  • This study was performed to present new insights into the distinct aspects of Jehotang. Its history, significance, and effects were examined by evaluating the pertinent literature. In which the idea that Korean foods were original sources of medicine was well expressed. This study was also conducted with the anticipation that it may be useful in developing new foods and beverages based on modern science. References to the Jehotang were found in nine Korean medicine books, seven general books, and in dynastic records such as Bibyeonsa deungnok, Joseonwangjosilrok, Seungjeongwon Ilgi, etc; thus, it was likely a food since the early Korean age. Furthermore, it was discovered that in the Chosun era. Jehotang was not only drunk as a soft drink at the Royal Court in the summer, but was also used as a royal gifts to Cabinet members at the Tano festival on the fifth day of the fifth month of the lunar calendar.

  • Reproductive activity in the economically important insect, Antheraea mylitta is very important because the female reproduces only once in her life time and the aging is very rapid and costly. It is a capital breeder and strictly a monoandrous species. To know how strategically the insect behaves and the male allocates its ejaculate resource more prudently during its successive mating with virgin females to maximize its own fitness and the fitness of the female with whom it mated, both being most important to sericulture industry. So, the present study was undertaken and the results revealed fresh and virgin females always prefer to mate with fresh virgin males (84%) and receives high dose of ejaculates leading to higher hatchability than to virgin males of one day old (13.7%) and one day old males with mating experience (2.3%). The ejaculation size (as referred to eupyrene sperm count in the ejaculation) declined significantly over successive mating (r = -0.9931, P < 0.001), so also the male body weight (r = -0.9560, P < 0.001). The quantity of ejaculate passed to female also dramatically declined during aging (r = -0.9982, P < 0.001). It was found that male weight contribute substantially to the quantum of ejaculate (r = -0.9519, P < 0.001), so also higher fecund females receive relatively more ejaculate than the lower group to reach higher reproductive fitness. The life time fecundity was found to be $334{\pm}31$.

  • The organic contents of reservoir sediment can offer a good indicator to events in history of lake life. Reservoir sediment have many information of the past and future fingerprint about development direction of life cycle in biological animals. So, in this study we made an effort to know the distribution of organic contents in Daecheong reservoir sediment. Items for this investigations are such as follows: Loss on ignition, COD, Organic carbon, TN, TP, heavy metal contents, Loss on ignitions were determined in 6.44~15.91% and COD were determined in 1.606~6.859%, organic carbon in 1,077~3.743%. Contents of TP and TN were in the range of 0.083~0.757%, and 0.645~0.926%, respectively.

  • Objectives: This study proposes a new form of English translation in comparison with that shown in English books related to Sasang Constitutional medicine formulae which have been published up to now. Methods: This study formulated a new form of English translation guidelines by making a comparative analysis of the English translation cases listed in "Korean-English Dictionary of Oriental Medicine", "Longevity and Life Preservation in Eastern Medicine", and "Introduction to Sasang Constitutional Medicine". Results: This study as a common rules suggested that names of preparation form should be placed at the very end of the formula name and the first letters of the major words of the formula name should be capitalized. In addition, for the sake of accuracy in English translation of the formula name, this study divided the formula names into 8 types. The 8 sorts of types include: (a) Materia Medica + Preparation Form, (b) Materia Medica + Indication + Preparation Form, (c) Materia Medica Numbers + Preparation Form, (d) Indication + Preparation Form, (e) Concept + Preparation Form, (f) Concept + Materia Medica + Preparation Form, (g) Concept + Indication + Preparation Form, (h) Etcetera. In these types, medicinal herbs should be written in scientific name, and translation of indication can follow Noun+~ing participle form. In case of the terms having a Korean-medicine-based meaning, this study aimed for source-oriented translation. Conclusions: This study provides a general English translation method and examples of the formula names for Sasang constitutional medicine.

  • Han-ok has a long history and cultural traditions. It has green and healthy and culture but high construction costs, thermal insulation performance of residential and vulnerable to fires and have a weakness for maintenance. However, modernized resident housing, Han-ok is required to improve in terms of environmental aspect due to its weakness for insulating and inconvenience for modem era. Also Han-Ok's building is criticized as a huge dependence on subjective building experiences. This is pointed to be the biggest problem, Han-ok has. Traditionally it does not have a scientific and specific manual for construction. In this research, process simulation was adopted to develop Han-Ok's environmental improvements. In terms of LCC (Life Cycle Cost) aspect, however, Han-Ok's environmental characteristics are examined to suggest an appropriate Han-Ok construction method. Also the result of this research would be utilized to base the information database for efficient constructing and its management in new Han-Ok constructing industry.

  • To research the trends of study about gastrointestinal (GI) disease in Korean medicine, we reviewed and analysed articles published in Korea from 2009 to 2012. From ancient to modern history, traditional plant-based medicines have played an important role in health care, especially GI tract. In spite of the great advances of moderm scientific medicine, traditional medicine is still the primary form of healing methods readily available to the majority of the people in the many countries. In fact many of today's popular drugs have their origins in traditional medicine. Therefore, we suggest that the development and improvement of Korean medicine in GI tract will make good the quality of life in our lifetime.

  • A revised checklist of Korean Trichoptera is provided for the species recorded from the Korean Peninsula, including both North and South Korea. The checklist includes bibliographic research as well as results after reexamination of some specimens. For each species, we provide the taxonomic literature that examined Korean Trichoptera materials or mentioned significant taxonomic treatments regarding to Korean species. We also provide the records of unnamed species based on larval identification for further study. Based on taxonomic considerations, 20 species among the previously known nominal species in Korea are deleted or synonymized, and three species omitted from the previous lists, Hydropsyche athene Malicky and Chantaramongkol, 2000, H. simulata Mosely, 1942 and Helicopsyche coreana Mey, 1991 are newly added to the checklist. Hydropsyche formosana Ulmer, 1911 is recorded from the Korean Peninsula for the first time by the identification of Hydropsyche KD. In addition, we recognized 14 species of larvae separated with only tentative alphabetic designations. As a result, this new Korean Trichoptera checklist includes 218 currently recognized species in 66 genera and 25 families from the Korean Peninsula.

  • Using a life course framework, we compare and contrast the processes of acculturation for first- and second-generation Korean immigrant fathers in the United States. In-depth life history interviews were conducted with 20 first-generation and 15 second-generation fathers in the Midwest. With a modified grounded theory approach of constant comparison, we first explored how these fathers developed their identities in the midst of cultural and social transitions. These men's identity construction was shaped by socio-economic statuses and accessibility to cultural resources, with a marked shift over time toward integration of Korean and American identities. We then examined how these identities informed the men's socialization of their children, and the children's socialization of their parents.

  • By taking a bottom-up "library in the life of the user" perspective rather than a top-down "user in the life of the library" perspective, this paper uses anecdotal evidence from the past and near present to examine the multiple roles the U.S. public library plays and has played as public space in the everyday lives of its patrons. By harnessing "public sphere" theory discussed in Jurgen Habermas's THE STRUCTURAL TRANSFORMATION OF THE PUBLIC SPHERE (1989) and by the examining the rich literatures on civic life and institutions that have evolved from it, the author argues that Library and Information Studies discourse has to expand its scope to include research and analysis of "library as place" from a user's perspective if it hopes to develop a deeper understanding of what the public library does for means to members of the communities in which they reside.
