The purposes of this study were to investigate and understand the present status of various types of "deserts", such as sand desert, gravel desert, rock desert, earth desert, salt desert, desert, rocky desert, gobi desert, sandy desert, clay desert, etc., and the general countermeasures for the combating "desertification" "desertization", and to develop the technologies on the revegetation and restoration for the combating desertification in China. The methods of this study were mainly composed of field surveys on the several experimental sites and research institutes related to combating desertification in China, and examinations on the various technologies for the combating desertification at the Daxing Experimental Station of Beijing Forestry University. The conclusion from this study may be summarized as follows; 1. Status and tendency of desertification in China : China is one of the countries seriously threatened by desertification. Desertification affected areas in China are mainly distributed in arid, semi-arid and dry sub-humid areas in China, covering the most regions of the Northeast China (eastern region of Inner-Mongolia), the northern part of the North China (middle and western region of Inner-Mongolia, Shaanxi, Ningsha, Gansu) and the western part of the Northwest China (Xinzang, Qinghai, Xizang). The total area affected by desertification in China is approximately 2.622 million $km^2$. It covers 27.3% of the total territory of China. Until recently, it is estimated that the annual spreading ratio of desertification in China is 2,460 $km^2$. Therefore, desertification is mostly serious problems facing to the Chinese people. 2. The causes and environmental effect of desertification : The desertification in China is mainly caused by compound factors, including natural condition and human activities. In China, the desertification is started by the decrease of precipitation, continuous dry and drought, strong wind, wind and water erosion, land degradation and loss of natural vegetation caused by climate variation, and accelerated by the human activities, such as over-cultivating, over-grazing, over-cutting of woods, irrational use of water resources. Because desertification has affected the geographical features, soil nutrients contents, salinity, vegetation coverage and the functions of ecosystem, the environmental deteriorations in the desertification affected areas are very seriously. 3. The fundamental strategies of combating desertification in China are the increase of education and awareness of people through various mass media, the revision of laws to guarantee operation of Desertification Combating Law and to improve many relating laws and regulations, the application of advanced technologies and training of experts, the establishment of discriminative policies, and increasing arrangement of budget-investment, and so on. China, as a signed country in UNCCD, has made efforts for the combating desertification. Korea is also signed country in UNCCD, so we should play an important role in the desertification combating projects of China for the northest asia and global environmental conservation as well as environmental conservation of Korea.

We analyzed the movie (2016/ directed by J-yong E), which is entangled in politics of gender, age, class, or sexuality, naming as "spaces of Others", using the concepts of heterotopia of Foucault. Foucault addressed three types of spaces: the realistic space where we currently live, the unrealistic and non-existent utopia, and heterotopia, which functions antithetically to reality. Thus, Foucault's heterotopia can be considered to indicate "heterogeneous spaces" in reality. The Bacchus Lady revolves a 65-year old prostitute So-Young, sells her body to old men at the parks in downtown of Seoul. Old prostitute on streets are often referred as "Bacchus Ladies", because suggest the popular energy drink a bottle of Bacchus while selling sex. The movie represents some minorities such as transgender, Tina and madam of the club, G-spot, migrant women like Camila and Aindu, and a amputee, Dohoon. Through these people's bodies, the problems such as imperials, nations, ethnics, gender, age, class are entangled in the movie. The politics of these points work and construct heterotopias in four spaces of Others. First, the spaces which ageing and death are intersected. Second, the spaces of So-Young for prostitutes, Third, the spaces of So-Young's mothering: she adopted her baby to American when he was a infant, so she have felt guilty. Fourth, the spaces for So-young's quasi-family with Minho, a Kopian boy who was abandoned by Korean father, Dohoon, who is a poor amputee, and Tina, who is a transgender singer. Fifth, the spaces of speech of So-Young as the subaltern: the subaltern does not have the language to express its own experiences. In order to listen to the words of subaltern, we must do the task of measuring the silence. This cinematic representation of So-young as the subaltern makes her speak about her situation. Finally, the spaces constructed by the movie can be connected 'heterotopia of crisis', 'heterotopia of deviation' and 'heterotopia of fantasy'. The spaces of the movie represents lives of Others, nevertheless, So-Young's Otherness through spaces of heterotopia was transformed to an absolute Other by patriarchal traits of cinematic narrative.

