. 2. The age estimation formula by Gustafson's method was calculated as follows: Y 8.88 + 3.52X r =0.87, r2 = 0.76, SD = 8.18, F = 483.56, P < 0.01 The age estimation formula by multiple regression was calculated as follows: Y 8.57 + 6.37T + 6.37T + 4.63P + 2.70S + 2.40C + 3.08A + 1.34R r= 0.89, r2 = 0.78, SD = 7.82, F = 91.62, P < 0.01, Durbin-Watson Coefficient = 1.09 3. In comparison of two estimation formulas, the formula by multiple regression, the method of Johanson, was found to be slightly more reliable than Gustafson's method. Gustafson's method SD = 8.18, Multiple regression (Johanson's method) SD = 7.82 4. It was reaffirmed that Gustafson's six criteria could be a independent variable in multiple regression analysis.

본 연구의 목적은 알코올 문제의 현황을 파악하고 효과적인 음주교육 방안을 모색하기 위한 것이다. 사회문화적 행위로서의 음주행동의 특징을 파악하고 음주로 인한 위해가 우리에게 미치는 영향을 파악하기 위한 것이다. 음주행동은 한 사람이 속한 사회의 문화와 관습이 허용하는 범위에 따라 그 사회가 공유하는 음주에 대한 태도나 가치의 영향을 받아 학습을 통해 습득하게 된다. 음주는 사망률, 이환율, 유산율, 범죄율 등에 막대한 영향을 끼치고 있으며 이로 인한 사회적 비용과 생명손실은 엄청난 것이다. 매스미디어를 통한 음주교육은 다른법적 제재와 병행될 때 효과적이다. 음주연령이나 세금부과 등을 통해 음주행위를 통제하는 것이 가능하다. 음주교육의 주기능은 법령과 처벌에 대한 두려움(perceived fear)를 높이는 것이다. 음주행위에 관용적인 사회 분위기를 변화시키는 것이 법령이나 처벌보다 더 효과적이다. 과도한 음주행위에 대한 비판적인 사회적 분위기와 같은 비공식적인 사회적인 제재가 음주문제의 예방에 더욱 중요하다. 청소년의 음주행위는 부모와 동료집단과의 관계에 의해 크게 영향을 받기 때문에 부모와 동료집단의 참여하에 객관적인 태도를 통해 자율적인 결정을 할 수 있도록 유도해야 한다. 음주교육에 대해 지식과 경험을 갖춘 교사가 교육을 실시하여야 하며 소그룹 활동을 통해 음주문제에 대한 이해와 바람직한 태도를 습득하게 하고 동료집단의 압력을 거부할 수 있는 능력을 키우는 것이 필요하다. 교사는 편견이 없는 객관적인 태도를 갖추어야 하고 최종적 결정은 지식에 근거하여 청소년이 하도록 하여야 한다. 음주는 가정불화, 좌절감, 실업, 이혼 둥의 부정적 감정과 연관되어 있으며 깊은 인간관계를 통한 상담이 효과적이다. 단주친목과 같은 자발적인 민간단체는 알코올 문제를 가진 사람들이 서로 모여 친목하는 가운데 도움과 치료를 받을 수 있다는 점에서 매우 효과적이다. 이러한 단체의 활용이 더욱 확대되어야 한다. 병원에서의 음주교육은 노조의 참여하에 전문적인 의료인들에 의해 이루어져야 한다. 이전에 알코올중독에서 회복된 사람을 동료교육가(peer educator)로 활용하는 것도 효율적인 교육방법중의 하나이다. 의과대학의 교과과정에 음주교육에 대한 내용을 더욱 확대하여야 한다. 음주교육은 음주라는 행위의 저변에 깔린 문화적 심리적 요인에 대한 깊은 이해를 토대로 계획되고 실시되어야 한다. 음주교육은 지역사회 전체의 참여를 통해 부모, 학생, 정부, 민간단체, 매스미디어의 공동참여를 통한 다각적인 접근이 요구된다.

