Uiseong-gun, Gyeongsangbuk-do, one of the representative small rain regions, has developed a traditional irrigation farming system while overcoming and adapting to unfavorable agricultural environments from the days of the ancient nation of Jomunguk to the present. In 2018, its value was recognized and designated as Nationally Important Agricultural Heritage System No. 10. This study was conducted with the purpose of examining the characteristics of the traditional irrigation farming system in Uiseong from the viewpoints of irrigation facilities, irrigation communities, and agricultural activities. The research results are as follows. Uiseong-gun has been expanding irrigation facilities for agriculture since long ago, and it has been investigated that a total of 6,227 irrigation facilities are currently distributed along the Wicheon water system that crosses Uiseong-gun from east to west. Irrigation facilities appear differently depending on the topography. The irrigation facility has a 'su-tong' as an irrigation passage and a corkscrew structure 'mot-tchong' as a water quantity control device, so the amount of water was adjusted as needed. Through this facility, surface water with warmer temperature is supplied to the farmland to prevent cold damage to crops. Uiseong has developed activities to organize irrigation communities in one village or several villages to secure agricultural water from an early age. Currently, this tradition continues, and a total of 213 irrigation communities manage 375 irrigation facilities (6.0% of all irrigation facilities). Through this organization, called Mong-ri-gye, water for agriculture is obtained, managed, and distributed equitably. In order to increase agricultural production, Uiseong implemented double cropping by converting rice fields and fields. In the case of Mt. Geumseong, double cropping of rice and barley was mainly carried out until the 1970s, but since the 1980s, double cropping of rice and garlic has been implemented with higher income. One of the unique features of the agricultural system of this region is the spectacular landscape that changes simultaneously from field to rice field in spring and from rice field to field in autumn.

The purpose of this study is to investigate about security service history during the 1st and 2nd Republic. The 3rd Republic, one of the important periods, deserves special emphasis until now. But Compared with 1st and 2nd Republic, the 3rd Republic is inferior. Although security service history excluded the 1st and 2nd Republic. This research focused on the two points about the chief of the presidential security and the law of presidential security special order. Firstly, the chiefs of the presidential security in 1st Republic were Kim, Jang-Heung Seo, Jung-Hak Kim, Kuk-Jin Kwak, Young-Joo. Secondly, The law of presidential security special order be specified in Korean presidential security for the first time. Before the 1st Republic already recognized the importance of security services when they adopted the first security service regulations on December 29, 1949, which comprised 25 articles. But this law was only focused on presidential security and promulgated the law more than 10 years ago than law of the office of the Presidential Security in 1963. Deplorable in this law was declared by statute on July 7, 1953 from the 1st Republic, but repealed in 1960 after the 2nd Republic. Thirdly, 2nd Republic established the presidential security organization with the new government has been formed. In spite of this organization can not be kept for a long time, 2nd Republic attempted to professional forms of presidential security organization. The research of secret service history must continue to advance for academical learning.

Background : Diffuse panbronchiolitis(DPB) is a chronic inflammatory lung disease of unknown etiology which has characteristic clinical, radiological and pathological features, and is distinguished from bronchial asthma, chronic bronchitis, pulmonary emphysema, bronchiectasis, or alveolitis. Clinically, patients with DPB have chronic cough, purulent sputum, exertional dyspnea, and finally respiratory failure. Until a few years ago, the prognosis of DPB had been thought to be very grave, because there had been no effective treatment for the disease. But recent1y, low-dose long-term erythromycin was found to be very effective on DPB. Even though DPB is prevalent in Japan, and is known to be rare outside of Japan, we have a1ready reported the clinical features of 16 DPB cases in Korea. We tried low-dose long-term erythromycin on DPB patients and analyzed the clinical effect of erythromycin. Methods : We analyzed the changes of subjective symptoms, physical signs, pulmonary function tests and chest X-rays on 14 DPB patients with more than 6 months erythromycin treatment during the period from September 1989 to August 1992 in Seoul National University Hospital. Results : 1) Subjective symptoms improved in all patients within 2-3 months, and 54.5% of the patients showed no symptom after one year of treatment. 2) Crackles and wheezing decreased in 92.9% of the patients after 3 months and completely disapppeared in 63.5% of the patients after one year of treatment. 3) FVC and FEV1 increased remarkably during the first 3 months, and slowly increased thereafter, reaching normal level after one year of treatment. 4) Small nodular lesions on chest X-ray decreased in all patients, and chest PA was normal in 36.4% of the patients after one year of treatment. 5) There was side effect in one patient, stopping medication because of dyspepsia. One patient stopped medication because of no symptom after 16 months of treatment, but her symptom recurring after one month, improving again after retreatment. Conclusion: Low-dose long-term erythromycin showed ramarkable effectiveness on DPB. Further studies are needed on the mechanism of the drug and the duration of the treatment.

