  • The main objective of this study is to examine the situations of group-homes for the elderly and clarify the problems of them. This study investigates the present conditions of welfare facilities and supply conditions. 4 group-homes were surveyed in Jeonju and Kwangju cities. Data was collected through various ways including the survey conducted by facility operators, the measurement of living space, and photo-takings. The major results of this study are as follows: 1) With the introduction of nursing care insurance in 2008, the increase of the demand and supply to group-home will be expected, due to less cost for recuperation. The care of elderly in homelike atmosphere is effective to the elderly suffering from dementia. Therefore, it is proper that the supply of group-homes for dementia will be needed. 2) Group-homes for the elderly are being supplied under the standards of welfare facilities in the present. Separate supply standards, however, are needed because they are not suitable for small scale group-homes. 3) To supply Group-homes for the elderly on a one-unit basis would cause various problems such as economical unreality, personnel distribution and so on. It is necessary to supply more than two units for more efficient management. 4) The management of group-homes for the elderly is financially unstable because the operating funds heavily depend on the users or people who are connected with the facilities through private networks. Therefore, additional support is needed to settle the financial problem. It would be helpful to build the public networking that provides information about the group-home for the elderly for the public. 5) In case of the increase in the supply of the group-home in a residential area, it could be helpful to promote the group-home to the public. 6) The operators state that the main problems of group homes for the elderly lie in financial difficulties and the shortage of professionals and volunteers. The financial, personnel, and material support for personnel and the supervision of management are required for the transparency and effectiveness of the facility management. In addition, the closer network and cooperation system with the community is required. 7) The present living environments for group-homes for the elderly leave much room for improvement, considering the physical condition of the elderly. The more careful selections in the color, shape, material, and equipment of the facilities should be made for the convenience of the elderly users.

  • This study tried to find the clue to Seokrok province by comparing Seokrok used in painting culture properties with Seokrok ore from domestic occurrence and imported Seokrok ore. To this end, chemical and mineralogical characteristics of painting cultural properties were identified with portable X-ray Florescence (p-XRF), micro X-ray diffraction (micro XRD) and SEM/EDS Analysis. To obtain Pb isotopic ratio, the Pb contained in Seokrok has been analyzed with Thermal Ionization Mass Spectrometer. Atacamite (or botallackite) and small quantity of brochantite were identified from Seokrok in Dancheong, and malachite was also identified from Buddhist painting besides those two ingredients. Without distinction of type, most Seokrok used in painting cultural properties is atacamite composed of Cu and Cl. From Pb isotope analysis, it was found that Seokrok in painting cultural properties was closer to that of north Korea, north China and Japan than south Korea as in regional division for East North Asia suggested by Mabuchi. The Pb isotopic ratio of domestic green mineral belongs to the distribution of Seokrok inside the painting cultural properties but imported malachite showed considerably difference. Considering the fact that atacamite, the main mineral of Seokrok in painting cultural properties is rarely produced from southern mine of the Korean Peninsula and the result of Pb isotope analysis.

  • When producing rice products, it is very important to select suitable raw materials. Therefore, in this study, the quality characteristics of 16 rice cultivars were quantified to determine the criteria for evaluating the machinability of raw rice. The L value, which can affect the color of porridge prepared from rice, was the greatest for Hwaseonchalbyeo (84.17). The water-binding capacity, related to water interaction, was high in Hyangcheola (113.2%), and water solubility was high in Shingil (22.3%). Dodamssal (42.3%, 70.7 RVU) and Hwaseonchalbyeo (4.7%, 27.8 RVU) showed lower final viscosity compared to the cultivars in which the amylose content was medium groups (16.4~21.2%, 173.6~277.2 RVU). Specifically, cultivars with high or low amylose content had a low viscosity. The characteristics of the distribution of raw rice quality data were confirmed through 11 histograms. Furthermore, amylose content vs. water solubility, water solubility vs. peak viscosity, and peak viscosity vs. final viscosity showed high correlations (r=0.542, -0.569, and 0.836 respectively, p<0.01), and clear cultivar discrimination by the standard error of the mean (0.765~10.811). In conclusion, amylose content, water solubility, and peak viscosity were considered the most suitable characteristics for the quality evaluation of raw rice.

