In recent years, theme parks and events have become the most favorite modes of the mass tourism and leisure. This article analyses the difference from the satisfaction of event programs' attributes between visitors at two theme parks in Korea. The data were collected from 286 visitors visiting Korea's two representative theme parks regarded to lead the future industry in Korea. The empirical analysis showed that Everland theme park had four more satisfied attributes: 'uniqueness of event program', 'educational achievement', ' smooth progress', and 'safety on the event zone', and Lotteworld theme park had five ones: 'interesting', 'diversity', 'contents appropriate to the event purpose', 'the events everyone can enjoy', 'information'. The findings provide the information on the strength and the weakness of the two theme parks. Although this study has some limitations, future studies should be conducted in this field.

Purpose: The purpose of this study is to find out the correlation factors for prognosis of calcaneal fractures. Materials and Methods: 120 cases (feet) of calcaneal fractures, all of them followed up for more than 1 year after surgical procedures, consisted of 101 men (105 feet) and 13 women (15 feet) were reviewed retrospectively. The collected clinical data were as follows : injury mechanism, surgical procedures, time to procedure, time to work and the radiologic data: Bohler angle, heel width, displacement of posterior facet. AOFAS hindfoot score and VAS score were checked. With ANOVA test and multiple regression analysis, the data processed statistically. Results: According Sanders classification, type II was 37 cases (31%), type III 66 cases (55%), and type IV 17 cases (14%). On plane radiography, the Bohler angle improved to average 28.4 degree from 5.6 degree, and the displacement of posterior facet was corrected to average 1.2 mm. AOFAS hindfoot score was checked average 81.7 points postoperatively, and the meaningful difference existed between types of Sanders classification. The Bohler angle represented the outline of the calcaneus had the better correlation with the clinical outcome of calcaneal fractures rather than the anatomical reduction of the posterior facet did. And the width of calcaneus had good correlation with the clinical score. Conclusion: We should also concern about the outline of calcaneus, the width of calcaneus and the Bohler angle representing anatomical reduction, not only the acute reduction of the posterior facet.

박현우,Park, Hyun-Woo 대한족부족관절학회 2011 대한족부족관절학회지 Vol.15 No.2

전족부 통증의 주요 원인 중의 하나인 모턴씨 신경종, 즉 족지간 신경염은 진정한 종양이 아니라 신경 포착 증후군의 일종으로 이해되고 있으며, 진단 시 정확한 이학적 검사와 함께 전족부 통증의 원인이 되는 다른 질환과도 감별해야 한다. 치료에 있어서는 적절한 보존적 치료에도 증상 호전이 되지 않는 환자에게 수술적 치료로서 신경절제술이 주로 시행되어 약 80%의 환자가 만족하는 좋은 결과를 보고하고 있으나, 수술 후 만족스럽지 않은 결과를 보이는 2~35%의 환자를 적절히 처치함으로써 족지간 신경염의 치료 결과를 좀 더 만족스럽게 할 수 있을 것이다. Morton's neuroma is a common cause of forefoot pain, and is also known to be a entrapment neuropathy rather than a true tumor. Precise physical examination is necessary to differentiate from other diagnoses of similar symptoms. If proper conservative treatment modalities fail for this neuritis, neurectomy of interdigital nerve is generally performed, with the results of up to 80% of patient's satisfaction. However the failure rate of 2% to 35% should be improved by proper diagnosis and careful surgery.

Purpose: We analyzed to find out prognostic factors in the conservative treatment for the plantar fasciitis. Materials and Methods: The data were collected from 145 patients, 159 feet (M:F = 51:108) with conservative treatment and analyzed for possible prognostic factors : sex, age of onset, the duration of symptom before treatment, pain score before treatment, the duration for symptom remission, medication period, calcaneal pitch angle, and presence of calcaneal spur. Results: The duration of symptom before conservative treatment is affected to the prognosis, and the borderline of the effective period was about 6 months. Conclusion: With the conservative treatment of the plantar fasciitis, we found that (1) the duration of symptom before the conservative treatment was a prognostic factor, and (2) if the period before the conservative treatment was more than 6 months, the other treatment option such as surgery should be considered for this chronic group.

램파의 분산성과 파 반사가 시간반전과정에 미치는 영향의 이해

박현우,김승범,손훈,Park, Hyun-Woo,Kim, Sung-Bum,Sohn, Hoon 한국전산구조공학회 2009 한국전산구조공학회논문집 Vol.22 No.1

