The purpose of this study is to investigate about security service history on 1930s in Korea. This study used materials by historical facts for the regulations, books and newspapers in 1930s. In 1930s, security service was unknown details of the historical contents so far. There are four parts conclusion of this study: police department of provisional government, security service agency in the provisional government, security service agents of an independence movement, the general society of Korea. Firstly, Korean regional government in Manchuria, which Kokminbu(國民府) organized the security service agency(警護局) for protect government and public security. Most importantly, the security service agency appearanced an important place which were the independence movement and self-governing administration for Koreans in Manchuria. And the security service agency was required by the security service regulations(警護條例) as law. Secondly, diversity activities of security service in police were exposed the duty as 'car escort service(車輛警護)' for offenders, the 'township office guard' from mobsters, 'woodland protect service(林野警護團)' for fire-raisers. security service as police officer were widely application for protection and safety from danger. Thirdly, Mass society was needed to service for public security in daily events such as 'noted singer meeting', 'funeral procession to the graveyard', 'athletic meeting' as private establishment of security service agency in nowadays. people were wanted the private security service(私警護) from 1930s to present. Fourthly, Overseas security service mentioned in attack of politician, protect from poison and security service about train vessel fleet. In 1930s, security service is comprehensive protection which were not only bodyguard, but also safeguard for hazardous materials.

The Purpose of this study was to grasp the status of drug uses in college students, and to investigate the knowledge and attitude when they use it. We collected through questionnaires from Sep. 1 to Oct. 30 in 1999. The subjects were 490 college students in Seoul and northern of the Kyunggi-do. The data analysis was performed using SPSS (version 7.0) and ANOVA. The results of this study were as follows. 1. There was no correlation for all factors in the relationship between general characteristics of subjects and knowledge for drugs. On the contrary, in the relation of the general characteristics and attitude for drug of subjects, some factors are statistically significant e.g., department (F=3.049, p<.010), satisfaction for school life (F=6.167,p<.002), body shape(F=8.092, p<.000), and the relationship with ones parents (F=3.728, p<.005). 2. In the analysis of drug use status and knowledge, only in the factor of administration control was statistically significant(F=4.304, p<.014) and in the relation of attitude for drug uses, drug administration was statistically significant (F=4.521, p<.004). 3. In the mean scores for the drug knowledge analysis, the highest factor was 'A narcotic make deformed persons through poisoning of physical and mental' (M=4.14), the lowest factor was 'If catch the flu during the pregnancy, should be take drug as possible as quickly to reduce negative effect for fetal' (M=1.94). 4. In the analysis for drug attitude, the highest factor was 'A drug is alike a poison' (M=3.48), 'Should be keep the usage and dosage of drug' was the lowest (M=1.48). 5. From the investigation for status of drug use, it was revealed that the most subjects (73.6%) were purchase drugs after explain their symptoms to pharmacist. And they take drugs only when they felt painful in 43.1%. The most students (70.4%) were experienced control of drug administration. It was inquired that subjects were mainly obtained information about drugs from pharmacist and television (or radio) advertisement, 33.5% and 33.1%, respectively. In the examination for existence of long-term administrators in their family, 'none' and 'only parents' are 49.6% and 37.3%, respectively. When their parents have illness, the persons go to drugstore and hospital for heath-care, 47.8% and 44.3%, respectively. On the basis of results of this study, we suggest as follows. 1. This study was analyzed data from questionnaires for college students in a part of local areas, so we suggest that the next research should be perform for national-wide students as subjects to generalize the results. 2. It is need more intensive research methodologies such as interview and observation. 3. Additional research is required for knowledge and behaviors of drug uses that will how impact on ones health behavior.

The mushroom production reached to 1000 billion won in monetary value in Korea. We, however, do not have systematic terminology dictionary published yet. Recently new varieties of medicinal mushrooms in addition to culinary mushrooms are being introduced steadily through out the world. This makes the necessity of coordinated and consistent arrangement of terms involved in culture, cultivation and physiological aspects of mushrooms. Various components in relation to the medicinal and physiological functionality also poses ambiguity in terminology along with the terms used in breeding and genetic researches. Moreover, some of the scientific terms are being used erroneously. In order to help mushroom cultivators, students, and mushroom business personnel in understanding the terms on mushroom science and technology we intended to collect and organize all the terms related to mushroom morphology and cultivation, poison and medicinal functionality, processing and utilization, and so on. Thirteen professionals from each field participated in this project. The fields included here are : 1) Genetics and breeding of mushrooms, 2) Cultivation and physiology of mushrooms, 3) Taxonomy and ecology of mushrooms, 4) Processing and functional components, 5) Blight and insects of mushrooms.

Spiders are carnivores that prey upon insects and other small arthropods through digestion of food outside the body. Although spider poison may contain proteolytic enzymes, these are thought to play an insignificant role in actual digestion. The source of active proteolytic enzymes can be either the digestive tract cells of spider, or natural microbial flora in the digestive tract of spider. In this study, digestive tracts from the spider, Nephila clavata, were screened for bacteria that have protease or lipase activity. A total of $10^3-10^5$ CFU was recovered from a spider and more than 90% of them showed protease and lipase activity respectively. Of the microbial isolates, 63.3% showed protease or lipase activity, and 50% of these showed both protease and lipase activity. Some of the isolates were characterized using a battery of chemical, phenotypic and genotypic methods. Eleven Gram negative bacteriaa (Acinetobacter calcoaceticus, A. haemolyticus, Alcaligenes faecalis, Cedecea davisae, C. neteri, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas fluorescens, Serratia marcescens, Stenotrophomonas maltophilia, Suttonella indologenes) and 11 Gram positive bacteria (Bacillus cereus, B. coagulans, B. pasteurii, B. thuringiensis, Cellulomonas flavigena, Corynebacterium martruchotii, Enterococcus durans, E. faecalis, Micrococcus luteus, Staphylococcus hominis, S. sciuri) were identified.