I-cell disease (mucolipidosis type II; MIM 252500) and pseudo-Hurler polydystrophy (mucolipidosis type III; MIM 252600) are disorders caused by abnormal lysosomal transport in cells. The presence of numerous inclusion bodies in the cytoplasm of fibroblasts, a lack of mucopolysacchariduria, increased lysosomal enzyme activity in serum, and decreased GlcNAc-phosphotransferase activity are hallmark. Here, we attempted to investigate phenotypical and biochemical characteristics of the knockoutmouse of GlcNAc-phosphotransferase ${\alpha}/{\beta}$ subunits; in addition, we also attempted to determine whether the lysosome enriched fraction derived from placenta can be beneficial to phenotype and biochemistry of the knockout mouse.We found that the knockout mouse failed to thrive and had low bone density, as is the case in human. In addition, skin fibroblasts from the animal had the same biochemical characteristics, including increased lysosomal enzyme activity in the culture media, in contrast to the relatively low enzyme activity within the cells. Intravenous injection of the lysosome rich fraction derived from placenta into the tail vein of the animal resulted in a gain of weight, while saline injected animals didn't.In conclusion, our study demonstrated the phenotypical and biochemical similarities of the knockout mouse to a mucolipidosis type II patient and showed the therapeutic potential of the lysosome enriched fraction. We admit that a larger scale animal study will be needed; however, the disease model and the therapeutic potential of the lysosome enriched fraction will highlight the hope for a novel treatment approach to mucopolipidosis type II, for which no therapeutic modality is available.

The purpose of this study was to investigate the eating behavior, food preference and nutrition knowledge according to the body style of male college students. The subjects were 219 male students enrolled in University, Taegu. The data was collected by using a survey questionnaire and an anthropometric measurement. The results were summarized as follows: The mean height, weight and BMI of subjects were $173.8{\pm}8.7cm,\;65.8{\pm}7.9Kg,\;and\;21.9{\pm}2.4$, respectively. The subjects were divided into three groups according to the BMI: underweight group(<20); normal group(20-25); and overweight group(>25). One third of the subjects preferred to gain weight(33.8%); 47 subjects preferred to lose weight(21.5%); and the rest of the subjects satisfied their physique(44.7%). Most of subjects considered 'supper' as the most important meal during a day. Among the food items, the most frequently and evenly ingested item by subjects was 'Kimchi' : 'Ham and sausage' was the least preferred food among subjects. There was no significant difference in preference among three groups and almost half of the subjects had irregular meal time because of busy schedule. The preference for meat showed high score among underweight group; on the other hand, the preference for fruits and vegetables showed high score among overweight group. Usually subjects gained nutrition knowledge through media including newspaper, magazine and TV. There was no significant difference of the nutrition knowledge score among three groups. Based on these results, nutrition education program for the college student should be arranged in the classes.

The purpose of this study was to examine the awareness of dental hygienists in different regions about credit bank system and their needs for that. The subjects in this study were 312 dental hygienists in dental hospitals and clinics in Seoul, Gyeonggi province, metropolitan cities, Gangweon province and Gyeongsang province. After a survey was conducted in 2008, the collected data were analyzed with SPSS 11.5 program. The findings of the study were as follows: 1. In regard to perception of the credit bank system, 68.3 percent of the dental hygienists were cognizant of that. The dental hygienists from most of the geographic areas were aware of it, but all the forty three dental hygienists from Gangweon province who accounted for 13.8 percent didn't know about that. As for media by which they acquired information on that, many of the dental hygienists learned about it from their acquaintances (46.2%), but that was not the case for the dental hygienists from Seoul and Gyeonggi province. 2. As for expectations for the credit bank system, those from Gyeongsang province had the greatest expectations for that in six out of nine items, which included academic or job performance improvement, acquisition of credits, degree or certificates and access to new technology. 3. Concerning educational spending on the credit bank system, 18.9 percent and 8.7 percent from Seoul/Gyeonggi province and Gangweon province spent less than 30 thousand won, and 19.9 percent from the metropolitan cities spent 30 thousand to less than 50 thousand won. 4. As for the importance of the categories of their major in the credit bank system, those from Gangweon province attached the most importance to oral health education ($3.56{\pm}1.259$), and the dental hygienists from the metropolitan cities put the most stress on preventive treatment ($3.64{\pm}1.191$).

