Background: The purpose of this study was to investigate the association between external medical service use and the characteristics of Chungcheongnam-do patients. We aimed to provide evidence of external medical service use enhance the healthcare delivery system in Chungcheongnam-do. Methods: We used the Health Insurance Cohort DB 2.0 of 2016-2019, and 2,570,439 patients were included in the study. Multivariate logistic regression and multinomial logistic regression were used to identify the association between external medical service use and each patient characteristic. Generalized linear model was used to identify the association between medical costs and external medical service use area. Results: During the study period, 32.2% of inpatients and 12.5% of outpatients had external medical service use in Chungcheongnam-do. In comparison to patients living in Cheonan and Asan, the odds ratio (OR) for external medical services use was higher across all regions. Specifically, hospitalized patients from Gyeryong, Nonsan, and Geumsan (OR, 116.817) and Gongju, Buyeo, and Cheongyang (OR, 72.931) demonstrated extremely high likelihood of external medical service use in the Daejeon area. Furthermore, compared to medical expenses incurred within Chungcheongnam-do, patients with external medical service use in the capitol area (outpatient=17.01%, inpatients=22.11%) and Daejeon area (outpatient=16.63%, inpatients=15.41%) spent more on healthcare services. Conclusion: This study found the evidence of external medical service use among Chungcheongnam-do patients. Further study should be conducted taking into account variables including satisfaction of local medical services, different types of patient diseases, and others. The study's findings may serve as a foundation for policy proposals aimed at ensuring the financial stability of our health insurance system, ensuring the efficient delivery of medical care, and localization of medical care.

The purpose of this study was to explore practical meanings of convergence education and to seek ways of implementing it in school science education. The study adopted focus group interview method in order to elicit science teachers' perceptions and practical knowledge related to various ways of integrating educational aims and contents from the perspectives of science education. Two focus group interviews were held with four science teachers with the themes of the concept and potential of convergence education, and the implementation and systemic support, respectively. The qualitative data was analyzed by deriving major themes comprising teachers' perception on convergence education: they are 1) related concepts and rationales, 2) contents, methods, and assessment, 3) the characteristics of the science subject that make it suitable for convergent education, 4) teacher perception and professionalism required for implementing convergent education, and finally 5) environmental conditions for putting the idea into practice. Based on this result, the study discusses conceptual and practical issues for implementing convergence education in ways that contribute to overcoming the problems of the traditional educational system and reorienting science education towards the future society.

This paper presents optimized searching technique to improve the performance of H.264/AVC. By using the proposed forward and backward searching algorithm, redundant cycles of latency for data reordering can be removed. Furthermore, in order to reduce the total number of execution cycles of CAVLC encoder, early termination mode and two stage pipelined architecture are proposed. The experimental result shows that the proposed architecture needs only 36.0 cycles on average for each $16{\times}16$ macroblock encoding. The proposed architecture improves the performance by 57.8% than that of previous designs. The proposed CAVLC encoder was implemented using Verilog HDL and synthesized with Magnachip $0.18{\mu}m$ standard cell library. The synthesis result shows that the gate count is about 17K with 125Mhz clock frequency.

Volatile flavor components of Codonopsis lanceolata were extracted by gas co-distillation (GCD), solvent extraction/fractionation (SEF), and headspace sampling (HSS) methods. The extracts were analyzed by dual-capillary gas chromatography-retention index (GC-RI) and gas chromatography-mass spectrometry(GC-MS). The two extracts prepared by SEF and HSS gave more similar fragrance to the Codonopsis lanceolata than the GCD extract. The GC profiles of the SEF and HSS extracts were similar to each other except for differences in peak areas. The extract prepared by SEF gave a sweet note while the extract prepared by HSS gave a green note. The GCD extract began to give a burnt note of herb medicine with prolonged distillation. Rapid extraction of flavor components from Codonopsis lanceolata was possible in several short steps by SEF and HSS methods compared to GCD. GC-MS and GC-RI were used for peak identification. GC-RI was more effective for identification of isomers, and polar FFAP column was more suitable for identification of polar compounds. From Codonopsis lanceolata we identified 35 volatile flavor constituents, 24 of which have not been previously reported by simultaneous distillation extraction method $^{(5)}$. trans-2-Hexanal, cis-3-hexen-1-ol, trans-2-hexen-1-ol, and hexanol were considered key components of the green note and 1-octen-3-ol, the component of the fresh note. Esters, including amyl propionate, seem to be responsible for the sweet note particular to Codonopsis lanceolata.

