  • Background: Phenological studies are a prerequisite for accomplishing higher productivity and better crop quality in cultivated plants. However, there are no phenological studies on Panax ginseng that improve its production yield. This study aims to redefine the phenological growth stages of P. ginseng based on the existing Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale and proposes a disease control reference. Methods: This study was conducted at the Korea Ginseng Corporation Experiment Station in Gyeonggi province, South Korea. Phenological observations were performed once weekly or twice monthly, based on the developmental stages. The existing BBCH scale with a three-digit code was used to redefine and update P. ginseng's phenological growth codes. Results: The phenological description is divided into eight principal growth stages: three for vegetative growth (perennating bud, aerial shoot, and root development), four for reproductive growth (reproductive organ development, flowering, fruit development, and fruit maturation), and one for senescence according to the extended BBCH scale. A total of 58 secondary growth stages were described within the eight principal growth stages. Under each secondary growth stage, four mesostages are also taken into account, which contains the distinct patterns of the phenological characteristics in ginseng varieties and the process of transplanting seedlings. A practical management program for disease control was also proposed by using the BBCH code and the phenological data proposed in this work. Conclusion: The study introduces an extended BBCH scale for the phenological research of P. ginseng.

  • Stomach cancer shows the highest incidence among cancer patients in Korea and it deteriorates the patients' health-related quality of life considerably. This study measured utility weights of severe stomach cancer symptoms using VAS (Visual Analogue Scale), TTO (Time-trade Off) and EQ-5D (EuroQol-5 Dimension) methods. A survey questionnaire was developed to describe the symptoms of severe stomach cancer comprehensively and concisely using VAS, TTO and EQ-5D. A face-to-face interview was conducted for 21 cancer inpatients in a hospital and 25 non-patients. The mean utility weight is 0.498 for VAS, 0.375 for EQ-5D and 0.300 for TTO. Using VAS or TTO methods, there were no statistically significant differences between patients and non-patients while there was significant difference in EQ-5D. The utility weight with VAS and EQ-5D has shown similar trend - higher score in patient group, male and aged while it has opposite trend with TTO.

  • Recent Construction and Transportation R&D projects are larger in size, investment scale has been increasing rapidly. However, the results of Construction and Transportation in R & D are papers, patents and other results. So, the application record of R&D in the construction field is very lacking. In particular, Construction New Technology's ratio in the midst of R&D's results are about 2.29%. Therefore, this study suggested program that R&D's results has been connected Construction New Technology. The introduction of the new system has greatly increased Construction New Technology and the results of excellent &D will be applied in construction field. So, Cost-reduction and technology's improvement are expected.

  • This study aimed to verify the mediating effect of locus of control on the relationship between materialism and well-being of middle-aged woman. For the study, the survey of 239 middle-aged women in B, C, D city was used. As a scale, a Richins & Dawson(1992)'s widely-used materialism scale, the Levenson(1981)'s locus of scale, Watson, Clark & Tellegen(1988)'s positive and negative affect scale (PANAS) and Ryff(1989)'s psychological well-being scale(PWBS) were used. The survey data was analyzed by descriptive statistics, reliability, correlation and the mediating effect was verified by Baron & Kenny (1986)'s 3 step using SPSS 23 and sobel test. Mediating analysis indicated that the significant relationships between materialism and affective well-being and psychological well-being were reduced significantly when the external locus of control was statistically controlled. Results are meaningful with respect to overcome materialism of middle-aged woman and in the relation to other research that has explored reasons why materialism is related to lower level of affective well-being & psychological well-being.

  • The aim of this paper is to examine satisfaction of residents and preference on the outdoor space's design by multi-family housing complex scale. So we divide outdoor space into space for green land, space for physical training and play, space for walking and space for rest and landscape facilities. The major findings of this analysis are follows : Multi-family housing complex scale is the bigger, it is recognized by same ratio on specific outdoor space in housing complex that are space for green land, space for physical training and play, space for rest and landscape facilities. And space for physical training and play is found commonly into the poorest space in housing complex. Evaluation for resident's perception on outdoor space by multifamily housing complex scale shows that housing complex scale is the bigger, resident's satisfaction is the lower. That means that housing complex of large scale can't satisfy the diverse resident's demand.

  • Purpose: The study purposes were to describe the process of developing the Korean versions of the Six Dimension Scale of Nursing Performance (Six-D) and Student Nurse Stress Index (SNSI) and psychometric evaluation of the two measurements. Methods: This was a methodology study using a descriptive cross-sectional design with 51 nursing students in 4th year of university. Internal consistency reliability was assessed using Cronbach alphas. Construct validity was determined by exploring correlations among Six-D, SNSI, objective structured clinical examination (OSCE), self-efficacy and grade point average (GPA). Results: Internal consistency reliability of Six-D and SNSI was acceptable with Cronbach's ${\alpha}$ of .95 and .82. Correlation analysis to determine construct validity revealed that Six-D presented positive correlations with OSCE (r=.109~.272) and self-efficacy (r=.005~.161) and negative correlation with GPA (r=-.246~-.394), although all were not statistically significant. SNSI presented all negative correlations with OSCE (r= -.007~-.238), self-efficacy (r=-.246~-.394), and GPA (r=-.092~-.426) and were mostly statistically significant except OSCE. Conclusion: Six-D needs more evidence to confirm validity to predict observed clinical competency and theoretical relationships with self-efficacy and GPA. However, SNSI presented trends of expected relationships with relevant variables. Therefore, further research is recommended in testing validity of Six-D with other student populations.

  • In this paper, an automated segmentation algorithm is proposed for MR brain images using T1-weighted, T2-weighted, and PD images complementarily. The proposed segmentation algorithm is composed of 3 steps. In the first step, cerebrum images are extracted by putting a cerebrum mask upon the three input images. In the second step, outstanding clusters that represent inner tissues of the cerebrum are chosen among 3-dimensional (3D) clusters. 3D clusters are determined by intersecting densely distributed parts of 2D histogram in the 3D space formed with three optimal scale images. Optimal scale image best describes the shape of densely distributed parts of pixels in 2D histogram. In the final step, cerebrum images are segmented using FCM algorithm with it’s initial centroid value as the outstanding cluster’s centroid value. The proposed segmentation algorithm complements the defect of FCM algorithm, being influenced upon initial centroid, by calculating cluster’s centroid accurately And also can get better segmentation results from the proposed segmentation algorithm with multi spectral analysis than the results of single spectral analysis.
