Objective : Electrodiagnostic test has shown diagnostic sensitivity and specificity in carpal tunnel syndrome[CTS]. This study was to evaluate the correlation between clinical outcome of endoscopic carpal tunnel ligament release[ECTR] and the predictive value of sensory nerve conduction. Methods : From January 1998 to December 2004, 87 patients [44 right hand, 37 left hand, 6 bilateral hands] with CTS who underwent ECTR were followed up in our hospital for an average of 24 months. We retrospectively analyzed the results with previous medical records. All patients underwent electrodiagnostic test and ECTR. The patients were divided into three groups according to the electrodiagnostic test results. Group [A] was normal sensory nerve response, Group [B] was slowing sensory response and Group [C] was no sensory response. Improvement of the symptom after ECTR was assessed using a visual analogue scale[VAS] score. Results : Differences between the three groups on the correlation of severity of sensory potential and duration of preoperative symptoms were significant. The mean value of improved VAS scores for the three groups were $6.0{\pm}0.96$ in the Group A, $6.11{\pm}0.48$ in the Group B and $6.14{\pm}0.53$ in the Group C. There was no statistically significant difference between the severity of sensory nerve response and improvement in VAS score after ECTR. Complications included a wound infection, a case of skin necrosis, and two patients with persistent symptoms without any improvement. Conclusion : Although electrodiagnostic test has been known to be useful, sensory nerve response is considered not to be a good prognostic value for carpal tunnel syndrome after ECTR.

The article concerns the cultural diversity as a policy value for the cultural industry policy in Korea. in the evolution of the cultural industry policy since the end of the 1990s, the primary values of the public policy has focused on the establishment of the cultural identity and the improvement of the competitiveness of the cultural industries. It Is likely that cultural diversify has been considered as a defensive value against the cultural globalization. Meanwhile, as the UNESCO indicates, the improvement of the cultural diversify should be established as a key policy value in terms of the cultural rights, cultural welfare and social inclusion. In this respect, the article analyzes the policy values of the cultural industry policy in terms of the cultural diversity. In addition, the policy alternatives for the improvement of the cultural diversity will be recommended. In particular, the article studies the case on the comic industry policy.

In this study, it propose what the landscape elements is to be improved urgently and how to improve landscape by reflecting the rural village characteristics away from the spatial integrated landscape planning. The study area for landscape research is selected as the 9 rural villages in Chungcheongbuk-do, and research is done by using village unit landscape diagnostic index(VULDI). the result is shown that average VULDI value of the rural village zones is bigger than one of the town village zones with difference of 15%. Two zones of Chilseong-myeon and Sangchon-myeon among the town village zones are appeared to be similar with the rural village zones in landscape level by VULDI value. Generally, the rural villages to maintain the good landscape have the low population and high engagement rate in agriculture. Looking political support criteria at the landscape level, the seven zones except Deoksan-myeon and Maengdong-myeon have high VULDI value more than 60%, which means that it seems unnecessary to support political landscape improvement. However, when it is divided into two parts of the village inside landscape and the surrounding landscape, 8 rural village zones except one zone of Sangchon-myeon have low VULDI value less than 60%, which means it is necessary to support political landscape improvement. It is important to give the intensive support of ever urgent landscape improvements and high priority landscape elements on the results of the diagnostic before planning of the rural landscape formation.

This paper suggests the design and operation of value stream mapping(VSM) applied to project management, such as R&D, IT Investment. First this study represents design methodology of VSM process using SIPOC(Supplier, Input, Process, Output, Costumer). Second, this paper considers the identification and improvement plan about non-added value time for VSM using FPC(Flow Process Chart) and PERT/CPM. Last, this paper proposes VSM scheduling method using PERT/CPM and CCPM(Critical Chain Project Management)

Purpose - This study estimated the non-market value of pumped storage power generation using the contingent valuation method(CVM). Design/methodology/approach - CVM, a non-market value estimation method, was used. The perception of pumped storage power generation and the willingness to pay(WTP) for pumped storage power generation were investigated among 612 randomly selected households. Findings - It was analyzed that the average value per household was 7309.99 won/month, and the sources of these benefits were 1819.37 won due to the improvement of power generation efficiency, 1320.48 won due to the improvement of power system reliability, 2359.24 won due to the stabilization of electricity rates, 2110.89 won due to water resource management It was assumed that a circle occurred. If the average monthly benefit per household is expanded to cover countries across the country, it is estimated that the annual value to our society from pumped storage power generation will be KRW 1.796.6 trillion. Research implications or Originality - It is necessary to consider the operation of pumped-water power generation by reflecting the value of pumped-up power generation that is not evaluated in the market. Since Korea's electricity market is isolated in a state where it is impossible to connect with other countries, it may be vulnerable to a stable electricity operation system. Therefore, there is a need for a facility that can stably secure reserve power and produce power quickly when necessary. If pumped-water power generation is actively used for power operation, a more stable power system can be secured.

Background and Objectives: The purpose of this study was to evaluate the efficacy of revision cochlear implant (CI) surgery for better speech comprehension targeting patients with low satisfaction after first CI surgery. Subjects and Methods: Eight patients who could not upgrade speech processors because of an too early CI model and who wanted to change the whole system were included. After revision CI surgery, we compared speech comprehension before and after revision CI surgery. Categoies of Auditory Performance (CAP) score, vowel and consonant confusion test, Ling 6 sounds, word and sentence identification test were done. Results: The interval between surgeries ranged from eight years to 19 years. Same manufacturer's latest product was used for revision surgery in six cases of eight cases. Full insertion of electrode was possible in most of cases (seven of eight). CAP score (p-value=0.01), vowel confusion test (p-value=0.041), one syllable word identification test (p-value=0.026), two syllable identification test (p-value=0.028), sentence identification test (p-value=0.028) had significant improvement. Consonant confusion test (p-value=0.063), Ling 6 sound test (p-value=0.066) had improvement but it is not significant. Conclusions: Although there are some limitations of our study design, we could identify the effect of revision (upgrade) CI surgery indirectly. So we concluded that if patient complain low functional gain or low satisfaction after first CI surgery, revision (device upgrade) CI surgery is meaningful even if there is no device failure.

Objectives : This study aims to investigate the acute oral toxicity and safety of Samsoeum (Shensuyin) extracts and fermented Samsoeum extracts. Methods : For that objective, we used ICR mice. ICR mice were administerd orally with dosage of 1250mg/kg, 2500mg/kg and 5000mg/kg of Samsoeum extracts and fermented Samsoeum extracts. Results : We daily examined number of deaths, clinical signs, body weights and gross findings for 2 weeks. 1. The results of acute oral toxicity using ICR mice showed that LD50 of value over 5000 mg/kg. 2. Samsoeum extracts and fermented Samsoeum extracts not affect on bodyweight gross findings of ICR mice. 3. The results of Serum chemistry analysis and Complete Blood Count(CBC) through the autopsy were showed normal range values. Conclusions : Samsoeum extracts and fermented Samsoeum extracts did not show any toxic effects in ICR mice. And oral LD50 value was over 5000mg/kg in ICR mice and it is very safe for ICR mice.
