  • This paper examines the background and content of Thomas Jefferson's botanical garden plan for the University of Virginia. When Jefferson promoted the establishment of a botanical garden, European botanical gardens were evolving from physic gardens, and American botanical gardens were in their infancy. Accordingly, this paper compares the Botanical Garden Plan for the University of Virginia with contemporary botanical gardens. This is examined by outlining the trends of botanical gardens in Europe and the United States around the nineteenth century, analyzing their function and spatial structure. Also, Jefferson's perspective on botany, his plan, and botanical gardens are reviewed. This study found that Jefferson's project had its background in the social recognition of the importance of botany as a practical science, advancing the national economy, which was a prominent goal in late eighteenth-century Europe, and in developing networks of exchanging plants and information concerning botany and botanical gardens. Based on the botanist Correia's opinion on the role of a public botanical garden, the Botanical Garden Plan for the University of Virginia was developed by Jefferson as an action plan, including its site creation, space organization, and supplying of plants. Compared to the other contemporary botanical gardens, the University of Virginia's Botanical Garden Plan has the following characteristics. First, like European gardens in the late eighteenth century, it evolved from being a physic garden to a botanical one. As such, it emphasized botanical research and education over medicine, creating a tree garden and a plant garden. Second, it differed from many European and American botanical gardens in that it rejected decorative elements, refused to install a greenhouse, and attempted to spread practical overseas plants suitable to the local climate. This study contributes to broadening the history of botanical gardens at the turn of the nineteenth century.

  • In the Jirisan area of the Yeongnam Massif, Korea, several ductile shear zones are developed within Precambrian gneiss complex (Jirisan metamorphic rock complex). The ductile shear zones have a general NS- and NNE-striking foliation with westward dipping directions. The foliation developed in the shear zones cut the foliation in gneiss complex. The stretching lineations are well developed in the foliated plane of the shear zone, showing ENE-trend with gentle plunging angle to the ESE direction. Within shear zone, several millimetric to centimetric size of porphyroclasts are deformed strongly as a sigmoid form by ductile shearing. The sigmoid patterns of porphyroclasts in the shear zones indicate the dextral shearing. The spatial distribution of ductile shear zone is characterized by the dominant NS- and NNE-striking dextral sense in the central and eastern regions respectively. In the western part, it develops in NE-striking dextral sense which is the general direction of the Honam shear zone. The U-Pb concordant ages obtained from the two samples, the strongly sheared leucocratic gneiss, are $1,868{\pm}3.8Ma$ and $1,867{\pm}4.0Ma$, respectively, which are consistent with the U-Pb ages reported around the study area. We supposed that the ductile shearing in the study area is occurred about 230~220 Ma during late stage of the continental collision around Korea and is preceded by granitic intrusion related to subduction during 260~230 Ma, which are supported by compiling the age data from sheared gneiss, deformed mafic dyke intruded gneiss complex, and non-deformed igneous rocks.

  • The purpose of this study is to verify whether the university-based humanity leadership program is effective in improving personality, self-esteem, leadership and life satisfaction. The subjects of this study were 45 students in the experimental group and 45 students in the control group, and the control group did not participate in the leadership program. The research was conducted from September 5, 2017 to November 28, 2017. The program was conducted twice a month for a total of six sessions. To verify the effectiveness of the program, preliminary tests were conducted before the first session and then post-tests were conducted after the program. The test consisted of a questionnaire survey on personality, self-esteem, leadership, and life satisfaction. Data analysis was performed by using SPSS 24.0 for the frequency analysis and the response sample t test for determining the differences in the post-test scores of the experimental group. First, there was a significant difference in personality, self-esteem and life satisfaction. Second, positive effects were found in three domains that included honesty, self-esteem, relationships with others, leadership, popularity, and self-assertiveness. This result suggests that it is necessary to improve the satisfaction of life through the formation of relationships with other people, and with an emphasis on honesty, in the program's development and contents.

  • Objective : The purpose of this study was to examine the validity and reliability of the Korean version of Life Balance Inventory (K-LBI) and to present the relationship between life balance and sensory processing. Methods : K-LBI was constructed through forward and backward translation. Convergent validity, internal consistency, and test-retest reliability were tested for college students. To verify convergent validity, correlation analyses between K-LBI and Korean version of Perceived Stress Scale, Korean version of Satisfaction With Life Scale, and Adult Self Report-Achenbach system of empirically based assessment were performed. Split-half reliability and test-retest reliability were also obtained for reliability verification. We performed the correlation analysis between K-LBI and Korean version of Adolescent/Adult Sensory Profile. Results : A significant correlation was found between K-LBI and the scales for convergent validity. A favorable split-half reliability and test-retest reliability were calculated. The positive correlations were found between relationship life balance and sensory sensitivity/sensation avoiding quadrants. The negative correlation was found between challenges life balance and low registration. Conclusion : This study shows that K-LBI is a valid and reliable tool in Korea. It also provides an in-depth understanding of the relationship between life balance and sensory processing.

