During the period of 1962 through 1981, a total of 11. 7 million cummulative acceptors have received contraceptive services under the national family planning program. The number of annual acceptors have steadly increased from 151, 200 in 1963 to 842, 200 in 1975, and since then it has maintained the range of 600, 000 to 800, 000 acceptors per year. From the beginning of the program, the IUD had been the principal method of contraception provided by the government program until 1976, at which time the government made female sterilization services available thorough the introduction of the laparoscopy method. The popularity of female sterilization has increased very rapidly during the last few years. Out of 614, 200 program acceptors in 1981, the proportion of female sterilization and IUD acceptors were virtually the same(26.8% and 27.2% respectively). Considering various anticipated problems such as a large proportion of contraceptive users for the fertility termination and the high discontinuation rates of IUD and other traditional method, the government has emphasized the distribution of female sterilization and deemphasized condom and pill contraceptives since 1978. However, the recent service statistics has revealed that the acceptance rate of female sterilization has steadly declined since 1979. Thus, the purpose of this analysis is to review the current government policy on contraceptive distribution with emphasis of female sterilization by estimating the prospect of sterilization acceptablilty. According to the Fifth Five-Year Plan for Family Planning Program(1982-1986) the annual average target of sterilization was set up to secure 230, 000 acceptors by the government sector during the period. If the sterilization target is to be met as planned, about 80 percent of exposed women aged 30-44 will be remained as sterilized women in 1985. This means the the high acceptance rate of sterilization shown in the past years can not be expected, unless the acceptors' age of sterilization is drastically lowered below 30 years. Accordingly, the current policy on contraceptive distribution with emphasis on sterilization should be gradually changed to encourage target population to use contraceptives for birth spacing by increasing access to such contraceptives as IUDs, pills, and condoms, and to improve continuation rates through better program management system including target setting, acceptors' follow-up, supervision, and evaluation system.

Purpose: This study investigated the use of infection management and the frequency of emergency equipment sterilization by emergency rescue crews to provide basic guidelines and suggestions for infection control. Methods: A self-reported questionnaire was completed by 160 emergency medical technician rescue crews in J area from May 7 to May 22 in 2015. The questionnaire consisted of 95 items, including the general characteristics of the subjects (8 items), the use of emergency equipment (33 items), the frequency of facility sterilization (33 items), infection control (12 items), vaccination (4 items), and the use of personal protective equipment (5 items). Results: In all, 97.3% of respondents were aware of the "Guidelines of Infection management for Rescue Operators' and 90.9% received training on infection control. A total of 72.7% and 47.3% of rescue centers were equipped with disinfection facilities and laundry rooms, respectively. The average frequency of sterilization was $3.17{\pm}0.75$, which significantly differed for teams with more clinical experience (p=.050) and teams with three members (p=.030). The average score for individual protective equipment supplies was $1.95{\pm}0.66$. Conclusion: For proper infection management of emergency equipment, our results suggest that the number of crew members should be increased for each ambulance, protective equipment and rescue products should be supplied, and the number of facilities for sterilization and laundry at rescue centers should be doubled.

The hazard analysis critical control point (HACCP) system was introduced to the Korean livestock slaughter and product processing business in 1997. Ice cream manufacturers focus on the sterilization process in order to reduce microorganism, so the HACCP-accredited ice cream manufacturers particularly set the sterilization process as critical control point (CCP). Therefore, the microbiological test results on the finished products can be considered as one of the indicators which show the level of microbiological control in the ice cream manufacturers. Accordingly, this study was carried out to examine if there is a meaningful difference in terms of the microbiological control level between the HACCP-accredited and non-accredited ice cream manufacturer groups by comparing aerobic plate count (APC) of ice creams. The mean of APC was 1.68 Log CFU/g in the HACCP-accredited ice cream manufacturer group and 2.59 Log CFU/g in the non-accredited ones respectively and there was a statistically significant difference (P<0.05). The test results suggest that the level of microbiological control in the HACCP-accredited ice cream manufactures is much higher than that of non-accredited ones.

In Korea, Strawberry bacterial angular leaf spot disease was first reported in 2010. The disease of strawberry caused serious problem for strawberry producers and export. To field test, we applied the bactericides in June and October as nursery stage and cultivation stage, respectively. In nursery stage with high temperature condition, Oxolinic acid (97.2%) showed significant control effect. In cultivation stage with low temperature condition is soil sterilization and soil non- sterilization the control effect. In cultivation stage in soil sterilization stage Validamycin (93.3%) showed reliable control effect against the disease. Also, soil non-sterilization stage with low control effect of Validamycin (80%) showed control effect the lower than a soil sterilization stage.

