<P><B>Purpose</B></P><P>This study was aimed to investigate the relationship between indoor air pollutant levels and residential environment in children with atopic dermatitis (AD) living in Seoul.</P><P><B>Methods</B></P><P>A total of 150 children with AD were included. Residential environment was assessed by questionnaires which were completed by their parents. To evaluate the level of exposure to the indoor air pollutants, concentrations of the indoor air pollutants including particulate matter with diameter less than 10 µm (PM<SUB>10</SUB>), formaldehyde, carbon dioxide (CO<SUB>2</SUB>), carbon monoxide (CO), nitrogen dioxide (NO<SUB>2</SUB>), Total Volatile Organic Compound (TVOC), benzene, toluene, ethyl-benzene, xylene, styrene, bacterial aerosols, and airborne fungi were measured.</P><P><B>Results</B></P><P>A significant difference was exhibited in the levels of PM<SUB>10</SUB> in case of visible fungus on the walls (<I>P</I>=0.047). There was relationship between the construction year of the house, moving to a newly constructed building within 1 year and formaldehyde level. With the use of artificial air freshener, the differences were found in the concentrations of TVOC (<I>P</I>=0.003), benzene (<I>P</I>=0.015), toluene (<I>P</I>=0.012) and ethyl-benzene (<I>P</I>=0.027). The concentration of xylene was significantly high when oil was used as heating fuel (<I>P</I>=0.015). Styrene exhibited differences depending on building type and its concentrations were significantly high in a residential and commercial complex building (<I>P</I>=0.005). The indoor concentration of bacterial aerosols was significantly low with the use of air cleaner (<I>P</I>=0.045). High NO<SUB>2</SUB>, benzene concentrations were present in case of almost no ventilation (<I>P</I>=0.028 and <I>P</I>=0.028, respectively).</P><P><B>Conclusions</B></P><P>Individual residential environments are closely related with the levels of the indoor air pollutants. To alleviate AD symptoms, simple questions about residential environments such as visible fungus on the walls and the use of artificial air freshener are helpful to assess the possibility of increased indoor air pollutant levels when direct measurement is not available.</P>

Arthroscopic Resection of a Tenosynovial Giant Cell Tumor in the Wrist : A Case Report

Lee, Young-Keun,Han, Youngshin,Lee, Malrey Williams & Wilkins Co 2015 Medicine Vol.94 No.42

<P><B>Abstract</B></P><P>The treatment for giant cell tumors of the tendon sheath is surgical therapy, but surgical recurrence rates were reported to be as high as 50% in some cases. Therefore, complete radical excision of the lesion is the treatment of choice. If the tumor originates from the joint, it is important to perform capsulotomy. Here, the authors report the first case of successful treatment of a localized intra-articular giant cell tumor in the wrist by arthroscopic resection.</P><P>A 28-year-old right-handed woman visited the clinic because of left wrist ulnar-side pain, which had been aggravated during the previous 15 days. Vague ulnar-side wrist pain had begun 2 years ago. When the authors examined the patient, the wrist showed mild swelling on the volo-ulnar aspect and the distal radioulnar joint, as well as volar joint line tenderness. She showed a positive result on the ulnocarpal stress test and displayed limited range of motion. Magnetic resonance imaging revealed an intra-articular mass with synovitis in the ulnocarpal joint. Wrist arthroscopy was performed using standard portals under regional anesthesia. The arthroscopic findings revealed a large, well-encapsulated, yellow lobulated soft-tissue mass that was attached to the volar side of the ulnocarpal ligament and connected to the extra-articular side. The mass was completely excised piece by piece with a grasping forceps. Histopathologic examination revealed that the lesion was an intra-articular localized form of a tenosynovial giant cell tumor.</P><P>At 24-month follow-up, the patient was completely asymptomatic and had full range of motion in her left wrist, and no recurrence was found in magnetic resonance imaging follow-up evaluations.</P><P>The authors suggest that the arthroscopic excision of intra-articular giant cell tumors, as in this case, may be an alternative method to open excisions, with many advantages.</P>

