This research investigates the design process of free-form architecture to understand the design strategy and changing factors during the development phase and the cause for them. It is aimed to foresee the changing factors from the design process and to reduce design changes. It analyzes the design changes of free-form architecture based on projects with finalized documentation or under construction in South Korea. Many free-form shapes of the free-form architectures have to be adjusted to rigid-form in order to satisfy function and be economical to build. The research finds three patterns in design changes. First, from the factors for design changes: function, constructability, design, program add/subtract, efficiency, circulation; Function and Constructability are the higher factors compared with the rest. The two are the design changes suitable for actual usage and cost savings. Second, each project has different predominant factors for design changes as the degree of free-form is different. Contrary to initial expectation, the greater the degrees of free-form of the competition scheme, the higher the rate of Function among the factors for design changes. Constructability is higher when the degree of the free-form is less than others. It means that the lower the degree of the free-form, the more properly planned the space of the building is. Last, Constructability of free-form architecture is considered during the earlier design phase than definite-form, one by which the design changes by comparing ‘Before fixed Space Program’ (BSP) and ‘After fixed Space Program’ (ASP) design changes. The research would be helpful as a reference for setting up competition guidelines to reduce trial and error during the design process.

This study analyzes the option value of flexible cropping system of smart farming with information and communication technology (ICT), which have been adopted for alternatives to traditional farming. In the study we consider two crops, paprika and tomato, that have very similar facilities in smart farming, thus no additional cost is required for switching crops. A simulation based real options approach is adopted to get the option value of flexible cropping system under uncertain market condition. Market prices of two crops are assumed as stochastic variables and proven to follow Mean Reverting Process. Results shows that the probabilities of cultivating paprika and tomato are fifty one percentage and forty nine percentage, respectively, when flexible decision making for crop selection is reflected. Farmers with smart farming change crops about 7.8 times for thirty years of business period. The option value of flexible cropping system of smart farming is 118,588 thousand won for thirty years, which is the difference between the flexible system and the system with paprika only. This implies that profit-ability analysis with option value may have positive impact on farmers’ adoption of smart farming.

Jae-Ha Jung,Na-Yon Kim,Yeseul Yang,Dansong Seo,Goeun Choi,Hyunki Hong,Taeseong Moon,Hyeong-Mok Kim,Jihee Han,Jihee Hong,Yongbaek Kim 대한수의학회 2023 Journal of Veterinary Science Vol.24 No.5

Two Domestic Korean Shorthair cats presented with dyschezia and vomiting. Computed tomography revealed a colonic mass with calcification and lymph node metastasis in case 1, and a small intestinal mass with disseminated mesenteric metastasis and calcification in case 2. Histopathology revealed intestinal adenocarcinoma with osseous metaplasia. Case 1 died two months after surgery from distant metastasis; and case 2 showed no metastasis for five months but presented with anorexia, euthanized seven months after diagnosis. Metastatic intestinal adenocarcinoma with bone formation should be considered as differential diagnosis for calcification on imaging, and lymph node metastasis at diagnosis may indicate poor prognosis.

This study selected financial indices from manufacturing industry and agricultural industry and produced their values that could be applied to agricultural accounting data in Korea. In addition, we classified farming types of rice farm based on the financial indices to suggest farm specific consulting. For the study, data from farm economy survey and agricultural production cost were used. Factor analysis and cluster analysis were applied to classify farming types. Results showed that thirteen financial indices were available within liquidity, solvency, profitability, efficiency and growth and their values specific to rice farming were calculated. Thirteen financial indices were condensed to three factors with high profitability, low return on assets/or equity and low rate of growth, and high return on asset/or equity and low liquidity and solvency. Four farming types were derived from three factors. The characteristics of four farming types with financial indices and socioeconomic data were described and some consulting suggestions for farm improvement in each farming type were suggested.

