Two strains Pleurotus eryngii KNR2312 and A8B10 (Na) which have good traits in cap quality and speedy growing were selected to breed a new strain carrying the two traits. KNR2312-2636-$10{\times}18$ (Ga) with 45.2 cap lightness and 6.5 quality was breeded by a consecutive inbreeding between KNR2312-derived monokaryons. $Ga5{\times}Na5$ came from outcrossing between Ga and Na was backcrossed with KNR2312-derived monokaryons twice to improve quality in cap color and shape. Therethrough Ga5NaKNR2312-47KNR2312-$12{\times}38$ carrying lightness of 49.5, quality of 7.3 and weight of 95.1 g was selected. The selected strain possesses good quality and dark color of cap. Especially its edge is 24 mm thick, therefore it is not likely damaged during processing and distribution.

Architecture framework (AF) is a guideline to define components needed to develop and operate enterprise architecture (EA), and to define relationships among the components. There are many architecture frameworks to operate EA of governments and businesses such as Zachman framework, DoDAF, TOGAF, FEAF, and TEAF. DoDAF is the most representative AF to support the development of the EA in the military domain. DoDAF is composed of eight viewpoints and 40 views that are affiliated with the viewpoints. To develop an AF for a specific goal, system architects decide a set of views. Furthermore, they determine data that are needed for a view modeling. However, views and data in DoDAF are structurally inter-related explicitly and/or implicitly. So, developing an AF for a specific goal is going to be a project to be carried out over a long haul. To reduce the burden of its development, in this paper, we develop ONT-SAF (Ontology for DoDAF) that can infer inter-relationships like referential and transitive relationships and the sequences among the views. Furthermore, to promote reusability and consistency of the views and the data within an AF, we adopt the view-data separation strategy. ONT-DAT contains classes like 'viewpoint', 'view', 'data', 'expression method', and 'reference model', and 11 properties including 'hasView.' To prove the effectiveness of ONT-SAF, we perform a case study.

In this study, 195 pesticide residues in fruit samples (n=150) at local markets in Chungcheongnam-do Chungnam, Korea were monitored using a multi-residue method combined with GC-MS/MS and LCMS/MS. Among 150 fruit samples, 40 types of pesticides were detected in 63 samples and the detection rate was 42.0%. However, the amounts were below the maximum residue limit (MRL). Detection rates for pesticides in each thpe of fruit were as follows ; citrus fruits (55.2%), pome fruits (41.3%), berries (38.7%) and stone fruits (36.0%). Although the sample size was small (n=2), pesticide residues were not detected in tropical fruits. Occurrences of detection of pesticide residues in apple showed the highest level, and mainly, insecticides were detected most frequently. The most commonly detected pesticides residues were bifenthrin (21), pyraclostrobin (17), novaluron (13), boscalid (10), chlorfenapyr (9), trifloxystrobin (9), furathiocarb (9), acetamiprid (8) and chlorpyrifos (8). Five types of residual pesticides (bifenthrin, chlorfenapyr, deltamethrin, fenpropathrin and fenvalerate) were detected in quince, and out of these five, fenpropathrin exceeded the MRL based on the Positive List System (PLS). These results suggested that pesticide residues in fruit samples should be continuously monitored, although residue levels in 63 other fruit samples were evaluated as being within a safe level.

The aim of this study was to examine the metabolic adjustment of lactate dehydrogenase (EC 1.1.1.27, LDH) isozymes to a change in dissolved oxygen (DO) in bluegill (Lepomis macrochirus). After bluegills were adapted to a constant environment in an aquarium, the DO was changed to investigate the activity of LDH isozyme and the relative ratio of subunits A, B, and C for each tissue. When the DO was decreased from 18 ppm to 6 ppm, LDH in skeletal muscle, heart, and brain tissues recovered to the level of control activity within 12, 12, and 6 hr, respectively. LDH activity changed in accordance with a change in DO. The compensation was performed rapidly and is thought to be an important function of LDH in enabling bluegills to adapt to their environment. In bluegill heart, eye, and brain tissues, the relative ratio of subunit A increased and showed a tendency to recover similarly to the subunit ratio of control groups up to 12 hr. It is thought that the anaerobic metabolism using subunit A was increased in the initial stage when DO was changed. In addition, the results revealed that subunit C was more similar to subunit A than subunit B. In bluegills, subunits A and C of LDH seem to be evolutionarily similar. LDH isozymes, mainly containing subunits A and C, are likely responsible for the function of pyruvate reductase, which plays a role in making the bluegill adapt to a hypoxic environment through anaerobic metabolism.

Most of the current administrative names and locations for the names of places in the Nanjung diary have since been confirmed. However, a disagreement ensued among translators or researchers over Anpyeon-do (Baleum-do) islet recorded in Admiral Yi Sun-Shin's diary. Anpyeon-do was first recorded in the diary on October 11, 1597. It is credited to be the location where Yi Sun-shin and Chosun Naval Fleet stayed when sailing along the Southwestern coast of the Korean Peninsula after the battle of Myeongnyang. However, Anpyeon-do's exact geographical location has never been accurately confirmed. To accurately locate the islet, this study compared the direction and position of geographical locations observed in the Anpeon-do site match to actual geographical positions and directions. In addition, the direction and position of the geographical locations observed in the newly explored islands and mountains were evaluated with regard to how they correspond to the actual Anpeon-do. As a result, we concluded that the real location of Anpyeon-do recorded in the Nanjung diary is the Maebong mountain in Anjwa-do.

