In the late Joseon Dynasty, patriarchal ideology became central to the family and the clan, and once again became acutely felt with "the familism of clan rules that centered around a legitimate and eldest son." The establishment of the family-clan system, though somewhat complex, was largely aimed at the family line of "a paternalist-a legitimate and eldest son." The trend was not limited to a particular family, but rather, was a historical and social trend. Changseonggameirok showed how to solve the family crisis by setting up a problem for the next generation's patriarch. This paper tries to explain the issue of Hwachun's complex as the legitimate and eldest son complex. First, it suggests that Hwachun's complex is as universal as the Cain complex, also known as the eldest son complex, and that Hwachun's complex is a special instance of the legitimate and eldest son complex in Changseonggameirok. Next this paper studies the aspects of Hwachun's legitimate and eldest son complex combined with Mrs. Sim's complex, as well as her daughter-in-law's complex, and eventually tracks the development of the family-clan complex. As a result, we've come to a new conclusion that the legitimate and eldest son complex was found in Changseonggameirok for the first time in Korean literary history. This paper also examines the fact that when the legitimate and eldest son complex was transferred to Hwajin, it became a family complex that Hwajin had to contend with; this paper tracks the process wherein Hwajin's filial piety solved the legitimate and eldest son complex. As a result, we realized that Hwajin's filial duty and brotherly love went beyond his feelings for Mrs. Sim and Hwachun, and supported the substantiation for "the familism of a clan that is based on rules of the legitimate and eldest son" in the course of public opinion. However the familism of these rules was not embodied in the absolute; in the royal family, for example, it was rather flexibly implemented when the characters admitted to breaking the law. In addition, this paper provides the room for a critical reading of Changseonggameirok, reflecting back on the underlying guilt and psychological pain of the characters who are affected by the particular rules, and concluding that guilt and suffering are fundamentally insoluble. This is because the two ideas, "the legitimate and eldest son complex" and "the familism of a clan rules centered on a legitimate and eldest son" are two sides of the same coin.

Nowadays there are many sun protection cosmetics including organic or inorganic UV filter as an active ingredient. Chemically stable inorganic sunsEreen agents, usually metal oxides, we widely employed in high SPF products. Titanium dioxide is one of the most frequently used inorganic UV filters. It has been used as pigments for a long period of cosmetic history. With the development of micronization techniques, it becomes possible to incorporate titanium dioxide in sunscreen formulations without whitening effect and it becomes an important research topic. However, there are very few works related to quantitations of titanium dioxide in sunscreen products. In this research, we analyzed amounts of titanium dioxide in sunscreen cosmetics by adapting redof titration, reduction of Ti(IV) to Ti(III) and reoxidation to Ti(IV). After calcification of other organic ingredients of cosmetics, titanium dioxide is dissolved by hot sulfuric acid. The dissolved Ti(IV) is reduced to the Ti(III) by adding aluminum metals. The reduced Ti(III) is titrated against a standard oxidizing agent, Fe(III) (ammonium iron(III) sulfate), with potassium thiocyanate as an indicator In order to test accuracy and applicability of the proposed method, we analyzed the amounts of titanium dioxide in four types of sunscreen cosmetics, such as cream, make-up base, foundation and powder, after adding known amounts of titanium dioxide $(1{\sim}25w/w%)$. The percent recoveries of the titanium dioxide in four types of formulations were in the range between 96 and 105%. We also analyzed 7 commercial cosmetic products labeled titanium dioxide as an ingredient and compared the results with those of obtained from ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry), one of the most powerful atomic analysis techniques. The results showed that the titrated amounts were well coincided with the analyzed amounts of titanium dioxide by ICP-AES. Although instrumental analytical methods, ICP-MS (Inductively Coupled Plasma-Mass Spectrometry) and ICP-AES, are the best for the analysis of titanium, it is hard to adopt because of their high prices for small cosmetic companies. It was found that the volumetric method presented here gat e quantitative and reliable results with routine lab-wares and chemicals.