  • The purpose of this study is to investigate climatological variations from the temporal and spatial surface particulate organic carbon (POC) estimates based on SeaWiFS spectral radiance, and to determine the physical mechanisms that affect the distribution of pac in the Gulf of Mexico. 7-year monthly mean values of surface pac concentration (Sept. 1997 - Dec. 2004) were estimated from Maximum Normalized Difference Carbon Index (MNDCI) algorithm using SeaWiFS data. Synchronous 7-year monthly mean values of remote sensing data (sea surface temperature (SST), sea surface wind (SSW), sea surface height anomaly (SSHA), precipitation rate (PR)) and recorded river discharge data were used to determine physical forcing factors. The spatial pattern of POC was related to one or more factors such as river runoff, wind-derived current, and stratification of the water column, the energetic Loop Current/Eddies, and buoyancy forcing. The observed seasonal change in the POC plume's response to wind speed in the western delta region resulted from seasonal changes in the upper ocean stratification. During late spring and summer, the low-density river water is heated rapidly at the surface by incoming solar radiation. This lowers the density of the fresh-water plume and increases the near-surface stratification of the water column. In the absence of significant wind forcing, the plume undergoes buoyant spreading and the sediment is maintained at the surface by the shallow pycnocline. However, when the wind speed increases substantially, wind-wave action increases vertical motion, reducing stratification, and the sediment were mixed downward rather than spreading laterally. Maximum particle concentrations over the outer shelf and the upper slope during lower runoff seasons were related to the Loop Current/eddies and buoyancy forcing. Inter-annual differences of POC concentration were related to ENSO cycles. During the El Nino events (1997-1998 and 2002-2004), the higher pac concentrations existed and were related to high runoffs in the eastern Gulf of Mexico, but the opposite conditions in the western Gulf of Mexico. During La Nina conditions (1999-2001), low Poe concentration was related to normal or low river discharge, and low PM/nutrient waters in the eastern Gulf of Mexico, but the opposite conditions in the western Gulf of Mexico.

  • Cost efficiency is today the primary requirement in the paper and board industry. This has led therefore, to a greater preponderance of products with specifically designed functionality to take account of current industry needs. Continually increasing machine coating speeds together with these new coating colour components have put more emphasis on the importance of the correct rheology and water retention of the coating colours to achieve good runnability and end product quality. In the coating process, some penetration of the aqueous phase, to the base paper or board must occur to anchor the pre-coating to the base or the topcoat to the pre-coat. The aqueous phase acts as a vehicle not only for the binder, but also for the other components. If this water or material penetration is not controlled, there will be excessive material shift from the coating colour to the base, before immobilization of the coating colour will stop this migration. This can result in poor machine runnability, unstable system and uneven coating layer, impacting print quality. The performance of rheology modifiers or thickeners on the coating color have tended to be evaluated by the term, "water retention". This simple term is not sufficient to explain their performance changes during coating. In this paper we are introducing a new concept of "material retention", which takes note of the total composition of the coating colour material and therefore goes beyond the concept of only water retention. Controlled material retention leads to a more uniform z-directional distribution of coating colour components. The changes that can be made to z-directional uniformity will have positive effects on print quality as measured by surface strength, ink setting properties, print gloss, mottling tendency. Optical properties, such as light scattering, whiteness and light fastness delivery should also be improved. Additionally, controlled material retention minimizes changes to the coating colour with time in re-circulation giving less fluctuation in quality in the machine direction since it more closely resembles fresh coating for longer periods. Use of the material retention concept enables paper and board producers to have more stable runnability (i.e. lower process costs), improved end product quality (i.e. better performance of used chemicals) and/or optimized use of coating colour components (i.e. lower total formulation cost)

  • This study was carried out to investigate proper modified atmosphere condition of king oyster mushroom (Pleurotus eryngii) during cold storage and distribution. King oyster mushrooms were divided into two treatments: $1{\mu}L/L$ 1-methylcyclopropene for 20 hours at $0^{\circ}C$ (1-MCP), while the other treatment was left at $0^{\circ}C$ (control). They were packaged with $30{\mu}m$ oriented polypropylene (OPP, $1238.0cc/m^2{\cdot}day{\cdot}atm\;O_2$), and microperforated (MP3, $3179.9cc/m^2{\cdot}day{\cdot}atm\;O_2$) film. Quality and sensory evaluation parameters of weight loss, stem firmness, skin color, off-flavor, overall quality were monitored after 3, and 4 weeks storage at $0^{\circ}C$ and plus 3 days on the shelf at room temperature. 1-MCP treated mushroom packaged with MP3 film kept 3.6~10.9% $O_2$ and 9.0~13.3% $CO_2$ concentration in the bag during storage, and showed high overall quality at 4 weeks storage at $0^{\circ}C$ + 3 days on the shelf at room temperature because of the lowest development of off-flavor, stem discoloration, and cap softening among the treatments.

  • Flammulina velutipes, known as winter mushroom or Enokitake, is an important edible mushroom in Korea. In 2017, approximately 28,000 tons of this mushroom were produced in Korea, putting its output at the third place, behind the oyster and king oyster mushrooms. Despite its high production, F. velutipes has the lowest distribution rate of domestic cultivars, estimated to be about 28 percent. To increase the income of farms and provide more options to consumers, we developed a new golden domestic cultivar 'Auram'. 'Auram' was bred by mating two monokaryotic strains isolated from ASI 4103 and ASI 4111. Auram has bright golden, hemispheric shaped caps, and light brown stipes, making it strikingly different from the control. The optimum mycelial growth temperature was 25℃, but Auram mostly displayed higher mycelial growth than the control in a wide range of temperatures. The yield of Auram (257.4 ± 13.5 g) was high, and the period of fruit body growth was also a couple of days ahead in bottle cultivation, compared with the control. Auram received a more favorable evaluation from farms and distributors than the control for its appearance, because the fruit body of Auram had an attractive golden color, and the spotted cap often seen in the control was not observed.