  • The relationship between the body size of species and the environment has been an active research subject for many years. Until recently, studies had focused on the relationship between the body size and environment based on the ecogeographic rule for various animal groups. In this study, we examined the relationship between body size of Hyla japonica and the habitat environment in Jeju island located at the southernmost part of the Korean peninsula. We collected H. japonica from three breeding sites, Cheonji, Bonggae, and Aewol, and measured SVL, BW, and HW of the species. We also measured the altitude, longitude, latitude, annual mean temperature, and annual mean precipitation of each site to analyze the relationship between the body size and the habitat environment. The analysis results showed that there was the clear difference of the body size according to the habitat and the body size in Aewol was significantly bigger than others, while the body size in Cheonji was the smallest. The altitude was the most important environmental variable and showed a positive correlation with body size. The body size of H. japonica increased as the altitude increased, and this results were consistent with Bergmann's rule, one of the biological laws related to body size. In conclusion, the environment could affect the body size of H. japonica, and the body size has a certain direction according to the environment.

  • The research regarding employees' job satisfaction is one of the most important indicators of their vocational adjustment or outcome. The purpose of this study is to investigate the level of job satisfaction of South Korean masseurs with visual impairments and what variables predict to this. The work satisfaction model of Social Cognitive Career Theory (Lent Brown, 2006a) was grounded. a total of 221 South Korean masseurs with visual impairments participated in this study. Multiple regression analysis indicated that as masseurs in this study experienced having a better fit with their job regarding their monetary aspects, as they felt efficacious with their massage skills, as they felt more positive, and as they considered their job duties fit their education or skills they learned, their level of job satisfaction was higher. However, fit with their organization values or cultures or how much they get social support from their family, friends, or significant others did not predict their job satisfaction. In addition, the analysis supported the existence of a moderating effect of positive affect on the relationship between subjective fit and job satisfaction, in addition to the moderating effect of social support on the relationship between work related self-efficacy and job satisfaction among study participants. Implications for policy makers, researchers, and career counselors were also provided.

  • The purpose of this study was to identify the factors affecting job satisfaction of PACU (post-anesthesia care unit) nurses in the context of job stress, organizational culture and professional identity. A total of 149 nurses participated in the cross-sectional, descriptive study suing a structured questionnaire. Job stress in pay and treatment category, innovation-oriented culture, relation-oriented culture, and professional identity were positively correlated with job satisfaction (r=.373, p<.001; r=.507, p<.001; r=.559, p<.001; r=.544, p<.001). The factors related to job satisfaction were professional identity (${\beta}=.391$, p<.001), relation oriented culture (${\beta}=.302$, p<.001), innovation oriented culture (${\beta}=.209$, p=.004), which accounted for 48.7% of the variance in job satisfaction. Professional identity was the most significant predictor of job satisfaction. Thus, in order to enhance the job satisfaction of nurses in the PACU, it is necessary to develop an education program that can improve professional identity and apply strategies for fostering relation and innovation oriented organization culture.

  • The surfgrass Phyllospadix iwatensis is native in the exposed rocky shores of the Northwestern Pacific Ocean. In Korea, P. iwatensis is mainly found on the rocky subtidal zone in the central eastern coast. In this study, to examine the ecological characteristics of P. iwatensis, we investigated changes in morphological characteristics, density, biomass, and leaf productivity as well as changes in the underwater irradiance and water temperature of its habitat monthly from August 2017 to July 2018. Underwater irradiance and water temperature showed clear seasonal changes; increases in spring and summer and decreases in fall and winter. Morphological characteristics, shoot density, biomass, and leaf productivities of P. iwatensis exhibited significant seasonal variations, increasing in winter and spring and decreasing in summer and fall months. P. iwatensis leaf productivities both per shoot and per unit area showed significant positive correlations with underwater irradiance. The average leaf productivity of P. iwatensis per area was $6.3{\pm}1.3g\;m^{-2}d^{-1}$, while minimum and maximum values were $2.4{\pm}0.3g\;m^{-2}d^{-1}$ in February 2018 and $16.4{\pm}4.4g\;m^{-2}d^{-1}$ in May 2018, respectively. The optimum water temperature for the growth of P. iwatensis in this study was between $12-13^{\circ}C$.

  • Oriental Diagnosis System(ODS) is an artificial intelligence program that utilize entered diagnosis knowledge, determine patient's disease and decide right medicine. The purpose of this study is to find a correlation between pattern Identification in Korean medicine and each sasang types(Tae-Eum and So-Yang) by analyzing ODS diagnosis result. Eventually our study secure availability of using ODS program at clinical training or developing diagnosis program. Subject of this study is 50 patients who was performed Sasang constitution diagnosis (28 patients were Tae-Eum and 22 patients were So-Yang). We analyize patient's diagnosis records by using ODS program and obtained result about pattern Identification. We used SPSS statistics 23 in analyzing the differences of the scores of Eight Principle Pattern Identification, Qi-Blood Pattern Identification, and Bing-xie Pattern Identification in each Sasang types (Tae-Eum, So-Yang). The Heat and Heat-moisture scores were significantly different(p<0.05) and Qi-Blood Pattern Identification scores were not different in each Sasang types(p>0.05). And Weight was significantly different in each Sasang types(p<0.05). It is hard to generalize the result because subject of this study was not enough and had sample speciality(tinnitus patients). However, we explained correlation between pattern Identification in korean medicine and each sasang types based on quantifiable and objective evidence system. it can be used at education of korean medicine and evidence of practice diagnosis. Futhermore, there have been no studies about anaylizing correlation between pattern Identification in Korean medicine and each sasang types using ODS program. So it is worthy of being utilized at clinical evidence data of ODS program.