This study evaluated treatability of soluble Mn(II) using multifunctional sand media simultaneously coated with iron and manganese. In the preparation of IMCS(Iron and Manganese Coated Sand), 0.05 M Mn(II) solution and Fe(III) solution was mixed with sand at pH 7. The mineral type of IMCS was identified as the mixture of ${\gamma}-MnO_2$, goethite and magnetite($F_{e3}O_4$). The contents of Mn and Fe coated onto sand were 826 and 1676 mg/kg, respectively. The $pH_{pzc}$ of IMCS was measured as 6.40. The removal of soluble Mn(II) using IMCS and oxidants such as NaOCl and $KMnO_4$ was investigated with variation of the solution pH, reaction time and Mn(II) concentration in a batch test. The removal of Mn(II) on IMCS was 34% at pH 7.4 and the removals of Mn(II) on IMCS in the presence of NaOCl(13.6 mg/L) at pH 7 and $KMnO_4$(4.8 mg/L) at pH 7.6 were 96% and 89%, respectively. The removal of Mn(II) using IMCS and oxidants followed a typical cationic type, showing a gradual increase of removal as the solution pH increased. The removal of Mn(II) was rapid in the first 6 hrs and then a constant removal was observed. The maximum removed amount of Mn(II) on IMCS-alone and IMCS in the presence of oxidants such as NaOCl(13.6 mg/L) and $KMnO_4$(4.8mg/L) were 833.3, 1428.6 and 1666.7 mg/kg, respectively. Mn(II) removal onto the IMCS in the presence of oxidants was well described by second-order reaction and Langmuir isotherm expression.

In this study, iron and manganese coated sand (IMCS) was prepared by mixing Joomoonjin sand with solutions having different molar ratio of manganese ($Mn^{2+}$) and iron ($Fe^{3+}$). Mineral type of IMCS was analyzed by X-ray diffraction spectroscopy. Removal efficiency of arsenic through As(III) oxidation and As(V) adsorption by IMCS having different ratio of Mn/Fe was evaluated. The coated amount of total Mn and Fe on all IMCS samples was less than that on sand coated with iron-oxide alone (ICS) or manganese-oxide alone (MCS). The mineral type of the manganese oxide on MCS and iron oxides on ICS were identified as ${\gamma}-MnO_2$ and mixture of goethite and magnetite, respectively. The same mineral type was appeared on IMCS. Removed amount As(V) by IMCS was greatly affected by the content of Fe rather than by the content of Mn. Adsorption of As(V) by IMCS was little affected by the presence of monovalent and divalent electrolytes. However a greatly reduced As(V) adsorption as observed in the presence of trivalent electrolyte such as $PO_4\;^{3-}$. As(III) oxidation efficiency by MCS in the presence of NaCl or $NaNO_3$ was two times greater than that in the presence of $PO_4\;^{3-}$. Meanwhile a greater As(III) oxidation efficiency was observed by IMCS in the presence of $PO_4\;^{3-}$. This was explained by the competitive adsorption between phosphate and arsenate on the surface of IMCS.

Soundscapes have the potential to help people experience the historical background and cultural traditions by the scenery of a local area and to be used as a cultural and tourism resource. This concept was first explained in detail by M. Schafer and has been developed as a new way of experiencing landscapes using various senses. This research studied the soundscape of Kyodong Island, the so-called "Island of Peace" and designed new cultural acoustic content for education and tourism. Kyodong Island is located right below the Northern Limit Line and the whole island is in the Civilian Controlled Area. The political and economic status of the island has been changed dynamically by the Korean War and the division of the country. These days, the island needs to realize the vision of the "Island of Peace" in a more creative way using local resources, including its "cold war landscape" and the natural scenery of the region. This research applied the concept of a soundscape to document the island, and to reproduce it in an artistic way. A workshop was conducted to learn concepts and techniques of soundscapes with a sound artist. Listening, recording, conducting interviews, and literature research was used to study the soundscape of the island. After that, this research reconstructed the soundscape of the island through a soundscape composition. The main theme of the composition story was the "Hope and Wish for the Harmony and Peace" to show the vision of the "Island of Peace". The initial sub-theme for the introduction part was "First Encounter with Kyodong Island" arranging the representative soundscape, which could be the first impression of the region. The second sub-theme was "War and Tension" using several soundscapes as a metaphor for the tragedy of the Korean War. The third sub-theme was "Everyday Life of Kyodong Island" which described the energy of the present day, after the wounds of the war have healed. The final sub-theme was "Harmony and Peace" using traditional music and keynote sounds of the region as a reminder of the peaceful past, before the war. The recording files were documented as two types of sound maps. One was a two-dimensional map to show the soundscapes from one point of view, and the other used the online application called "Sound Around You". The final artwork was displayed at an exhibition and uploaded on YouTube to be shared publicly. Through this project, we discovered the potential of soundscapes as a medium to preserve the history and local identity, as well as presenting a new vision. The artwork will be exhibited at historically and culturally meaningful places on the Island to utilize the underused places as local tourist attractions and educational resources.