Successful results of treatments using double crown prostheses for the partially edentulous patients who have a few remaining teeth have been reported in several journals. A double crown removable partial denture can be an alternative treatment for the patients with a poor periodontal condition of remaining teeth. Since a double crown removable partial denture can be applied without the risk of surgical operation to the medically compromised patients with a poor periodontal condition which is inadequate for dental implants, it has psychological and economical advantages. In this case, there were sufficient remaining teeth to be restored with fixed prostheses in maxilla, while there were a few remaining teeth with a very poor periodontal condition so that it was almost impossible to restore with a clasp removable partial denture using these remaining teeth in mandible. In addition, the patient had the medical history of surgical operation due to osteomyelitis in the mandibular anterior areas a year ago, thus difficult to conduct an implant placement. The main objective of this report is to introduce our case because a double crown partial denture using a few mandibular remaining teeth showed satisfactory results in functional and esthetical aspects during more than two years follow-up period in this unfavorable condition.

This paper aims to analyze the rise and decline of Seattle Community Network(briefly SCN), an electronic community network based upon Seattle, U.S. from the perspective of 'social shaping of technology' theory rather than that of technological determinism That is, this paper focuses on the social processes of the evolution of SCN. And this paper considers SCN as one important element of the 'network society', a concept manufactured by Manuel Castells. SCN was built successfully over 10 years ago by some progressive local activists and volunteers. The main purpose of building SCN at that time was said to make local community stronger with the help of advanced information technology. This can be understood that the founders of SCN tried to shape the direction of network society development based on civil society's values including public access and commitment to democracy rather than those of private companies. After some years of successful working, however, SCN started to decline. The expansion of internet services and the booming of dot.com companies in the late 90's were the main factors that made SCN decline. In conclusion, it can be said that the socia-economic factors rather than technological factors gave birth to the rise and decline of SCN.

Two years ago, a 75-year-old female was diagnosed left renal cancer and went on radical nephrectomy. Recently, metastatized lesions on lumbar spine and various lymph nodes including paraaortic lymph node of which diameter was about 5.5 cm was identified. She suffered from extreme low back pain despite using opioid agents of fentanyl patch and oral oxycodone. During about one month, Korean medicine therpies including herbal medicine(Yang-He tang), acupuncture with her conventional medications were co-administered. However her pain didn't improved and gradual cough and dyspnea developed. So she transferred to the hemato-oncology part for 2 weeks under the diagnosis of everolimus-induced noninfectious pneumonitis. After quitting everolimus her pneumonitis was improved and she came back our ward and started another herbal medicine, Ai-Tong-Ning tang for about 2 months. During this period, her pain was well managed without oral opioid agents and her paraaortic lymph node was regressed to about 2.2cm in diameter.

