Laryngomicrosurgery is common procedure applying to benign laryngeal lesion. Suspension of the laryngoscope is a vital component of Laryngomicrosurgery. Suspension laryngoscopy allows for bimanual surgery and a stable operating platform. Little information is known about oropharyngeal & vocal fold complications of suspension laryngoscopy. Because laryngomicrosurgery is dependent upon suspension laryngoscopy, surgeons should fully understand the risks of suspension laryngoscopy to properly educate and care for patients undergoing suspension laryngoscopy. That is problem to allow otolaryngologist is embarrassing, for voice restoration surgery are not satisfied with the results. The authors reviewed mechanical and phonological complications after laryngomicrosurgery.

As interests in the management of government-owned corporation rise, in these days, debt reduction and normalization of management of those companies have been proceeding under the lead of government. At this point, it is very important to seek internal marketing method for improvement of internal employees’ satisfaction, loyalty and organization performance. This study analyzes impact of factors of internal marketing effect on organization satisfaction, loyalty and organization performance in the context of the domestic public companies, the Korea Electric Power Corporation (KEPCO) and the Korea Water Resources Corporation (K-WATER)"s employees empirically. There are some significant differences between the two publics. It is proved that delegation of the authority influences on internal satisfaction and organization performance in the case of KEPCO, and education and training influence on internal satisfaction and organization performance in the case of K-WATER. On the other hand, in the case of K-WATER, any internal marketing factors don’t influence on loyalty. The results of this study show somewhat different characteristics depending on the characteristics of firm, however, it is expected that this study can be very useful in regards to similar public enterprises or businesses.

The vibratory or phonating surface of the human vocal folds is a complex layered structure. Benign vocal fold lesions arise primarily within the lamina propria of the vocal folds and produce dysphonia by disrupting the normal layered architecture of the phonating surface. Therefore, treatment is aimed at excision of the lesion with restoration of the normal layered architecture. The core principle of the Microflap approach is that conservative removal of submucosal pathology with preservation of overlying normal epithelium and superficial lamina propria. Microflap approach is an essential component of most phnomicrosurgical procedures and is a challenging surgical task that requires patience, appropriate instrumentation, surgical skill, and experience. The authors reviewed surgical principles of Microflap technique, instrumentation and surgical tips that could be useful for the beginners who tried to try Microflap technique for the treatment of benign vocal fold mucosal lesions.

본 연구는 소비자의 제품에 대한 태도가 만족도와 충성도에 어떠한 영향을 미치는지를 실증분석 한 것이다. 먼저, 제품에 대한 태도가 고객만족에 영향을 미치는지, 그리고 이 영향력이 PB(Privat Brand, 유통업체 브랜드)와 NB(National Brand, 제조업체 브랜드)에 따라 다른 효과를 보이는 조절기능이 있는지를 분석하였다. 다음으로는 고객만족이 고객충성도에 영향을 미치는지 검증하였다. 이러한 분석을 위해 거위털 침구류라는 특정상 품을 분석대상으로 하여 진행하였다. 203명의 소비자를 대상으로 조사한 데이터를 구조방정식 모형을 이용하여 분석해 본 결과, 소비자의 제품에 대한 태도는 소비자 만족에 정(+)의 영향을 미쳤으며, 이 때 PB와 NB에 따라 그 영향력이 다르게 나타나서 브랜드의 조절효과가 존재하는 것으로 분석되었다. 또한, 고객만족은 고객충 성도에 정(+)의 영향력이 있는 것으로 분석되었다. 본 연구결과를 통해 브랜드의 차별화를 소비자에게 인식시키는 것이 중요함을 알 수 있었다. 보다 구체적으로는, NB 업체로 하여금 소비자에게 PB와 차별화된 NB만의 분명한 브랜드 인식을 소비자에게 심어주기 위한 전략 수립이 필요함을 시사해 준다. 이에 반해, PB업체는 NB만큼의 호의적인 제품태도를 만드는 노력을 기울여야 할 것으로 보인다. This study is designed to identify the relationship between consumers’ product attitude, customer satisfaction, and loyalty. In detail, the research aims to test three hypotheses. The first hypothesis is that consumers’ product attitude influences customer satisfaction. The second is that customer satisfaction influences loyalty. The third is that there is a moderating effect of brand type (NB (national brand) vs. PB (private brand)) in the first hypothesis. Our selected goods sample was composed of goose down comforters, and we adopted SEM (structural equation model) methodology using AMOS. We found that our research model proved to be valid for the measurements made during this research. Our results confirmed that all three hypotheses could be accepted with statistical significance. In the third hypothesis test, there was a difference of influence between PB and NB. In particular, for NB the influence of consumers’ product attitude on customer satisfaction was found to be higher than for PB. Therefore, we conclude that it is necessary to try to pay greater attention to consumers’ product attitude in the case of PB. The findings set out in our paper provide a good guideline as to improving strategic capabilities in NB and PB firms, respectively.

