  • The purpose of this study was to develop scale for the measurement of indirect traumatization occurred by social disaster and test their validity. To achieve this purpose, this study conduct a research through the following procedure. First, to develop the inventory, various responses of indirect traumatization occurred by social disaster were gathered from Korean adults participated in open questionnaire. 41 items were made. Second, exploratory factor analysis were performed and 21 items were selected in this step. The Indirect Trauma Scale of Social Disaster(ITSSD) consisted of 4 factors, each with 4-to-8 items, respectively. Four factors include ① private coping responses ② symptom responses ③ distrust responses of world ④ moral emotion cause of social perpetrators. Appropriate levels of reliability were established for the ITSSD. Third, Indirect Trauma Scale of Social Disaster was validated by confirmatory factor analysis, and 21 items were fixed. To 300 participants differed from development step, confirmatory factor analysis was performed. 4 factors structure derived from the exploratory analysis was appropriate. And 4 factors indicated reasonable fit index such as TLI(.913), CFI (.924) and RMSEA(.077). In addition, ITSSD identified a significant positive correlation with Posttrauma Risk Checklist, Korean Depression Scale, State-Trait Anxiety Inventory-KYZ and negative with Acceptance-action Questionnaire-2. But that was unrelated to Forgiveness Trait Scale and Life Satisfaction Scale. Also the result showed that Women experienced high level of indirect trauma of social disaster than men.

  • The purpose of this study was to 1) replicate the Wells effect(i.e., reluctance to rule against the Defendant solely on the basis of probabilistic evidence) in Korea and 2) examine the validity of an Alternative explanation(i.e., perception of risk of wrong verdict). In study 1(n=46), mock jurors in the tire-tracks condition were reluctant to rule against the defendant based on their perceived probability and this pattern was not resulted in the tire-tracks-belief condition. Therefore, the Wells effect was replicated in Korea. In study 2(n=70), we manipulated the participants' perception of risk of wrong verdict. That is, participants who were assigned in the high risk perception of wrong verdict were informed that if the defendant were found guilty, the defendant would get considerable demage both in finance and reputation of the company. Participants in the low risk perception of wrong verdict condition were informed that these demage would not be great. The results revealed that the Wells effect was pronounced in the high risk perception of wrong verdict condition. That is, participants were more reluctant to rule against the defendant when they perceive the significance of the result of wrong verdict as high. Limitations of the study and the directions for future study were discussed.

  • The present study examined the accuracy of polygraph tests through two types of statistical methods with unknown ground truth. One method evaluated the accuracy based on the rates of agreements between polygraph test results of crime suspects and prosecutors' indictment decisions for them. Those crime suspects were tested with polygraph by the Prosecutors' Office of the Republic of Korea between 2000 and 2004. The other method estimated the accuracy by using the latent class analysis based on the frequency distributions of the polygraph results and indictments during 2006. Excluding cases that were 'inconclusive' on the polygraph test, the study showed that the accuracy of the polygraph tests is .914 (SE=.004) for the 2000-2004 data, and .885 (SE=.021) for the 2006 data. With the inclusion of 'inconclusive' cases in the 2006 data, the results from the latent class analysis showed the accuracy in the range between .707 and .734 (SE=.027~.031), with false positives between .078 and .087 (SE=.019~.023), and false negatives between .029 and .078 (SE=.010~.023). The probability that the polygraph test correctly classifies subjects appeared to be in the range between .912 and .925 (SE=.013-.016) for those who lie, and in the range between .867 to .955 (SE=.011-.040) for those who tell the truth.

  • This research measured a concept of mobility which is included objective travel behavior as well as psychological and physical mechanism that influenced travel behavior. And then, this research examined the relation between mobility and the quality of life in elderly drivers. In research 1, to evaluate the reliability and validity of "Mobility Questionnaire(MQ)", we tested "MQ" to 207 drivers aged 20 years and older. In research 2, we examined the mobility level of elderly drivers. Also we investigated the influence that mobility of elderly drivers impacts on their quaility of life. we used "MQ", "Psychological Well-Being Questionnaire(PWBQ)" to 91 drivers aged 65 years and older. To factor analysis, MQ consisted of 'Safe Driving Ability(ADA)', 'Travel Increase(TI)', 'Travel Decrease(TD)', 'Social Activity(SA)', and 'Driving Situational Adaptability(DSA)'. The amount and speed of driving of elderly drivers reduced driving behavior than other drivers. Also, elderly drivers negatively assessed their physical abilities for safe driving and felt a low confidence in specific driving situation. On the other hand, elderly drivers take parts in social activity constructively. A review of the relation of mobility and quality of life showed that mobility of elderly drivers had positive correlation with PWB. Specially, 'ADA', 'SA', and 'DSA' had significant correlations with PWB of elderly drivers. The mobility of elderly drivers had an effect on 'Autonomy', 'Environmental mastery', 'Self-acceptance', and 'Positive relations with others'.

