노화가 진행됨에 따라 근육은 감소 현상(sarcopenia)을 나타낸다. 근육의 감소는 노인의 의료비 증가와 직접적인 관련성은 없어 보이지만, 근육의 감소가 근력의 감소로 연결되어 체력의 약화, 활동성의 감소, 낙상의 증가 등과 같은 독립적인 생활을 감소시킨다. 이는 신체장애로 연결되며, 또다시 당뇨, 비만, 고지혈증, 고혈압 등과 같은 만성퇴행성 질환으로 연결된다. 결국, 근감소증은 사망률을 상승시키는 잠재 위험요인이 된다. 본 연구는 탄력밴드 운동을 통한 근감소증 예방과 관련된 변인인 신체조성 및 체력의 향상된 변화와 더불어 운동 중단에 따른 운동효과의 상쇄(相殺) 정도를 살펴보는데 있다. 본 연구의 피검자는 S시 J구 J노인복지관 운동프로그램에 참가하는 60-70대의 노인 14명으로 선정하였다. 12주 동안의 탄력밴드 운동은 주2회의 빈도로 실시하였다. 측정시기는 12주간의 통제전, 통제후(운동전), 12주간의 운동 후(운동중단 전), 12주간의 운동중단 후로 신체조성 과 체력 변인을 측정하였다. 12주간의 통제전·후 신체조성과 체력 변인에는 통계적인 유의차가 나타나지 않았으나, 12주간의 운동전·후 신체조성의 체중(t=2.978, p=0.001), 체질량지수(t=3.502, p=0.004), 체지방율(t=2.216, p=0.045), 근육량(t=-3.837, p=0.002), 내장지방면적(t=5.186, p<0.001), 허리-엉덩이 둘레비(t=3.045, p=0.009) 모든 변인에서, 체력의 2분 제자리 걷기(t=-6.891 p<0.001), 덤벨들기(t=-4.702, p<0.001), 의자에서 일어섰다 앉기(t=-4.860, p<0.001), 의자앉아 앞으로 굽히기(t=-5.910, p<0.001), 등 뒤에서 손잡기(t=-3.835, p=0.002), 244cm 왕복 걷기(t=7.560, p<0.001)의 모든 변인에서 운동의 효과를 나타내었고, 그 효과가 12주간의 운동중단 후에도 신체조성의 체중(t=2.323, p=0.037), 체질량지수(t=2.503, p=0.026), 근육량(t=-3.137, p=0.008) 변인에서, 체력의 2분 제자리 걷기(t=-6.489 p<0.001), 의자에서 일어섰다 앉기(t=-4.694, p<0.001), 의자앉아 앞으로 굽히기(t=-3.690, p=0.003), 244cm 왕복 걷기(t=7.539, p<0.001)의 변인에서 그 유지가 지속되었다. 노인에게 있어서 탄력밴드 운동은 신체조성 및 체력에 긍정적인 영향을 나타내며, 그 운동의 효과가 12주가 경과되어도 유지되고 있음을 확인할 수 있었다.

