Background: Isolation of M. tuberculosis (MTB) is required in cases of Tuberculous pleural effusion (TBPE) for confirming diagnosis and successful therapy based on drug sensitivity test. Several studies have focused on predictors of MTB culture positivity in TBPE. However, the clinical role of loculated TBPE as a predictor of MTB cultivation from TBPE remains unclear. The aim of this study was to examine possible predictors including loculation of TBPE of MTB culture positivity in TBPE. Methods: We retrospectively examined associations between clinical, radiological, microbiological, and laboratory characteristics and positive MTB culture from TBPE to determine a potent predictor of culture positivity. Results: From January 2011 to August 2015, 232 patients with TBPE were identified. Of these, 219 were finally analyzed. Among them, 69 (31.5%) were culture positive for MTB in TBPE and 86 (39.3%) had loculated TBPE. In multivariate logistic regression analysis, the loculation of TBPE was independently associated with culture positivity for MTB in TBPE (adjusted odds ratio [OR], 40.062; 95% confidence interval [CI], 9.355-171.556; p<0.001). In contrast, the lymphocyte percentage of TBPE (adjusted OR, 0.934; 95% CI, 0.899-0.971; p=0.001) was inversely associated with culture positivity for MTB in TBPE. Conclusion: In clinical practice, identification of loculation in TBPE is easy, reliable to measure, not uncommon and may be helpful to predict the possibility of positive mycobacterial culture.

Newly introduced two lines of apios (Apios americana Medikus, red-vine and green-vine) were grown in Jeju island, to clarify their growth and production characteristics as well as to develope as a new edible crops in Korea. Both lines bloomed but did not develop to pod and seed. The red-viny line showed the habit of more early growth and maturity compared with green-viny line. Fresh tuber yields per 10a harvested in late November ranged from about 500kg to 800kg as according to the lines and cultural condition. Fresh tuber yield of red-viny line was relatively greater than that of green-viny line, mainly due to their higher tuber number per plant. Among the planting dates(April 1, April 16 and May 1) of seed tubes, highest tuber yield was obtained on May 16 planting. And the stacking cultivation culture was better than non-stacking cultivation in respect of tuber yield and disease avoidance. These results indicate that apios can produce in Jeju island, and in order to extend its cultivation to farmers it will be needed to develope some cultivars with high yields as well as labor-saving cultivation methods.

Jeju Island is located at a strategic position, making it an important waypoint on the sea routes of East Asia. As a result, the island suffered many foreign invasions throughout history. Especially, it is widely known that Japanese pirates frequently invaded the island as the island was located on their way as they were sailing to China. Therefore, they built various defensive structures across the island. Fortresses, where a small number of defenders may fend off an enemy, were built in multiple places on the island. This was a strategy for the island to defend itself, as it was almost impossible to get prompt support in an emergency from the mainland due to the long distance. Fortresses, or walled cities, were the center of politics, culture, and economy of many areas. Therefore, they are a valuable resource to study the history and geographical characteristics of a place. For this reason, studies on fortresses started quite early on. However, studies on such relics in Jeju Island began very late. The research on fortresses was launched during the Japanese occupation for most mainland areas. However, studies on the relics on Jeju Island began as late as the 1970s. This was because scholars did not understand the importance of the city walls and fortresses on Jeju Island, and there were no researchers who specialized in city walls or fortresses on the island, as well. As archeological research on Jeju Island began to gain momentum, the studies on city walls and fortresses saw progress; however, these studies are still of an elementary level. In this study, the author summarized the status of studies on the city walls and fortress relics in Jeju Island and their preservation/maintenance status by era. According to the findings of this study, there were two Corean-era city wall/fortress relics and thirteen from the Chosun era., The researcher analyzed and presented the status of studies and the current condition of the relics. The status of attached structures was also documented.Furthermore, a short review of the maintenance work performed so far was provided. Also, the researcher mentioned the problems that accompanied the maintenance process of these relics, along with suggestions for improvement that could be referred to in future restoration/maintenance projects.

