Objectives : Gagam-Gongjin-dan (GGD) composited with Cervi parvum Cornu, Corni Fructus, Angelica gigantis Radix, Lycii Fructus, Dioscoreae Rhizoma, Citri Pericarpium, Gastrodiae Rihzoma, Agastachis Herba, Cassiae cortkex, Scutellariae Radix, Schisandrae Fructus has been traditionally used for chronic diseases or weakness after illness in oriental countries. However, little is known about the effects of methanol extract of GGD on immune responses to ovalbumin (OVA) plus alum. Therefore, the purpose of this study was to investigate the effects of GGD on immune responses to ovalbumin plus alum in Balb/c mice. Methods : In this study, the extract of GGD was prepared by extracting with methanol for 7 days. The extract was freeze-dried following filtration through vacuum distillation system. Mice were orally administrated with or without GGD extract of different doses (50-200 mg/kg/day) for 30 days. We examined the effects of GGD extract on the serum levels of total IgE, OVA-specific IgE, IgG1, IgG2a, and CTACK/CCL27 production and CCR10 expression in lymph node cells and body weight change and foot pad swelling responses in ovalbumin treated Balb/c. Results : The oral administration of GGD dose-dependently reduced the serum levels of total IgE, OVA-specific immunoglobulin (IgE, IgG1 and IgG2b) and CTACK/CCL27 production in ovalbumin treated BALB/c mice. The levels of CCR10 expression from lymph node cells of OVA treated mice were markedly suppressed by treatment with GGD in a concentration dependent manner. Furthermore, foot pad swelling responses were also markedly suppressed by GGD. However, body weight were significantly increased dose dependently by GGD treatment. Conclusions : These results suggest that GGD treatment suppresses immune responses to ovalbumin, and these properties may contribute to allergic disease care.

To obtain the basic information for late-cultivation of sweet potato [Ipomoea hatalas (L.) Lam. cv. 'Jinhongmi'], vine growth and storage root yield were investigated in variously cutting sizes (10, 20, and 30 cm) and planting depths (1~4 nodes in 30 cm vine) using black-film vinyl mulching cultivation ($75{\times}25\;cm$ planting density, June 20). At 30 days after planting, main vine length, number of node, and vine fresh weight were significantly affected by the cutting length, and these were significantly different 10 and 30 cm at 120 days. The vine elongation affected by planting depths showed the best growth in 2-nodes planting depth and the lowest growth in 4-nodes planting depth at 30 days, but the vine growth was not significantly different among planting depths at 120 days. Number of storage root per plant, weight of storage root per plant, mean weight of storage root and yield of storage root were increased in longer cutting length, and those in 10 cm cutting length were significantly reduced compared to the 20 and 30 cm cutting length. Number of storage root per plant in the deeper planting was much increased, but mean weight of storage root was much decreased. Yield of storage root per 10a was highest in 3-nodes planting depth. Therefore, planting methods by cutting length over 20 cm and planting depth of 2~3 nodes in late-cultivation of sweet potato will be more efficient to improve the vine growth and storage root yield.

This study was conducted to examine characteristics of rhizome growth and flowering of white lotus (Nelumbo nucifera) plant in Muan Hoesan-lake for collecting the basic data on the cultivation and the flowering which is growing in Muan Hoesan-lake of Jeonnam province in Korea. We have planted from the seeds and the enlarged rhizomes of the white lotus which were planted in the plastic containers on April 20 and May 4, 2008, and cultivated under rain shelter condition. Rhizome growth pattern and the flowering characteristics of the white lotus were examined on September 4, 2008. Main rhizomes of the white lotus propagated by the seeds and the enlarged rhizomes were branched by 10% and 15%, respectively. Numbers of nodes in the bloomed and non-bloomed rhizomes of the white lotus were over 14 and below 11, respectively. Flower was not observed in the white lotus when propagated with seeds, however, flowers came out up to 80% by the enlarged rhizomes. First flowers were bloomed from the late July and to the early August, and the number of flowers were 4.0~4.4. The first flower stalks without branching of the main rhizome were emerged in 8.8th node, however, that with branching were 8.0th node. Time to flowering from the emergence of flower stalk on the above-ground parts were required 16 days. White flowers from the lotus were 15.3 cm in height and 28.2 cm in width, their longevity was 3.3 days and the averaged flower fresh weight was 29.2 g. The results conclude that optimum number of nodes on the main rhizomes for blooming the white lotus flowers should be over 8 nodes before the rhizome enlargement.

