BACKGROUND: Food Sanitary Act establishes Maximum Residue Limits (MRLs) of pesticides in food that are newly registered and used per each quarter, as stipulated by Agro-chemical Control Act. Current Food Code contains the MRLs for a total of 418 pesticides in 184 food types. METHODS AND RESULTS: National MRLs for pesticides have been established by based on scientific data of good agricultural practice, acceptable daily intake (ADI), food intake, average body weight and others. MRLs for pesticides are generally set under the principle that theoretical maximum daily intake (TMDI) are always below ADI. As results, 27 MRLs in agricultural products were newly proposed for 22 pesticides (fungicide: azoxystrobin, fludioxonil, fluquinconazole, flusilazole, iprovalicarb, kresoxim-methyl, mandipropamid, metconazole, pyraclostrobin, tebuconazole, triflumizole, etc., Insecticide: dinotefuran, flubendiamide, indoxacarb, cyhalothrin, spinetoram, thiacloprid, thiamethoxam, metaflumizone, etc., Acaricide(miticide): cyenopyrafen, lufenuron) in 2010. CONCLUSION(s): There is no intake concerns for establishment of pesticide MRLs on foods in this time. Because the ratio of theoretical maximum daily intake (TMDI) are set below that of ADI.

A variety of customized marketing strategies are being implemented in the telecommunications market, including the offering of gifts to consumers, as competition in the market is being restructured with the focus on bundled products. However, the Korea Communications Commission (KCC) has recently imposed fines for user discrimination on telecommunication carriers whose marketing strategies have included the award of excessive prizes. In that regard, various issues related to the suitability and appropriate limit of the current gift regulation in the telecommunications market have been raised. Since the Fair Trade Commission, which had a similar scheme to that of the KCC, abolished the regulation on gifts in July 2016, disputes have arisen as to whether the current regulation on gifts is practically effective from the perspective of consumer benefit. In other words, discussions on the rationality of the theoretical and empirical grounds for the regulation on gifts only in the telecommunication market but not in other commodities markets have begun. As such, this study aims to empirically analyze the suitability of the current regulation on gifts in the domestic telecommunications market under the new competitive environment centered on bundled products, and to seek the rational improvement of, and infer the implications for, the regulation on gifts in the telecommunications market based on the results of the analysis.

This is a study of Jinminso. The purpose of the study is to search and analyze the documents about Jinminso. The data is composed with the first hand historical documents both government documents and civil newspapers which are searched by internet. Based on the documents found, it is safe to say that Jinminso has existed and functioned as an indoor almshouse for the poor. It was established in June 25, 1898 by civil people with donated money in order to reduce the burden of Emperor and to share the love and care for their people with a brotherhood mind. The Jinminso resident were the poor, the sick, the orphans, widows, elderly living alone, and the disabled. They received food, clothes, and shelter. However, Emperor Gojong ordered to shut down Jinminso, and it was closed in Sept. 25, in 1898. The main reason was inappropriate collection of money for the agency operation from the merchants. When Jinminso was closed, all the inmates became homeless. The founders asked to reopen it, and it was accepted but this time was opened as a government agency in 1899. Jinminso imposes great meanings. One, Jinminso was not just an office but a direct service agency housing hundreds of poor people; two, poverty was understood as social problem not just a local district problem; three, rules and regulations were prepared to set up a system of modern age social welfare. The findings provide a clue how the government and society perceived poverty and the poor during the time of late 1800s to early 1900s. The existence of Jinminso will pose many new question.

Due to the rapid developments of South Korea, local communities have faced various social pathologies which generated more violent crimes and criminalized younger students. Several horrendous violences, such as a Kangneung Girl assassination assault case in July 2017 and a Busan Girls assault case in September 2017, happened only between young students. This ignited a public uproar and people were more interested in related national policies and voiced for stronger penalties in ways that punish student offenders and abolish the juvenile law. In this respect, various effective policies are needed to prevent the school violence and to eliminate the students' fear of crime. These are expected to create an environment where students could enthusiastically study in a safe environment. Focusing on elementary school students, this study seeks to empirically analyse the effects of their perception of local crime control governance on their fear of crime and, subsequently, to suggest policy implications which could prevent future school violence and juvenile crimes and reduce the students' fear of crime. The results of this study are as follows: First, the analysis of the general fear of local crime control governance and the fear of crime showed that elementary school students' trust in police officers had a significant effect on the general fear. Second, the analysis of the local fear of crime control governance and the fear of crime highlighted that their trust in the police, social ties, intimacy between the police and residents had a significant effect on the specific fear. Therefore, this study is applicable in reality in that it can contribute to the prevention of school violence and reduction of fear of crime by constructing local crime control governance.