This study was conducted to identify students' meaningful scientific experiences and to ascertain the path through which the experience led to learning. The subjects of 'Understanding of the History of Science' were asked to write an essay on the subject of 'Effects of science on my life' to 81 students in the department of literature and 125 students in the science department. After that Classification criteria were established through scientific experts' seminars, and the scientific experiences that affected students and their effects were examined. The results from analyses were summarized as follows: First, As a result of study about Science Education experience that has impacted students' lives, the students were influenced by images, most of which were influenced by scientific videos. They were also influenced by science classes and science books. As a result of classifying science experience, most of the experience is composed of Informal Science Learning. Second, as a result of examining how students were influenced by their scientific experience, they found that they were affected by their daily life or influenced by science. As a result of the research, it can be confirmed that Informal Science Learning experience is an important learning form that has a great influence on students. Therefore, appropriate Informal Science Learning experience should be introduced into the class, and research and development on the Informal Science Learning experience preferred by the students should be done.

This article examined that the historical changes and current significance of the Jaedam(재담) and the Xiangsheng(相聲), one of the traditional Korean and Chinese language games. Both Korean Jaedam and Chinese Xiangsheng are representative language games and traditional performing arts for laughing. The origin of the Jaedam can be traced back to Uheui(우희). Uheui has been called Changyouxi in China, Bae Woo-hee, and Jo Hee in Korea. Uheui is the most traditional language game and a variety of performances were derived from its spreading and inheriting process. Among them, Korean Jaedam and Chinese Xiangsheng can be said to be a piece of art that has successfully inherited Uheui tradition. From the late 18th century, Korean Jaedam were established as independent performance arts, and became highly active in many performance by professional joker Park Chun-jae and other performers. With the development of gramophone record in the early 20th century, the Jaedam was mainly made on the theater stage and radio. At this time, the new performance art of 'Mandam(만담)' was derived from the Jaedam, which focused more on satire current events and criticizing the social situation. Mandam has been popular for a long time and then extinct in the 21st century. The jaedam have been handed down only in the Korean traditional performance so far. Meanwhile, Chinese Xiangsheng, which was built in the mid-19th century, a bit later than Korean Jaedam, was initially considered to be a vulgar art of the lower class, but finally became popular in the early 20th century. In the mid-20th century, Xiangsheng was transformed into a new character, which mainly deals with social praise and edification of the masses. But since 'New Xiangsheng' does not focous on a satire on social conditions, the humor has been reduced. In the early 21st century, Xiangsheng was on the verge of extinction just like Mandam, but through the efforts of young actors to revive tradition, another reformation of this art was made to return to tradition and small theater. Currently, the 'traditional Xiangsheng', which has returned to tradition, is once again receiving the love and support of the Chinese audience. Korean Jaedam and Chinese Xiangsheng have many similarities in terms of history and recruitment, but they are now in different fates. There is also a great deal in common ground in terms of the content and form of the two arts. In the case of Xiangsheng, it is one of the traditional folk art forms which is still loved by the Chinese people and has become one of the most important traditional performances. On the other hand, in Korea, Jaedam as independent performance arts has disappeared and now only can be seen in traditional performances such as 'Korean mask theater'. The fact that Korean Jaedam and Chinese Xiangsheng have undergone similar changes in their spreading and inheriting process, while Korean Jaedam have disappeared and Chinese Xiangsheng is well preserved. The reason can be confirmed through the main idea of this article.

The Musical Theatre was a popular art genre that originated from the western musical tradition represented by the European opera. In the twentieth century, it bloomed around Broadway in the United States. It is also one of the commercial arts which is popularly loved by the public in the field of performing arts all over the world at present. Due to the nature of this genre, the development of dramas and the expression of characters use music, not words or gestures, as the main medium. And the style of music reacts sensitively to the taste of the public, not to a particular class. When Japan colonized Korea, the empire strongly believed modernization equaled westernization and Japan was the one who could awaken Korean. The Japanese colonial music education was intended to bring cooperation and obedience to Japan by forcibly injecting Japanese ideology and culture into Joseon people. The music education of colonialism with the textbook of the "Songs for public education(보통교육 창가집)" compiled by the Japanese government was a sparkstone for the conversion of the Korean musical identity to Japanese and Western music. In addition to the capitalistic economical mechanism for establishing a South Korean government friendly with the United States during the Cold War after liberation, and the rush of American Pop culture represented by 'the show stage in 8th US Arm' and 'movies' which are to be the influence of invisible 'new cultural imperialism', our traditional music was confined to the meaning of 'Korean music', meaning 'past music'. In Korea, after the liberation, the musical was introduced by the influx of American popular culture. In accordance with the cultural policy of Park Jeong-hee regime, which aimed to spread the 'healthy culture' through the modernization of traditional arts, 'The Yegreen(예그린악단)' was founded. However, the plan to create a contemporary performing art based on Korean national arts showed the possibility of success in 1966 with the success of , but soon after, they have been destined to fall into an institution that has lost their ability to operate on their own due to the suspension of the sponsorship of the regime. Due to the cultural imperialist strategy of the influence of Japanese imperialism's colonial music education and influx of American popular culture after liberation, in the early days of Korean musicals, our traditional aesthetic style brought about the situation of the 1960 's, which did not become an independent ethnic art through the exchange and expansion with Western music. This is the background of the western licensed musicals led by the Korean musical market in the 21st century as well as the main cause of musical creation based on western music.

