The aim of this study is to analyze the research trend focusing on Yangseng(養生) studies in Korea. Through this study, the researchers attempt to explore the research trends of the Yangseng(養生) in Traditional Korean Medicine. Yangseng(養生) as a key word was searched on representative domestic databases of articles and the researchers and collected the articles of journals published from 1980 to 2012. Finally 350 articles of Yangseng(養生) were selected. After mid-2000s, Yangseng(養生) studies has been increased with the great interest in quality of life. Taoism and Traditional Korean Medicine were closely related with Yangseng(養生). Most of the Yangseng(養生) Studies in Medicine have been carried out by Traditional Korean Medicine and primarily focused in the literature. Yangseng(養生) has been defined as a sort of health-promoting behaviors. Therefore, Yangseng(養生) studies that mainly analyzed the variables associated with health-related quality of life and Yangseng(養生) and the main subjects were elderly and workers in this study. But every measuring instrument except Yangseng(養生) was adapted from western tools. In order to handle the new wave of society and medicine, new health concept and measuring instrument of Traditional Korean Medicine should be developed through Korean unique ideas of Yangseng(養生).

To characterize ecotoxicological responses to a natural estrogen, $17{\beta}$-estradiol, we evaluated the life-history of the parental ($F_0$) and first generation ($F_1$) of the harpacticoid copepod, Tigriopus japonicus sensu lato. We evaluated the survival of nauplii and copepodites, the number of days until the emergence of copepodites and adult males, the sex ratio, brooding success, and the first brooding day of adult females. No significant differences in the survival rate were noted in response to treatments with different concentrations of $17{\beta}$-estradiol. However, $17{\beta}$-estradiol induced developmental delay and skewed the sex ratio toward males. Copepod development was delayed significantly in the 0.1 and $1\;{\mu}g\;l^{-1}$ $17{\beta}$-estradiol treatment groups relative to the control group, with a more pronounced delay in the $F_1$ group. Body length and biomass were significantly smaller in the $17{\beta}$-estradiol treated groups than in the controls. The male emergence of T. japonicus s.l. was very high in the 10 and $30\;{\mu}g\;l^{-1}$ $17{\beta}$-estradiol treatment group. Furthermore, exposure to $17{\beta}$-estradiol resulted in morphological deformities such as shrinking and swelling of the urosome, twisted setae of the caudal rami, setal loss of swimming legs, abnormal segmentation of antennules, and dwarfism.

Place memory is a new way of seeing as a new concept of cultural landscape research. Various research works and discussions have recently spread in landscape studies. In particular, the, which is visible and material, is a medium in which collective memory is embedded in place memory. The purpose of this study is to extract places of memory from the collective memory of residents of Janghang, Korea, and to visualize it through semantic relations. For this purpose, semi-standardized interviews (34 persons) were conducted with residents, and frequency analysis and semantic network analysis were used. As a result, the interviewees recalled only 127 places in Janghang that existed between 1920 and 2010. Locals remember the city based on places of memory. This means that the city could be illustrated according to specific places that are frequently mentioned. For instance, the top 25 places (top 20%) explain 65.6% of all the places in the city, and the top 39 places (top 30.8%) could describe 78.7% of the places. Some places are referred to more frequently when they are in the city's symbolic landscape, and the city's identity is projected on them. Some places were mentioned only infrequently but were nevertheless very important places by which to understand Janghang. These places of memory have not appeared in the documentary records before, which shows the value of the collective memory of the locals and the effectiveness of the interviewing method. In the clustering of the semantic network, six groups of places appeared. The local residents remembered the modern industrial city and recalled it in connection with the sites of daily life. This shows the possibility of looking not only at public memory and famous heritage as a macro history but also at daily life and meaningful places as a micro history about locals. This study has significance as an initial research that identified and visualized places of memory from the perspective of local residents. Such an approach could be useful in the study of everyday life and the conservation of modern heritage.

