목 적 : 초등학생을 대상으로 야뇨증의 유병율 및 야뇨증 관련된 역학조사를 위하여 본 연구를 실시하였다. 방 법 : 경기도 수원지역에 있는 두 초등학교(공립 및 사립학교 각 1개교)에 재학 중인 총 1,514명의 학생들을 대상으로 2006년 12월 한 달간 학생부모 설문조사를 통하여 야뇨증과 관련한 역학조사를 실시하였다. 성별, 연령별, 체격지수, 오줌참기 습관, 가정경제수준 등이 야뇨증 유병율에 미치는 영향을 조사하였다. 결 과 : 전체 1,514명의 학생에게 설문하여 1,063명(70.2%)이 응답하였으며, 응답학생 중 93명(8.7%)에게 야뇨증이 있는 것으로 조사되었다. 학교별 유병율을 보면 공립학교 546명 중 48명(8.8%), 사립학교 517명 중 45명(8.7%)에서 야뇨증이 있었다. 공립과 사립 학교간 월 가정수입 차이는 현격하였으나 이에 따른 유병율 차이는 없었다. 야뇨증의 빈도가 남아에서 8.1%, 여아에서 9.6%로 여아에서 더 높은 경향을 보였으나, 통계적으로 유의한 차이는 없었다. 오줌참기 습관이 있는 학생의 경우 22.1 %로 정상인 학생 5.6%에 비하여 유의하게 야뇨증 빈도가 높았다. 신장 및 체중의 백분위 값은 야뇨증이 있는 학생 군이 정상 학생 군에 비하여 작았으나 통계적으로 유의하지는 않았다. 야뇨증이 있는 93명중 25명(26.9%)만이 야뇨증 치료차 병원을 방문한 적이 있음을 볼 때, 야뇨증치료의 필요에 대한 부모의 인식이 매우 낮음을 알 수 있었다. 연령에 따른 야뇨증 유병율을 살펴보면 연령이 증가할수록 연평균 2.0%씩 유병율이 감소하는 것으로 나타났다. 결 론 : 수원지역 2개교 초등학생을 대상으로 한 조사에서 야뇨증의 평균 유병율은 8.7%였으며, 7세 무렵 12.1%에서 매년 2.0%씩 감소하여 13세까지 거의 소실되는 것으로 보였다. 낮 동안에 배뇨억제 습관이나 가뭄뇨가 있는 아동에서 야뇨증 유병율이 높음을 볼 때, 배뇨조절 교육 및 훈련의 확대가 필요한 것으로 판단된다. Purpose : The purpose of this study was to investigate the prevalence of enuresis in association with voiding habits and socioeconomic status in elementary school children. Methods : A dynamic survey was done of 1,514 students from two elementary schools in Suwon, Korea in December 2006. Data regarding gender, age, height and weight, voiding habits, and monthly family incomes were gathered and analyzed to discover any correlation with the incidence of enuresis. The percentile value of height or weight was extrapolated from the standard population curve. Results : Among 1,514 children, 1,063 (70.2%) answered and returned the questionnaires. Overall, the prevalence of enuresis was 8.7% and there was no difference between the public (8.8%) and private school (8.7%). The family incomes of the students from the two schools differed greatly from each other, but there was no difference in the prevalence of enuresis between the two schools. Children with a habit of void-holding showed a higher prevalence of enuresis. No significant correlation was found between the prevalence of enuresis and the height and weight percentile of children. Experience with hospital visits was low among enuretic children (20.8%), suggesting that Korean parents tend to neglect treatment of enuresis for their children. The prevalence of enuresis decreased by 2.0% each year, as school children aged. Conclusion : The overall prevalence of enuresis among elementary school children in Suwon district was 8.7%. The 12.1% prevalence of enuresis at the seven years came down gradually, to be nil at the age of 13. Infrequent urination or void-holding was assumed to be one of the important factors causing enuresis in elementary school children.

