Waterproof work is closely related to the performance of the building structure and a falling-off in durability. This study focuses on finding out the defect characteristics and problems of waterproof construction classified by work types and construction methods, through waterproof work companies. The defections of construction method are classified into defect, design, construction, material, surface for working, and site control, in order to find out defect types and defect characteristics which will be used to construct devised the improvement plan for quality management of waterproof construction. The result of this study can be summarized as follows: there are many defections due to not observing the specific regulations, and after construction, defections caused by desquamation are shown in various places- Therefore, the improvement plan for quality management of waterproof construction is that adequate construction followed by technical specifications and construction workers' improvement in technical skill are necessary.

Bee stings can cause various skin reactions that usually resolve over several days; however, in some patients the venom acts as an allergen, causing a severe immunological response such as anaphylaxis. Bee stings can also induce chronic inflammation because the barbed stinging apparatus and venom sacs, along with the nerve plexus, can lodge in the skin. Chronic non-specific low back pain is the most common medical problem for which patients seek complementary and alternative medical treatment, including bee venom acupuncture. Bee venom acupuncture involves injecting diluted bee venom into acupoints and is used for arthritis, pain, and rheumatoid diseases. Here we report a 75-year-old man with acute urticaria and skin eruption with eosinophilia and interstitial pneumonia 6 weeks later after receiving 5 times bee venom acupuncture.

본 연구는 상악 유전치부의 치간공간과 인접면 우식의 상관관계를 평가해보고자 하였다. 익산에 거주하는 만3-7세의 어린이 555명을 대상으로 하였으며 탐침이 통과하는지 여부로 치간공간이 있음과 없음으로 분류하였고 와동이 형성되었거나 법랑질 표면이 연화되었을 경우 인접면 우식이 존재하는 것으로 판단하였다. 연구 결과 다음과 같은 결론을 얻었다. 1. 상악 유전치부의 치간공간은 영장류 공간이 77.4%, 발육공간이 유측절치와 유중절치 사이에서 54.4%, 양유중절치 사이에서 39.0%로 나타났다. 2. 인접면 우식발생율은 우측유견치가 6.3%, 우측유측절치가 14.7%, 우측유중절치가 33.5%, 좌측유중절치가 33.7%, 좌측유측절치가 16.0%, 좌측유견치가 4.7%로 나타났다. 3. 치간공간의 수가 많을수록 상악 유전치의 우식발생율은 낮아졌으나 그 상관관계(r=0.024)는 미약하였다. 4. 상악 유전치부에 공간이 존재하지 않을 경우 존재할 때 보다 평균 우식발생율이 높았으며, 치간공간이 전혀 존재하지 않는 경우 한 곳이라도 치간공간이 존재하는 경우보다 평균 우식발생율이 2배 이상 높은 것으로 나타났다. The purpose of this study was to assess the relationship between interdental spaces and proximal caries in maxillary anterior primary teeth. 555 children aged 3-7 inhabit in Iksan were divided into two groups, depending on the presence of interdental space which was detected by a dental explorer. They were determined to have proximal caries if cavity was formed or the enamel surface was softened. The results were as follows : 1. Regarding interdental spaces, 77.4% had primate spaces; 54.4% had developmental spaces between central and lateral incisor, and 39.0% between central incisors. 2. Interproximal caries incidences in right primary canine, lateral incisor, and central incisor were 6.3%, 14.7%, and 33.5%, respectively. Also interproximal caries incidences in left primary central incisor, lateral incisor, and canine were 33.7%, 16.0%, and 4.7%, respectively. 3. Children with more interdental spaces had less caries incidence, but the relationship was weak(r=-0.024). 4. The mean caries incidence was higher in absence of interdental space of maxillary primary incisors than in presence of space. The mean caries incidence with no interdental space was twice as high as that with presence of interdental space.

Generation and transportation of runoff and pollutant loads within watershed generated eutrophication at Daecheong reservoir. To improve water quality at Daecheong reservoir, the best management practices should be developed and applied at upper watersheds for water quality improvement at downstream areas. In this study, two small watersheds of upper Daecheong reservoir were selected. The Long-Term Hydrologic Impact Assessment (L-THIA) model has been widely used for the estimation of the direct runoff worldwide. To apply the L-THIA ArcView GIS model was evaluated for direct runoff and water quality estimation at small watershed. And the Web-based Hydrograph Analysis Tool (WHAT) was used for direct runoff separating from total flow. As a result, the $R^2$ (Coefficient of determination) value and Nash-Sutcliffe coefficient value for direct runoff comparison at An-nae watershed were 0.81 and 0.71, respectively. And the $R^2$ value and Nash-Sutcliffe coefficient value at Wol-oe were 0.95 and 0.93. The $R^2$ value of BOD, TOC, T-N and T-P at An-nae watershed were BOD 0.94, TOC 0.81, T-N 0.94 and T-P 0.89. And the $R^2$ value of BOD, TOC, T-N and T-P at Wol-oe watershed were BOD 0.80, TOC 0.93, T-N 0.86 and T-P 0.65. The result that estimated pollutant loadings using the L-THIA ArcView GIS model reflected well the measured pollutant loadings except for T-P in Wol-oe watershed. With L-THIA ArcView GIS model, the direct runoff and non-point pollutant (NPS) loadings in the watershed could be analyzed through simple input data such as daily rainfall, land uses, and hydrologic soil group.