This study explores the causes of online helping behavior. This study tests the effects of various explanatory factors on the basis of previous studies on helping behavior. These factors include social demographic, situational, motivational, and social capital factors. According to the survey of 475 university students living in Seoul in 2010, age and religion have significant effects on online helping behavior. In addition, the perceived helping opportunity, time and effort cost to help, and social capital factor have significant effects on online helping behavior. Results reveal that the effect of social capital factor is the largest among other variables. However, it is shown that the effects of benefit from helping, empathy, and personal norm are not statistically significant. It is also revealed that the effect of social capital factor is important across all types of online helping behavior except information helping. The policy implications are discussed.

This study was undertaken to obtain the data for age determination following the calcification degree of the second molar, third molar in the point of forensic odontology. The intraoral panoramic radiograph of 1600 male and 1600 female (100 persons each age) ranging from 7 to 2 years of age were studied. The developmental state of the second molar and third molar were divided into 12 stages following the calcification degree and correlations of second molar developmental stage and statistically analyzed. The results were as follows : 1. There was remarkable correlation between the development of the second molar, the third molar and age. 2. There was no significant developmental differences between the right and left second molar, third molar.(p>0.05) 3. The developmental stages of the lower second molar was more advanced than those of upper second molar. (p<0.05) 4. The developmental stages of upper third molar was more advanced than those of lower third molar. (p<0.05) 5. Both the developmental stages of second, third molars were earlier in the female than in the male. (p<0.001) 6. For the purpose of age estimation according to developmental stages of the second, third molar, linear equations are as follows. (p<0.001) second molar : male upper : Y=1.3927X + 0.2213 (r=0.72) lower : Y=1.4132X + 0.0012 (r=0.78) female upper : Y=1.4914X + 0.2151 (r=0.73) lower : Y=1.5429X - 0.0911 (r=0.78)

The layout in picture book is a visual statement that arouses children's psychological reaction upon pictorial positions and those disposition, and that indicates a correlation between theme and background and characters' movements. This study firstly confirmed that children's perception and experience are variously formed according to age, past experience, psychological action, physiological impulse, mentality, growth environment, etc., in order to analyze how the pictorial layout in children's picture book has influence on children visually and psychologically. Likewise, visual and psychological perception was carried out targeting on the children between 4 and 7 years old, based on the perceptive specific and process that have been studied by previous researchers. In addition, the children's picture books published overseas or domestically were presented as the related cases, in order that the facts analyzed may be drawn to harmonious and effective pictorial layout. Lastly, it is expected that the conclusion suggested by this study may be of help to illustrators to design picture books individually and creatively, as well as be applied to studying effective expression in the educant who learn about illustration.

치아는 성별과 연령의 추정은 물론 혈형 검사와 유전자 검사까지 가능하게 하는 중요한 법의치과학적 자료이다 대부분 치아를 이용한 연구는 핵 DNA가 들어있는 치수에서의 연구로 치수내에는 풍부한 혈액 및 세포가 분포해 있어 핵 DNA가 다량 함유되어 있다. 그러나 순수 상아질에는 핵이 없고 따라서 핵 DNA도 없는 것으로 알려졌지만 치수내에 존재하는 핵 DNA가 상아세관을 통하여 상아질내로 침투할 가능성이 있고 실제 근관치료가 되어 있는 무수치를 감정하게 되는 경우도 있다. 본 연구에서는 이러한 치아중에서도 근관치료를 받은 무수치에서 개인식별에 활용되는 유전자가 검출되는지 여부를 확인하고자 하였다. 40개의 근관치료된 치아상아질에서 DNA출 추출하고 중합효소반응을 이용하여 증폭절편다형(Amp-FLPs)을 실시하고 X-Y homologous amelogenin gene과 STR 유전좌위 F13A01, LPL를 검색하여 다음과 같은 결과를 얻었다. 1. 40개의 근관치료된 치아중 19개에서 DNA가 추출되었다. 2. X-Y homologous amelogenin gene 검색으로 40개의 근관치료된 치아에서 21의 남자 치아중 5개, 19개의 여자치아중 7개 등 모두 12개 치아에서 성별검사가 가능하였다. 3. F13A01 유전자는 43개의 근관치료된 치아중 6개의 치아에서 검색되었으며, 4개의 대립유전자 및 5개의 유전자형을 관찰하였다. 4. LPL_유전자는 40개의 근관치료된 치아중 7개의 치아에서 검색되었으며, 3개의 대립유전자 및 3개의 유건자형을 관찰하였다. 이상의 결과를 종합하여 볼 때 근관치료된 치아상아질에서 중합효소반응을 이용한 성별검사 및 STR 유전자위의 검색은 일부 치아에서만 가능하였으나, 근관치료된 치아들도 개인식별을 위한 법의치과학적 자료로서 유용할 것으로 사료된다.