This study aimed to investigate the association between interest in beauty care and dietary behaviors of 581 (analysis rate 96.0%) high school girls in Incheon using a survey done in May 2019. Based on the degree of interest in beauty care, subjects were classified as "Beauty care group (n=346)", and "Non-beauty care group (n=235)". The mean age of the subjects was 16.5 years old. The beauty care group had significantly lower BMI than the non-beauty care group (p<0.01). The beauty care group showed a significantly higher interest in weight control than the non-beauty care group (p<0.001). The most time-consuming preschool morning activity in the beauty care group was beauty care, while that of the non-beauty care group was eating breakfast (p<0.001). The beauty care group had significantly higher frequency of exercise than the non-beauty care group (p<0.05). The number of individuals who skipped breakfast was significantly higher in the beauty care group. In addition, the beauty care group had a significantly higher frequency of taking morning snack, convenience food (p<0.01), sweet snacks (p<0.05), and processed beverages (p<0.05) than the non-beauty care group. Our result findings provide important information on the priority groups for nutrition education based on beauty care interest.

We can use document issuance services provided by a school, bank, hospital, company, etc. either by visiting those facilities or by simply visiting their Web sites. Services available through the Internet allow us to use the same services as we do by actually going to those facilities at home or office any time. As much as it saves us time and money, there also arises a problem of information being forged on the Internet or on a printed document. There has to be security functions to deal with the problem. This paper intends to think of the possible security threats and draw out the necessary security functions that an on-line document issuance system should have based on the CC v3.1, so that anyone can use it as reference when they evaluate or introduce the system. 오늘날 우리는 행정기관을 비롯하여 학교, 은행, 병원, 일반 기업 등 다양한 기관에서 해당 기관의 방문 없이 집 사무실 등 어디서든, 24시간 365일 인터넷을 통해 필요한 서류를 발행 받을 수 있는 서비스를 받고 있다. 하지만, 서비스를 제공 및 이용하기 위해서는 인터넷을 통해 전달되는 정보에 대한 위변조 위협 및 출력 문서에 대한 위변조 위협에 대응할 수 있는 보안 기능이 요구된다. 이에 본 논문에서는 온라인상으로 문서를 발급하는 경우 해당 과정 동안에 발생할 수 있는 보안 위협을 도출하고, 이를 통해 온라인증명서 발급시스템이 반드시 갖추어야 할 필수 보안 기능을 공통평가기준 V3.1을 기반으로 도출하고자 한다. 이는 온라인증명서 발급시스템 평가 및 도입 시 참고자료로 충분히 활용될 수 있을 것이다.

이현정,선규근,나경희,박선영,김은영,김경심,김용욱,김석일,Lee, Hyun Jung,Sun, Gyu Geun,Na, Kyung Hee,Park, Sun Young,Kim, Eun Young,Kim, Kyoung Sim,Kim, Yong Wook,Kim, Suk Il 대한소아감염학회 2002 Pediatric Infection and Vaccine Vol.9 No.2

폐흡충증은 비록 발생빈도가 현저히 줄어 현재는 드물게 발생하는 질환이 되었지만 아직도 국내에 폐흡충증과 같은 기생충감염의 보고가 있으므로 게장이나 생가재 등의 섭식을 금하여야 할 것이다. 그리고 호산구 증가증을 동반한 치료되지 않은 폐질환에 있어서 비록 객담이나 대변검사에서 충란이 발견되지 않을지라도 폐흡충증에 대한 정확한 병력청취가 필요하며 폐흡충증은 피내반응검사로 간단히 선별검사를 할 수 있고, 면역효소측정법을 이용하여 비교적 정확하게 진단할 수 있기 때문에 관심을 가지고 적극적인 검사 및 치료가 시행되어야겠다. 폐흡충증이 폐결핵과 임상증상이나 방사선학적으로 여러 가지 유사한 소견을 보인다는 점에서 폐결핵과 감별하는 것은 중요할 것 같다. 본 증례들은 전남 영암 월출산 계곡에서 잡은 생가재를 섭식한 후 일가족에서 발생한 폐흡충증으로서 이제까지 폐흡충증의 발생지역으로 보고된 적이 없었던 월출산 계곡을 새로운 폐흡충증의 발생지역으로 보고하며 지속적인 호산구 증가증을 동반한 치료되지 않은 폐질환이 있을 때 폐흡충증과 같은 기생충감염의 가능성에 대해서도 고려해야 할 것이다. Human infection with the lung fluke Paragonimus westermani has become rare in Korea. Human paragonimiasis is caused by eating raw fresh-water crayfishes or crabs infected with larval metacercariae. Recently, we experienced three cases of pulmonary paragonimiasis in a family. They ate raw fresh-water crayfishes that lived in a stream in Wolchulmountain. All the parients had hypereosinophilia and pulmonary infiltrates with pleural effusion or hydropneumothorax, which did not improve on antibiotics. Ingestion of raw crayfishes was a clue for paragonimiasis. Positive results were shown both on intradermal skin test and ELISA for Paragonimus westermani specific IgG. After treatment with praziquantel, the patients showed an improvement. This is the first familial human paragonimiasis, reported from Wolchulmountain in Chonnam Province where there had been no previous cases of paragonimiasis.