Purpose : Fever, the most common presenting symptom in pediatric clinics, has been believed to be a dangerous symptom by many parents. Proper recognition about fever will relieve unnecessary anxiety of parents and help them understand the course of the disease. Our objectives of this study were to investigate current parental recognition about fever and to compare these results with those described in 1992. Methods : Between May and July 2006, we questioned caregivers who visited the pediatric outpatient clinic in St.Paul hospital. The questionnaire consisted of 19 items asking about recognition, attitude and management of fever. Results : A total of 136 caregivers were interviewed. Compared with 10 years ago, there were no significant improvements in misconception about fever. Many caregivers (61%) had wrong information about a definition and the way to measure body temperature. There were still high concerns about febrile convulsion and brain damage from fever. Caregivers started treatment at the body temperature which actually needed no therapy. Conclusion : Parents were not aware that fever is just one of physiologic responses and has benefits, which led to unnecessary anxiety and treatment. This misconception has not been changed over the years. Pediatrician should inform parents that fever itself is not harmful and only rational reason for use of antipyretics is to relieve a discomfort of a febrile child. An educational interventions offered by pediatricians will be helpful for parents to have right attitude and understandings toward fever.

This study was conducted to find out about the implementation status of dental treatment infection control standards of dental hygienists. The subjects of research were the dental hygienists working at dentist offices in Chungnam, Cheonan-si using self-input method from July 25th, 2012 to August 1st 2012. The collected data was analyzed after computerized statistical processing using SPSS 18.0. For hepatitis B vaccination, the results were high with 75.0% of answers being 'yes' or auto-active immunity, but for the latest hepatitis vaccination period showed highest results in '5 years or more ago' with 48.0%. Although 93.0% answered that vaccination was important, the percentage of replies that they had vaccination education was relatively low with 41.0%. For the use of personal protection tools the use of protective goggles was low compared to the use of masks and medical gloves. The percentage of subjects that answered that they always wash their hands before treatment was relatively low with 56.0% compared to 82.0% of subjects that answered that they always washed their hands after treatment. Dental treatment equipment washing before sterilization, use of packing and re-sterilization of tools with damaged packing showed high results for 'yes', but the ratio of subjects that answered 'no' to water line management was low with 39%.

Opisthorchis viverrini is remains a public health problem in Thailand, particularly in the northeast and north regions which have the highest incidences of chonalgiocarcinoma (CCA). O. viverrini causes the disease opithorchiasis, and its has been classified as a group 1 biological carcinogen. Humans, dogs, and cats become infected with O. viverrini by ingesting raw or undercooked fish containing infective metacercariae. The first human cases of O. viverrini infection were reported in Thailand 100 years ago, and it's still a problem at the community level. Based on data for the year 2009, more than 6 million people were infected with O. viverrini. Associated medical care and loss of wages in Thailand costs about $120 million annually. This review highlights the current status of O. viverrini infection in communities of Thailand through active surveillance for the five years period from 2010 and 2015. A total of 17 community-based surveys were conducted, most in the northeast region. Some 7 surveys demonstrated a high prevalence over 20%, and the highest was 45.7%. Most commonly infection was found in age group of 35 years and older, males, and agricultural workers. Although, the national prevalence may be decreasing but the results show that the O. viverrini infection is still high in communities of the northeast region. Therefore, the focus in populations living in northeast Thailand should be screening of infection and changing their eating behavior.

It is not long since treatment of food waste became a social problem. However, it is a fact that there have been a lot of debates on the treatment of food waste since several years ago. At present, two ways of disposing food waste are under great interest in Korea and Japan. One is drying of food waste at high temperature. The other is disappearance type, in which analysis by microorganism takes place with continuous supply of a bulking agent for a certain period of time that was stored in a reactor. In our laboratory, Disappearance type Food Waste Disposer is under interest, and experiments regarding condition establishment for efficient analysis of food waste were conducted. As preceding experimentation, experiments were done with regard to the selection of a substance to be used as a bulking agent, improvement by addition of a substance which maximizes initial growth of microorganism, and a concentration change in rank odors generated by reaction with deodorizer (absorbent). The results turned out to be satisfactory.