이 연구에서는 얇은 판형구조물의 손상탐지에 널리 사용되어오는 램파에 시간반전(time reversal)개념의 적용성을 이론적으로 규명한다. 고전적 시간반전 음향학에 의하면, 센서에서의 출력신호를 시간영역에서 반전 후 재입사시켜 원래의 가진점으로 돌려보내면, 그 가진점에서 원래 입력신호가 복원된다. 그러나 램파에 시간반전과정을 적용하게 되면 램파 고유의 분산성과 판 경계에서의 파 반사로 인해 시간반전성이 복잡한 양상을 띠게 된다. 이러한 램파의 시간반전성을 보다 잘 이해하기 위해 이 연구에서는 램파의 시간반전과정을 이론적으로 규명한다. 특히, 램파의 내부모드분산, 다중모드분산, 그리고 판 경계면에서의 램파의 반사가 시간반전성에 미치는 영향을 정식화하였다 간단한 수치예제를 통해 이 연구에서 제시된 이론적 발견들의 타당성을 검증한다. This study investigates the applicability of the time reversal concept in modem acoustics to the Lamb waves, which have been widely studied for defect detection in plate-like structures. According to conventional time reversal acoustics, an input signal can be reconstructed at an excitation point if an output signal recorded at another point is reversed in the time domain and emitted back to the original source point. However, the application of a time reversal process(TRP) to Lamb wave propagations is complicated due to velocity and amplitude dispersion characteristics of Lamb waves and reflections from the boundaries of a structure. In this study, theoretical investigations are presented to better understand the time reversibility of Lamb waves. In particular, the effects of within-mode dispersion, multimode dispersion, amplitude dispersion, and reflections from boundaries on the TRP are theoretically formulated. Simple numerical case studies are conducted to validate the theoretical findings of this study.

직사각형 판에서 가상탐지자 모델을 이용한 시간반전램파의 공간모임 규명

박현우,Park, Hyun-Woo 한국전산구조공학회 2011 한국전산구조공학회논문집 Vol.24 No.5

최근 3년간 판 구조물 건전성 감시분야에서 시간반전램파(Time reversal Lamb waves)의 가능성이 주목받고 있다. 이 연구에서는 직사각형 평판에서 시간반전램파의 공간모임을 적은 연산비용으로 효과적으로 모사할 수 있는 수치기법을 제안한다. 제안된 기법에서는 파 반사에 의해 발생하는 실제 탐지자의 거울상 효과와 등가를 이루는 활성 가상탐지자를 이용하여 시간반전과정을 주파수 영역에서 정식화한다. 시간반전램파의 공간모임 모사에서 필요한 순방향 및 역방향 파 전달은 스칼라 형태의 함수로 표현한다. 제안된 방법을 웨이퍼 형태의 압전소자가 병치된 직사각형 평판에서 시간반전램파의 공간 모임 문제에 적용하고 유한요소해석 결과와 비교하여 타당성을 검증한다. During the last three years, the possibility of the time reversal Lamb waves has been paid attention to for structural health monitoring of a plate. This study proposes a numerical scheme which can simulate the spatial focusing of time reversal Lamb waves on a rectangular plate. In this scheme, a time reversal process is formulated in the frequency domain using active virtual sensors being equivalent to the mirror effects of an actual sensor due to wave reflection on the plate boundary. Forward and backward Lamb wave propagations are represented by scalar functions for simulating the spatial focusing of time reversal Lamb waves. The validity of the proposed scheme is demonstrated through the comparison to the results of finite element analysis in which the spatial focusing of time reversal Lamb waves is realized by wafer-type piezoelectric(PZT) transducers collocated on a rectangular plate.

한국인터넷교환노드 성과분석에 관한 연구

박현우,Park, Hyun-Woo 한국전자통신학회 2008 한국전자통신학회 논문지 Vol.3 No.4

본 연구에서는 KIX의 성과분석을 위해, 민간기업과 정부기관 구분하여 분석하였다. 민간기업의 적용되는 BSC 성과분석 4개 관점간의 논리적 연계성(Logical Linkage)이 모든 기업에는 동일하게 적용가능하나, 정부기관에서는 4개의 관점간 논리적 연계성 확보가 곤란하다. 이러한 논리적 연계성 상실은 정부기관의 KIX 사업에 BSC 적용의 제약요인으로 작용한다. 이러한 내부와 외부 고찰 관점과 연계하여 KIX의 BSC 관점은 품질(운영)관점, 이용자(고객) 만족도 관점, 경제적 비용효과(재무)관점으로만 구분해 KIX의 BSC 성과분석의 내외부적 관점에 관한 연계모형과 BSC의 내외부적 관점을 근간으로 KIX의 성과분석 모형을 만들어 KIX 전체 사업에 대한 성과결과를 분석하였다. In this study, the performance analysis was divided into the public sector and private business sector. The four perspectives of the BSC performance analysis for the private business sector can be applied to all of the enterprises as there are Logical Linkages between the four Perspectives. However, these can not be applied in the same way to the public sector. There is no Logical Linkage between public sector and private sectors. Therefore, since there is no Logical Linkage, the KIX project of the public sector has a constrained condition. With the internal and external perspective views, the BSC of the KIX identifies the quality(operation) factor, user(customer) satisfaction factor, and economic costs effects(finance) factor. Based on the linkage model in both the internal and external perspective views and the BSC performance analysis of these views, a performance analysis model was developed and then performance results were analyzed of the whole KIX project.