Nowadays Korean main archives and manuscript repositories are planning to develop archival information service for students and teachers in their web sites. This study is aimed at discovering main issues of developing archival information service for students and teachers and finding a solution. The goal of archival information service for students and teachers is the promotion of use through launching service and the gradual growth of archival management program. The customer group is segmented into the students and teachers who are learning and teaching Korean history in classroom. As a result of analyzing curriculum and educational environment, the archival information must be developed into teaching-learning materials. And the processing archival information into archival content is needed. Consequently the character of archival information service for students and teachers is conceptualized as archival content service for teaching-learning materials. At every step of developing archival content service for teaching-learning materials, the next main points are considered and achieved. First, the strategy of customer-focused service must be the same from beginning to end. Second, the growth of traditional archival management(e.g. classification, description and finding aids) must be contributed. Third, the collaboration system leading by professional education staff must be organized. Fourth, the archival information must be related with teaching-learning activities. Fifth, the quality of content is more important than the quantity of it. Sixth, the networking with another agencies for cooperation must be considered.

Koguryo's tomb mural paintings in North Korea are our precious cultural heritage which have been designated as UNESCO World Heritage property receiving high praise in the following criterion, i) exceptional creativeness of human being, ii) representative value showing the stage of development in construction history of East-Asia, iii) aesthetic superiority iv) uniqueness of building construction including tombs' ceiling. Mural paintings have been found from almost 100 tombs of the Koguryo dynasty out of 130 which are scattered across Huanren County, Lianoning Province, Ji'an, Jilin Province in China and Pyongyang in North Korea. Especially, most of them are gathered in Pyongyang from 4th and 5th century. Peculiarly, some of them have been constructed before King Jangsu's transfer of the capital to Pyongyang(AD 427). It can be regarded that Pyongyang territory had been under control of Koguryo and to become a new capital in the near future. And dense emergence of such tombs since the capital transfer from Gungnae City to Pyongyang during the reign of Jangsu is linked closely to the construction of tombs for rulers under strengthen royal authority of Jangsu and centralized system of authoritarian rule. Tomb mural paintings describe the owner's figure pictorially based on the truth just as in his living years. General lifestyles of ruling powers and sovereigns can be seen from the wall paintings portraying several buildings with various styles, figures, manners of living, which are considered that the tomb owner had led politically and sociologically in his life. In spite of not enough proofs to approve figure of architectures or "Gong-Po" in wall paintings on the tombs as those of Koguryo, it is persuasive with consideration for painting and decoration inside the tomb like wooden building in real life for the purpose of reenacting and continuing the tomb owner's luxurious life after death. "Du-Gong-Po-Zak" had appeared in company with Koguryo tomb murals and it can be found in most of the murals. And the emergence of substantial "Gong-Po-Do" can be counted more than a century ahead of the figure in murals. It could be a reasonable assumption as regards Koguryo tomb murals time of appearance match up with production period of Gahyungmyunggi(家形明器) and Hwasangseok(畵像石) Hwasangjeon(畵像塼) Design in the Mural Painting of the East-Han(東漢) Ancient Tombs in China. On this study, architectural "Gong-Po"s described in Koguryo tomb murals are categorized largely in "Bi(non)-Po-Zak-kye", "Jun(semi)-Po-Zak-kye", and "Po-Zak-kye" based on presence of "Ju-Du", "Cheom-Cha", and "Cheom-Cha-Sal-Mi" with developmental aspect, and, "Po-zak" is subdivided as "Bi(non)-Cheul-Mok" and "Cheul-Mok" types.

