황종호,이창기,유호송,조강수,최영득,함원식 대한비뇨의학회 2012 Investigative and Clinical Urology Vol.53 No.6

Purpose: To assess the clinical reliability of the Bosniak IIF category and to determine the proper radiologic follow-up duration and intervals for category IIF complex renal cysts. Materials and Methods: We studied 201 patients with category IIF renal cysts from January 1996 to January 2011. Renal cyst progression to category III was defined as an increase in complexity of the cyst in follow-up radiologic studies. We monitored radiologic changes and progression of renal cysts during the follow-up period and analyzed the pathologic results of those patients who were treated surgically. Results: At a mean follow-up of 20 months, only 14 cases (7%) showed evidence of progression to stage III, with a mean time to progression of 11 months (range, 3 to 65 months). There were no significant differences in age, gender, cyst size, or change in cyst size between the progressive and non-progressive groups. Of 12 cases treated surgically, 10 cases (83.3%) showed renal cell carcinoma with pT1 stage, and there was no recurrence during postoperative follow-up of 23 months. Of the 187 patients without radiologic progression, 23 cases were treated surgically, and all of them showed benign cysts. Conclusions: The IIF category showed significant clinical reliability by a low rate of radiologic progression and a high rate of malignancy in the radiologic progressive group but a low rate of malignancy in the non-progressive group. Although it is hard to decide on a proper follow-up duration because of the variable time to progression, too frequent follow-up study seems to be unnecessary considering that most malignant cases were of a low stage.

레스토랑 고객의 불평태도, 블평의도, 불평행동에 관한 연구

황종호 대한경영학회 2003 大韓經營學會誌 Vol.16 No.1

This paper aims at examining the determinants of customers' complaint intention to fast-food restaurants and family restaurants, and providing restaurant managers and marketers the importance of customers' complaint intention. Based upon the theory of exit, voice, and loyalty and the attribution theory, we build the more comprehensive model on complaint intention. The results show that complaint attitude, perceived value of complaint, and perceived likelihood of successful complaint influence significantly to the customers' complaint intention. The complaint attitude also is influence significantly by prior experience of complaint and controllability toward complaint. The implications and limitations are discussed.

CRM 시스템과 기업의 마케팅성과간의 관계에 대한 연구

황종호,박봉규 대한경영학회 2004 大韓經營學會誌 Vol.17 No.3

The purpose of this study is to examine the relationship among CRM system, customer program, CRM characteristics, and marketing performance in hotels. Though the extant studies have been examined the relationship between CRM system and performance, the scope was limited. To fill this cap this study tries to examine the relationship among CRM system, customer program, CRM characteristics, and its marketing performance. Based upon the extant theoretical and empirical study four hypotheses have been suggested. Hypotheses testing using AMOS are conducted for 241 employees form Busan and Seoul five-star hotels during July 2003 periods. The results show that CRM system significantly influenced to CRM characteristics, but did not significantly influenced to CRM management program. The statistically significant determinants of marketing performance are CRM management program and CRM characteristics. The limitation and suggestions of this study are presented.

Effects of the Simultaneous Application of Nonlinear Frequency Compression and Dichotic Hearing on the Speech Recognition of Severely Hearing-Impaired Subjects: Simulation Test

황종호,남경원,윤성훈,김진률,육선현,홍성화,장동표,김인영 대한이비인후과학회 2015 Clinical and Experimental Otorhinolaryngology Vol.8 No.2

Objectives. The clinical effects of the simultaneous application of nonlinear frequency compression and dichotic hearing on people with hearing impairments have not been evaluated previously. In this study, the clinical effects of the simultaneous application of these two techniques on the recognition of consonant-vowel-consonant (CVC) words with fricatives were evaluated using normal-hearing subjects and a hearing loss simulator operated in the severe hearing loss setting. Methods. A total of 21 normal-hearing volunteers whose native language was English were recruited for this study, and two different hearing loss simulators, which were configured for severe hearing loss in the high-frequency range, were utilized. The subjects heard 82 English CVC words, and the word recognition score and response time were measured. Results. The experimental results demonstrated that the simultaneous application of these two techniques showed almost even performance compared to the sole application of nonlinear frequency compression in a severe hearing loss setting. Conclusion. Though it is generally accepted that dichotic hearing can decrease the spectral masking thresholds of an hearing-impaired person, simultaneous application of the nonlinear frequency compression and dichotic hearing techniques did not significantly improve the recognition of words with fricatives compared to the sole application of nonlinear frequency compression in a severe hearing loss setting.
