This study was conducted to find the important factors which co uld International Herb Expo 2004. In addition, in this study, we tr ied to extract the representative features from customer groups. To these purposes, we conducted Factor Analysis, Cluster sis, and Multiple Regression. The major fi ndings and marketing implicati ons could be summarized as follows: First, finally 5 factors Learning, Subjective Norms, , Usefulness, and Experience were extracted as the influential factors. Second, the 5 factors were revealed to hav e very strong relations with the Customer Satis on within the significance level of 0.01. Experience was revealed as an impor tant factor improving the Customer Satisfaction and Intention to Re-attend. T h i r d , cluster analysis identifi Belonger, Achiever, and Player. Then the Player was found to be the Opinion Leader. Fourth, 김진성서비스경영학회지 제8권 제1호 2007년 3월 216Usefulness was revealed as the most important factor to improve C u s t o m e r Satisfaction and Intention to Re-attend. 요인별 평균은 “체험성(3.85) > 학습성(3.76) > 교통/시설(3.51) > 유익성(2.99) > 주관적 규범(2.90)” 순서로 나타났다. 이 결과를 통해서, 방문자들이 느끼는 만족도 영향요인의 중에서 “체험성”이 가장 높다는 것을 알 수 있다.5.3. 군집분석요인분석에서 도출한 5개 영향요인을 기준으로 K-평균 군집분석을 통해, 남원 세계허브산업엑스포 참가자들을 3개의 그룹으로 분류하였다.

Purpose: We aimed to investigate the benefit of a screening tool in selecting head-injured children who can potentially cooperate with computed tomography (CT). Methods: The study population consisted of head-injured children aged 36 months or younger who visited the emergency department (ED) and underwent CT from January 2013 through December 2020. Procedural sedation and analgesia (PSA) using per os chloral hydrate or per rectal thiopental was implemented to children presumed less cooperative for CT as per a clinical screening tool for cooperative candidates for CT (e.g., ability to lie still on bed for 10 seconds without a guardian). According to the PSA and the first attempt success of CT, we compared baseline characteristics, CT findings, clinically important traumatic brain injury, ED length of stay (EDLOS), and ED disposition. Results: Among the 247 children, PSA was used in 102 (41.3%). The PSA group showed a higher proportion of 3-36 months of age (PSA, 96.1% vs. non-PSA, 82.8%; P = 0.001) and longer median EDLOS (PSA, 127.0 [interquartile range, 101.0-172.0] vs. non-PSA, 85.0 minutes [63.0-130.0]; P < 0.001). The number of children undergoing the first attempt success was 213 (86.2%) without a difference in both groups (PSA, 84.3% vs. non-PSA, 87.6%; P = 0.645). In the 213 children, the implementation of PSA was associated with longer median EDLOS (PSA, 121.0 [99.0-156.0] vs. non-PSA, 77.0 minutes [60.0-122.0]; P < 0.001). In the non-PSA group (n = 145), the first attempt failure was associated with the presence of skull fracture (success, 7.1% vs. failure, 27.8%; P = 0.009). Conclusion: This study suggests a potential benefit of the screening tool in selecting cooperative candidates for CT, i.e., those who could forgo PSA using oral chloral hydrate or per rectal thiopental, in young children with head injury

The RO(Reverse Osmosis) desalination plants are energy intensive and require fine tuned components. Therefore, a good control design is necessary to maintain water production costs at acceptable level and to elevate the plant availability, particularly in legions with high water scarcity. Therefore, the advanced techniques of control will be useful for efficiency of RO plant. Here, the controller model proposed by is utilized to design a robust improved PID controller. Therefore, a robust control of RO plant is studied utilizing the new structure of PID controller with nonlinear gain in this paper. This structure is composed with new type of integral control action. The conventional PID controller is limited because of its poor performance due to actuator saturation and nonlinear effects. In order to resolve these problems, a novel control scheme is proposed by integrating improved integral control and nonlinear gain. The performance and stability of newly proposed PID technique is compared with those of conventional ones via simulation in terms of Bode plot, etc.

이 연구는 생활체육지도자 배치사업 운영문제점과 금후과제가 무엇인지 이유를 밝히는 것이 목적이다. 지금까지 단순 생활체육지도자 배치사업 운영시스템에 대한 관심 차원에 머물렀다는 문제제기를 통해 본 연구는 실질적인 문제점, 운영방안, 개선점 요인을 밝혀보려고 노력했다. 이를 위해 연구 참여자는 현재 생활체육지도자 5년 이상 경력을 가진 지도자, 생활체육 배치사업 담당자 및 팀장, 부서장으로 구성되었으며 비확률적 표집의 하나인 유목적 표집법으로 12명 선정하였다. 그 결과 생활체육지도자 배치사업 운영시스템 금후 과제는 귀납적 범주분석을 실시한 결과 총 11개의 중영역과 5개의 대 영역을 발견 할 수 있었다. 첫 번째 요인으로는 계약직 신분 한계, 근무환경 개선, 복리후생, 복무개선 ‘정규직 신분전환’이 전체 반응 532개 중 205개(38.5%)로 도출되었다. 두 번째는 정규직․ 무기계약직 전환에 따른 전문성 역량 강화, 자기계발, 안전관리 강화로 전문성 역량개발 반응 수가 133개(25%), 대 영역으로 위치되었고, 세 번째 빈도를 보인 평가시스템 개선, 평가 불공정, ‘평가시스템 개선’ 90개(16.9%)로 대변되었다. 네 번째는 수혜자 관리, ‘수혜자 데이터 관리’로 전체 반응 중 71개(13%)를 차지하였다. 마지막 요인은 체감형 홍보는 ‘생활체육지도자 배치사업 홍보’로 33개(6.2%)요인으로 작용한 것으로 본 연구결과 밝혀졌다. The purpose of this study is to clarify the reasons for the problem of future business assignments and future assignments. Edge Edge Edge server can be used for more advanced settings. New versions, new versions, new versions, and new versions added from May 1 to December 5 were added. The first factor was derived from 205 out of 532 responses (38.5%): contract status limit, workplace environment improvement, welfare benefits, and service improvement “regular job status change”. The second is a regular job. Improving the evaluation system which showed the frequency of the third time, the number of responses of professional development was 133 (25%) in order to strengthen professional skills by indefinite contract change, self-development, and strengthen safety management. Unfair evaluation, "improved evaluation system" was represented by 90 (16.9%). The fourth was beneficiary management, “beneficiary data management”, accounting for 71 (13%) of the overall response. The last factor is that the results of this study revealed that the sensation-type public relations acted as 33 factors (6.2%) in "Promotion of placement of life and physical education leaders".
