To investigate the environmental adaptation and ecophysiological characteristics of Suaeda maritima and S. asparagoides under saline conditions, plant growth and density were analyzed according to environmental changes of habitats. The total ion content of soil decreased with time, which was caused by the predominance of exchangeable $Na^+$ and $Cl^-$ in the upper layers. The population of S. maritima was more densely distributed in the region with higher ion contents of $Cl^-$, $Mg^{2+}$, $K^+$ and $Na^+$ than the population of S. asparagoides. Both species were showed a decreased population density according to increases in plant growth. Under the conditions of a salt field, S. maritima and S. asparagoides contained high inorganic ions to maintain low water potential, but low water soluble carbohydrate contents. In the case of free amino acid, S. maritima showed an especially high proline content, and contained rather large amounts of free amino acids, whereas S. asparagoides did not. Both species showed high inorganic ion contents in the leaves, which might be a mechanism of avoiding the ionic toxicity by diluting the accumulated ionic concentration with a high ratio of water content to dry weight. This result suggests that S. maritima seems to adapt to saline conditions by accumulating proline in addition to inorganic ions. S. asparagoides seems to adapt by osmoregulation processes, using inorganic ions rather than free amino acids.

Objectives : We applied the term weighting method used in the field of data search to quantify relevancy between symptoms and medicinal herbs, and, based on this, we aim to introduce a method of visualizing the characteristics of medicinal herbs. Methods ： We proposed HF-IFF, an adaptation of TF-IDF, which is a term weighting measurement method adapted in the field of data search. Using this method, we deduced relevancy between symptoms and medicinal herbs In Cheongkangeuigam that was published in 1984 by organizing the medical theory of Cheongkang, Kim Younghoon, and visualized this as a graph in order to compare the characteristics of medicinal herbs used for different symptoms. Results ： HF-IFF is the product of HF and IFF, where HF is the frequency of the relevant medicinal herb for a set of symptoms, and IFF is the inverse of the number of formulations (FF) containing that herb. A total of 251 types of medicinal herb are used in Cheongkangeuigam, and 1538 formulations are classified according to 67 types of symptom. The overall mean for HF-IFF was 0.491, with a maximum of 4.566 and a minimum of 0.013. Conclusions ： In spite of several limitations, we were able to use HF-IFF to measure relevancy between symptoms and medicinal herbs, with formulations as an intermediate. We were able to use the quantified results to visually express the characteristics of the herbs used for symptoms by bubble chart and word-cloud from HF-IFF.

The purpose of the study was to investigate the influence of college life adjustment on emotional intelligence in dental hygiene students. Methods: A self-reported questionnaire was completed by 550 dental hygiene students in Daegu from May to June, 2016. The questionnaire consisted of general characteristics of the subjects, emotional intelligence scale, and student adaptation to college questionnaire using Likert 5 point scale. Data were analyzed by t-test, one way ANOVA, post hoc $Scheff{\acute{e}}$ test, Pearson's correlation test, and multiple regression test. Results: The mean scores of emotional intelligence 3.40 points and college life adjustment 3.14 points were above average. Every sub-field of emotional intelligence had static correlation, and there was a close correlation between college life adjustment and every specific field. The academic adjustment (r=0.515) and institutional adjustment (r=0.458) showed strong correlation with the emotional intelligence. The higher the emotional intelligence score was, the higher the college life adjustment was. Variables having statistically significant influence on college life adjustment included economic status, major satisfaction, self-emotional, use of emotional and emotional control (37.7%, p<0.001). Conclusions: Emotional intelligence played a significant role in dental hygiene students to adapt well with the demands of college life. The college should provide the efficient programs in the curriculum that helps enhance emotional intelligence of the students.

