The purpose of this study is to present a concrete image of the ideal beauty as shown in era preceding 1945 that effects the shaping of our aesthetic values; by analyzing its characteristics through the covers of women's magazines of that period, this research aims to promote the understanding of beauty of the human body. The scope of my research extends throughout the collection of women's magazines stored in the National Library and the Korea Magazine Information Center. The gathered research materials are: 5 kinds of Shin-Yeo-Sung (신여성), 51 kinds Yeo-Sung(여성) and 30 kinds of Ga-Jung-Ji-Woo(가정지우). The result of the research could be summarized as the followings. Before the 1920's in response to the violent opening, there was a trend of sticking to the traditional standard. In the 1920's, the prevalent images of women were meek and fragile. Japanese standard of beauty was explicitly indicated. In the 1930s, as Western movies started to be shown to the general public, western features were idealized and furthermore intelligence was required as a further condition. In the 1940s, preparation of the war led to encouragement of images of motherhood and natural beauty, and resistant to this trend led to pseudoclassicism.

This study compared the meaning of words in the play songs of the Democratic Peoples Republic of Korea(DPRK). Sixteen children who had escaped from North Korea participated in this survey in Seoul by responding to a questionnaire. In the DPRK, children sing formal songs, used as instruments of ideological socialization. Among the songs were 4 composed prior to the creation of the DPRK in 1945. The other songs were composed after 1945 and exhibited ideological characteristics. Despite differences in sources, themes, and ideologies of play songs, some of them contained common themes, materials, rhythms, and typical Korean emotional structure. Considering the power of play songs in spreading cultural influence, they might be the key to resolving psychological conflicts of both Koreas after unification.

Chilli reservoir is agricultural purpose reservoir made in 1945. But its bottom is covered with thick accumulated sewage layer, so its original function has failed. This study conducted cadastral state surveying to survey the state of this area prior to dredging the accumulated bottom sewage layer of Chill reservoir. Prior to cadastral state surveying we analyzed the digital map and aerial photographs of study area. In cadastral state surveying, traversed network was constructed on the road and banks near the reservoir, a surveyed map was made by surveying with Auto-reduction EDM Alidade. From the comparison results of the cadastral map and digital map, we found small chilli reservoir is expressed as rice field on the digital map, and it should be corrected. And when we make digital map and topographic map, the errors will be diminished if we use the cadastral map at the same time.

The purpose of this study was to compare the kinds of plays and the meanings of words in play songs among children of Han heritage. A total of three data sets were used. Data for two of the data sets were obtained from only South Korean children in 1990 and 2005, respectively, while the other data set contained responses from South Korean, Chinese Korean, and North Korean children collected in 1999. The three societies of Han heritage differed in the level of economic and industrial development and ideological orientation, and each society tended to socialize and educate their children in different ways. The kind of plays and the lyrics of the play songs were different in each stage by the level of economic and industrial development, and ideological orientation. In each society, a dominant play changed periodically. For instance, physical play decreased while television, video, and internet game plays increased. The increase in internet game play was related to the level of industrial development. Although three groups shared some common play songs prior to 1945, they have developed their own play songs after 1945 according to their respective social ideological characteristics. Notwithstanding these differences in play songs, common themes, materials, rhythms, and the Korean emotionality exist across all groups.

RFID technologies have attracted a lot of attention in recent years because of their cost/time-effectiveness in large-scale logistics, supply chain management (SCM) and other various potential applications. One of the most important issues of the RFID-based systems is how quickly tags can be identified. Tag collision arbitration plays a more critical role in determining the system performance especially for passive tag-based ones where tag collisions are dealt with rather than prevented. We present a novel tag collision arbitration protocol called Optimum Frame-Slotted Aloha (OFSA). The protocol has been designed to achieve time-optimal efficiency in tag identification through an analytic study of tag identification delay and tag number estimation. Results from our analysis and extensive simulations demonstrate that OFSA outperforms other collision arbitration protocols. Also, unlike most prior anti-collision protocols, it does not require any modification to the current standards and architectures facilitating the rollout of RFID systems.

Breast radiologists are increasingly seeing patients with axillary adenopathy related to COVID-19 vaccination. Vaccination can cause levels I-III axillary as well as cervical lymphadenopathy. Appropriate management of vaccine-related adenopathy may vary depending on clinical context. In patients with current or past history of malignancy, vaccine-related adenopathy can be indistinguishable from nodal metastasis. This article presents imaging findings of oncology patients with adenopathy seen in the axilla or neck on cross-sectional imaging (breast MRI, CT, or PET-CT) after COVID-19 vaccination. Management approach and rationale is discussed, along with consideration on strategies to minimize false positives in vaccinated cancer patients. Time interval between vaccination and adenopathy seen on breast MRI, CT, or PET-CT is also reported.

This study looks at the origin of a wild-ginseng, Korean ginseng, and traces the origin of associated wild-ginseng digging customs back to the Annals of the Joseon Dynasty. These historical customs helped Korea gain control over its wild ginseng resources following Japanese colonization acts, Korea's present-day forest laws, and Korean Civil Law. Prior to Japanese colonial rule in Korea (1910-1945), ginseng digging was a common custom, but Imperial Japan distorted Korea's own legal principles of the public rights of wild-ginseng digging during this colonial period. Distorted legal principles concerning digging customs continued after Korea's liberation from Japanese rule and were maintained until the enforcement of the Korean Civil Law in 1960, when legal principles of the right of common were changed to special servitude. The origin of the right of common can be found in the Sichojang of the Joseon Dynasty. The Sichojang, a place where local residents jointly collected firewood and fed livestock, was the minimum right to life and interest at the time. Since the right of common was the right to life, Imperial Japan attempted to abolish it, but it was never successful. In addition, distorted legal principles have been maintained in present-day forestry-related laws and regulations. Over 75 years since the liberation from Japanese rule in 1945, it is imperative to break away from the distorted legal principles and acknowledge that digging custom rights have changed from common customs to a special servitude under Korean Civil Law. Hence, an organization of wild-ginseng diggers is an unincorporated association, and their wild-ginseng digging customs can be constituted as a special servitude. Hence, their practices should be considered valid under customary law. Through this, it will be possible to clarify the legal nature and grounds for ginseng-related wild-ginseng digging activities, as well as the civil responsibility for the activities of wild-ginseng diggers.