Age determination in children have been criticized because they rely on subjective estimations of tooth development, as seen in radiographs. This study was undertaken to obtain the objective estimation of developing teeth. The panoramic radiograph of 254 males and 254 females ranging from 6 to 14 years of age were studied. The structures measured were crown height, apex width and root length. The data weree statistically investigated with SPSS/PC + package. The results were as follows : 1. With the aid of a multiple regression model, a linear relationship between some of these distances and age was shown. 2. In th total material(6-14yr) and four-yr. intervals, linear equations are as follow : Boys : 6-14 age = 683 + 145.6 44RL + 126.6.45RL + 71.1 46DRL - 161.3 46DAW 6-10 age = 1202 + 72.6 46DRL + 100.2 44RL + 75.1 45RL 8-12 age = 3818 + 75.9 45RL - 190.9 44AW 10-14 age = 4151 + 58.6 45RL - 84.0 45AW - 130.6 44AW Girls : 6-14 age = 1587 + 104.9 45RL + 113.4 44RL - 233.1 46DAW + 81.4 47DRL - 255.9 46MAW 6-10 age = 1821 + 55.8 46DRL + 67.2 45RL - 184.2 46MAW + 56.3 44RL 8-12 age = 2435 + 68.2 45RLL + 71.3 44RL 10-14 age = 3485 + 49.9 47DRL - 51.3 45AW - 179.9 47DAW + 33.4 45RL + 39.4 44RL (DRL, length of distal root in molars.

Test situations are relatively specific and are experienced by everyone. The major purposes of this overview are to review the current concepts and theories of test anxiety and based on this review to suggest future directions in test anxiety theory and research. Test anxiety can be explained in terms of drive-oriented approach. trait-state anxiety theory, cognitive theory, cognitive and emotional approach, and psychodynamic theory. Usually, high test-anxious students keep the following characteristics : 1) The test situation is seen as difficult, challenging and threatening. 2) The individual sees himself as ineffective, and inadequate in handling the task at hand. 3) The individual focuses on undesirable consequences of personal inadequacy. 4) Self-deprecatory preoccupations are strong and interfere or compete with task-relevant cognitive activity. 5) The individual expects and anticipates failure and loss of regard by others. Future directions in test anxiety research should be focused to elucidate the nature and construct of test anxiety and the etiological factors of test anxiety by conducting research on the relationship between parental or social attitude and test anxiety. The effects of test anxiety on memory, attention, and cue utilization should be performed to elucidate the relationship between test anxiety and performance.

Using data from 2011 Elderly Living Condition Survey database, this study analyzed risk factors for suicide ideation of Korean elderly persons. The analysis sample consists of 10,003 cases. The main purpose of this research was to explore the effects of social quality factor on suicide ideation of Korean elderly persons. Analysis results show that gender, age, area of residence, living alone, subjective standard of living, activities of daily living(ADLs), and geriatric depression are significant predictors of suicide ideation. Key findings are that social quality factor such as experiencing feeling hurt from others' words and actions like avoiding conversations, disregarding one's opinions, pretending to be not heard, getting irritated, grumbling, etc. has the largest effects on suicide ideation. Analysis results imply that without improving social quality, it would not be possible to lower elderly suicide rate.