This is descriptive study to 2nd analysis data KNHANES IV-VI about risk factors of readmission among patients with cardiovascular disease. Among the total 65,973 adults, 1,037 with angina or myocardial infarction were analyzed. The analysis was conducted using SPSS window 21 Program and CHAID decision tree was used in the classification analysis. Root nodes are economic activity(χ²=12.063, p=.001), children's nodes are personal income(χ²=6.575, p=.031), weight change(χ²=12.758, p=.001), residential area(χ²=4.025, p=.045), direct smoking(χ²=3.884, p=.031). p=.049), level of education(χ²=9.630, p=.024). Terminal nodes are hypertension(χ²=3.854, p=.050), diabetes mellitus(χ²=6.056, p=.014), occupation type(χ²=7.799, p=.037). We suggest that the development and operation of programs considering the integrated approach of various factors is necessary for the readmission management of cardiovascular patients.

Objectives : This study was to observe anticancer and related immunomodulatory effects of Kwibi-tang extracts (KBTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Methods : Three different dosages of KBTe, 50, 100 and 200 mg/kg were orally administered once a day for 42 days from 11 days after tumor cell inoculation. Six groups, each of 8 mice per group were used in the present study. Changes in body weight, tumor volume and weight, lymphatic organs (spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes NK cell activity and peritoneal macrophage activities, splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. The results were compared with a potent cytotoxic anticancer agent, 5-FU (5-Fluorouracil) 30 mg/kg, intraperitoneal treatment (3-day intervals for 42 days, the optimal effective treatment regimes already confirmed). Results & Conclusions : This study suggest that over 50 mg/kg of KBTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory effects. Although relatively lower anticancer effects were observed in KBTe 200 mg/kg treated mice as compared with 5-FU 30 mg/kg treated mice, no meaningful favorable immunomodulatory effects were observed after 5-FU treatment in the present study.

With the development of network and IT technology, people are searching and purchasing items they want, not bounded by places. Therefore, there are various studies on how to solve the scalability problem due to the rapidly increasing data in the recommendation system. In this paper, we propose an item-based collaborative filtering method using Tag weight and a recommendation technique using MapReduce method, which is a distributed parallel processing method. In order to improve speed and efficiency, the proposed method classifies items into categories in the preprocessing and groups according to the number of nodes. In each distributed node, data is processed by going through Map-Reduce step 4 times. In order to recommend better items to users, item tag weight is used in the similarity calculation. The experiment result indicated that the proposed method has been more enhanced the appropriacy compared to item-based method, and run efficiently on the large amounts of data.

This study investigated mechanical properties, drape coefficients and node indices of stretch fabrics. We applied mechanical properties to exhibited tailorability control in HESC and evaluated making-up. The mechanical properties such as tensile, bending, shearing, compression, surface characteristic values, thickness and weight were measured by the KES-F system and drape coefficient by drape tester. The summarized results of this study were as follows; First, stretch fabrics, almost, shown high stretch in weft inserted polyurethane yarn fabric and had a ${\pm}2{\sigma}$(sigma) range of shearing, compression, surface and thickness, except bending and weight, as compared with Japanese women's thin dress fabrics. Second, bending had a positive correlation in stiffness, anti-drape and flexibility & softness. Shearing had a negative correlation in crispness and scroop. Surface properties had a high contribution in fullness & softness. Third, The drape coefficient was found by measuring the mechanical properties according to the obtained regression equation. Forth, many problems are expected in overfeed and cutting operations in sewing process. In the decision of the good external appearance using TVA, only 26 of 55 samples are included in the range of the good external appearance. Fifth, in the regard of the result for sewing control, warp values are not necessary to control in the all kind of items. But weft value in the RT and EM are out of non-control zone. So we need a special management during sewing process.

Recently high utility pattern (HUP) mining is one of the most important research issuer in data mining since it can consider the different weight Haloes of items. However, existing mining algorithms suffer from the performance degradation because it cannot easily apply Apriori-principle for pattern mining. In this paper, we introduce new high utility pattern mining approach by using a prefix-tree as in FP-Growth algorithm. Our approach stores the weight value of each item into a node and utilizes them for pruning unnecessary patterns. We compare the performance characteristics of three different prefix-tree structures. By thorough experimentation, we also prove that our approach can give performance improvement to a degree.

The aim of this study was to identify the chronological growth characteristics of Gaeryangmeoru grapes, by observation of the developmental process of the axillary bud, fruit quality, and anatomical structure of the pericarp. No necrosis of axillary buds was observed, irrespective of node position of the shoot, from shoot occurrence to leaf fall. Berry weight, cluster weight, soluble solid content and titratable acidity were analyzed to be 1.2 g, 128.8 g, $16.9^{\circ}Brix$, and 1.57%, respectively, at maturity. The sugar was composed of fructose and glucose, with a ratio of 1:1 (fructose: glucose) at maturity. Malic acid was predominant among the organic acids, and conformed to the changes of chronological titratable acidity. Sugar and organic acid content changed dramatically starting a week before veraison. The degraded ovules were observed before and after fertilization, and the pericarp was composed of one epidermis, and seven to ten hypodermis layers at maturity.
