Nowadays contents of crimes are complicated and diversified because of differentiation and specialization of society. For this reason, special judicial police officer system that each special field officers investigate crimes related to their special fields is introduced to produce high quality private law service. Nevertheless, special judicial police officers who deal with fire crimes show many problems because they have less experiences and ability about investigation than general judicial police officers. Then, purpose of this study is deduction problems by analyzing cases of fire crimes and suggesting improvements which are ways to improve special judcial police officers's who investigate fire crimes efficiencies and professionalisms. Problems about investigation of fire crimes are absence of professional investigation agency, a shortage of professional workforce, absence of professional investigation officers education system. Improvements are creation professional investigation agency, securing experts, developing professional investigation officers education system, construction professional techniques manage system, introduction fire crime cases manage system.

Objective: The purpose of this study was to evaluate factors associated with inpatient admission following 2-level cervical disc arthroplasty (CDA). A secondary aim was to compare outcomes between those treated on an inpatient versus outpatient basis. Methods: Using data from the American College of Surgeons National Surgical Quality Improvement Program database, multivariate logistic regression analysis was used to assess the independent effect of each variable on inpatient or outpatient selection for surgery. Statistical significance was defined by p-values <0.05. The factors considered were age, sex, body mass index (BMI), smoking status, American Society of Anesthesiologists physical status classification, and comorbidities including hypertension, diabetes, history of dyspnea or chronic obstructive pulmonary disease, previous cardiac intervention or surgery, steroid usage, and history of bleeding. In addition, whether the operation was performed by an orthopedic or neurosurgical specialist was analyzed. Results: The number of 2-level CDA procedures increased from 6 cases reported in 2014 to 142 in 2016, although a statistically significant increase in the number of outpatient cases performed was not seen (p=0.2). The factors found to be significantly associated with inpatient status following surgery were BMI (p=0.019) and diabetes mellitus requiring insulin (p=0.043). There were no significant differences in complication and readmission rates between the inpatient and outpatient groups. Conclusion: Patients undergoing inpatient 2-level CDA had significantly higher rates of obesity and diabetes requiring insulin than did patients undergoing the same procedure in the outpatient setting. With no difference in complication or readmission rates, 2-level CDA may be considered safe in the outpatient setting in appropriately selected patients.

In order to infer whether the Special Act on the Punishment of Child Abuse Crimes, etc. actually brought about a change in the social perception shared about child abuse in our society, we used big data to examine the change in the perception of child abuse by the public. This study selected 'child abuse' as the keyword and collected and analyzed. The results of this study are as follows. First, before the implementation of the Special Act in 2013, the words "china" are kindergarten, teacher, body, problem, reporting obligation and neglect compared to the following. After the implementation of the special law, daycare centers, incidents, eradication, campaigns, domestic violence and preventive education were newly introduced. Second, the interconnection of key words in the previous picture of 2013 shows that the left group focuses on measures to introduce to prevent child abuse while the right group consists of keyword intended to view child abuse in conjunction with domestic violence. They are still seen as a group of divorces, discipline, neglect and parental education, which they still perceive as a family problem. Since the implementation of the Special Act in 2013, it will be divided into four groups, and the top group will be highlighted by the keyword related to child abuse cases, part of suspected cases and awareness of child abuse. In addition, the Act on the Special Cases of Child Abuse and the Child Protection Agency clearly appear as a child protection system.

In Korea, child abuse in child care centers occurs continuously, and it is becoming a social problem. The government has intensified the supervision of management in child care centers, and through strong countermeasures and prevention against child abuse, it enacted the special act on child abuse in oder to enable children to become healthy members of society. In this study, this researcher gasped the legal application on child abusers, and analysed how the punishment for abusers changed according to the application of the special act on child abuse, through examining precedents of child abuse in child care centers. 21 cases related to child abuse cases were collected by searching homepage of the supreme court and each district court in this study. As a result of analyzing the precedents, the sentence of the defendant did not increase greatly, and it differed from the criminal identification of the people in cases of child abuse on which the special act on child abuse was applied. Therefore, it can be seen that there is a demand for more rigorous legal application for abusers in order to prevent child abuse in child care centers.