이현정,Lee, Hyun Jung 한국융합학회 2021 한국융합학회논문지 Vol.12 No.10

본 연구에서는 연령집단별로 지역사회 노인의 대면이름대기 능력, 생성이름대기 능력, 청력장애 수준, 우울 수준에 차이가 있는지, 그리고 이들 간에 어떠한 상관관계가 있는지, 마지막으로 지역사회 노인의 두 가지 이름대기 능력(대면이름대기와 생성이름대기)을 설명하는 요인은 무엇인지 알아보고자 하였다. 노인 65명을 65~74세 연소 노인, 75~84세 고령 노인, 85세 이상 초고령 노인으로 구분하였고, 이들을 대상으로 대면이름대기 검사로는 K-BNT-15를, 생성이름대기 검사로는 동물 이름대기 검사를, 주관적 청력장애의 측정은 K-HHIE를, 주관적 우울 정도 측정은 GDS를 사용하였다. 첫째, 연령 집단에 따라 대면이름대기 능력과 우울 수준에서 통계적으로 유의한 차이가 있었다. 둘째, 연령과 우울 수준, 청력장애 수준과 우울 수준 간에 정적 상관을, 교육 수준과 우울 수준 간에는 부적 상관을 보였다. 셋째, 대면이름대기 점수는 연령이, 생성이름대기 점수는 우울 수준이 설명하는 것으로 나타났다. 본 연구의 결과는 노년층의 이름대기 능력, 청력장애 정도, 우울 수준을 연령대별로 세분화하여 살펴보고, 이들이 단순히 노화의 결과가 아니라는 것과, 이를 해결하기 위해서는 다양한 분야에서 보다 융합적인 접근이 필요함을 보여주었다. The purpose of the study was to investigate whether there are differences in confrontation naming ability, generative naming ability, hearing handicap, and depression in community-dwelling elderly by age group, and whether there is any correlation among them, and to find out what factors explain the two naming abilities (confront and generative) of the elderly. Sixty-five community-dwelling elderly people participated: 65~74 years were classified into young-old; 75~84 years into old-old; and 85 years and over into oldest-old. K-BNT-15 for the confrontation naming ability, animal naming test for the generative naming ability, K-HHIE for the subjective hearing handicap, and GDS for the subjective depression were administered. First, there was a statistically significant difference in confrontation naming and depression levels according to age groups. Second, there was a positive correlation between chronological age and subjective depression level and between subjective hearing handicap level and subjective depression level, and a negative correlation between education level and subjective depression level. Third, the confrontation naming score was explained by age, and the generative naming score was explained by subjective depression level. The results show that naming abilities, subjective hearing handicap, and subjective depression level are not simply the result of normal aging and that a convergence approach is needed in various fields to solve the issue.