  • The Goryeo roof tiles from the Oegol site in Tangjeong, Asan are classified into three groups in color such as gray, red yellow and gray-yellow groups, respectively. While each group of tiles shows characteristic specific gravity, absorption ratio, LOI and vitrification degree, mineral content and distribution, and chemical composition are generally homogeneous among all groups of roof tiles. Also, all roof tiles and soils from the site show similar geochemical behavior of elements and clay-mineralization degree. This indicates that the soil from the site is probable to be a raw material of the roof tiles. Firing temperature of the roof tiles is estimated as 950 to $1,050^{\circ}C$ for the gray group, 800 to $900^{\circ}C$ for the red yellow group, and 900 to $950^{\circ}C$ for the gray-yellow group. In conclusion, roof tiles from the Oegol site is interpreted to be made of local clay without additive minerals, applying various firing conditions and standardized purifying process of raw clay materials.

  • The purpose of this study was to understand and improve the clothing habits and the apparel industry of North Korea in preparation for the reunification of South and North Korea. For this study, literary data, reports, periodicals, interviews and internet data of the two Koreas were reviewed. North Korean clothing habits used to be monotonous and uniform but nowadays people's clothes have become somewhat brighter in color and more diverse in design than before. In particular, liberal and individual dressing habits appeared among the privileged classes. When taking part in national events, women have to wear the traditional Korean costume, Hanbok, while men wear business suits for formal wear. In general, men don't wear Hanbok. Students have to be in uniforms but blue jeans, T-shirts with English logos were popular among them reflecting their sensitivity and openness towards western cultures. The brides usually wear pink Hanboks and the bridegrooms wear black business suits for their wedding. North Koreans also wear Hanbok on national holidays like South Koreans. Clothing is the most important item in the trade of process commission between North and South Korea. Trading items are mid to low end men's clothing for the most part due to less emphasis on fashion in the North. The processing is indirect trade and composed of sample making and contracting, sending out materials and production, carrying in goods and setting accounts. To activate South-North trade, establishment of infrastructure, stabilization of shipping, reducing high costs of distribution, building direct communication system by setting up office in a neutral zone and simplifying procedures in applying for the South and North Korea Economic Cooperation Fund. On the other hand, clothing and textiles education is carried on at art colleges, light industries colleges and commercial colleges in Pyongyang. Clothing institutes which study Hanbok and Western clothes, are installed in each city and province. Graduates who majored in clothing and textiles are posted in institutes or apparel factories. Their job is designing, patternmaking and sewing for their customers. Most of them are women and in good state of economic conditions. The North Korean clothing industry has been the core national industry that has developed based on overseas demand form the mid 1980s. The standard is that of South Korea in the early 1980s. In 1999, trade of North Korean textile products with trade counterparts such as Japan and China was $1.3 million in exports and $1.27 in imports. Of this amount the export takes up 25.4% of the total exports in North Korea. However, fundamentally even in sectors that are irrelevant to politics such as the fashion clothing industry, trust between the South and North should be a prerequisite. Only through this can exchange between North and South and economic cooperation contribute towards the reunification.

  • The Andong pluton in the Andong Batholith is composed of comagmatic plutonic rocks, in which the lithofacies comprise hornblende biotite tonalite in the central paft biotite granodiorite in the marginal paft and porphyritic biotite granite at the topside (noJthea~tern paft) of the pluton. The pluton is petrographically and petrochemically zoned, having more mafic center than margin and topside. Distribution pallern of the lithofacies represents a reverse zoning in the pluton. Modal and chemical data in the pluton show progressive and gradual compositional variations from the centrer via the margin to the topside. Quartz and K-teldspar increase toward the topside of the pluton, whereas hornblende, biotite and color index increase toward the center. The bulk composition in the pluton is also reversely zoned, with high $Si0_2$ and $K_{2}O$ in the topside facies, and high MnO, CaO, $Ti0_2$, $Fe_{2}O_{3}$t, MgO and $P_{2}O_{5}$ in the central facies. The reverse zoning is also evident in higher Cr. V, Ni, Sc and Sr of the more mafic tonalite in the interior. The reversely zoned pluton results from remobilization (resurgence) of the lower more mafic compositional zone into the upper more felsic zones of the pluton modified by thennogravitational diffusion and fractional crystallization. In the initial stages of evolution, the pluton was a petrochemical system that fonned chemical compositional zonation with mafic tonalitic magma in the lower. granodioritic one in the middle and granitic one in the upper paft of the magma chamber. Periodic influxes of more mafic magma from the ba~e resulted in mingling of liquids and redistribution of minerals, and may have triggered the remobilil.ation of the lower compositional zone into the upper more felsic zones.