According to the Security Services Industry Act security guards are not just workers but security-related service workers complementing the lack of police force and specializing in protecting of national important facilities, industrial facilities and apartment houses. Nevertheless, confusing or mixing the security service workers in "Security Services Industry Act" with the guards in the "Act on the Protection etc. of Temporary Agency Workers" lead to a constant debate about the scope of work of security guards. In the case of security service workers in "Security Services Industry Act" there is a strict limitations on security service worker's qualification such as strict reasons for disqualification, a need to pass training for new workers and qualification training, a need to report to the competent chief police officer if the security guard has placed or unplaced by the security service company. It distinguishes security service workers in "Security Services Industry Act" from the guards in the "Act on the Protection etc. of Temporary Agency Workers" and acknowledges the occupation of security service worker as a professional service worker. Therefore, security service workers in "Security Services Industry Act" shouldn't be obliged to do any other work than security work. If it is required to do other work than security work contract by the "Security Services Industry Act" doesn't apply but need to use a security guard according to "Act on the Protection etc. of Temporary Agency Workers" or hire a security guard on the employment contract. In this way, when security service workers in "Security Services Industry Act" are recognized as professional security related workers, the entire security industry can ultimately develop.

This study examines why follow-up investigative programs about the sinking of the Cheonan Patrol Combat Corvette(ROKS Cheonan) have not been produced, despite much speculation surrounding the cause of the sinking since November 2010, when KBS investigative program, In-Depth 60 Minutes which had covered the incident was aired. We have uncovered four reasons through a series of in-depth interviews with producers and reporters, as follows. First, Korean military authorities monopolized relevant information, while the producers could not prove or confirm the validity of the findings of the JIG(Joint Civilian-Military Investigation Group)'s report because the facts had been revealed partially and selectively by the authorities and the press' scientific investigation were rejected by the authorities. Second, the crew of In-Depth 60 Minutes was subjected to severe disciplinary action by the Korea Communications Commission. This caused a chilling effect, - it broke the producers' resolve to further explore the reason behind the sinking. Furthermore, the screening of the investigative documentary, Project Cheonan Ship was cancelled without prior notice, presumably by the power of the State and markets. Third, the reorganization and shake-up of personnel by broadcasting stations' presidents appointed by the power of the State crushed the spirit of PD Journalism. Finally, the "red purge" factions stigmatized by the political or military, or the mainstream press, caused the producers or broadcasters to engage in self-censorship. The idea has been used in Korea as a smoke screen to deflect public attention. Nevertheless, the producers hope to shed light on the Cheonan sinking incident and to prove reasonable doubts by pursuing follow-up investigations.

Experiments were carried out to pursue the availability and the feasibility of utilizable cellulosic materials as substrate for the production of cellulosic single cell protein. The resuluts were obtained as fellows. 1. Effects of carbolydrates as a sole carton source on the growth of Cellulomonas flavigena KIST 321 were examined. The result showed that cellulose and xylose would be most utlizable for cell mass production. 2. Alkaline treated waste papers and clothes resulted in good growth of the organism than intact ones did. However the waste papers as substrate of cellulosic fermentation were not digestible, even if the meterial was treated with alkalies. 3. Rice straw, rape straw and panic grass appeared to be good substrates for the cell mass production. 4. Leaves were proved to be a good substrate for the cell mass production, but wood sawdust was hardly digested by merely alkaline treatment. 5. When cellulosic wastes as the substrate were examined into the concentration of alkaline solution, the result suggested that the best productivity of cell mass from cellulosic materials was obtained on treatment with 0.8∼1.0％ NaOH solution. 6. The productivity of cell mass was increased by washing out with water after alkaline treatment of newspaper, pine sawdust, lime sawdust and pine leaf.

The purpose of this study was conducted to investigate the perception and attitude toward physical restraints among elderly care workers. The subjects were 153 care workers who are working at elderly care facilities within the regions. Data were collected by structured questionnaires. Collected data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test and Pearson Correlation Coefficient. The mean score of the perception for physical restraints was 2.83 out of 5, and the mean score of the attitude for the physical restraints was 3.56 out of 5. There was a statistically significant positive correlation between the perception and attitude about physical restraints (r=.31, p<.001). This research has confirmed that it is necessary for care workers to have education about low score items of recognition and attitude about physical restraints. Therefore, we need to develop proper and efficient educational program about use method for physical restraints, and need to develop guideline for adopting physical restraints. Also, we should make efforts and attentions to reduce or abolish physical restraints in order to protect the elderly human rights.