In this study, we reviewed a group of marine biotoxins, namely yessotoxins (YTXs), focusing on their causative organisms, contaminated shellfish, domestic and foreign management status, and analytical methods. Although YTXs have not yet been reported in any cases of seafood contamination in South Korea, it is necessary to implement preemptive measures through continuous monitoring because there is a potential risk, due to the introduction of toxic microalgae associated with climate changes and the introduction of contaminated seafood from various countries. YTXs are produced by dinoflagellates, such as Protecratium reticulatum, Gonyaulax polygramma, Gonyaulax spinifera, and Lingulodinium polyedrum, all of which are species found along Korea's coastal areas. Analysis of YTXs in shellfish samples is mainly performed by use of LC-MS/MS after methanol extraction and SPE cartridge clean-up (HLB or strata-X). In the case of lipophilic marine biotoxins, including YTXs, pectenotoxins, and azaspiracids, the extraction and purification procedures are similar. Thus, it seems that the simultaneous analysis of several lipophilic marine biotoxins in shellfish samples is possible, and optimization is necessary. In addition, continuous monitoring studies on causative marine microalgae for YTXs in Korean coastal waters and contaminations in domestic and imported seafood are needed.

Pt/C powder which was used as electrocatalyst in a Phosphoric Acid Fuel Cell(PAFC) was fabricated by colloid method. It was reported that the sulfur from reductant, $Na_2S_2O_4$, worked as a poison against catalyst during long term operation. To remove these sulfurs, we try to treat Pt/C powder by three different methods. First, we tried to remove the sulfur according to temperature and time in $H_2$ atmosphere. As the heat treatment temperature is raised up, the effect of the removal is increased but the electrode performance is decreased because of the growth of Pt particle size. The optimal heat treatment temperature is $400^{\circ}C$, the size of Pt particle is approximately $35{\sim}40{\AA}$ and the electrode performance is $360mA/cm^2$ at 0.7 V. At $400^{\circ}C$, even though the time of heat treatment is extended, size of Pt, amounts of remaining sulfur and electrode performance is almost constant. Secondly, when we removed in a crucible at $900^{\circ}C$ the removal of the sulfur was not better, but the size of Pt particle, approximately $80{\AA}$, was smaller than that of heat treatment in $H_2$ atmosphere at $900^{\circ}C$. Lastly we treated with solvents such as acetone, benzene, and carbon disulfide. It was observed that sulfur components were removed partly by extraction with solvents, the electrode performances were similar each other.

Purpose: Antidotes for toxicological emergencies can be life-saving. However, there is no nationwide stocking and delivery system for emergency antidotes in Korea. We report on a two-year experience of a nationwide stocking and delivery trial for emergency antidotes at emergency departments in Korea. Methods: An expert panel of clinical toxicologists reviewed and made a list of 15 stocked antidote. These antidotes were purchased or imported from other countries and delivered from 14 antidote stocking hospitals nationwide 24 hours per day, seven days per week. Results: From August 1, 2011 to April 30, 2013, 177 patients with acute poisoning, with a median age of 48.5 years, were administered emergency antidotes. The causes of poisoning were intentional in 52.0% and 88.0% were intentional as a suicide attempt. Regarding clinical severity, using the poisoning severity score, 40.7% of patients had severe to fatal poisoning and 39.0% had moderate poisoning according to clinical severity. The most frequent presenting symptom was neurologic deficit, such as altered mentality (62.7%). alerted mentality (62.7%). Emergency antidotes were administered as follows: methylene blue (49 cases), flumazenil (31), N-acetylcysteine (25), glucagon (17), 100% ethanol (15), cyanide antidote kit (12), anti-venin immunoglobulin (5), pyridoxine (4), hydroxocobalamine (2), and deferoxamine (1). The median time interval from antidote request to delivery at the patient's bedside was 95 minutes (interquartile range 58.8-125.8). Conclusion: Findings of this study demonstrated the possibility of successful operation of the nationwide system of emergency antidotes stocking and delivery in Korea.

To enhance the control efficacy against cockroaches in dwelling space, repellent ("Push") was set down on one comer and a poison bait including attractant ("Pull") was on the opposite side. And we tested the control efficacy of Push-Pull strategy by behavior-stimuli of cockroaches. In a mini-field test, German cockroach males primarily chose shelters nearest to the attractant-treated surfaces and farthest from the repellent-treated surfaces. The consumption of food or bait was also highest from food nearest to the preferred shelters by push-pull effect. We evaluated the push-pull insecticidal efficacies of five essential oils belong to Citrus plant, namely, grapefruit, lemon, lime, orange, and petitgrain. The combined push-pull treatments appeared to be faster and higher insecticidal effects than single (pull) treatment, and the repellent efficacy of Citrus oils was in the order of grapefruit > lemon > lime > orange > petitgrain. Therefore, we propose the effective control of the german cockroach using Citrus oils as repellents and push-pull method into a limited area.
