페르소나 기법을 활용한 공공기관 데이터기반행정의 활성화 예측을 위한 사례연구
박기남 한국정보시스템학회 2025 정보시스템연구 Vol.34 No.2
Purpose This study focuses on the fact that Institution A's data-based administration is perceived and responded to differently by employees with diverse needs and behaviors. Through this, we would like to establish persona-based scenario planning goals and propose guidelines to resolve various data-related issues related to Institution A. Design/methodology/approach As an attempt to explain the changing aspects of future society through various possibilities, the scenario technique is meaningful in that it unfolds the trends of future change through vivid stories. The Persona-based scenario technique presented in this study is a method that has been used in the product and service design field in situations where it is difficult to realistically survey all users due to constraints such as resources and time. Findings Therefore, this study defines all employees within Institution A as major service users of data-based administration, systematically classifies and specifies the types of data analysis and utilization that employees want to perform, identifies their specific needs, and explores future scenarios.

Many different statistical and artificial intelligent techniques have been applied to improve the predictability of credit rating. Hybrid models and systems have also been developed by effectively combining different modeling processes of combining the outcomes of individual models. In this paper, we introduced the rough set theory and developed a hybrid credit rating system that combines individual outcomes in terms of rough set theory. An experiment was conducted to compare the prediction capability of the system with those of other methods. The proposed system based on rough set method outperformed the others.
Nationwide Multicenter Survey for Current Status of Endoscopic Thyroidectomy in Korea
박기남,조상혁,이승원 대한이비인후과학회 2015 Clinical and Experimental Otorhinolaryngology Vol.8 No.2
Objectives. We evaluated the current status of endoscopic thyroidectomy procedures in Korea in terms of indications, contraindications, advantages, disadvantages, complications, and limitations of each approach. Methods. An email survey, consisting of 15 questions, was sent to 29 experienced endoscopic thyroidectomy surgeons. Results. The most commonly used approach was the gasless transaxillary approach (66.7%), followed by the bilateral axillo-breast approach with gas insufflation (23.8%). The most common indication was less than 1 cm, single papillary thyroid cancer. The role of endoscopic thyroidectomy is not still established; some consider it a novel procedure (34.8%), others a transition to robotic thyroidectomy (34.8%). Conclusion. Our results shed light on the general consensus of opinions about endoscopic thyroidectomy, such as the advantages, disadvantages, complications, limitations, and even its future role.

Objectives. This study prospectively evaluated postthyroidectomy syndrome (PTS) through objective and subjective voice changes following thyroidectomy of open vs. endoscopic thyroidectomy. Methods. A prospective clinical trial (SCHBC IRB 09 26) was performed from Jan 2008 to Aug 2010 to compare the open thyroidectomy (OPEN group) and endoscopic thyroidectomy (ENDO group). Of the 110 patients, 75 completed the evaluation before and 1 and 6 months after surgery. Subjective parameters included perceptual analysis (GRBAS [grade, roughness, breathiness, asthenia, and strain] scale), stroboscopic or flexible fiberscopic analysis, voice handicap index, and 5-point visual analog scales for vocal fatigue, singing difficulty, difficulty with high-pitch phonation, and neck discomfort. Objective parameters included acoustic, aerodynamic analysis and the electroglottograph. Results. For the ENDO group (n=36), the operation time was longer than in the OPEN group (n=39; P<0.01). For the OPEN group, two objective and five subjective parameters were worse 1 month postoperatively; of these, two subjective parameters persisted for 6 months (P<0.05). For the ENDO group, three objective and six subjective parameters were worse 1 month postoperatively, and three of the subjective parameters persisted 6 months postoperatively (P<0.05). Conclusion. PTS really exists following simple thyroidectomy and are very common for both OPEN and ENDO groups. Most of the parameters improved gradually over time, but some subjective changes persisted 6 months postoperatively.
