The conservation of the endangered Korean fir, Abies koreana, is of critical ecological importance. In our previous study, a yeast-like fungus identified as Aureobasidium pullulans AK10, was isolated and shown to enhance drought tolerance in A. koreana seedlings. In this study, the effectiveness of Au. pullulans AK10 treatment in enhancing drought tolerance in A. koreana was confirmed. Furthermore, using transcriptome analysis, we compared A. koreana seedlings treated with Au. pullulans AK10 to untreated controls under drought conditions to elucidate the molecular responses involved in increased drought tolerance. Our findings revealed a predominance of downregulated genes in the treated seedlings, suggesting a strategic reallocation of resources to enhance stress defense. Further exploration of enriched Kyoto Encyclopedia of Genes and Genomes pathways and protein-protein interaction networks revealed significant alterations in functional systems known to fortify drought tolerance, including the terpenoid backbone biosynthesis, calcium signaling pathway, pyruvate metabolism, brassinosteroid biosynthesis, and, crucially, flavonoid biosynthesis, renowned for enhancing plant drought resistance. These findings deepen our comprehension of how AK10 biostimulation enhances the resilience of A. koreana to drought stress, marking a substantial advancement in the effort to conserve this endangered tree species through environmentally sustainable treatment.

The purpose of this study was to analyze the stress distribution of condylar regions and edentulous mandible with implant-supported cantilever prostheses on the certain conditions, such as amount of load, location of load, direction of load, fixation or non-fixation on the condylar regions. Three dimensional finite element analysis was used for this study. FEM model was created by using commercial software, ANSYS(Swanson, Inc., U.S.A.). Fixed model which was fixed on the condylar regions was modeled with 74323 elements and 15387 nodes and spring model which was sprung on the condylar regions was modeled with 75020 elements and 15887 nodes. Six Br${\aa}$nemark implants with 3.75 mm diameter and 13 mm length were incorporated in the models. The placement was 4.4 mm from the midline for the first implant; the other two in each quardrant were 6.5 mm apart. The stress distribution on each model through the designed mandible was evaluated under 500N vertical load, 250N horizontal load linguobuccally, buccal 20 degree 250N oblique load and buccal 45 degree 250N oblique load. The load points were at 0 mm, 10 mm, 20 mm along the cantilever prostheses from the center of the distal fixture. The results were as follows; 1. The stress distribution of condylar regions between two models showed conspicuous differences. Fixed model showed conspicuous stress concentration on the condylar regions than spring model under vertical load only. On the other hand, spring model showed conspicuous stress concentration on the condylar regions than fixed model under 250N horizontal load linguobuccally, buccal 20 degree 250N oblique load and buccal 45 degree 250N oblique load. 2. Fixed model showed stress concentration on the posterior and mesial side of working and balancing condylar necks but spring model showed stress concentration on the posterior and mesial side of working condylar neck and the posterior and lateral side of balancing condylar neck under vertical load. 3. Fixed model showed stress concentration on the posterior and lateral side of working condylar neck and the anterior and mesial side of balancing condylar neck but spring model showed stress concentration on the anterior sides of working and balancing condylar necks under horizontal load linguobuccally. 4. Fixed model showed stress concentration on the posterior side of working condylar neck and the posterior and lateral side of balancing condylar neck but spring model showed stress concentration on the anterior side of working condylar neck and the anterior and lateral side of balancing condylar neck under buccal 20 degree oblique load. 5. Fixed model showed stress concentration on the anterior and lateral side of working condylar neck and the posterior and mesial side of balancing condylar neck but spring model showed stress concentration on the anterior side of working condylar neck and the anterior and lateral side of balancing condylar neck under buccal 45 degree oblique load.. 6. The stress distribution of bone around implants between two models revealed difference slightly. In general, magnitude of Von Mises stress was the greatest at the bone around the most distal implant and the progressive decrease more and more mesially. Under vertical load, the stress values were similar between implant neck and superstructure vertically, besides the greatest on the distal side horizontally. 7. Under horizontal load linguobuccally, buccal 20 degree oblique load and buccal 45 degree oblique load, the stress values were the greatest on the implant neck vertically, and great on the labial and lingual sides horizontally. After all, it was considered that spring model was an indispensable condition for the comprehension of the stress distributions of condylar regions.