This study shows the differences among residents’ consciousness for general infectious disease and sterilization mediated by vermin. We categorized both industry-related people who work in restaurants, hygiene service shops, whole sales, government organizations, PC shops, factories, department stores and non-industry-related people who work in schools, general offices into two groups for this study. The discovery of vermin held 86% of total exam cases. The vermin included mosquitoes, cockroaches, ants, flies, and so on. People thought these vermin might mediate bacteria infection to human. 80.3% of persons thought mite might exist in blankets, beds and couches. Among 66.6% of total experience of vermin damage, the main damage came from mosquitoes. Frequently used methods of prevention from vermin damage were as follows: "spray of effective chemicals", "install traps" and " report to a prevention company" in order. It indicated that people did not take special actions to repel vermin in spite of their knowing seriousness of damage. Furthermore, just half cases were executed regular sanitization.

This study aimed to investigate and compare the perception of personal protective equipments and instrument sterilization of students who are in attendance at colleges and universities and which have bedside training as a regular subject in their curriculum for third-year students. 'Completely True' is the highest response to the question about the importance of wearing gloves, mask and medical gown from all groups. 'Completely True' is the highest response to the question about the necessity for replacement of gloves from all groups. 'Moderate True' is the highest response to the question about the necessity for replacement of mask from the group without practical training and 'Completely True' is the highest response to the question about the importance of hair cleanliness from all groups regardless of practical training experience. For the question about the perception of instrument disinfection and sterilization, the group with inside and outside practical training showed the highest perception level. Consequently, the right education for prevention of infection by setting inclusive guidelines to enhance the level of perception and practice seems continuously necessary.

Currently, most of the chlorine dioxide gas is processed at the beginning of storage or distribution. It has the disadvantage of not being able to continuously process gas since there is no system that can continuously process it during the distribution process. Therefore, in order to minimize changes in freshness and quality during the distribution process of agrifood, there is a need for a sustained-release chlorine dioxide gas treatment technology that can be continuously released. Therefore, in this study, the film to be used was examined so that the chlorine dioxide gas can be continuously released for a certain period of time, the concentration of the reactant and the viscosity at the time of the reaction were determined, and a chlorine dioxide gas gel pack was manufactured using this optimal condition. In addition, the gel pack was used to measure the amount of chlorine dioxide gas released and the sterilization effect of food poisoning bacteria.

The purpose of this study was to determine the optimum sterilization conditions for the production of retorted steamed egg using response surface methodology. Sterilization processes for eighteen conditions using varying sterilization temperature ($X_1$), time ($X_2$), and method ($X_3$) as the independent variables were carried out through a $3^2{\times}2$ experimental factorial design. Quality evaluations after sterilization included measurements of $F_0$ value ($Y_1$), peak stress ($Y_2$), pH ($Y_3$), color value ($Y_{4-6}$), and organoleptic test [preference for appearance ($Y_7$), overall acceptability ($Y_8$), and preference for texture ($Y_9$) and egg taste ($Y_{10}$)]. Dependent variables ($Y_{1-10}$) of eighteen conditions were more affected by temperature and time than by the sterilization method. Eight factors were selected among the dependent variables as significant factors related to the quality of the steamed egg. Finally, by establishing an optimum range of each dependent variable and contour analysis, the optimum sterilization conditions for the production of steamed egg were determined to be $120^{\circ}C$ for 25 min using a 2-step sterilization process.

A survey on sanitary management at 98 food service institutions located in Jeollabuk-Do were conducted. Food service institutions included 13 hospitals, 38 schools, 40 enterprises, and 7 others. The sterilization in boiling water was used for disinfection of tableware, spoon and chopsticks, and dish towel. Cooking kit, refrigerator, chopping board, and knife were sterilized with disinfectant. Frequency of sanitary training program on employees was 56.1% for 1 time/month, 12.2% for 2-3 times/month, and 11.3% for 1 time/week. Preparing ratio of defrosting, warehouse and rest room, and washing and sterilization diary were 73.8, 60.5, and 54.5%, respectively. However, checking ratio of environments (9.5%), personal sanitation (10.8%), and sanitary training program diary(8.4%) were low. Major obstacle factors on the introduction of Hazard analysis critical control point (HACCP) system into food service institutions were lack of equipment and facilities (54.1%) and lack of understanding and data on HACCP system (17.3%). Therefore, in order to reduce the outbreak of food-borne diseases increasing frequency, we estimated that the introduction of sanitary management system and the conversion of dietician' perception on sanitary managements in food service institutions were needed.
