The present study was designed to elucidate the recent prevalence of the intestinal protozoa and to demonstrate the relationship on prevalence of the surveyed population with their academic career and living conditions. During the period from May to July 1981, total 2, 735 fecal specimens were collected from the inhabitants of 11 areas in Gyeong-gi Do(province) near by Seoul City, and 6 areas in Jeonra Bug Do, southwestern part of Korea. The samples were fixed with SAF solution and were examined by formalin-ether sedimentation technique. The results are summarised as follows: 1, Overall positive rate of intestinal protozoa was 11. l% : Gyeong-gi Do, 10.7%; Jeonra Bug Do, 11.7%. 2. Five species of intestinal protozoa were detected: Entamoeba histolytica 0.69% : Entamoeba cali 5.52%; Endolimax nana 2.71%, Giardia lamblia 2.23%; lodamoeba biitschlii 0.18%. 3. Highest positive rates among the examined areas were recognized: Incheon City of Gyeong-gi Do, 26.7%; Im-sil Gun(county) of Jeonra Bug Do, 19.9%. 4. By species, E. nana showed the highest prevalence rate (13.74%) in Incheon City, and E. histolytica (2.37%) and E. coli (9.95%) in Im-sil Gun. 5. Prevalence of E. histolytica in rural areas was higher than in urban areas. 6. No significant difference in the prevalence rate by sect and age was recognized, although the group under 10 years and over 60 years were lower than in other age groups. 7, The highest positive rate of E. histolytica was observed in pauper group and significant linearity of prevalence rate of E. histozytica by monthly income was observed. 8. The inhabitants who used conventional latrine showed higher prevalence, 11.5%, than the group of inhabitants who used modified privy. 9. Although no significant difference of positive rate was recognized by academic career, but the lowest prevalence rate was observed in college graduates. 10. Over half of the surveyed population, 64.8% has no experience on anthelmintic practice. Number of anthelmintic application resulted no difference in prevalence. In conclusion, prevalences of intestinal protozoa in Gyeong-gi Do and Jeonra Bug Do decreased remarkably in comparison with those of one decade before. However, economic level, academic career and anthelmintic administration seemed no essential reasons for such declination.

Since 1990, South Korean children living in relative poverty have increased whereas those living in absolute poverty have decreased until 2002 and then the decrease remained somewhat stagnant. A substantial body of research proposed a strong relations between child poverty and low quality well-being of the child. Poor children, in comparison to those of more affluent families, are more likely to have health, behavioral, social, and emotional problems. They are also more likely to grow up in families that provide less cognitive stimulations which, in turn, can negatively affect their cognitive and academic attainments. The present paper highlights the trends and the consequences of child poverty and suggests policy approaches based on the premise of decreasing poverty of low-income children and their families.

The purpose of our study is to analyze the effect of socio-economic status on the diet pattern of Korean adults. Raw data from the fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) were used, and finally 11,700 adults were analyzed as subjects. Results in consideration of the socio-economic status of the subjects, a linear trend was observed in men in which the odds ratio of having lunch (p for trend=0.006) and dinner (p for trend=0.0317) decreased as the level of education went down. In diet frequency, a decreasing trend (p for trend=0.0328) was observed in which the odds ratio of having 3 meals a day reduced as the household income lowered. For women, a linear trend (p for trend=0.0012) was observed in which the frequency of dinner decreased as the level of education became lower. A falling trend in the rate of having 3 meals a day was also observed (p for trend=0.0135). Our study analyzed the characteristics of the diet patterns of individuals according to their socio-economic status with the purpose of suggesting guidelines for correcting. To prevent this, we will need education and awareness and public attention for the practice of correct eating habits.

The incidence of cervical cancer has been gradually decreased since 1990, now it ranks the fourth most common carcinoma among Korean women in 2001. If squamous cell carcinomas in situ are included, the cervical cancer is still the most frequent tumor in Korean women. However, cervical cancer mortality in Korea has been decreased over the last 10 years in large part attributable to the introduction of the Papanicolaou test (Pap. test). The guidelines for the early detection of cervical cancer recommend women aged 30 and more to lake biennial screening with Pap. lest. According to the screening data of National Health Insurance Corporation (NHIC), 4,425 women (0.94%) showed an abnormal Pap among 473,395 cases tested in 2001; dysplasia was in 3,953 (0.84%) women, in situ carcinoma in 357 (0.075%) women, and invasive carcinoma in 115 (0.024%) women. The detection rates of abnormal Pap. were 4.21% in Korean Society for Cytopathology(KSC-2001), 1.37% (ASCUS : 0.26%, AGUS : 0.03%, LSIL : 0.45%, HSIL : 0.55%, Carcinoma 0.09%) in health check-up and 5.41% (ASCUS : 1.89%, AGUS . : 0.69%, LSIL : 1.39%, HSIL : 0.84%, Carcinoma : 0.64%) of patients in out-patient clinic without having history of cervical neoplasia at Hanyang University Hospital in 2002 Low rate of cervical cancer screening (34%) in Korea is mainly due to the lack of information for the Row income people regarding national cancer screening program. More adenuate budget by government and more man-power for precise screening, new guideline and system for management of the cervical cancer patients are required.

Due to urbanization and industrialization, the population of rural areas has sharply decreased, and the social phenomena of low fertility and aging have occurred due to many factors such as the spread of individualism and single-person households derived from urbanization and economic growth. In order to cope with the low birth rate and the aged society, the Korean government has invested 152.1 trillion won from 2006 to 2015 and to proceeded total 231 projects in 3 different areas including the low fertility(95 projects), the aged society(78 projects), and the growth momentum(58 projects). Among the social problems caused by the low birth rate and the aged society, there have been not enough studies on the closed schools which will result from the social phenomenon of decreases in the school age population. The purpose of this study is to analyze the current extent of utilizing closed schools in Korea, to derive some types based on the analysis, and to provide basic data on the use of closed schools in Korea in the future. The types of closed schools can be classified into education facilities, social welfare facilities, cultural facilities, public sports facilities, income growing facilities, and others. Based on the classification, the analyses of the characteristics of each type for the facilities are presented.