본 연구는 노인 소득원을 국가소득. 시장소득, 가구소득, 전체소득으로 구분하여 분담구조를 살펴보고, 노인특성에 따른 차이를 분석하여 노인특성에 맞는 노후소득보장체계 구축자료로 활용하기 위한 것이다. 분석결과 첫째, 노인 소득원은 시장소득이 305만원으로 가장 많았고, 국가 248만원, 가족 218만원의 순으로 시장에 많이 의존하고 있었다. 둘째, 인구사회학적 특성에 따라서는 남성노인이 여성보다 국가, 시장을 통해 소득을 많이 얻는 반면, 여성은 가족을 통해 많이 받고 있었다. 연령에 따라서는 시장소득은 젊은 노인일수록 월등히 많고, 가족소득은 고령 노인일수록 많았다. 시장소득이 많은 비중을 차지하는 노인소득구성의 특성상 경제활동을 할 수 있는 젊은 노인들의 전체소득이 많았다. 지역에 따라서는 국가소득, 가족소득은 도시화된 지역이 많은 반면, 시장소득은 읍면지역이 많았으며, 배우자 유 무에 따라서는 국가소득, 시장소득은 배우자가 있는 경우가 많은 반면, 가족소득은 없는 경우가 더 많았다. 셋째, 소득수준에 따라서는 국가소득, 시장소득은 고소득층이 가장 많은 반면 가족소득은 고소득층이 가장 적었다. 저소득층 노인의 경우 가족소득에 의존하고 있어서 빈곤상태가 지속될 가능성이 큰 것이다. 넷째, 건강상태에 따른 소득원별 차이를 분석한 결과 건강수준이 좋을수록 국가와 시장소득이 높고 낮을수록 가족 등 사적인 영역에 많이 의존하고 있었다. 이상의 분담구조별 차이는 요인분석결과에서도 동일하게 나타났다. 따라서 우리나라 노인은 시장과 가족소득 의존이 서구국가보다 높으며 여성, 저소득층, 건강상태가 나쁜 노인 등 취약한 특성을 가진 경우에 가족 시장소득에 많이 의존하고 있어서 공적소득지원체계의 보완이 필요하다.

A cross-sectional study involving 400 mothers was conducted in the Manya Krobo district of Ghana with the objective of studying household dietary practices, quality of diets and family nutritional status of rural Ghana, A combination of methods, including structured interviews using questionnaire, dietary assessments and anthropometry was used to collect data for the study. The data obtained was analyzed using Statistical Package for Social Sciences (SPSS) Version 10 in Windows. Means and standard deviations were generated for continuous variables and frequency distribution for categorical variables. Most women consumed meals three times a day but only a few (12.5%) cooked all three meals at home. Breakfast and lunch were the two main meals purchased from food vendors. The most frequently consumed food items on daily basis were the starchy staples, maize, fish, pepper, onion, tomato and palm fruits. The nutritional qualities of diets were poor in terms of calcium and the B-vitamins. A significant proportion of the women were nutritionally at risk of being either underweight (12%), overweight (17%) or obese (5%). For adequate nutrition in this population, nutrition education intervention programs aimed at improving nutrient intake through improved diet diversity and increased use of local foods rich in calcium and the B-vitamins needs to be undertaken. There is also the need to intensify education on excessive weight gain and its attendant health problems in the area.

A total of 19 species of three genera Dinophysis, Histioneis, and Parahistioneis of the family Dinophysaceae are reported here from samples obtained using a 20-µm mesh net from June 2006 to December 2014 around Jeju Island including the East China Sea, and 16 of these species are new to Korean waters. A checklist of the three genera of dinoflagellates reported from coastal and oceanic Korean waters is presented. Short descriptions and synonyms are given for each species. The dinoflagellates of the family Dinophysaceae belong to mostly marine species, and include many tropical and/or subtropical species. Recently, the composition of dinoflagellate species has changed around Jeju Island as well as in Korean waters due to global warming and climate change. Tropical and subtropical dinoflagellates occur frequently in the coastal waters of Jeju Island, which reflects the ecosystem shift around the sea adjacent to Jeju Island from a temperate to a subtropical / tropical region.

Public rental apartment has suffered social exclusion problem, stemmed from its closed planing for a very specific range of the disadvantaged population. Thereby, it has been recognized as a disliked residential facility. To alleviate this problem, various approaches have been tried such as ownership-tenant mixture, and different unit size mixture. The purpose of this study is to grasp the expected social relation among neighboring residents according to socially integrative planing elements such as ownership, unit size and family life cycle match. Thirty eight graduate students in architecture and housing field responded to the questionnaire which was specifically made to identify relations of 28 neighboring situations based on $2{\times}2{\times}2$ variable composition. Frequency, percentage and MDS(multidimensional scaling) were used to analyze data. As a result, the order of preferred matchy were identified. The match between rental/small/children group and ownership/middle/children group was turned out to be the most desirable while the match between rental/small/children family group and rental/small/elderly group was found the least desirable. Spatial representations of the relationships among 8 household types were delineated. In conclusion, the definite patterns of the favorable and unfavorable match were found. This result is expected to be used as a reference in developing a strategic match to promote the rental apartments social integration in Korea.