Objectives: Minamata disease was an environmental health disaster of worldwide notoriety that occurred in Japan. The acknowledged patients total roughly 3,000, and the relieved victims currently include 77,099 cases. Still, many cases await acknowledgment or relief. The humidifier disinfectant issue is an environmental health catastrophe that took place in Korea. Over 9.98 million products spanning 43 brands of humidifier disinfectant have been sold and 835, cases have been recognized to date as relevant victims by the government. So far, 2,144 cases have been relieved by the fund of the producing companies. Four million consumers and 560,000 victims are estimated. Finding hints as to how to develop solutions in terms of fact-finding and prevention are the objectives of this study. Methods: Fields visits, interviews, and workshops as well as reference reviews have been conducted. A comparison was attempted to show the similarities and differences between the two disasters on 38 items. Results: Apparent similarities in the two disasters are the failure of industrial safety measures and governmental safety systems as well as relief systems for the victims. No comprehensive investigation was performed for all of the affected areas in Japan and all of the consumers in Korea. Both governments have tried to hide the faults and responsibilities of the companies and minimize the scale of the victims. Only after the government was changed through a general election did the new governments apologize and attempt to find political and social solutions through special relief laws. Conclusions: Over the process of each event, in the beginning, debates took place regarding the cause and the heath damages involved. For both, medical and toxicological relations are the keys while afterward finding a social solution became the subsequent issue.

The object of this paper is to compare the accuracy and the characteristic of various methods of solving the geodetic inverse problem for the geodesic lines which be in the standard case and special cases(antipodal, near antipodal, equatorial, and near equatorial situation) on the WGS84 reference ellipsoid. For this, the various algorithms (classical and recent solutions) to deal with the geodetic inverse problem are examined, and are programmed in order to evaluate the calculation ability of each method for the precise geodesic determination. The main factors of geodetic inverse problem, the distance and the forward azimuths between two points on the sphere(or ellipsoid) are determined by the 18 kinds of methods for the geodetic inverse solutions. After then, the results from the 17 kinds of methods in the both standard and special cases are compared with those from the Karney method as a reference. When judging these comparison, in case of the standard geodesics whose length do not exceed 100km, all of the methods show the almost same ability to Karney method. Whereas to the geodesics is longer than 4,000km, only two methods (Vincenty and Pittman) show the similar ability to the Karney method. In the cases of special geodesics, all methods except the Modified Vincenty method was not proper to solve the geodetic inverse problem through the comparison with Karney method. Therefore, it is needed to modify and compensate the algorithm of each methods by examining the various behaviors of geodesics on the special regions.

Purpose - Previous studies examined effects of sharing economy in the fields such as accommodation and automobile sector, while there are lack of researches in the field of skill-sharing economy. By classifying skill-sharing into general and special skill-sharing, this study explored effects of variables such as transaction utility, social utility, sustainability utility, emotional utility, economic utility, and trust utility, on attitudes, intention, satisfaction, and loyalty of demand (i.e., customers) and supply (i.e., providers) sides, potential, and actual customers. Research design, data, and methodology - Data were collected via both online and offline surveys. This study applied factor analysis and multiple regression analysis for findings. Results - Results show that utilities for general suppliers' skill-sharing are significant than other cases. Among utilities, this study found that trust utility shows significant for the cases of special customers', general suppliers' and special suppliers' potential skill-sharing. The results implies that trust is crucial in the transaction of the sharing economy. Conclusions - Enhanced managerial systems help resolve issues on the sharing economy. This study provides implications what are positive effects of skill-sharing economy and recommends proper establishment of the sharing economy.