It seems high time to increase productivity by adopting e-business to overcome challenges posed by both external factors including the appreciation of Korean won, oil hikes and fierce global competition and domestic issues represented by disparities between large corporations and small and medium enterprises (SMEs), Seoul metropolitan and local cities, and export and domestic demand all of which weaken future growth engines in the Korean economy. The demands of the globalization era are for innovative changes in businessprocess and industrial structure aiming for creating new values. To this end, e-business is expected to play a core role in the sophistication of the Korean economy through new values and innovation. In order to examine business performance in e-business-adopting industries, this study analyzed the home shopping industry by closely looking into the financial ratios including the ratio of net profit to sales, the ratio of operation income to sales, the ratio of gross cost to sales cost, the ratio of gross cost to selling, general and administrative (SG&A) expense, and return of investment (ROI). This study, for best outcome, referred to corporate financial statements as a main resource to calculate financial ratios by utilizing Data Analysis, Retrieval and Transfer System (DART) of the Financial Supervisory Service, one of the Korea's financial supervisory authorities. First of all, the result of the trend analysis on the ratio of net profit to sales is as following. CJ Home Shopping has registered a remarkable increase in its ratio of net profit rate to sales since 2002 while its competitors find it hard to catch up with CJ's stunning performances. This is partly due to the efficient management compared to CJ's value of capital. Such significance, if the current trend continues, will make the front-runner assume the largest market share. On the other hand, GS Home Shopping, despite its best organized system and largest value of capital among others, lacks efficiency in management. Second of all, the result of the trend analysis on the ratio of operation income to sales is as following. Both CJ Home Shopping and GS Home Shopping have, until 2004, recorded similar growth trend. However, while CJ Home Shopping's operating income continued to increase in 2005, GS Home Shopping observed its operating income declining which resulted in the increasing income gap with CJ Home Shopping. While CJ Home Shopping with the largest market share in home shopping industryis engaged in aggressive marketing, GS Home Shopping due to its stability-driven management strategies falls behind CJ again in the ratio of operation income to sales in spite of its favorable management environment including its large capital. Companies in the Group B were established in the same year of 2001. NS Home Shopping was the first in the Group B to shift its loss to profit. Woori Home Shopping has continued to post operating loss for three consecutive years and finally was sold to Lotte Group in 2007, but since then, has registered a continuing increase in net income on sales. Third of all, the result of the trend analysis on the ratio of gross cost to sales cost is as following. Since home shopping falls into sales business, its cost of sales is much lower than that of other types of business such as manufacturing industry. Since 2002 in gross costs including cost of sales, SG&A expense, and non-operating expense, cost of sales turned out to have remarkably decreased. Group B has also posted a notable decline in the same sector since 2002. Fourth of all, the result of the trend analysis on the ratio of gross cost to SG&A expense is as following. Due to its unique characteristics, the home shopping industry usually posts ahigh ratio of SG&A expense. However, more than 80% of SG&A expense means the result of lax management and at the same time, a sharp lower net income on sales than other industries. Last but not least, the result of the trend analysis on ROI is as following. As for CJ Home Shopping, the curve of ROI looks similar to that of its investment on fixed assets. As it turned out, the company's ratio of fixed assets to operating income skyrocketed in 2004 and 2005. As far as GS Home Shopping is concerned, its fixed assets are not as much as that of CJ Home Shopping. Consequently, competition in the home shopping industry, at the moment, is among CJ, GS, Hyundai, NS and Woori Home Shoppings, and all of them need to more thoroughly manage their costs. In order for the late-comers of Group B and other home shopping companies to advance further, the current lax management should be reformed particularly on their SG&A expense sector. Provided that the total sales volume in the Internet shopping sector is projected to grow over 20 trillion won by the year 2010, it is concluded that all the participants in the home shopping industry should put strategies on efficient management on costs and expenses as their top priority rather than increase revenues, if they hope to grow even further after 2007.

본 연구에서는 임대주택에 대한 수요가 많은 서울을 중심으로, 최저소득계층을 대상으로 하는 매입임대주택의 공급 현황과 문제점을 구체적으로 파악함으로써 이에 대한 개선 방안을 제시하고자 한다. 주거비 부담 문제의 심화로 매입임대주택의 공급 확대가 필요함에도 불구하고, LH공사와 SH공사에 의해 서울에 공급되는 신규 매입임대주택 호수는 2009년 이후 감소 추세를 보이고 있다. 매입임대주택은 지역 거주민을 입주 대상으로 하기 때문에, 지역별 공급 규모가 주거복지 수혜의 형평성 문제를 야기하게 되는데, 전반적으로 저소득층이 많이 거주하는 도심에 공급이 적고, 서울 외곽의 특정구에 공급이 편중되어 있다. 이와 같은 신규 공급 정체와 지역 편중 문제의 원인은 정부의 낮은 지원 기준단가로 인해 재원 구조가 취약하기 때문이다. 따라서 실거래가 기준으로 정부 기준단가를 인상하고, 실거래가 변동률과 정부 기준단가를 연계하는 것이 필요하다. 수요에 기반한 공급물량 배분을 위한 종합계획이 수립되어야 하며, 매입임대주택을 비롯한 저렴임대주택 공급이 많은 지역들에서는 차상위계층 및 저소득 청년으로 입주 대상이 확대되어야 한다.