Advanced geological surveys and exploration activities were first carried out in Korea in 1884 in accordance with a treaty of friendship and commerce between Great Britain and Korea and a treaty of friendship and commerce between Germany and Korea. The first paper by Gottsche, C. was also published in a German Journal in 1886. Efforts toward independent acquisition of Western geological survey and exploration technology were actively promoted by the Korean Empire in the early 1900s, but were frustrated by the Japanese Empire. Systematic geological surveys and exploration were conducted in Korea by Japanese geologists during the Japanese occupation. A basic geological maps(61sheets), a bulletin on the geological survey of Korea, a bulletin and technical report on deposits in Korea, and a coalfield geological survey report were published during this period. Overall, the intentions under lying the geological surveys and exploration activities by foreigners in Korea prior to the Japanese occupation were questionable. However, the results of these surveys and explorations themselves can be evaluated as positive in terms of academic performance.

Moniligastrids are an important yet often ignored earthworm group commonly found in cultivated soils, especially paddy, in the tropical East. Seven new taxa are: Drawida koreana austri, D. koreana nanjiro, D. koreana shindo, D. odaesan, D. jeombongsan, D. companio and D. csuzdii Blakemore spp. or sub-spp. nov. from Korea. Drawida csuzdii is the first new species from North Korea since Lumbricidae Eisenia koreana (Zicsi, 1972). Historical East Asian moniligastrids are reviewed chronologically and Drawida barwelli (Beddard, 1886), D. japonica (Michaelsen, 1892) and D. siemsseni Michaelsen, 1910 are compared on their museum types. These three taxa were thought similar and related to D. nepalensis Michaelsen, 1907 and its possible synonym D. burchardi Michaelsen, 1903 (priority!) and both of these to prior D. uniqua (Bourne, 1887). Indian Drawida calebi Gates, 1945 is compared to new material of D. japonica from Japan, and D. willsi Michaelsen, 1907 to the new sub-species of D. koreana Kobayashi, 1938 from Korea. Where available, mtDNA COI gene barcodes are provided to help objective determinations and a phylogram is provided with outgroup Ocnerodrilidae Eukerria saltensis (Beddard, 1895) itself found in rice paddy/irrigation. The challenge now is comparison of all early taxa in their various homelands in order to assess the genetic variability and taxonomic boundaries acceptable, especially for unpigmented D. barwelli and also for pink/grey D. japonica and blue/grey D. koreana. A checklist of moniligastrids is appended showing 22 species from China (including Hainan and Taiwan), 21 from Korea, nine from Japan and the Drawida ghilarovi Gates, 1969 species-complex from far eastern Russian (Siberia). Recent Drawida dandongensis Zhang & Sun, 2014 from Sino-Korean border is misdescribed and cannot be meaningfully compared to any other Drawidas.

From the cosmopolitan superiority of the as the first world map completed in 1402 with surprisingly detailed images and contents on the Africa Continent it is reasonable to think that the Koreans in early fifteen century were already with highly up-to-date perspectives on the universe and world history and cultures. However, some 490 year later the first phytohydrographic plankton investigation in the neritic seas of Korea was performed by a Japanese company with sampling points covering from Tokyo Bay through Jeju neritic waters to Shanghai estuary, which was in turn preceded by the first oceanographic investigation other than the simple mapping Koreans seas by using two French sailboats. The first phytohydrographic plankton investigation in Korean seas were behind the world first oceanic plankton exploration, the German Plankton Expedition, by 25 years. Starting from the oceanographic investigation including phytohydrographic samplings in the whole Yellow Sea in 1915 the full-scale phytohydrographic plankton studies were tried in Korean seas which is well represented by the 1921 oceanographic investigation on the whole East Sea with 80 sampling stations. In 1932 two separate oceanographic investigations followed, one in the East Sea where 78 stations from Busan to southern Sakhalin Island were simultaneously visited by 50 research vessels for the physical, chemical, and biological oceanographic studies, and the other one in southern coast and western East Sea of Korea where ocean current observation as well as plankton sampling were made in 120 stations to understand the relationship between the ocean current and plankton distribution in the region. In 1933-1934 more intensified investigations on phytohydrography were carried out particularly in the East Sea as an integral part of the basic marine ecosystem studies for the Myeong-Tae (Alaska Pollock) resources estimation. Scientists' attitude for the marine investigation and research activities seemed to be almost unchanging even to the year 1943, which could be reflected by the fact that publication of the results from the investigations performed in 1945 were finally done in 1967 at Tokyo. Some 70 years later from the mid-twenty century we might be standing on the turning-point of "need to be prepared" for the new era of changing paradigm by reviewing, archiving, and analyzing the prior information big data from the previous ocean observation and biohydrographic investigations. At the same time each professional societies for the above mentioned sciences might trigger a continuous project to reorganize and update the records on related bibliography and its history every 30 years.