A Beoseonbongip is a pouch that holds patterns for making Beoseons. This study aimed to identify the aesthetic and symbolic contents of the embroidery patterns by analyzing the kind, combination types, expression and arrangement types of patterns. In total, 140 Beoseonbongip artifacts, which were mostly made in the Joseon Dynasty, were quantitatively and qualitatively analyzed. The results indicated that about 83% of the total had flower patterns. Various kinds of embroidery patterns used for Beoseonbongips were newly identified. About 73% of the total had different kinds of patterns. Pattern combination types were identified by the kinds of patterns, the number of paired patterns, and the traditional painting styles used. The patterns of Beoseonbongips were expressed schematically more than realistically or abstractly. Beoseonbongips with different patterns on the four triangle tips of the front face and Beoseonbongips with the same/similar patterns on two opposite tips of the front face were observed more than the other types. On the back face, the embroidery patterns were symmetrically arranged, showing various division structures. It was inferred that wishes (e.g., marital harmony, fertility, good health and longevity, happiness, and wealth and fame) were expressed through the symbolic patterns embroidered on the Beoseonbongips. In terms of Korean traditional beauty, the union with nature, the harmony of yin and yang, symmetric balance, and neatness were also emphasized as a esthetic characteristics of Beoseonbongips.

The objective of this research is to study on the analysis of long-term performance characteristics of various solar thermal system for heating protected horticulture system for reducing heating cost, increasing the value of product by environment control, and developing advanced culture technology by deploying solar thermal system. Long term field test for the demonstration was carried out in horticulture complex in Jeju Island. Reliability and economic aspect of the system which was operated complementary with thermal storage and solar hot water generation were analyzed by investigating collector efficiency, operation performance, and control features. Optimum operating condition and its characteristics were closely investigated by changing the control condition based on the temperature difference which is the most important operating parameter. However, it is expected that, in high-insolation areas where large-scale ground storage is adaptable, solar system demonstrated in the research could be economically competitive and promisingly disseminate over various application areas.

In this study, the dyeing of Chrysanthemum indicum Linne alone and the combined dyeing of Chrysanthemum indicum Linne and onion shell were first performed to compare dyeing properties. A combination extract of Chrysanthemum indicum Linne and onion shell can be expected to improve coloration. A Hanbok design for children used a natural dyeing fashion dyeing method to make the Chrysanthemum pattern. Chrysanthemum indicum Linne is a type of wild chrysanthemum with various medicinal effects for headache and stress relief, skin diseases, insomnia and depression. Widely used onion shells have medicinal properties that help prevent and treat various adult diseases. The colors of silk dyed exclusively by Chrysanthemum indicum Linne, and the colors of silk dyed by Chrysanthemum indicum Linne and onion shell extract are yellow; in addition, silk dyed by Chrysanthemum indicum Linne and onion shell extracts were almost all unchanged. Four hanboks, which are comfortable for children to wear and use, were produced using Chrysanthemum indicum Linne and onion shell extracts. If children wear hanbok fashion products with auspicious patterns, they can provide a chance to simultaneously experience the traditional symbolism of Korean patterns and culture. In addition, it is expected to develop pride in traditional dress culture.

The three endophytes, Blastophysa rhizopus, Bolbocoleon piliferum, Ulvella leptochaete, were isolated in a laboratory culture from a Grateloupia lanceolata thallus collected in Jeju. Effects of temperature and irradiance on growth and infection of the three species, were examined. Based on the unialgal cultures, their growth was examined under six temperatures (9, 13, 17, 21, 25, $29^{\circ}C$) and two irradiance levels (60, $100{\mu}mol\;m^{-2}s^{-1}$). Also, infection experiments to the five hosts (Ulva intestinalis, Scytosiphon lomentaria, Gracilaria verimiculophylla, Chondrus ocellatus, and Grateloupia elliptica) with three endophytes were carried out under four temperatures (10, 15, 20, $25^{\circ}C$) and two irradiance levels (60, $100{\mu}mol\;m^{-2}s^{-1}$). In culture of the endophytes, optimum growth was found in $100{\mu}mol\;m^{-2}s^{-1}$ in combination with $21^{\circ}C$. At the end of infection experiment, endophytes were observed at all the hosts. Among three endophytes, U. leptochaete was the most common at the five hosts. However, we did not observe any endophytes at all hosts tested under $10^{\circ}C$ condition. Based on this result, it appears that temperature acts as a limiting factor to infection of the three species.

