This is an attempt to analyze original films of ChunHyang Jun that Shin Sang-Ok filmed in North and South Korea, focusing on the character of MongYong. These films were made during political transition periods of North and South Korea. Sung ChunHyang was made during the second republic of South Korea, which was established after the collapse of Rhee SyngMan government; and Love, Love, My Love was made in North Korea during the period of power transfer from Kim Il-Sung to Kim Jong-Un. Considering these political changes, the character of MongYong seems to represent the figure of authority North and South Korean society of the time had in mind. First, MongYong in Sung ChunHyang has a strong image of a lover who repays ChunHyang's devotion and sacrifice with romantic affection. As an authoritative figure, he has the aspect of a democratic leader or mediator. On the other hand, MongYong's image in Love, Love, My Love is a heroic authority figure of the revolutionary class. He is a subversive reformer who shows love for the people and treats them favorably, gaining public desire. This research is expected to inspire more studies on the meanings of hit movies based on classic literature under synchronic terms.

Jujube tree farms need effective methods of pest control to reduce damage caused by mirid bugs. In this study, we measured the density of mirid bug populations in jujube trees and tested the efficacy of various insecticides. We observed seasonal density patterns, where nymphs were observed from early May to the middle of July; and adults were observed from the end of May to the middle or end of July. Furthermore, we measured the density of two types of mirid bug species, Apolygus spinolae and A. lucorum. Among 45 damaged jujube trees, the dominant species of mirid bugs was A. spinolae (89%). We tested 7 types of insecticides to control mirid bug populations, including pyrifluquinazon, deltamethrin, diazinon, dinotefuran, etofenprox, fenitrothion, and bifenthrin, showing over 80% efficacy. Thus, in this study, we showed that using insecticides was effective for controlling mirid bug populations on jujube trees.

To understand vegetational characteristics of abandoned paddy terraces (APTs), species composition and plant species richness of APTs were compared with those of other natural- and constructed wetlands (NWs and CWs, respectively). Based on frequency of major vegetational components, Phragmites japonicus was more common in APTs (23.9%) than NWs (10.8%) and CWs (10.8%), whereas P. australis was less frequent in APTs (18.3%) than NWs (43.1%) and CWs (35.4%). Typha orientalis was common only in APTs (19.7%), whereas T. angustifolia was relatively common in NWs (21.5%) and CWs (32.3%). In addition, some wetland obligate species such as Leersia japonica, Oenanthe javanica, and Sium suave were frequently found only in APTs. In particular, APTs showed higher plant species richness ($6.3{\pm}2.2\;species/m^2$) than NWs ($4.9{\pm}1.8\;species/m^2$) and CWs ($3.9{\pm}1.3\;species/m^2$). APTs exhibited not only their distinctive vegetational characteristics but also higher ecological value in terms of plant species richness. Further attention on APTs as valuable biotopes supporting diverse plant species and continuous effort for management and conservation are needed more.

The elderly often produce irrelevant speech and get off-topic more easily than the young; the former also has difficulty generating fewer syntactic structures and makes errors of grammatical morphemes. In particular, the elderly might have more difficulty writing since it requires more complex cognitive processes than storytelling. The participants in this study were 32 young people and 32 older people. They were asked to write a short story of Korean fairy tale('Heungbu Nolbu'). The data was analyzed in narrative composition and syntactic structures. The study revealed the following: First, in composition aspects, the elderly group showed significantly lower total number of story grammar and episodes. In addition, the elderly produced more off topic statements. Second, in syntactic aspects, although there was no significant difference in the number of producing complex sentences between two groups, the elderly group generated more inadequate cohesive devices and used fewer relative and adverbial clauses. These findings suggest that the elderly have a tendency to perform tasks by producing more off-topic statements and shows decreasing coherence by using lower number of relative and adverbial clauses. However, this study also uncovers that the elderly were able to write more complex and longer sentences using visual feedback.

Vegetation and water characteristics of an eco-technological water purifying biotope were investigated at five years after the wetland construction. A total of 91 vascular plant species in 36 families were recorded. Initially planted emergent macrophytes such as Phragmites australis, P. japonicus, Zizania latifolia, Typha latifolia, and T. angustifolia mainly comprised the vegetational components of the wetland. The effect of water purification was observed markedly in most indicators such as electric conductivity (P < 0.01), $NO_3-N$ (P < 0.05), $NH_4-N$ (P < 0.001), $K^+$ (P < 0.05), $Na^+$ (P < 0.01), and $Mg^{2+}$ (P < 0.01). In particular, $NO_3-N$ and $NH_4-N$ concentrations decreased to about 60% and 30%, respectively, via the purification process of the wetland. Separativeness and curvature from the meandering structure of 15 units (multi-cell wetland system) seemed likely to make the wetland continuously play a role as an eco-technological water purifying biotope. We recommend that eco-technological design factors should be included in wetland constructions for efficient and continuous functioning, thus enhancing ecological values of wetlands.

Chinese jujube (Ziziphus jujuba Mill.), a member of family Rhamnaceae, is an economically important species. It has high nutritional value in fruits, and its medicinal properties have led to extensive use in traditional oriental medicine. In this study, we investigated the genetic characteristics of 270 jujube germplasms collected from the six major jujube fruit production areas in Korea including Boeun and Gyeongsan, in order to understand the current situation on cultivated varieties of domestic jujube and to obtain useful data for selection of superior germplasms and establishing their breeding plans. The results of ISSR marker analysis revealed that the Shannon's information index of the 270 germplasms was 0.107 and the genetic similarity was as high as 0.935 showing the dominance of a specific cultivar or germplasm, and almost 67% (180) of them were identified at the same genotype with 'Bokjo'. The domestic commercial jujube populations could be characterized by very low genetic diversity and thus may be vulnerable to external disturbances. In addition, it seems that most of the jujube fruits in domestic market were largely produced through parthenocarpy.