This paper presents optimized searching technique to improve the performance of H.264/AVC. The proposed CAVLC encoder uses forward and backward searching algorithm to compute the parameters. By zero-block skipping technique and pipelined scheduling, the proposed CAVLC encoder can obtain better performance. The experimental result shows that the proposed architecture needs only 66.6 cycles on average for each $16{\times}16$ macroblock encoding. The proposed architecture improves the performance by 13.8% than that of previous designs. The proposed CAVLC encoder was implemented using VerilogHDL and synthesized with Megnachip $0.18{\mu}m$ standard cell library. The synthesis result shows that the gate count is about 15.6K with 125Mhz clock frequency.

This study is to study Adler's individual psychology and to study the counseling process and counseling techniques based on the counseling theory derived there. The progress of Adler's consultation process is first, and the relationship formation phase is the phase of seeking equal and mutually cooperative relations working as active partners toward agreed objectives between the counselor and the counsellor. Second, the lifestyle search phase is an important goal to understand lifestyle and how lifestyle affects life's task. Third, the insight phase is the one that has insight. Fourth, it is carried out in the financial direction (transformation of behavior). Adler's counseling techniques include general techniques and special techniques, and general techniques include promptness, advice, encouragement, paradoxical intentions, demonstration of poetry, and role play. Special techniques include pressing a doorbell, spitting on a physician's soup, Midas technique, entertaining others, avoiding low-quality children and self-restraint. In conclusion, individual psychological counseling is based on growth model, not medical model, and has more interest in re-education and re-lighting healthy individuals and societies than on the aspect of treatment. Therefore, it applies to various areas such as child guidance centers, parent-child counseling, marital counseling, family counseling, group counseling and treatment, personal counseling for children and adolescents, cultural conflicts and mental health campaigns.

This research is a theoretically grounded empirical study aimed at shedding light on the policy evolution of Technology Park(TP) in term of historical institutionalism in South Korea for the 16 years. The study analysed the evolution of TP, and the empirical fieldwork was completed in two regions, Gyeongsangbuk-do ana Daegu City. Historically the policy can be divided into three periods being affected by endogenous and exogenous impact. This research found that the functions of local TPs changed as following: six functions decided by central governments ${\rightarrow}$ added the role of supporting regional innovation ${\rightarrow}$ comprehensive support for small & medium-sized enterprise. Analysis of the empirical study reveals significant findings: first, the relationships between central government and local actors which was built in the quickening period have been path dependency. Second, the functions of local TPs were evolved with the characteristics of layering and reorientation of the institutions. Thirdly, there were some differentiation between the two regions because of the milieu, though the central government had the power deciding the functions.

This study is a qualitative study in which a focus group interview is applied to explore nursing students' perception of blended learning. 21 students in the 4th grade of nursing department were divided into 4 groups to collect data through interviews and content analysis was conducted. As a result of the study, it was categorized into four topics: 'Application and operation that are not thoroughly prepared', 'Loss of direction and departure from learning', 'One-way listening', and 'Convenience'. Students were satisfied with blended learning which is free from time and space constraints and repetitive, but felt inadequacy and unsatisfactoriness about quality of online contents, system, and preparation for applying blended learning. In order to apply blended learning in the future nursing classes, high-quality online content should be developed based on the effective design of online and offline classes considering the curriculum, and a systematic, administrative, financial, and institutional foundation to support online course should be prepared. In addition, a support system should be created to guide students' self-directed learning activities in online classes of blended learning.