This study evaluated the composition two popular species of edible bamboo shoots in Korea (Phyllostachyspubescens and Sinoarundinarianigra) and the effect of their abundant dietary fiber on intestinal microorganisms in healthy young women. The ranges of total moisture, crude protein, crude lipid, crude ash, and dietary fiber content were 87.190.8, 2.943.5, 0.150.39, 0.411.05, and 4.206.15% (wet weight basis), respectively. Moisture and crude ash content increased after heat treatment; however, crude protein, crude lipid, and dietary fiber content were reduced after heating. The major minerals found in bamboo shoots were potassium, phosphorous, sulfur, magnesium, and calcium. In addition, glucose and fructose were abundant free sugars, while asparagine and tyrosine were the most abundant free amino acids. Approximately 70% of the total free fatty acids found in bamboo shoots were linoleic acid and linolenic acid. The ascorbic acid content was 6.60~17.56 mg/100 g (wet weight basis), and one phenolic compound, p-hydroxy benzoic acid, was 0.10.2% (wet weight basis) and detected by HPLC analysis. The intake of bamboo shoots for seven days significantly increased viable cell counts of Lactobacillus spp. and reduced viable cell counts of Bacteriodes spp. in feces (p<0.05). In our data, bamboo shoots may be useful in the food industry as high dietary fiber ingredients.

The purpose of this study is to prove an importance of systemic analysis paradigm to interpret fashion make-up. This research employed 'paradigm for interpretation of fashion make-up signs' theory to analyze data. This theory consists of three steps to interpret the meaning of a work: (1) recognition of form, (2) analysis of connotation meanings, and (3) analysis of symbolic meanings and communication. The results of this study were as follows. Jean Paul Gaultier's eye make-up uses a square pattern that mostly consists of the color black. He presents a Glam Rock image by using rimmed make-up that portrays an avant-garde and a nonmainstream culture. Jean Paul Gaultier's make-up was showing black color and square eye pattern and was presenting Glam Rock image and was a rimmed make-up meaning a nonmainstream culture and Avant-garde symbolically. Chanel's make-up emphasizes the eyehole with the rimmed technique by applying the make-up of Marchesa Casati and including non-popularity, Limited Marketing symbolically. Christian Dior's make-up applies the representative make-up of Joan of Arc and Siouxsie sioux and also uses rimmed make-up to portray the meaning of religion persecution, the dark-ages militarism and including Humanism symbolically.

Demand for organic agriculture has greatly increased in the past decade. The objective of this study was to evaluate quality the characteristics and antioxidant activities of organically and conventionally grown carrots. Organically and conventionally grown carrots were harvested in Jeju Island, Korea. Carrot extracts were investigated for their antioxidative components (total phenolic and flavonoid contents) and their antioxidant activities (DPPH and ABTS radical scavenging activities). The quality characteristics of carrots were estimated in terms of hardness, length, weight, moisture contents, and soluble solid content (SSC). Conventionally grown carrots showed higher values than organic carrot in terms of hardness (p<0.05), but there was no significant difference in moisture contents or SSC. In the case of antioxidant activity, organic carrots showed a higher value for DPPH radical scavenging activity (p<0.05). However, there was no significant difference in other antioxidants. Consequently, quality characteristics and antioxidant activities were different between organically and conventionally grown carrots.
