Excellent deep drawability and strain aging rsistance are obtained by the addition of alloying elements such as Ti and Nb which can form carbide and nitride easily into Al killed extra low carbon steel. Recrystallization textures and mechanical properties of the three different extra low carbon steels with B containing Nb only, Ti only, and both Nb and Ti, respectively, along with have been compared. Inverse pole figure shows that (100) and (111) texture intensities of Nb containing steel changed a lot during the annealing treatment and the degree of texture-structural change in the steel containing both Nb and Ti is about the same as that in the Ti-containing 5teel. After annealing the pole figure shows that the {Ill} < 110 > and {112} < 110> textures are the strongest in the cold rolled state and the annealed state, respectively. However, there is little difference in texture structure among the three kinds of steels. There is a tendency that the steel containing both Nb and Ti the grain size of which is the smallest is the highest in hardness. Nb-containing steel is the next and Ti -containing steel is the last in hardness.

The threat of crime became a global issue nowadays. Terrorism, organized crime, crime by nation can be mentioned as typical examples. The crimes in modern society can't be identified to happen when, where and how being different from those traditional crimes(murder, robbery, sexual abuse, arson). This was the result of changed security environment that needs to address wide range of crimes as being indicated sporadic characteristics of modern threat of crime such as terrorism threat targeting unidentified masses as well as the emergence of systemic phenomenon of organized crimes and crime committed by nation. In this regard, the case of 9.11 occurred in 2001 can be deemed as an example that made a dramatic turn around to the security environment. After the terrorism, it provided an opportunity to rethink not only USA but also to the institutions all over the world that deals with crime about gathering, management, utilization of crime intelligence. As a result of which there appeared a change in police activities more effectively in gathering & managing crime information and ILP is the very activity that emerged from the USA/UK countries. This aims police activities to minimize the threat of crime being the system reflecting a framework to manage more directly to control crime by gathering and processing information. In view of the global change of security environment as a common phenomenon, the need to direct to ILP has increased in Korea in line with such security environmental change. Accordingly, this study focused on the method of introduction of ILP and presentation of matters for discussion by reviewing ILP activities of the USA/UK countries.

The purpose of this study is to reconsider whether Temple in William Faulkner's Requiem for a Nun has grown morally. Temple in Sanctuary, the previous work was raped with a corn cob by Popeye and perjured in the court, resulting in Lee Goodwin's brutal death. Now she is now a mother of two children and a wife of Gowan Stevens, but she cannot get out of the past and tries to run away with Pete, Red's brother, but she was resisted by Nancy Mannigoe, a nanny. Nancy tries to stop Temple sacrificing herself and Temple's baby. When confronting Nancy who accepted her death sentence without hesitation, Temple realized her past guilt which never fades out. A lapse of 20 years between Sanctuary and Requiem provides Temple and author himself opportunities for spiritual and moral growth in spite of painful realization that the past is never past. On the other hand, Faulkner tells the history and the past of Jefferson elaborating the description of the courthouse and the jail. Both are correlated in thematic perspective, the former representing humanity's need for security, the latter the opposite impulse toward aggression and destruction. but together represent the presentness of the past and the fluidity of time.

Eleutherococcus senticocus MAXIM containing compounds for a cordial and lumbago is a native plant in this country. However it is generally difficult to propagate them by seed. This study was carried out to improve propagation efficacy by cutting method using Eleutherococcus senticosus MAXIM collected Mt. Odae for three years$('90{\sim}'92)$. Rooting was delayed by 3 to 12 days but callus formation and rooting percentage was high by 75%, 30% respectively in the treatment of Rooton-F powder, a chemical for rooting promotion, compared with non-treatment. Rooting percentage and rooting characters were not differenced by treatment for remove rooting inhibition compounds and soil-media mixured by 1:1 of vermiculite and perlite was suitable for elevating rooting ratio. A. chiisanensis and A. sieboldianum were rooted well in any time to be cut, while rooting activity of E. senticosus was different by time to be cut. Rooting ratio of E. senticosus was 26%, 36% and 60% when cutten March 20, July 20 and september 20, respectively.