Gaeseong fostered the conditions necessary for modern capitalism, as huge capital was accumulated through the cultivation and trade of ginseng, which were activities that flourished in the 18th century. During the Japanese colonial era, ginseng merchants were not simply limited to acquiring landowner capital from ginseng trade but actively converted such resource to productive and financial capital, thereby becoming modern entrepreneurs. Ginseng merchants led the joint management and investment of Gaeseong Electric Co., Ltd., Daehan Cheonil Bank, Gaeseong Brewing Co., Ltd., and Songgo Textile Company, founded in the early 20th century. They pursued corporate profits and, as leading individuals of society, spearheaded regional development by supporting educational and cultural projects in Gaeseong. These projects included the establishment of the Gaeseong Commercial School, the publication of Goryeo Times, and the operation of the Gaeseong Jwa Theater. Although liberal economics prioritized shareholder interest, the 21st century witnessed an emphasis on social responsibility among stakeholders asthe major purpose of enterprises. A trend that emerged was ESG (environment, social, governance) management, in which non-financial factors are valued more highly than financial performance. A successful business, which was denoted only by high profits in the past, is now defined by whether a company fulfills its social responsibility. In the early 20th century, the corporate activities of ginseng merchants in Gaeseong reflected entrepreneurship and stakeholder-centered ESG management, which later emerged as essential elements of modern business management. The modern management philosophy ahead of its times stemmed from the regionality of Gaeseong. The political discrimination against Gaeseong residents in the Joseon Dynasty precluded them from becoming government officers, and under a strict social hierarchy, yangban ("noblemen"), the intellectuals of the Joseon Dynasty, were forced to serve as merchants. Son Bong-sang and Kong Seong-hak, aside from being representative ginseng merchants, were both Confucian scholars and writers. The second and third generations of ginseng merchant families who had received higher education abroad returned to Gaeseong to carry on with their family businesses, then established modern companies with capital accrued from the ginseng industry. An analysis of the commercial activities of ginseng merchants in the early 20th century confirmed that these individuals were pioneering entrepreneurs who adopted the ESG management philosophy. In ginseng merchants, one sees a dimension of capitalism with a human face, as with ginseng thatsaves human life.

The aim of this essay is to illustrate Sunjung Manhwa in the 1970s which has been alienated in comics studies. This essay analyses the articles and the serial comics in Schoolgirl, the magazine in the 1970s, and examines the ideal representations of the girls at that time. Sunjung Manhwa is really different between the 1960s and 1970s. It cannot be explained on this gap just by analyzing Sunjung Manhwa in book form alone. Even though the censorship on comics was the element that has hampered the development of comics as a whole, the slumps of Sunjung Manhwa in the 1970s were very excessive compared to other comics genres. This article can gain the answers to the reason of the changes of Sunjung Manhwa by studying the magazines which was the main mass media aimed at girls with Sunjung Manhwa. While the articles in magazines show the editing direction and its characteristics, they reflect the values and ideologies at that time. The same is true for the comics in the magazines. Especially, the comics in the magazines was relatively free from the censorship. This essay examined how the articles and the comics in the girls' magazine in the 1970s represented the images of girls at the time by focusing on feature articles and comics in the magazine, Schoolgirl. This article explored Um, Hee-Ja's Blue Zone and Bang, Young-Jin's Mini March among a full-length serial comics in the magazine, Schoolgirl. Both Blue Zone and Mini March reveal the images of an ideal girl that has been emphasized by the articles in Schoolgirl. Blue Zone draws the appearances of an earnest and obedient daughter, and Mini March represents the figures of a cheerful and bright girl. Through this study, it can be recognized that the magazines in the 1970s highly appraised girls who are obedient to a given society and serve to a harmonious family as ideal ones, and it might be guessed that the ideal images of girls that was characterized ceaselessly by the magazines were the standard of the censorship on comics and its creativity and had also a huge impact on the contents and the expressions of a great deal of works. The 1970s was the times when its importance has been lost in the history of the comics studies by the censorship on the comics and the monopoly of "Hapdong(합동) publisher." The limits of expression in terms of censorship were awfully distinct, so its result was few of good works in quality, and there are still many blanks in the study on 1970s' comics. This study has a meaning which fills up a blank in the comics studies.