  • Most of the researches on the view of marriage from 1970s until now have merely been the status survey to get a glimpse of thoughts on the marriage of the time. It is true that the recognitions of marriage in the recent days, especially those of the youth are going through a great deal of changes. However, it is also recognized that although westernized views on marriage recently are flooding in, still the traditional perspectives are firmly rooted underneath. Therefore, this study intended to predict the potential conflicts from diversified marital perspectives of the youth in the contemporary society applying the Korean views on marriage as an effort to develop views on marriage in scientific way, analyze the psychological problems before and after marriage, and pursue successful marriage to form a stable and desirable family. As for the method, questions were selected by 275 university students and the validity and reliability of marriage views by 1,283 married couples were examined. As a result, the following conclusions were made. The scale for Korean marriage values were summarized to six factors - 'traditional marriage', 'successful marriage', 'irrationality of marriage', 'necessity of marriage', 'cohabitation', and 'divorce and remarriage', showing high correlation with the existing scales, and the reliability coefficient of each subscale indicated as comparatively reliable with the value of Cronbach α=.88 at Cronbach α=.63.

  • This study presents the process and outcomes of developing mathematical-informatics linkage·convergence class materials, based on previous research findings that indicate a lack of such materials in high schools despite the increasing need for development of interdisciplinary linkage·convergence class materials In particular, this research provides insights into the discussions of six teachers who participated in the same professional learning community program, aiming to create materials that are suitable for linkage·convergence class materials and highly practical for classroom implementation. Following the material development process, a theme-based design model was applied to create the materials. In alignment with prior research and consensus among teacher learning community members, mathematics and informatics teachers developed instructional materials that can be utilized together during a 100-minute block lesson. The developed materials utilize societal issue contexts to establish links between the two subjects, enabling students to engage in problem-solving through mathematical modeling and coding. To increase the validity and practicality of the developed resources during their field application, CVR verification was conducted involving field teachers. Incorporating the results of the CVR verification, the finalized instructional materials were presented in the form of a teaching guide. Furthermore, we aimed to provide insights into the trial-and-error experiences and deliberations of the developers throughout the material development process, with the intention of offering valuable information that can serve as a foundation for conducting related research by field researchers. These research findings hold value as empirical evidence that can explore the applicability of teaching material development models in fields. The accumulation of such materials is expected to facilitate a cyclical relationship between theoretical teaching models and practical classroom applications.

  • This study was intended to validate and develop the driving stress scale. In a preliminary investigation, literature studies on the stress and open questionnaire were administered and examined in four regions in Korea. As a result, 121 items driving stress questionnaire were developed. In the study, this driving stress questionnaire was examined to 450 drivers located seven regions in Korea. The factors analysis revealed 5 meaningful factors[(Progress Obstacle: PO), (Traffic Circumstance: TC), (Accident & Regulation: AR), (Regulation Observance: RO), (Time Pressure: TP)] with 38 items. When internal consistency for each 5 factor was calculated, all sub-scale revealed a satisfactory level of Cronbach's α. Also, correlations with Driving Behaviour Inventory-General Driver Stress(DBI-GEN) and risk driving behaviors(speed driving, drunken driving, offence accident, defence accident) supported consistently validity of the Driving Stress Scale(DSS). Finally the result were discussed and implications are suggested for future studies.

  • This study was intended to validate and develop the driving stress coping behavior scale. In a preliminary investigation, literature studies on the driving stress and open questionnaire were administered and examined in four regions in Korea. As a result, 64 items driving stress questionnaire were developed. In the study, this Driving Stress Coping Behavior Scale(DS-CBS) was examined to 372 drivers located seven regions in Korea. The factors analysis revealed 2 meaningful factors[(Good Coping: GC), (Bad Coping: BC) with 24 items. When internal consistency for each 2 factor was calculated, all sub-scale revealed a satisfactory level of Cronbach's α. Also, correlations with Driver Coping Questionnaire(DCQ) and risk driving behaviors(speed driving, drunken driving, traffic violation, offence accident, defence accident) supported consistently validity of the Driving Stress Coping Behavior Scale(DS-CBS). Also, We investigated the influences of 'Good Coping', 'Bad Coping' consisting of driving stress coping behavior, on traffic accidents risk. As a result, 'Good Coping' and 'Bad Coping' influenced traffic accidents risk. 'Good Coping' had decreased effects, the other side 'Bad Coping' had increased effects on traffic accidents risk(TARI).