The purpose of this study was to investigate predictors concerning preschoolers' ability to read words, in terms of their sub-skills of alphabet knowledge, phonological awareness, and phonological processing. Fourteen literacy sub-tests and three types of reading tasks were administered to 289 kindergartners aged 4 to 6 in Busan. The main results are as follows. Sub-skills that predicted reading ability varied with children's age. Irrespective of children's age groups, knowledge of consonant names and digit naming speed commonly explained the reading of real words. In contrast, skills of syllable deletion and phoneme substitution and knowledge of alphabet composition principles were related to only 4-year-olds' reading skills. Exclusively included was digit memory in predicting 5-year-olds' reading abilities, and knowledge of vowel sounds in 6-year-olds' reading skills. The type of reading task also influenced reading ability. A few common variables such as knowledge of consonant names and vowel sounds, digit naming speed, and phoneme substitution skill explained all types of word reading. Syllable counting skills, however, had predictive value only for the reading of real words. Phoneme insertion skills and digit memory had predictive value for the reading of pseudo words and low frequency letters. Likewise, knowledge of consonant sounds and vowel stroke-adding principles were significant only for the reading of low frequency letters.

The order of Rhododendro-Quercetalia mongolicae representing temperate oak forests in Korea was characterized in terms of presence of taxa of different rank. 140 releves were analysed for percentage contribution of each species, genera and families in syntaxa under consideration as well as extracton of diagnostic genera and families for syntaxa by an ordination technique. The Rhododendro-Quercetalia is characterized by high diversity of tree and shrub species contributing 40% of the total floristic composition as well as by a high contribution of the genus Rhododendron and the absence of the genus Fagus, characteristic of the QuercoFagetea sensu lato. The character families for the Rhododendron and Quercus include Liliaceae and Compositae, whereas Acer, Carex, Viola, Rhododendron and Quercus are the most common among genera. Rhododendron and Quercus are regarded as the transgressive cheractergenera, whereas the families of Pinaceae and Ericaceae are considered companions (in sense of the terminology of the Braun-Blanquet syntaxonomy) for the order. Family appeared to be an inadequate rank for diagnoses of alliances and suballiances. On the other hand, genus was found to be the most effective rank in differentiating the alliances and suballiances. The Lindero-Quercenion shares the same character-genera with the order Rhododendro-Quercetalia. Character genera of the suballiances Callicarpo-quercenion are Carpinus, Styrax, Smilax and Callicarpa, and those of the Pino-Quercion list Euonymus, Saussurea and Tilia.

The use of autogenous tooth bone graft material has been commercialized since 2008. Autogenous tooth bone grafts always require that the tooth of the patient be extracted, and thus, the use of graft material are limited in many cases. For solution of limitation in quantity and concurrent use of autogenous tooth bone graft material, the grafting of familial teeth has been suggested. It has the following advantages: the teeth of family members are used as bone graft materials, the genetic composition is identical, and potential genetic and infectious risks can be minimized. Because the teeth of family members are used, a good tissue affinity is obtained, and thus, superior bone generation rates compared to those observed for allogenic or xenogenic bones can be anticipated. We used familial tooth bone-graft materials for alveolar ridge augmentation, socket preservation, and maxillary sinus graft in some cases. In most cases, the impacted third molars of their children were prepared as bone graft material and were used for surgery. In one case, the impacted third molar from the patient's brother was used as bone graft material. We obtained satisfactory result and these cases are reported herein.
