Because of developing medical science, lengthening the average life span and so on, the population of the elderly goes on increasing. The population of the healthy and high-income old people are increasing, also. So this study aimed to grasp the facilities and program situation of the welfare hall for the elderly as a welfare-leisure institution. The elderly be going to a hall are anticipated too many, based on the number of the hall per local old people. The majority of the hall are organized similar spaces and progams in them. There are almost not different things among the welfare halls and the locations. So they should be set on the aged' higher requirements and the old man's need varying in different localities. Also, 'gyoungrodang' remodeled in facilities and programs near their houses is likely to be recommended as the nest best thing.

The elder population is growing rapidly in Korea nowadays. Therefore, a demand for adaptable installation standard of residential space for the elderly is increasing with growth of the elder population. This study analyzed actual state by interviewing manager, surveying actual measurement and using draft of Elderly nursing facility which is for senile patients. As a result of the survey for size and facilities, facilities for elderly safety, accommodation per a person and room size per a person are below to standard. Therefore, establishing adaptable design standard is needed which is to make safe and fresh living environment for the elderly.

Plants of G. furcata were divided into four variant populations. The habit characteristics, external and internal morphology were analysed quantitatively in order to clarify their morphological variation. Among four variant populations, type I(typical G. furcata type) and type II(G. furcata f. intricata type) may be influenced by the time when the develop from the crustose basal discs and the tidal level. Type III is the immature plants, and type IV (G. furcata f. coliformis type) is a G. furcata population in late spring after the luxuriant season. For the reason, the formas of G. furcata f. intricata and f. coliformis are no more valid in Gloiopeltis furcata.

Recent cities have been extended by the urban population's growth. But, despite the extension of the residence in the edge of metropolitan, the urban sprawl has appeared because of insufficiency of infra structure. Therefore this study implemented the survey of the resident consciousness, on the base of it, aimes to provide the data for developments.

An increase in population of advanced age people according to medical development and progress of small family system by industrial development, changed our traditional large family system and paved way for creating a new dwelling culture in Korea. The purpose of this study are consisted of user paid welfare housing for elderly, pointing out the typical problems on present the elderly housing by check- list.

The Korean National Institute of Fisheries Science (NIFS) has biannually (spring and fall, respectively) deployed a bottom trawl survey along the coastal areas for last decade, taking samples on a regular basis (i.e., a systematic sampling). Despite the availability of the survey data, NIFS has not yet officially reported the estimates of the groundfish population sizes as well as has not evaluated uncertainty of the estimates. The objectives of our study were to infer the relative size of a fish population, applying two different sampling techniques (namely simple and stratified sampling) with different observation units to the NIFS survey data, and to compare those two techniques in bias and precision. For demonstration purposes, we used data on Pacific cod (Gadus macrocephalus) collected by the 2011-2015 surveys, and the results of simple and stratified sampling showed that the point estimates and precision varied by observation unit as well as the sampling technique.

Production of spring wheat, the major crop in Mongolia, accounts for 98% of the cultivated area. Understanding genetic variability in existing gene bank accessions is critical for collection, conservation and use of wheat germplasms. To determine genetic diversity and population structure among a representative collection of Mongolian local wheat cultivars and lines, 200 wheat accessions were analyzed with 15 SSR markers distributed throughout the wheat genome. A total of 85 alleles were detected, with three to five alleles per locus and a mean genetic richness of 5.66. Average genetic diversity index was 0.69, with values ranging from 0.37-0.80. The 200 Mongolian wheat accessions were mainly divided into two subgroups based on structure and phylogenetic analyses, and some phenotypes were divergent by the subgroups. Results from this study will provide valuable information for conservation and sustainable use of Mongolian wheat genetic resources.

To examine the population development of the dinoflagellates, Ceratium furca and Ceratium fusus, daily field monitoring was conducted between April and July 2003 in the temperate coastal water of Sagami Bay, Japan. During the study period, the concentrations of C. furca were always lower than those of C. fusus. A sharp increase in the densities of both species was recorded on 5 May showing the maximum cell concentrations (C. furca = $14,800\;cells\;L^{-1}$, C. fusus = $49,600\;cells\;L^{-1}$). In the 7 days prior to the May bloom of the Ceratium species (29 April to 1 May), the highest density of the heterotrophic dinoflagellate Noctiluca scintillans was observed. Additionally, a second bloom of C. fusus occurred on 22 July. Here, two causes of the significant increases in the Ceratium populations during the two blooming periods (first time; 1 to 8 May, second time; 15 to 22 July) are presented. First, an increase in the nutrients of the surface layer regenerated by the breakdown of blooms by N.scintillans could be considered as a major cause of the population increase of the two Ceratium species. Second, a decrease in salinity (to 27 psu) was correlated with the later bloom of C. fusus. These results suggest that the population development of the two Ceratium species requires nutrients regenerated after the reduction of the diatom population by N. scintillans and, for C. fusus, continuous low salinity conditions, compared to other environmental factors during the rainy season.

To investigate the population densities of potential malaria vectors, Anopheles species were collected by light traps in malaria endemic areas, Paju and Gimpo, Gyeonggi-do of Korea. Five Anopheles Hyrcanus sibling species (An. sinensis, An. pullus, An. lesteri, An. kleini, and An. belenrae) were identified by PCR. The predominant species, An. pullus was collected during the late spring and mid-summer, while higher population consists of An. sinensis were collected from late summer to early autumn. These 2 species accounted for 92.1 % of all Anopheles mosquitoes collected, while the other 3 species accounted for 7.9%. Taking into account of these population densities, late seasonal prevalence, and long-term incubation period (9-13 months) of the Korean Plasmodium vivax strain, An. sinensis s.s is thought to play an important role in the transmission of vivax malaria in the study areas.

야광충 $Noctiluca$ $scintillans$의 시공간적 변동과 생태학적 특성을 이해하기 위해서 그들의 개체수 밀도와 환경인자를 광양만 20개 정점과 진해만 23개 정점에서 2010년 춘계, 하계, 추계, 동계의 계절 조사를 수행하였다. 야광충 $N.$ $scintillans$는 광양만과 진해만에서 $15{\sim}27^{\circ}C$ 수온 범위의 춘계와 하계에 높은 밀도가 유지된 반면, 동계와 추계는 그들의 개체수가 감소하였다. 두 해역에서 야광충의 개체수는 수온과 유의한 상관관계가 성립되었고, 이는 수온 증가와 더불어 $N.$ $scintillans$의 증식이 활발해 진다는 것을 의미한다. 특히, 두 해역에서 4계절 모두 야광충의 출현은 확인하였으나, 저온(<$4^{\circ}C$)과 저염(<12 psu)에서 그들 개체를 관찰할 수 없었다. 먹이생물의 지표가 되는 Chl.$a$ 농도와 야광충의 개체수는 유의한 상관관계를 확인할 수 없었으나, 두 해역에서 Chl.$a$ 농도가 현저하게 높았든 춘계와 하계에 야광충 개체수밀도가 높게 나타났다. 결과적으로 식물플랑크톤의 현존량은 야광충 $N.$ $scintillans$의 개체수 증감을 제어하는 중요한 인자로 판단되었다.