  • The purpose of this study is to conduct an exploratory investigation into Korean psychopathy by synthesizing the results of prior domestic research on the validation of psychopathy assessment tools. Domestic research on the validation of psychopathy scales has been constrained by limited research methodologies, bias toward male subjects, and the application of inappropriate factor structures. Furthermore, although discrepancies between the original scale and the Korean scale were identified regarding the factor structures through in construct validity research, discussion on the concept of Korean psychopathy has been limited. As a result, this study compared 16 domestic papers on the validation of psychopathy assessment tools along with 9 international foreign papers that addressed the factor structure of each original scale. By comparing the derived factor structures, items assigned to each factor, and omitted items from each study, the characteristics of Korean psychopathy were explored. The findings revealed that Korean psychopathy is recognizable from materialism, machiavellianism, and antisocial behavior and impulsivity. This study holds significance in synthesizing the outcomes of current domestic psychopathy validation research and offers a conceptual foundation to help understand Korean psychopathy.

The Character and Negotiability of Air Waybill (항공화물운송상(航空貨物運送狀)의 성질(性質)과 유통성(流通性))

  • The air waybill is supposed to be made out by the consignor. If the carrier makes it out, he is deemed, subject to proof to the contrary, to have done so on behalf of the consignor. The air waybill shall be made out in three original parts. The first part shall be marked "for the carrier", and shall be signed by the consignor. The second part shall be marked "for the consignee", it shall be signed by the consignor and by the carrier and shall accompany the goods. The third part shall be signed by the carrier and handed by him to the consignor, after the goods have been accepted. According to the original Warsow Convention article 8, the air waybill must contain 17 particulars or items. However, the Hague Protocol reduced to three the number of particulars required to appear on the air waybill. Only one item is obligatory, namely, the notice that the carriage is subject to the rules of the Warsaw Convention. The absence of the air waybill entails unlimited liability of the carrier because it deprives him of the right to avail himself of the provisions of the Warsaw Convention which exclude or limit his liability. The consignor shall be liable for all damages suffered by the carrier or any other person by reason of the irregularity, incorrectness or incompleteness of the particulars and statements in the air waybill. Although the contract of the carriage of goods by air is not a formal contract, the document of carriage is issued. The issue of air wayhill is not essential for the existence or validity of the contract, but serves merely as a means of proof. The Hague Protocol has lessened the consequences of the carrier's neglect to faithfully accomplish the required formalities. Henceforth, these formalities no longer constitute legal obligations. The air waybill is the consignment note used for the carriage of goods by air. It is often called an air consignment note and is not a document of title or transferable/negotiable instrument. It is basically a receipt for the goods for despatch and is prima facie evidence of the conditions of carriage. Each of the original parts of the air waybill has evidential value and possession of his part is a condition for the exercise by the consignor or cosignee of his rights under the contract of carriage. Oveall, it is an usage that under a documentary letter of credit, the consignee on the air waybill is the opening bank of the letter of credit, and the notify party is the importer who applied for the letter of credit. In Korea there is an usage as to process of cargo delivery in air transportation as follows: The carrier carries the cargo into the bonded area of the airport and gives both the notice of arrival of the cargo and the consignee's air waybill to the notify party who is the importer. Then the notify party obtains the Letter of Guarantee from the opening bank in exchange for reimbursing the amount of the letter of credit or tendering the security therefor to the opening bank. The notify party then presents this document to the customs authorities for the process of customs clearance. The opening bank becomes a consignee only to ensure repayment of the funds it has expended, and the only interest of the opening bank as consignee is the reimbursement of the money paid to the exporter under the documentary letter of credit. Just as the bill of lading in maritime law, the air waybill has always been considered negotiable although the Warsaw Convention does not emphasize this aspect of negotiability. However, the Hague Protocol article 4 corrected the situation by stating that "nothing in this Convention prevents the issue of a negotiable air waybill." This provision officially recognizes that the air waybill must meet the needs of the present day business circles by being a negotiable instrument. Meanwhile, Montreal Additional Protocol no. 4 has brought important changes. Registration by computer is acceptable and the parties to the contract of carriage are allowed to replace the air waybill with a receipt for the goods. In conclusion, as the Warsaw Convention has not details of provisions relating to the issuing of the negotiable air waybill, it is hoped that there should be supplement to the Warsaw Convention and establishment of international commercial usage with regard to the negotiable air waybill.