This study is aimed at researching Gyobang Dance performed by gisaeng of Gyobang in the banquet of Tonshinsa in Yeongnam Jwa-do Province. For this study, Hae-haeng-chong-che, a collection of 28 travel essays written by Joseon Tonshinsa after visiting Japan, and a collection of literary works were analyzed. Joseon Tonshinsa used Yeongnam Jwa-do Province as a route to Japan in obedience to a royal command, and Yeongnam U-do Province as a way back to Hanyang after completing their missions. The country gave a huge banquet to relieve Tonshinsa's anxiety about the voyage and to pray for a safe trip. The banquets were concentrated in Yeongnam Jwa-do Province, the way down to Busan departing from Hanyang. Looking into Tonshinsa's records, it can be seen that Tonshinsa banquets took place in Andong, Yeongcheon, Gyeongju, Milyang, and Busan. Gyobang Dance performed at Tonshinsa banquets includes Geommu, Hwangchangmu, Cheoyongmu, Cheondo, Mudong, Ipchum, and Jungchum. Through Tonshinsa envoy, 'Jeseon Tonshinsa-gil' was formed in Yeongnam Jwa-do Province, and through Tonshinsa banquets, the artistry of Gyobang Dance was compiled. Nevertheless, present Yeongnam Jwa-do Province has remarkably less Gyobang Dance passed down in comparison to Yeongnam U-do Province. For this reason, there is a need to look into Gyobang Dance of Yeongnam Jwa-do Province. The purpose of this study is to closely examine the cultural and artistic characteristics of Gyobang Dance performed at Tonshinsa banquets in Yeongnam Jwa-do Province formed through Joseon Tonshinsa-gil.

This research was conducted to investigate the influence of application rate of liming fertilizers on changes in soil chemical properties and growth of 'Red Madness' petunia in plug production. To achieve this, dolomite (DO) with 0, 1.0, 3.5, 8.0 or 13.0 $g{\cdot}L^{-1}$ and calcium carbonate (CC) with 0, 2.0, 2.5, 3.0, 3.5, or 4.0 $g{\cdot}L^{-1}$ were incorporated into peatmoss + vermiculite (1:1, v/v) during the root substrates formulation. The treatments of 3.5 $g{\cdot}L^{-1}$ of DO and 2.5 or 3.0 $gL^{-1}$ of CC had acceptable ranges of pH and EC in soil solution such as 5.6~6.2 and 0.7~1.0 $dS{\cdot}m^{-1}$, respectively. The faster rising of pH was observed in root media containing CC rather than those of DO. This indicates that the solubility of CC is higher than DO. The soil Ca concentrations in all treatments of CC were 1.8 times as high as those of DO. The treatments of 3.5 or 8.0 $g{\cdot}L^{-1}$ of DO had the highest soil Mg concentrations, but all treatments of CC had lower soil Mg concentrations than control treatment indicating that additional application of Mg fertilizers are required. The elevated application rate of DO or CC resulted in the increase of fresh and dry weight. But plant heights were not influenced by application of liming fertilizers. The results of tissue analysis showed that application of DO or CC influenced the $PO_4{^-}P$, Ca and Mg contents, but not influenced the contents of other nutrients such as N, P, Fe, Mn, Zn and Cu.

Objectives: The concentrations and distribution characteristics of volatile organic compounds (VOCs) in an industrial complex and surrouding affected residential areas were investigated in an effort to support the efficient management of VOCs. Methods: The atmospheric concentrations of VOCs were analyzed at sites around the Sihwa-Banwol complex located in the cities of Siheung and Ansan and in the surrounding affected residential areas. The appearance of VOCs and the characteristics of their temporal and spatial distribution were evaluated. Results: The total VOC concentrations in the industrial complex were detected at 1.9-2.3 times higher than in the affected areas, but the daily VOCs distributions showed similar patterns in both sites. In particular, it was confirmed that the composition ratio of the VOCs and concentration fluctuations over time in the affected areas are similar to those in the adjacent industrial complex. VOC levels in the affected areas were higher than in residential areas in cities without an industrial complex. Conclusions: VOCs in residential areas near an industrial complex were highly distributed due to the influence of continuous pollutant emissions from the industrial complex. Therefore, the management of VOCs in the atmosphere of the affected area is important for identifying and managing the sources of VOCs detected in high concentrations in the industrial complex.

Purpose - In order for actively pursuing medium and long term policies of Gangwon region to be effectively and efficiently driven, efficacious and practical development strategies are needed. In terms of regional revitalization in most regions that are dependent on the primary industry like Gangwon-do Province, the maintaining of local community becomes difficult and there are limitations on the support from the central government and local governments. Therefore, local communities need to implement measures not only to be financially independent but also maintain and activate themselves. And community business can be adopted to be a proper strategy to cope with this change. This study drew importance of a community business model appropriate for Gangwon-do region to figure out success factors. Research design, data, and methodology - This study aimed to come up with importance of community business model for Gangwon-do region by using AHP Method. AHP Method, which was developed by Professor Saaty in 1970', is a methodology to simplify complex problems for a rational decision making. A survey targeting related public officials and expert group was carried out and a total of 30 questionnaires were collected for the analysis. Results - Analysis model used in this study was to prioritize community business models of Gangwon-do region. The second hierarchy was divided according to local restoration type, local resource utilization type, environment improvement type, and life support type. The third hierarchy consisted of 5 items such as network, the middle structure, program, government support, and human resources to measure each importance. As a result, in the second hierarchy, local resource utilization type had the highest importance. In the third hierarchy, the middle structure had the highest importance, followed by government support, program, network, and human resources. Collectively, the results suggested that important critical factors of community business model of Gangwon-do region was the importance of local resource utilization model and the middle structure. Conclusions - Not only should projects that are already operating in the region but next community business projects that are planning in the Gangwon-do region should be practically operated in view of the importance and the models derived from this study.