The Korean economy successfully overcame the macroeconomic downturns driven from the Asian financial crisis in a very short period of time. The economic shock, however, generated a variety of social problems, one of which was the increase in felonies (homicides, robbery, rape, and arson), or degradation of public safety. We argue that the Korean criminal policy has not been effective to ameliorate the rising trends in crime caused by the financial crisis. In order to substantiate this claim, we assess the effectiveness of criminal policy: policing, sentencing, and corrections. First, there has been resource shortage in policing since the 1997 financial crisis. For the past ten years, the investment of human resource and budget in the police has been virtually stagnant, as well as in prosecutors' investigation activities. The insufficient resource allocation in policing caused a huge decline in arrest rates and prosecution rates. Second, the Korean judicial system has not increased the severity of punishment. Comparing the pre- and the post-financial crisis period, the average length of prison sentence by the courts has declined. Given the degrading in the quality of crime and the decreasing amount of inputs into the policing and prosecution, the government should have increased the severity of punishment to deter crime. Third, we found that the government hired more officers and allocated larger budget into prison and probation. However, it is difficult to suggest that the increased level of resources in correctional programs have been effective in preventing released prisoners from committing future crimes. This is because the number of repeat offenders convicted of more than a third offense increased dramatically since 1997, pushing felonies upward. In sum, the government organizations failed to respond respectively or to make coordinated actions, eventually causing a dramatic increase in crimes. This research brings explicit policy implications. In order to prevent possible additional degradation of public safety, the government must put more efforts into increasing the effectiveness of policy and to investing more resources into said policies. We also emphasize the importance of the institutional mechanisms which foster policy coordination among the Police, the Prosecutor's Office, the Ministry of Justice, and other relevant government organizations.

In this study, the relationship between social support and adolescent mental health was examined. A primary aim was to investigate how family, school, and friends affect adolescent mental health including depression, stress, and anger issues. This study also intended to investigate the indirect effect of these factors through the mediator, problem drinking. The study used survey data collected from the "2010 The Study on Mental Health of Korean Adolescents" conducted by National Youth Policy Institute, and 942 subjects were selected for this study. The study hypotheses were tested using SEM (Structural Equation Modeling) analysis. Analyses revealed that the appropriate functions and roles of the family members had the effect of promoting mental health of adolescents. Inappropriate functions and roles of the family members induced problem drinking, and this eventually had a negative impact on mental health causing depression, stress, and angel problems. Results also showed that having more friends who drink alcohol or smoke cigarette had no direct effect on the mental health of adolescents; however, there was an indirect effect through the mediator variable, problem drinking. The finding of this study revealed the need and importance of appropriate social support system and environment in order to promote mental health of adolescents.

This study was conducted to analyze the change of sex-related knowledges and attitudes of female students after sex education intervention at rural high school. After conducting a pre-survey on 119 subjects of 1st and 2nd grade female students in two rural high schools in November 1999, 150 minute-sex education was provided for the students by health professional from health center. Two follow-up survey were conducted in one month and six months later to evaluate the effect of sex education. The score of knowledge of AIDS was increased from 8.46 in pre-education to 11.90 in one month and 11.87 in six month later. The positive attitude toward the pre-marage sexual relationship was changed from 16.9% in pre-education to 14.4% in one month and 23.5% in six month later. The opinion for the heterosexual intercommunion during school age was not changed by sex education intervention and the subjects were pro for the making male friends during their school period. The subjects were more understood that AIDS patient should be treated humanly and they recognized that the mode of disease transmission and how to prevent the disease. To maintain the effect of sex education, the continuous and regular educational intervention and team approach from school and health professional should be necessary.

Objectives: To compare alcohol secondhand effects among US and Korean students. Methods: Nationally representative 4-year colleges of two countries were involved in this cross-national comparison study. Data from the 2001 U.S. College Alcohol Study and the 2003 Korean College Alcohol Study came from 120 colleges in 38 U.S. states and the District of Columbia and 60 colleges in Korea. Randomly selected 4-year college students from the U.S. (10,924) and Korea (2,385) participated in the study using self-reports of alcohol use and perceptions of drinking as assessed by College Alcohol Study questionnaires. Results: Korean students were tend to more likely to have being a victim of sexual assault or date rape, having to take care of drunken students and finding vomit in the hall or bathroom of residence, than US students, while US students were tend to more likely to have being insulted or humiliated, having a serious argument and quarrel, being pushed, hit, or assaulted, having study/sleep interrupted, and experiencing an unwanted sexual advance than Korean students. Conclusion: In general, US students were more likely to suffer interrelationship problems after drinking while Korean students were more likely to have physical and individual drinking related problems.