‘옥매(Okmae)’는 ‘도요노까(Toyonoka)’를 모본으로 하고 ‘매향(Maehyang)’을 부본으로 하여 교배하여 과실품질이 우수하고 화방당 화수가 적당하여 적과노력이 절감되는 특성에 근거하여 선발한 촉성재배용 품종이다. 2006년 초세가 왕성하며 당도와 경도가 높고 대과형인 96-2번 개체를 선발, 2007-2009년에 촉성재배작형으로 특성검정과 생산력 검정을 수행하여 ‘경남 1호’로 계통명을 부여하고 농가실증 시험을 거쳐 ‘옥매’로 명명하였다. ‘옥매’의 주요 특성은 초세가 왕성하고 초형은 직립형으로 엽수는 적으며 엽형은 타원형이다. 화경장은 길고 화방당 화수는 9-10개로 적어 적과 노력이 적게 든다. 과형은 원추형이며 과색은 선홍색으로 광택이 있다. 주당 수확과수는 21.9개로 적지만 대과의 비율이 높고 평균과중이 26.0g으로 무거워 다수확이 가능하다. 당도가 11.6°Brix로 높고 산도는 0.37%로 낮으며, 경도는 14.5g·mm<SUP>-2</SUP>로 ‘아끼히메’에 비해 우수하여 저장성이 뛰어나다. 탄저병에 저항성이 없으며, 흰가루병도 다소 약하지만, 방제에 유의하면 고품질의 딸기를 생산할 수 있다. A new strawberry cultivar (Fragaria × ananassa Duch.) ‘Okmae’ was developed from a cross between ‘Toyonoka’ and ‘Maehyang’. This cultivar has a good fruit quality and suitable number of flowers per cluster for labor saving in fruit thinning. ‘Gyoengnam No. 1’ was selected as an elite line with vigorous plant growth, higher soluble solids content and fruit firmness after examining its characteristics and productivity in forcing cultures from 2007 to 2009. Farmer’s field trial of ‘Gyoengnam No. 1’ was conducted in 2010 and it was registered as ‘Okmae’ thereafter. The general characteristics of ‘Okmae’ are vigorous growth habit, erect plant type, less number of leaf and elliptic leaf shape. ‘Okmae’ has long peduncle and 9-10 flowers per flower cluster which need less labor for fruit thinning. Fruits of ‘Okmae’ are conical having a bright red and glossy skin color. Although ‘Okmae’ has a smaller average fruit number per plant of 21.9 than that of the control cultivars, it’s possible to produce high yield because of greater fruit weight of 26.0 g. ‘Okmae’ showed a high soluble solids content of 11.6 °Brix, low acidity of 0.37%, and high firmness of 14.5 g·mm<SUP>-2</SUP>. It is sensitive to anthracnose and powery mildews, but high-quality strawberry can be harvested by using effective control measure.

<P><B>Abstract</B></P> <P>Core–shell structured Fe<SUB>3</SUB>O<SUB>4</SUB>@SiO<SUB>2</SUB> nanoparticles were synthesized through a facile in situ surface-treatment process. Surface treatments of the as-prepared Fe<SUB>3</SUB>O<SUB>4</SUB> nanoparticles with acid or base caused changes in the shape of spherical particles agglomerated into clusters. The morphological changes of the particles experienced an abrupt change depending on the concentration of the treated acid or base, and the magnetization properties and surface characteristics corresponding to these behaviors were studied. As a result, optimum surface-treatment conditions for depositing SiO<SUB>2</SUB> on the surface were established, and the derivation condition basically included the ideal environment for coating SiO<SUB>2</SUB>. It was possible to coat SiO<SUB>2</SUB> using a sol–gel reaction without going through the removal of residual organics and a solvent displacement process. About 8 nm of a single coating layer was homogeneously formed due to excellent initial dispersibility of Fe<SUB>3</SUB>O<SUB>4</SUB> nanoparticles according to the modified surface characteristics.</P>