Background and Objectives : The purpose of this study was to compare the usefulness of Cepstral peak prominence (CPP) with parameter of Multiple Dimensional Voice Program (MDVP) in evaluating unilateral vocal fold paraylsis patients with subjective voice impairment. Materials and Methods : From July 2014 to August 2016, 37 patients with unilateral vocal fold paralysis who had been diagnosed with unilateral vocal fold paralysis and had received two or more voice tests before and after the diagnosis were evaluated for maximum phonation time (MPT), MDVP and CPP. Respectively. Voice tests were performed with short vowel /a/ and paragraph reading. Results : The CPP-a (CPP with vowel /a/) and CPP-s (CPP with paragraph reading) of the Cepstrum were statistically negatively correlated with G, R, B, and A before the voice therapy. Jitter, Shimmer, and NHR of MDVP were positively correlated with G, R, B. Jitter, Shimmer, and NHR of the MDVP were significantly correlated with the Cepstrum index. G, B, A and CPP-a and CPP-s showed a statistically significant negative correlation and a somewhat higher correlation coefficient between 0.5 and 0.78. On the other hand, in MDVP index, there was a positive correlation with G and B only with Jitter of 0.4. Conclusion : CPP can be an important evaluation tool in the evaluation of speech in the unilateral vocal cord paralysis when speech energy changes or the cycle is not constant during speech.

Background and Objectives : The purpose of this study was to classify patients with unilateral vocal fold paralysis according to their fixed location and to analysis the effects of two treatment methods by early voice therapy and injection laryngoplasty. Materials and Methods : Twenty patients who were classified as full abduction and slight abduction according to the position of paralysis were treated injection laryngoplasy, and 23 patients were treated by voice therapy. Twenty patients were treated injection laryngoplasy and 23 patients were treated voice therapy. Results were evaluated by acoustic analysis, electroglottography, cepstrum analysis before and after therapy. The voice therapy was conducted by improving the larynx movement and glottal contact, whilst removing hypertension of the supraglottic and use the breathing. Results : Significant improvement was found in the acoustic parameter, cepstrum parameter, and EGG before and after treatment in both groups. There was no significant difference between the two groups when compared before and after treatment to compare the effects of injection laryngoplasty and voice therapy. Conclusion : The initial treatments for unilateral vocal cord paralysis are injection laryngoplasty and voice therapy. however, there is no precise standard about which method should be applied first. Therefore, in this study, we tried to classify patients according to their paralysis position and then apply two methods. The results of this study suggest that voice therapy and Injection laryngoplasty at the initial stage is a very useful method to improve voice quality of vocal fold paralysis and improve laryngeal function.

갑상선 절제 술 후 기능적 음성장애의 공기역학적 특징과 음성치료 중재

이창윤,안수연,장현,정희석,손희영,Lee, Chang-Yoon,An, Soo-Youn,Chang, Hyun,Jeong, Hee Seok,Son, Hee Young 대한후두음성언어의학회 2015 대한후두음성언어의학회지 Vol.26 No.1

Background and Objectives:The objective of this study was to investigate the features of post-thyroidectomy subjective voice disorder by Voice Handicap Index (VHI) and Voice Symptom Scale (VOISS) through aerodynamic analysis and to investigate the appropriate voice therapy intervention. Materials and Methods:Twenty post-thyroidectomy patients who had no recurrent laryngeal nerve paralysis through laryngeal stroboscopy were enrolled for this study. Acoustic and aerodynamic evaluations were performed before operation, 2 weeks and 3 months after operation. Subjective voice evaluation was performed by VHI and VOISS. Aerodynamic evaluation was compared and analysed by maximum phonation time(MPT), phonation threshold pressure(PTP), mean air flow rate(MFR), etc. Subjective voice evaluation was surveyed through VHI and VOISS. To evaluate patients' symptoms related to functional voice disorder, scores on physical domain in VHI and VOISS were selected to be compared for each session. Results: The 10 out of 20 participants who complained of voice symptoms had no significant difference with pre-operation in acoustic evaluation, but all showed higher scores on 2 weeks and 3 months after operation compared to pre-operation, in VHI-physical domain and selected questionnaires in VOISS. They reduced MPT and increased PTP value simultaneously. Laryngeal massage and breathing training were simultaneously treated to them, 5 participants resulting in improvement in MPT and PTP compared to pre-treatment. Conclusion:Patients who complained voice change with no organic damage after thyroidectomy were all shown to have reduced MPT and increased PTP in some by aerodynamic evaluations. Reduced MPT may imply some problem in air flow beneath glottis. Increased PTP suggests much more effort in vocalization mechanism than pre-operation. Comparing aerodynamic evaluations in post-thyroidectomy may provide information on behavioral interventions. Additionally, study on laryngeal massage and breathing training simultaneously treated to patients with such voice disorder is needed to be conducted with larger number of participants.