This was a systemized bed consisted of storage units, a desk, a drawer, a sofa and a shelf. This bed system was not designed only for a certain age group of children but also for various age groups of children, since each parts of the bed can be sued separately. Separation of parts of the bed allowed children to decorate their own living space and gives them a chance to express their own feeling and thoughts by layout of parts. Design adopts the beauty of nature such as smoothly curve lines which are perfectly fit for the children's living space. The moving sofa located under the bed and the book shelf lead children to establish a pattern of reading habit. The draw and storage units offer nice space for keeping children's goods.

Handles are very essential element to satisfy function of furniture except for furniture without doors. Moreover, handles of furniture tend to have not only functions for opening and shutting but also decorations for furniture. Among various hardware for furniture, handles are the one who influence furniture's design most. Yet, cases of damages occur due to the fact that there are many copying. Handles have short lives, so that it is economically quiet burden to develop new products in Korea. Therefore, this study aims to inspire necessity of investment for handles and other hardware's development by classifying types of handles, systemizing basic knowledge of design for furniture handles, and realizing the importance of handles within domestic demand.

Objective: To evaluate whether co-culture of oocytes on vero cell monolayers from Day 0 (Day 0 group) after egg retrieval results in an increase in developmental capacity such as fertilization rate, embryo quality, blastulation and clinical pregnancy rate compared with co-culture of oocytes from Day 1 (Day 1 group). Methods: Sperms were treated with Hams F-10 supplemented with 10% human follicular fluid (hFF). Vero cells for co-culture were prepared in TCM-199 with 10% FBS. Oocytes were co-cultured from Day 0 and fertilized oocytes were co-cultured from Day 1 on vero cell monolayers in DMEM with 10% and 20% hFF, respectively after egg retrieval. On day 1, 2 and 5, fertilization rate and grade of embryos and blastocysts were evaluated. Results (fertilization rate, cleavage rate, grade of embryos and blastocysts and pregnancy rate) were considered statistically significant when p value was less than 0.05 using t-test and $x^2$. Results: In sibling oocytes of same cycles, no differences were found in fertilization rate (94.6 vs. 91.4%), cleavage rates (94.6 vs. 91.4%), embryo grade (on day 2 and 3) and blastulation (65.6 vs. 57.0%) and their grade. In different oocytes of different cycles (patients), no differences were found in fertilization (79.8 vs. 78.3%), cleavage rates (77.7 vs. 76.4%) and blastulation (56.0 vs. 45.3%), but pregnancy rate was higher in the Day 0 group than in the Day 1 group (60.0 vs. 42.9%). Conclusions: This study revealed that the embryonic development capacities were not affected by the different co-culture time in the sibling oocytes of same cycles. Although no statistical significance, because of small size of study, there was a trend for higher pregnancy rates in Day 0 group compared to Day 1 group in different oocytes of different cycles.

Purpose: This study was conducted to analyze the factors associated with intoxicated patient's disposition in the pediatric emergency department. Methods: We retrospectively evaluated pediatric intoxicated patients visiting the pediatric emergency department of a hospital between January 1, 2011 and December 31, 2013. Specifically, we analyzed the association between hospitalization recommended rate and the following variables: patient age group, symptoms, intentional poisoning, decontamination and toxic level of substance. Results: We collected data from 345 patients. A high incidence was noted in the 1-4 years of age group and 10-15 years of age group. Unintentional poisoning occurred in 306 patients (88.7%). A total of 115 patients (33.3%) had symptoms when visiting. Forty three patients (12.5%) ingested cleaning substances, which was the most common agent. Potentially-toxic level was the most common level of the substance. The hospitalization recommended rate associated with visits in 2011 was 2.5 times greater than in 2012 and 2013, decontamination was 2.0 times greater than no decontamination, and poisoning with potentially-toxic substances was 2.6 times greater than poisoning with other toxic substances. Additionally, the hospitalization recommended rate associated with symptomatic patients was 2.4 times greater than that of asymptomatic patients and intentional poisoning was 2.4 times greater than unintentional poisoning. Conclusion: Patients with decontamination, ingestion of potentially-toxic substances, symptoms and intentional poisoning had increased hospitalization rates. In addition, the hospitalization rate for patients who visited in 2011 was greater than that of patients who visited in 2012 or 2013.