Objentive : This study was aimed to take a sensus of elementary school children who have atopic dermatitis(AD) especially the residents of Je-Cheon. Methods : We conducted a questionnaire survey of the elementary school children in Je-Cheon who have atopic dermatitis. 86 patients with AD were involved in the survey. The questionnaire was made up of their family history, past history, type of residence, favorite food, kinds of treatment, methods and satisfaction of oriental medicine treatment, use of complementary therapy, and hardship of life on atopic dermatitis, etc. Results : Parents' past history has a effect on children's AD. Especilly mother's has the greatest effect. About past history of patients, allergic rhinitis is most commonly found. Apartment is the most usual form of residence. Patients with AD enjoy meat diet, ice cream. They prefer western medicine treatment to oriental medicine treatment or popular remedy. They usually got oriental medicine treatment at clinic. Herbal remedy is used most frequently. About 77% of children are satisfied with oriental medicine treatment, and about 72% of children use complementary theraphy. Their favorite complementary theraphy is to apply humectant. Because of atopic dermatitis, about 74% of children have difficulty in daily life. And about 10% of children feel mental pressure. Conclusion : We analyzed not only patients' genetic, environmental factors but also use of complementary theraphy, method and satisfaction of oriental medicine treatment, etc. Through the survey, we could understand the actual conditions of elementary school children who have AD in Je-Cheon.

Introduction : Sasang Constitutional Medicine (SCM) is one of the most popular specialty in Korean traditional medicine. After Donguisusebowon (東醫壽世保元), the book initiated SCM at first, there have been several books related with SCM. Through this study on Donguisasangsinpyeon (東醫四象新編), we intend to present clinical application of SCM and the spread of its use. Methods and Discussion : Firstly, we will examine the author's life and philosophy, and consider various editions of Donguisasangsinpyeon. And we will attempt content analysis to the preface, foreword, afterword, and main text. Using these methods, we will show that Donguisasangsinpyeon not only succeed the theory of Donguisusebowon faithfully, but also expand the clinical use of SCM. Conclusions : Donguisasangsinpyeon is the first SCM-based clinical book after Donguisusebowon. And the book can also be valued for its adoption of explanatory diagrams that help people select customized prescriptions conveniently and easily.

We investigated to egg development and early life history of Tribolodon brandtii in the Korean peninsula. The fertilized eggs of the T. brandtii were slightly adhesive and separated with a yellow yolk and no oil globule, and they was an average of $2.4{\pm}0.2mm$ in diameter. The hatching of the embryo took place in about 60 hrs after fertilization under water temperature of $20{\pm}1^{\circ}C$ and the newly hatched larvae were average $6.4{\pm}0.4mm$ in total length. At 10 days after hatching, they were average $11.7{\pm}0.2mm$ in total length and their yolk sac were completely absorbed. At 46 days after hatching, they became to juvenile stage and reached $19.6{\pm}2.7mm$ in total length and all their fin rays were formed. At 125 days after hatching, the juvenile were $54.9{\pm}15.8mm$ in total length and their body shape were similar to the adult fish. At 236 days after hatching, they fish were $54.9{\pm}15.8mm$ in total length and their body color were similar to the adult fish.

In 2013, the epidemics of pine wilt disease caused by the pine wood nematodes (Bursaphelenchus xylophilus) resulted in damages to the forests of black pine (Pinus thunbergii Parl.) trees in Jeju Island, Korea. Among the affected trees, an old black pine tree at Cave Temple on Mt. Sanbangsan was included and died due to the prevalence of pine wilt disease. The tree was on Mt. Sanbangsan, which was designated as a National Scenic Place with the Number 77 and was believed to be more than 400 years old in age. By examining the disc of the tree stem obtained from the height of 2 m, we counted the tree rings from 4 different directions and cross-dated the readings by comparing the records of drought simulated from the BROOK Model. Our analysis indicates that the tree seems to have grown since late 1860s. Contrary to the belief of the general public, we can conclude that the age of the tree was estimated to be at maximum 150 years, which means that it was not the same old tree as was shown in the painting of the Tam-Ra-Sun-Ryeok-Do (an old painting book for the Inspection Tour of Jeju Island) published in 1702. Discussion was extended to the life history of the tree in growth and leaning and the measures to protect the tree species from the damages of the pine wilt disease caused by pine wood nematodes.

Oilseed rape (Brassica napus L.) is an important crop due to its high oil content in the seed. Recently, the demand for the improvement of crop for biodisel energy source is increased as oil prices in the world has increased dramatically. Until now, oilseed rape breeding was carried out by cross-hybridization between different varieties and related germplasms. However, like as many other crops, the application of tissue culture and gene transformation systems has been introduced into oilseed rape breeding program including the development of transgenic canola plants. In this study, we reviewed a history of tissue culture and genetic transformation research in oilseed rape plants and indicated some important aspects for the production of transgenic oilseed rape plants.
