This paper is concerned on the reality and the effected factors to the help for the victims of crime in the police. In our society the related enacted law and polices for the victim of crime have been practiced, but it was not easy to be helped or supported in some ways. On the contrary the victims have been used as tool of investigation or just the sources of witness on the crime. These days the issue of the victims of crime is one of the most concerned matters to the public, and it turns to on of core issues in the law enforcement community. According to the filed survey for the study, the female and higher level or longer careers than the male and lower level or shorter careers in the police are more positive on the help for the victims of crime. But if the members in the law enforcement community would be trained up with the organized program to fulfill their duties, they could be in positive on the help for the victimes of crime.

This study is concerned on Why The Certified Security certification is needed and How to control the security quality to get better service to the clients. Theses days are required The Certified Certificate in all the industry. And in this point of view, the certified certificate is a kind of confirmation by an authority to the person who has how much special knowledge and practice in a certain field. Moreover, in the functionalism society the certified certificate system would be very positive effect to the related industry and society as official measurement by an authority. The security is freedom from fear and anxiety. Which means the security can not be operated in isolation from citizen's safe-living expectation, and which is also dealing with valuable human being's life. For getting the better purpose the security industry employees should have more organized special training and education. As my understanding the certified certificate exam system is the confirmation by an authority, the certified certificate is only neutral evidence to get the confidence and credit from the clients. In this point of view the core point is How to control The Certified Certificate by a credied authority.

Purpose : To evaluate tile frequency of urinary tract anomalies in male neonates less than 3 months old who presented with urinary tract infection(UTI) and to evaluate a appropriate imaging approach after first UTI. Materials and methods : During a period of 5 years from March 1994 to February 1999, 65 male infants less than 3months old(range: 4-92 days, mean: 43 days) with UTI were evaluated. Ultrasound(US) and Voiding cystourethrogram(VCUG) were done in 60 patients. Due to refusal and technological problem, 5 patients were missed. 99mTc-dimercaptosuccinic acid renal scan (99mTc-DMSA renal scan) was recommended to most patients but performed in 40 patients. Renal scan was performed at least 3 months later after urinary tract infection. Results : Urinary tract anomalies were found in 26 of 65 infants. Twenty-six had vesicoureteral reflux(VUR), two had both VUR and double ureter, two had both U and posterior urethral valve. In patients with VUR, eight had renal scar or renal atrophies. In case of renal scar or atrophy, grades of VUR were III or above. Conclusion : We suggest that US and VCUG should be routinely performed in infants(<3months)with first UTI. 99mTc-DMSA renal scan should be performed only when renal parenchymal damage was observed in US and VUR grade III or above in VCUG.

Under the hypothesis that social behavior appears with personal differences. this study tried to make it clear that sociality factors are precedence variables, through characterization of the relationship between university students' sociality factors and multidimensional leadership factors. To achieve this goal, we have selected as a population university Taekwondo players participating in playing currently in 2006, sampled 228 subjects using the convenience sampling, and then finally used their data. Data were processed through descriptive analysis, factor analysis reliability analysis, correlation analysis and multiple regression analysis using SPSS 12.0, and conclusions were drawn as follows. Through such a process and method, we have yielded the following results. First, the responsibility our of the sociality factors appears to have significant influence on the types of training & direction, positive feedback, and social support at the level of p<.001, on the type of authoritative behavior at the level of p<.01, and on the type of democratic behavior at the level of p<.05. Second, the sociability out of the sociality factors proves to have significant influence on the type of training & direction at the level of p<.05. Third, the planning out of the sociality factors turns out to have significant influence on the type of social support at the level of .001, and on the types of democratic behavior and authoritative behavior at the level of p<.01.

The purpose of this study is to verify the validation of the Korean-type destructive leadership scale in order to activate the leadership research of local police manager in Korea. For the purpose of this study, the entire police officer(under the rank of sergeant) working at the Gyeongnam Provincial Police Agency in 2017 was set up as the population. A proportional allocation sampling was used for the sampling, and the allocation standard was set up in the workplace, department, rank, and sex. Data collection was conducted from April 1, 2017 to April 30, 2017, for a total of 500 respondents, and 433 were finally used for actual analysis. In the study, reliability and validity of destructive leadership scale were verified through reliability analysis, exploratory factor analysis, and confirmatory factor analysis. As a result, the destructive leadership scale of Korean local police manager showed a high cronbach' ${\alpha}$ coefficient of 0.948 for the questionnaire related load and 0.974 in the questionnaire related organization, but, the model fit of confirmatory factor analysis was low. Therefore, through additional exploratory factor analysis and confirmatory factor analysis, we reconstructed 6 questionnaires by deleting 4 questionnaires among the load-related items. On the other hand, the organization-related items were verified to be appropriate for all of the existing 10 items, and the destructive leadership scale of Korean local police manager was finally reconstructed into 16 items with 2 factors. This study also confirmed that the above reconstruction model is statistically suitable. The destructive leadership scale of Korean local police manager can be used as the basic data of leadership research to be conducted in the future.

The purpose of this study is to explore the underlying causes of the development of private security in the United States. These include the increasing crime rates and fear of crime, the poor performance of public policing, the decentralization of political authority, the increase of mass private property, economic growth and increase of personal income, commodification of security, insurance companies' demand for tighter security and fear of litigation, and historical events such as World War I & II. Based on the findings of this study, it is suggested that no single factor would account for the growth of private security in the United States. In other words, the rapid growth of private security in the United States should be attributed to the interrelated influences of the factors given above. Finally, it might be the contribution of this study that the future development of private security in Korea would be guided by understanding the case of the United States because of the similarities of the developmental process in private security industry of two countries.

In this paper, through a digital potentiometer and exponentially weighted moving average filter, pulse and PPG waveform measurable device was fabricated in radial artery. If this device is not proper about signal size in analog part, MCU can judge easily by adjusted amplification through digital potentiometer, using exponentially weighted moving average filter is able to filter out more clear value of ADC. I presumed pulse rate as value of measuring time between point of maximum contraction from sensing signal in radial artery of wrist. Therefore, this means can measure stable pulse rate and PPG waveform, finger as well as radial artery, whether signal size of each person is different finger as well as radial artery.

This paper is concerned with the influence in the job satisfaction by the organization, the job specialty and the self-devotion in the special duty of private security. Today's society is required more intensive security in the diversity, the complexity and the uncertainty, but the public security service could not supply enough for what the society requires. In this circumstance more specialized and special trained security services are demanded from private security industry. With the concerns, this study is based on actual survey. The study is telling us that there is much relationship in job satisfaction between each element. Which means that 1) there is some different from personality, 2) there is much influence in self-devotion by job specialty, 3) there some effectiveness in job satisfaction by job specialty, 4) there is some influence in job satisfaction by self-devotion, and 5) job satisfaction is affected by job specialty and self-devotion.