Precise and fast identification of crop cultivars is essential for efficient breeding and plant breeders' rights. Traditional methods for identification of jujube cultivars are based on the evaluation of morphological characteristics. However, due to time constraints and environmental influences, it is difficult to distinguish cultivars using only morphological traits. In this study, we cloned fragments from improved inter simple sequence repeats (ISSR) analysis, and developed stably diagnostic sequence-characterized amplified region (SCAR) markers. The specific ISSR bands of jujube cultivars from Dalizao and Boeundaechu were purified, cloned, and sequenced. As a result, four clones labeled 827Dalizao550, 827Boeun750, 846Boeun700, and 847Dalizao850 were identified. In order to investigate whether they were specific for the jujube cultivar, four pairs of SCAR primers were then designed and polymerase chain reaction (PCR) amplifications were conducted to analyze 32 samples, including jujube and sour jujube. In the PCR amplification of the 827Dalizao550 SCAR marker, the specific bands with 550 bp were amplified in six samples (Dalizao, Sandonglizao, Dongzao, Yuanlin No. 2, Suanzao 2, Suanzao 4), but unexpected bands (490 bp) were amplified in the others. Moreover, in the PCR amplification of the 847Dalizao850 SCAR marker, the specific bands with 850 bp were found in three samples (Dalizao, Sandonglizao, and Dongzao) and 900 bp unexpected bands were amplified in five samples (Pozao, Suanzao 1, Suanzao 2, Suanzao 3, Suanzao 4). These results showed that newly developed markers could be useful as a fast and reliable tool to identify jujube cultivars. However, further identification of polymorphic information and the development of SCAR markers are required for the identification of more diverse cultivars.

This study focused on understanding the Korean university students' (both undergraduates and graduates) use of foreign language for scholarly information retrieval especially in different search strategies employed based on users' characteristics. A new model was developed based on Ellis's behavioral model of information seeking strategies. The research applied both quantitative and qualitative methods to analyze the data. The students used a variety of foreign language information seeking strategies at different stages of academic information retrieval based on his/her field of study or level of education. The liberal arts and social science students had more difficulty in selecting proper search terms in the foreign language than the science and technology students. This difficulty resulted in less preference for using foreign language queries by the liberal arts and social science students. The students relied more on the bibliographic and citation information in scholarly information retrieval using foreign language queries than the Korean queries. The research outcomes should provide some guidelines on how the Korean university libraries offer information literacy programs and other services based on the patrons' characteristics.

The Purpose of this paper is, through the character-figuration aspect of existing Yeoheon Jang Hyungwang(旅軒 張顯光, 1554~1637)-related folk tales, to determine the relation between the people's awareness on Yeoheon and the change in the folk tales. Only 4 pieces of Yeoheon-related folk tales are existed ; ; Forgiving a rude son of the provincial governor generously. ; Predicting 'the frost of May' and Preventing the cold-weather damage, when he served as Euiseong governor, and ; The folk tales of origins of the place name - Chimabawi Rockand Yeoheondae. shows the great scholar's liberal-hearted and generous personality. One day Jang Hyungwang looked shabby and a young person was quite rude to him. But Jang Hyungwang forgive him generously. Also Yeoheon teach him the thrift and modesty. described him as a governor filled with a love for the people. He tried to edify the people with the Confucian ethics and improve the life's work of the people. embodied him as a government official of high integrity. When his wife received the silk slip from the people, as farewell gift, he ordered his wife return that. and show the images of the Predicting the future and an extraordinary moralizer. Generally These folk tales are based on his personality, whereabouts and the real case. So we could find his images in the folk tales are close to his actual feature - thrift, modest, noble-minded, well-versed in Iching and practicing moral statesmanship.

Purpose: This study was conducted to effectively apply the nutrition and hygiene education program for improving the nutritional status of the elderly aged 65 years and above. Methods: The first study was conducted by enrolling 121 willing elderly subjects from welfare centers in four regions of Chungbuk. The second study included 347 people from 10 regions of Chungbuk. Data were analyzed using the SPSS (version 12.0) and SAS (version 9.2) programs. Results: Most participants in both studies were women, ranging from 70-79 years of age. In the first study, the performance rates of subjects, after imparting the education on hygiene, eating habits, and nutritional knowledge, were significantly increased for all factors. Goesan and Boeun areas were highly effective in hygiene practice and eating habits after education. In the second study, Chungju had the most educational effect on hygiene education, with a score of 6.41 points before education and 7.68 points after education. The greatest impact of education on eating habits was obtained at Goesan, with 9.23 points and 11.26 points before and after education, respectively. Large regional differences were determined for the effect of the education program. For nutritional knowledge, the combined average score of Boeun and Goesan showed a maximum increase after education. When considering satisfaction, the scores of Cheongju and Jeungpyeong increased the most after education, whereas Goesan showed that the average scores before and after education were close to perfect. Surprisingly, the Okcheon area, where there was no significant difference in the educational effect after the education program in the first study, showed significant improvement for all factors after the second education program. The current study indicates that continuous education programs are essential for improving the nutritional status of the elderly. Conclusion: Therefore, continuous nutrition and hygiene education programs are recommended to improve the nutritional status of the elderly.