이 연구에서는 부모자녀관계와 자기효능감이 청소년의 학업성취와 효도에 미치는 영향을 분석하는데 주된 목적이 있다. 이를 위해 부모자녀관계는 부모 희생, 부모 존경, 부모에 대한 죄송함을 하위변인으로 하였으며, 자기효능감은 부모관계효능감, 자기조절학습효능감, 어려움극복효능감을 하위변인으로 포함하여 경로분석을 하였다. 분석 대상은 중학교 1학년 298명(남 169, 여 129)이었으며, 측정도구의 신뢰도는 α=.78∼.90이었다. 분석 결과, 첫째, 부모자녀관계(희생, 존경, 죄송함)는 자기효능감에 대해 정적인 영향이 있었는데, 특히 부모에 대한 존경심이 높을수록 청소년의 자기효능감이 높았다. 둘째, 자기효능감(부모관계효능감, 자기조절학습효능감, 어려움극복효능감)은 학업성취에 정적인 영향이 있었는데, 특히 자기조절학습효능감이 높은 청소년일수록 높은 학업성취도를 나타내었다. 셋째, 자기효능감은 효도에 정적인 영향이 있었는데, 특히 부모관계효능감이 높은 청소년일수록 부모에게 효도하였다. 넷째, 부모자녀관계는 자기효능감을 매개변인으로 하여 학업성취와 효도에 대해 간접효과가 있었는데, 특히 부모에 대한 존경심이 높은 청소년이 부모관계효능감을 매개로 하여 학업성취가 증진되고 부모에 대한 효도를 많이 하였다. 다섯째, 청소년의 학업성취와 효도는 정적인 관계를 나타내었다. The main purpose of this study is to examine the effects of parent-child relationship and self-efficacy on adolescent academic achievement and filial piety. This is end, various path analyses were conducted while rotating the parent-child relationship variables (conceptualized as parental sacrifice, respect towards parents and indebtedness towards parents), and self-efficacy variables (conceptualized as adolescent``s relational efficacy towards their parents, self-efficacy for self-regulated learning, and resiliency of self-efficacy). The participants in this study were 298 Korean middle school students (169 males, 129 females). The questionnaires displayed Cronbach alpha coefficients ranging from 0.78 to 0.90. The results showed a significant positive path coefficient of parent-child relationship (sacrifice, respect, and indebtedness) on self-efficacy, the direct effect was especially stronger with regards to the influence of respect for parents on adolescent self-efficacy, that is the higher the level of respect for parents the greater the adolescent self-efficacy. Second, the results showed a significant and positive path coefficient of self-efficacy (relational efficacy, self-efficacy for self-regulated learning, and resiliency of self-efficacy) on academic achievement, the direct effect was especially stronger with regards to the influence of self-efficacy for self-regulated learning on academic achievement, that is the higher level of self efficacy for self-regulated learning the higher the academic achievement. Third, the results also showed a significant and positive path coefficient of self-efficacy on filial piety, the direct effect was especially stronger with regards to the influence of adolescent``s relational efficacy towards their parents on filial piety, that is the higher level of relational efficacy towards their parents resulted in greater displays of filial piety. Fourth, indirect effects were seen for parent-child relationship upon academic achievement and filial piety, with the effects stronger for respect for parents and relational efficacy towards their parents, that is the higher the level of respect for their parents the higher the mediating effects of relational efficacy towards their parents, resulting in greater academic achievements and display of filial piety. Fifth, significant positive correlation was found between academic achievement and filial piety.

이영신(Youngshin Lee),신상희(Sanghee Shin),이태호(Taeho Lee) 한국지반환경공학회 2014 한국지반환경공학회논문집 Vol.15 No.4

본 연구의 목적은 삽교호 지역을 대상으로 오염물질에 따른 구역별 유달률을 산정하고 오염물질 부하량에 따른 유달특성을 조사하고자 한다. 삽교호 주변의 주요하천은 남원천, 도고천, 삽교천, 무한천, 곡교천이고 5개 주요하천의 강우 시 유달률과 그 특성을 조사되었다. 그 결과 삽교호 조사 유역 전체의 유달률 BOD는 0.40, 총질소(T-N)는 0.34, 총인(T-P)은 0.08이었고 T-P의 유달률은 다른 수질항목에 비교해서 상대적으로 낮게 조사되었다. 또한 유역 전반의 특성을 살펴보면 T-N과 T-P의 유달률은 연중 변화가 거의 없었다. T-N의 유달률은 갈수기 때에 0.2∼0.3이었고 홍수기 때에는 0.31∼0.39였다. T-P의 유달률은 갈수기에 0.3 이상, 홍수기 때에 0.11의 값을 나타내는데 이는 연평균 유달률인 0.08과 비슷한 값이다. 본 조사에서 계측한 각각의 유달률은 토지이용과 지형 특성이 유사한 지역의 유달률처럼 적용이 가능할 것이다. The purpose of this study investigates the delivery characteristics according to the load of pollutants by calculating the delivery rate of targeted areas on pollutants in Sapkyo reservoir. The main rivers of Sapkyo reservoir are Namwoncheon, Dogocheon, Sapkyocheon, Muhancheon and Gokgyocheon. The delivery rate and their characteristics of five major rivers during rainfall season are investigated. As th result, biochemical oxygen demand (BOD), total nitrogen (T-N) and total phosphorous (T-P) of total delivery rate are calculated by 0.40, 0.34 and 0.08, respectively. The delivery rate of T-P compares to other water quality is investigated relatively low. Looked at the overall characteristics of the watershed, the delivery rate of T-N and T-P is little change in the rate of the year, too. The delivery rate of T-N is calculated from 0.2 to 0.3 in the dry season, and from 0.31 to 0.39 in a flood, respectively. The delivery rate of T-P is calculated to more than 0.3 in the dry season, and 0.11 in a flood. It is similar values which the average annual delivery rate of T-P is 0.08. Therefore, the measured delivery rate of Sapkyo reservoir can be applicable such as a delivery rate of similar features of the terrain and land use.