This study examined the background of Gyeongju Seochulji Pond (world heritage, historic site No. 138), a historic pond in Sam-guk-yu-sa (三國遺事), and its landscaping period when it served as the garden of the Pungcheon Lim clan (豊川 任氏) in the middle of the Joseon dynasty. For this study, a literature review of poetry, prose, and a personal anthology, and a field survey were conducted. Changes in the landscape were analyzed by comparing the landscape appearing in the literature of the Joseon period with past photographs. The results were as follows: First, even though the function and landscape at that time cannot be guessed as the objective ground from Silla to the early part of the Joseon dynasty is insufficient, it has been managed as a Byeolseo (別墅) garden as Pungcheon Lim's family resided in the area of Eastern-Namsan Mountain during the Joseon dynasty. At that time, Seochulji Pond was recognized as a historic place. It functioned as the garden of Pungcheon Lim's family as Lim Jeok (任勣, 1612~1672) built the Yiyodang pavilion (二樂堂). Second, in the literature, the Yiyodang pavilion has been called Gaekdang (客堂), Jeongsa (精舍), Byeolgak (別閣) and Byeolseo, etc. It can be seen as Nu and Jeong (樓亭), utilized for various uses. Because of this, the name Bingheoru Pavilion (憑虛樓) has mostly been in common use. Third, Seochulji Pond was positioned where the scenery is beautiful, with Gyeongju Mt. Namsan (Mt. Geumo) in the background and with a wide field and the Namcheon River flowing in the front. This was typical of Byeolseo gardens of the Joseon dynasty, combining human environments with natural environments. Fourth, the relationship with the Byeolseo garden disappeared as the head of Pungcheon Lim's family added a temple, lotus flowers, pine trees, and a bamboo forest as described in the old poetry and prose. Currently, the landscape does not appear to be significantly different from that as development has not occurred in the area of Seochulji Pond. Also, crape myrtle (Lagerstroemia indica), which now symbolizes the Seochulji Pond, was not identified in the old poetry or past photographs and is not old enough to confirm whether it was prominent at the time. Through this study, it is necessary to reconsider the spatial meanings of the gardens of the Joseon dynasty period and not to highlight the area of Seochulji Pond as a place in the legend. This is a cultural asset in the area of Eastern-Namsan Mountain and has an important meaning in terms of garden history.

There are 35 cultural properties of fourteen kinds in the Demilitarized Zone known so far, but this number is expected to increase in the future. Among them, Cheolwon-Doseong and Jeongol-Chong of Gimhwa should be the first step toward conservation efforts by conducting a joint investigation through the collaboration of North and South Korea. In particular, the joint investigation of Cheolwon-Doseong will not only remind the North and South that they are the same people who have had common history and cultural traditions for a long time, but will also give symbolic meaning to convert the demilitarized zone into a stage for peace. Since Jeongol-Chong is a mass grave of the fallen soldiers of Pyeongan Province who fought against the invasion of the Qing of China, it should be managed as a national designated cultural asset through joint investigation. In addition, the Demilitarized Zone should become a World Heritage Site because of its importance to the legacy of the Korean War, an international war caused by an ideological confrontation. Furthermore, it has more than 6,000 kinds of temperate forests in addition to 100 species of endangered species and natural monuments. The DMZ is very qualified to be a World Natural Heritage Site, and should be included as a World Complex Cultural Heritage Site that qualifies as a World Heritage and World Natural Heritage Site. In the Demilitarized Zone, we can also find numerous highlands, tunnels and posts used during the Korean War, as well as surveillance posts, a military demarcation line, barbed wire fences, and Panmunjom, which were created by the armistice agreement. it would be desirable to select some of its sections and war facilities and to register them as modern cultural heritage assets. Finally, it is necessary to reconstruct the Dorasan Signal Fire Site, which was the communication facility of a traditional era which connected the South (Dorasan) and North (Gaesong). This would symbolize smooth communication between the two Koreas. In order to prepare for the reckless development of the Demilitarized Zone due to the upcoming cease-fire, the government and cultural asset experts will have to work hard to identify and preserve the cultural properties of the Demilitarized Zone, and they will also have to maintain consistent control over matters such as indiscriminate investigation and mine clearance.