Starting with a Korean soap opera in the year 1993, entertainment industry of South Korea such as K-pop, soap operas, Korean celebrities has been introduced and spread throughout China. The new word 'Korean wave' was coined by fans of Korean entertainment culture at this time, and passion on the subject gradually expanded from soap operas to entertainment programs in the market of China. It is necessary to analyze the current situation that Korean entertainment programs gaining tremendous popularity on the entertainment field in China and research on ways to cope with the fierce competition and to change to survive from it. Nowadays Korea has its own unique attribute with its national traits after years of mere imitative adaptation from broadcast program of Japan and that of America since 1980's. Regarding the process, similar situation is ongoing on the entertainment field in China. This paper intends to study potential of Chinese entertainment industry compared to the differences on programs between Korea and China by scoping out success of Korean entertainment program in China and the impact on Chinese entertainment market.

Objectives: In a number of simulated night shift studies, timed exposure to bright light improves sleep quality and work performance. We evaluated the effect of bright light on adaptation to night shift work with a field study. Methods: Five female nurses working shifts at Korea University Hospital were recruited for participation in this study. We investigated two series of six consecutive shift rotations comprising three day and three night shifts, using wrist Actigraphy, the Stanford Sleepiness Scale, Visual-analogue scales, STIM and tympanic membrane temperature for daytime sleep quality, alertness, subjective feeling, attention performance, and temperature rhythm. The subjects were exposed to bright light (2,500 lux) from 24:00 to 04:00 a.m. on three consecutive night shifts during the second series, whereas they worked under normal lightening (650 lux) conditions during the first series. Results: Actigraphic assessment of daytime sleep showed no significant difference between the first and third night shift in both baseline and light exposure phase. The mean lowest temperature shifted earlier during baseline phase but not during the light exposure phase. Also, the score for subjective feelings of depression, anxiety, physical discomfort and sleepiness was significantly higher in the third night shift than the first during baseline phase but not during the light exposure phase. Attention and attention switching ability was significantly improved in the third night shift compared to the first night during the light exposure phase but there were no significant changes during the baseline phase. Conclusion: This result suggests that there were no significant differences between the two phases in measures of quality of daytime sleep, but subjective feelings, attention and alertness were enhanced during light exposure. Although some placebo effects and learning effects might influence this result, bright light exposure between midnight and 4:00 a.m. may improve adaptation to night shift. In future, further controlled studies with a larger sample size, including melatonin measurement, are needed for real shift workers.

The Organic agricultural techinques were investigated through the observations made for 3 years of the actual conditions of a farmer who has been practicing organic agriculture over 21 years. The farmer was a member of the Ichijima-cho Organic Agriculture Association. The Farmer had not performed much of the organic agricultural techinques at the beginning of his farming history. However, he has gradually developed techniques upon the experiences with trial and error. The notable characteristic of his basic organic agriculture was the utilization of a suitable organic fertilizer to make the soil fertile. Crop damages by diseases and insect pests were prevented through a fertile soil, raising of good seedlings, adoption of tolerant varieties and planting at a wide spacing and consequently considering not to use chemical pesticides. Introduction of power weeder for weed control and paddy-upland crop rotation reduced the cost of production for farming. The crop pattern and method of land us such as mix cropping, crop rotation and conversion of paddy field-upland fieldd were appeared to be very important in organic agriculture. The organic agricultural techniques get systematized upon the adaptation the regional ecology and the development of skills of the farmer. The most important point to achieve the success in organic agriculture system is not only by the development of the technical matters but also by the building of healthy relation and understandings between producers and consumers.

Purpose: The purpose of this study was to identify the specific types and characteristics of gender role identity in view of male nursing students. Method: Q-methodology, a technique for extracting subjective opinions, was used. Forty participants completed the Q-sort activity, rating each statement relative to the others. The Q sample has two categories, representing masculinity and femininity, and each category has 20 statements, resulting in 40 adjectives. The collected data were analyzed by QUANL PC program. Results: Three types of gender role identity of male nursing students were identified: 'Taciturn warmth type', 'assertive power type', 'empathic warmth type'. Despite the differences among the types in this research, male nursing students are likely to have the understanding and keep faith. Conclusion: Male nursing students were exposed to many problems because of the gendered culture of nursing education. To understand the male nursing students' gender role identity will help to promote adaptation in nursing field.