Recently, no-tillage cultivation practice of rice are receiving great attention from agricultural researchers, policy makers and farmers because it is related to environmentally friendly practice to reduce carbon and greenhouse gasses and to cope with labor shortage and rapid aging of workforce in the agricultural sector. Among the interest groups, farmers are final decision makers weather to accept or not the practice compared to other cultivation practices of rice is available to farmers, especially regarding the economic outcome under uncertainty. Fortunately, National institute of Crop Science(NICS) produced data for yields and greenhouse gas emissions from several practices including no-tillage practice with three years experiments in rice fields. This study analysis the economic outcome of several cultivation practices under uncertainty with the field data obtained from NICS from 2014 to year 2016, during which the practices include tillage, wet-direct seeding, partial tillage and no-tillage. For the analysis we introduce farmers risk preference to reflect his/her risk averse attitude and adopt stochastic dominance analysis, which are basically grounded on simulation techniques and utility function. We form empirical distribution functions and beta distribution functions for each alternative practice, where the former are based on empirical field data and latter based on the best fitted distribution functions from empirical data. The negative exponential utility function is adopted to refect farmers risk aversion coefficient with constant absolute risk aversion(CARA). This study also provides confidence premium(risk premium) that makes indifferent between the most preferred practice(the base practice) and the comparable alternatives according to the mix of risk preference and magnitude of cost saving. The premium is a kind of compensation to be given to farmers for choosing one alternative to the other alternative. The bigger the premium, the harder the alternation of alternatives from the most preferred practice(the base practice). This study is expected to be helpful to farmers decision making for adoption of cultivation practices of rice. Farmers can choose the best alternative according to their risk preference among the rankings of alternatives determined by the mix of risk preference and magnitude of cost saving. In addition, policy makers can choose any alternatives desirable to protect the environment and support the selected alternative with appropriate government programs.

We measured the effects of unit change in loss ratio evaluation on insurance premium rate and agent commission fee in Korean crop insurance. For the study, empirical data of apple and pear insurances and rice insurance from 2011 to 2018 were obtained from Agricultural Policy Insurance & Finance Service. Ten years of simulation with Copula method was performed to produce insurance premium rate, which was used for the calculation of cost saving in commission fee of eight years during the analytic periods. The results showed that the premium rate discount ranged from 2.06 percentage in pear with perils coverage to 30.4 percentage in pear with all risks coverage. The cost saving in commission fee during the eight years ranged from 511 million won in pear with all risks coverage to 10,442 million won in rice. The cost saving in pear insurance was higher in peril coverage than in all risks coverage.

Aim: The aim of this study was to explore the meaning of the experience of providing compassionate care to patients admitted to acute hospitals. Method: This study design was qualitative research that applies the evidence theory method. The participants were clinical nurses who experienced direct patient care for more than three months (N=13). The data collection was an in-depth face-to-face interview from July 2020 to February 2021. The number of interviews per participant was one time, and the interview time was 30-60 minutes, which was recorded after obtaining informed consent, and the researcher immediately transcribed and analyzed after the interview. The data analysis was used the Strauss and Corbin (2008) method. Result: The compassionate care experience of clinical nurses was derived from 78 concepts, 33 subcategories and 16 categories. The central phenomenon representing compassionate care among clinical nurses was derived from ‘holistic care that understands disease progression’. The causal conditions of this process were shown to be "immersion into the patient’s difficult feelings" and ‘sensitive awareness of the patient’s physical and emotional needs". Contextual conditions affecting the phenomenon were ‘experience a patient’s emotional vortex’, ‘workload pressure and time limits’, ‘lack of warmth and tolerance of the nurse’ and intervening conditions were "advice from colleagues’, "training through experience and learning". The interaction strategies were "recognizing emotions", "trying to communicate", priority pain control", "stay by your side by side’, and "to provide information, and the results were "positive changes in the patients", "the satisfaction and belief of a nurses", and "be burned out". Conclusion: Based on the results of this study, the ultimate consequence of compassionate care was enhancing job satisfaction and professional beliefs from the nurse"s perspective and leading to patient cooperation and positive health outcomes from the patient"s perspective. It is expected that such nurses will be utilized as the cornerstone for developing the body of knowledge related to compassion-based care.