Many people get plenty of information from World Wide Web, and the study of the factors that affect on reading task on web browser is presenting important issue. But domestic studies on legibility of Korean on web environment were relatively poor and the study about suitable text layout for skimming wasn't carried out also. At this point, this study was performed to investigate the effects of two types of reading, three levels of line length, and three levels of interlinear spacing on comprehension and reading rate when subjects read the materials on web browser. Reading speed, error rate, subjective preference and SACL(Stress and Arousal Checklist) evaluation were measured to evaluate the effects. Eighteen volunteer subjects participated in eighteen web document sessions with two different reading types, three different line lengths, and three different interlinear spacings. Statistical results from objective and subjective evaluations indicate that 50 characters per line of line length and 100 percents of interlinear spacing improved reading rate, overall error rates were reduced when reading normally, and SACL measures were increased at fast reading type. Consequently, in order to design text layout to retrieve information in WWW environment effectively, just applying guidelines of traditional printed material is not proper. Therefore, it is effective to consider reading type, line length, and interlinear spacing. Implications of these results and suggestions for the further study are also addressed.

The article explores linguo-stylistic influence markers in essayistic texts. The novelty of this investigation is provided by its perspective. Essayism is looked at as a style of thinking and writing and studied as a holistic philosophical and cultural phenomenon, as a revalent form of comprehension of reality that features non-lasting author's judgements and enhancement of the author's voice in the text. Based on the texts by V. Rosanov, G.K. Chesterton, and D. Dontsov, the remarkable English, Russian, and Ukrainian essay-writers of the first party of the 20th century, the article tracks the typical ontological-and-existentialist correlation at the content, stylistic, and semantic levels. It is observed in terms of the ideas presented in the texts of these publicists and the lexicostylistic markers of the influence on the reader that enable these ideas to implement. The explored poetic syntax, key lexemes, dialogueness, intonational melodics, specific language, free associations, aphoristic nature, verbalization of emotions and feeling in the psycholinguistic form of their expression, stress, heroic elevation, metaphors and evaluative linguistic units in the ontological-and-existentialist aspects contribute to extremely delicate and demanding nature of the essayistic style. They create a "lacework" of unpredictable properties, intellectual illumination, unexpected similarity, metaphorical freshness, sudden discoveries, unmotivated unities.

The comprehension and structural modeling of masonry constructions is fundamental to safeguard the integrity of built cultural assets and intervene through adequate actions, especially in earthquake-prone regions. Despite the availability of several modeling strategies and modern computing power, modeling masonry remains a great challenge because of still demanding computational efforts, constraints in performing destructive or semi-destructive in-situ tests, and material uncertainties. This paper investigates the shear behavior of masonry walls by applying a plane-stress FE continuum model with the Modified Masonry-like Material (MMLM). Epistemic uncertainty affecting input parameters of the MMLM is considered in a probabilistic framework. After appointing a suitable probability density function to input quantities according to prior engineering knowledge, uncertainties are propagated to outputs relying on gPCE-based surrogate models to considerably speed up the forward problem-solving. The sensitivity of the response to input parameters is evaluated through the computation of Sobol' indices pointing out the parameters more worthy to be further investigated, when dealing with the seismic assessment of masonry buildings. Finally, masonry mechanical properties are calibrated in a probabilistic setting with the Bayesian approach to the inverse problem based on the available measurements obtained from the experimental load-displacement curves provided by shear compression in-situ tests.

Objectives : The purpose of this research is to understand melanin with both Korean and Western medicine.Methods : We investigated the comprehension of melanin in both western and Korean medicine through literature review and studied relationships between melanin and five viscera(五臟), especially liver(肝), spleen(脾), kidney(腎). We Also studied representative pigmentary disorders(melasma, vitiligo) in western and Korean medicine to figure out how to understand pigmentary disorders in oriental medicine.Results : The results are as follows. 1. Melanin is associate with liver, because free coursing(疎泄) function of liver is the origin of transport melanin to keratinocyte from melanocyte. Also, melanogenesis factors like MITF and CREB are closely associated with liver and pigmentary disorders occur frequently after stress conditions or women. 2. Melanin is absorbed and scattered in keratinocytes by the function of spleen. Pigmentary disorders result from failure of spleen and formation of phlegm-retained fluid(痰飮). 3. Kidney essence(腎精) is the origin of melanin formation. In addition, corticosteroid, the major hormone of melanogenesis is secreted by adrenalin and adrenalin belongs to kidney(腎) in Korean medicine. 4. Melasma is created by disorder of melanin transport and absorbtion, so melasma is associated liver (肝) and spleen(脾). Therefore the treatment for melasma may focus on improvement function of liver and spleen. 5. The destruction of melanocyte or abnormal melanogenesis by disorder of the immune system, metabolic and affective disorders can make vitiligo, so vitiligo is associated with liver and kidney which are major part of melanin formation. Therefore the treatment of vitiligo can focus on improvement function of liver(肝) and kidney(腎).Conclusion : We compared Korean and western medicine to understand melanin. We also interpreted the mechanism of melanin and pigmantary disorders in western medicine and considered the relationship with visceral manifestation theory(臟象論) in traditional Korean medicine. Further studies are needed to apply comprehension of melanin to clinical stage.

