일상 속에서 간염은 대수롭지 않게 취급되거나, 아예 사람들의 관심 밖에 있는 경우가 많다. 하지만 간염은 피로와 감기 몸살 증상을 일으키는 등 일상생활에 지장을 줄 뿐만 아니라 방치할 경우 간경화나 간암과 같은 치명적인 간 질환으로 발전해 당신의 생명을 위협할 수도 있다.

겨울철 난방기가 끝남에 따라 겨우내 사용한 보일러에 대한 손질이 필요한 때가 돌아왔다. 겨울철동안 계속된 가동으로 그을음이 끼거나 무리가 가해진 보일러를 그냥 방치해 둘 경우 연소효율이 떨어지거나 수명이 단축되는데 간단한 청소나 손질로 이를 예방할 수 있다. 에너지관리공단이 추천하는 간단한 보일러 청소 및 관리 방법을 소개한다.

'70년대 이후 잡는 어업의 발달과 함께 통발.자망등의 어구가 크게 증가하여 국내 연근해 해역에는 약 40여만 톤의 폐기물이 바다 속에 침적되어 있는 것으로 추정되고 있으며 특히 주요어장 및 폐기물 밀집도가 높은 해역에는 약 115천 톤의 폐기물이 방치되어 있는 것으로 조사되고 있다.

고혈압은 기본적으로 혈관병이다. 이 때문에 혈관이 있는 곳이면 어디든지 고혈압의 영향을 받을 수 있다. 집중 타격을 받는 곳이 심장에 영향을 공급하는 관상동맥, 뇌동맥, 신장으로 혈관과 관계된 눈도 예외가 아니다.

우리 주위엔 병ㆍ의원에 가고 싶어도 가지 못하거나 방치되고 있는 환자들이 많다. 현재의 가정간호제도를 진단하고 선진국과 비교해 봄으로써 바람직한 정책 방향을 제시하고자 한다.

Physical, mechanical and deteriorating properties of Phellodendron amure were investigated. Air dried density located indoor was 0.41 but $0.43g/cm^3$ outdoor. In oven dry shrinkage, T/R ratio for located indoor was 1.40 but 1.32 outdoor. Hygroscopic property at $40^{\circ}C$ with 90% relative humidity was 16.30% for indoor and 15.80% for outdoor. Compressive strength for outdoor conditioned sample was 43.81 MPa but 40.33 MPa for indoor conditioned. Also bending strenght for outdoor conditioned was 84.63 MPa but 68.80 MPa for indoor conditioned. Impact strength was 3.43 and $4.00J/cm^2$ indoor and outdoor, respectively. Hardness at cross-section was 47.92 and 49.20 MPa indoor and outdoor, respectively. With one-year conditioning at indoor or outdoor, there was no significantly different in strength properties, which came from strong resistance for deterioration. Also Phellodendron amure wood showed dimensionally stable raw material based on low T/R ratio.

Changes of the species diversity and development of vegetation structure during abandoned field succession after shifting cultivation were investigated in Pyoungchang, Gangwon-Do, Korea. The height of top layer tended to increase rapidly during the earlier successional stages and stabilize in the later successional stage. The heights of top layer in the 10, 20, 50 and 80 year old-field were 4, 9, 18 and 18 m, respectively. In this region, thirty five year after abandonment need for the development to the normal forest formed by 4 stratum structure, tree, sub-tree, shrub and herb layer. Among the vegetation values, Ivc showed a tendency to increase logarithmically, and Hcl a tendency to increase linearly during abandoned field succession. Species diversity showed the peak in mid-successional stages ($10{\sim}20$ year old-field) and declined slightly thereafter. Species diversity was correlated closely with the species richness than the evenness. The most woody species established in the earlier stage ($2{\sim}6$ year old-field) and turned over their dominance step by step during succession. These results support the IFC model proposed by Egler (1954).

As the number os working-class households has increased and As the number of working-class households has increased and the birth rate has decreased, more than a third of all elementary school students are left alone. While elementary schools across the nation have implemented a policy of after-school care, even that has reduced the number of classrooms in the government. As such, parents cannot avoid leaving their children alone at home and wonder about their day. For these parents and older elementary school students, they came up with a service that allows them to plan and implement their own work. The service enables children to develop self-regulating learning skills and allows them to receive feedback through the app on what plans and practices a child left alone at home is planning.