This study was conducted in order to identify factors influencing maternal-fetal attachment among pregnant women, considering the factors presented in Mercer's theory: Becoming a Mother(pregnancy stress, self-esteem, dyadic adjustment, sense of mastery, antepartum stress). The data was collected through structured questionnaires from 140 pregnant women who visited the obstetric clinic and public health centers in a metropolitan area to have prenatal tests from August 23th to November 25th 2014. The data were analyzed by SPSS 20 software using descriptive statistics, the t-test, ANOVA, the Pearson's correlation coefficients and a stepwise multiple regression. The results were as follows: Maternal-fetal attachment in the group of pregnant women under 30 years of age was significantly higher than that in the group of over the age of 31(t=2.79,p=.004). Primiparas had higher maternal-fetal attachment than multiparas(F=3.27, p=.041). There was a negative correlation between pregnancy stress(r=-0.22, p=.009) and maternal-fetal attachment. Self-esteem (r=0.45, p<.001), dyadic adjustment(r=0.42, p<.001), sense of mastery(r=0.24, p=.005) and maternal-fetal attachment were, however, positively correlated. It was found that self-esteem, dyadic adjustment and age were some of the factors influencing maternal-fetal attachment among pregnant women. These variables explained 26.1% of the variance in maternal-fetal attachment. Findings of this study indicate needs for comprehension and assessment of self-esteem and dyadic adjustment in pregnant women through prenatal tests. Also, the intervention programs to improve maternal-fetal attachment among older mothers should be developed and implemented.

This study tried to suggest the development of a writing education model for Christian Universities based on both Hobbs' media education model and Vanhoozer's media text analysis model. This model consists of 6 steps- Christian worldview establishment, access, analysis and evaluation, creation, reflection and social action. This was developed in order to be applied for the class "reading and writing" of liberal arts. Also, this is an appropriate model for media text writing education aiming at an alternative creation activity through a critical comprehension of the complex texts consisting of sounds, images, letters and so on. Furthermore, this is designed to train the capable persons having intelligence, character, and spirituality balanced, whom the education of Chrisitian universities aims at. Finally, this model pursues the student-friendly and amalgamative text writing appropriate for a new era and has an advantage to raise the power of various forms of letter writing which all the universities should stress as well.

Purpose: This study was conducted to ascertain the effectiveness of horticultural therapy by analyzing researches on horticultural therapy applied to elderly Koreans. Methods: We evaluated 401 research papers including dissertations on horticultural therapy applied to elderly Koreans from Jan. 2000 to Feb. 2016. We reviewed the appropriate 12 papers among them for the final analysis. Results: Horticultural therapy had physiological and psychosocial effects. First of all, it showed the physiological effects of reducing stress hormones. Outdoor horticultural therapy improved the gross motor movements of the body. Indoor horticulture therapy improved delicate cognitive & operating functions. Second, horticultural therapy showed the psychosocial effects of reducing depression and improving cognitive functions, language abilities, comprehension, daily activity, life satisfaction and sociality. But the effects appeared differently dependent on the implementation protocol & period of horticultural therapy, as well as the professionalism of the therapists. Therefore, if horticultural therapy were to be administered through nursing, it should be based on its key principle, in other words, the principle of action-interaction-response of horticultural therapy. Conclusion: The results of this study will be useful for developing therapeutic interventions through nursing. Also they will be helpful in applying horticultural therapy programs in nursing practice.
