The purpose of this study is to investigate the evolution of regional tourism resources from the perspective of business ecosystem network. A regional tourism structure changes due to various factors such as natural resources, facilities, festivals and events, public resources, and etc. An exploratory analysis was conducted to examine the interaction between resource characteristics and alliance complexity in the regional tourism industry. In the process, the duality of technology provides an insight into the interaction among several players within an alliance network which include regional attractions and tourism industry. As a result. we identified four types of tourism alliance network: functional, organizational, resource-oriented, and artificially-allied. The managerial implications are also discussed.

Energy and Air Quality Benefits of DCV with Wireless Sensor Network in Underground Parking Lots

Cho, Hong-Jae,Jeong, Jae-Weon Council on Tall Building and Urban Habitat Korea 2014 International journal of high-rise buildings Vol.3 No.2

This study measured and compared the variation of ventilation rate and fan energy consumption according to various control strategies after installing wireless sensor-based pilot ventilation system in order to verify the applicability of demand-controlled ventilation (DCV) strategy that was efficient ventilation control strategy for underground parking lot. The underground parking lot pilot ventilation system controlled the ventilation rate by directly or indirectly tracking the traffic load in real-time after sensing data, using vehicle detection sensors and carbon monoxide (CO) and carbon dioxide ($CO_2$) sensor. The ventilation system has operated for 9 hours per a day. It responded real-time data every 10 minutes, providing ventilation rate in conformance with the input traffic load or contaminant level at that time. A ventilation rate of pilot ventilation system can be controlled at 8 levels. The reason is that a ventilation unit consists of 8 high-speed nozzle jet fans. This study proposed vehicle detection sensor based demand-controlled ventilation (VDS-DCV) strategy that would accurately trace direct traffic load and CO sensor based demand-controlled ventilation (CO-DCV) strategy that would indirectly estimate traffic load through the concentration of contaminants. In order to apply DCV strategy based on real-time traffic load, the minimum required ventilation rate per a single vehicle was applied. It was derived through the design ventilation rate and total parking capacity in the underground parking lot. This is because current ventilation standard established per unit floor area or unit volume of the space made it difficult to apply DCV strategy according to the real-time variation of traffic load. According to the results in this study, two DCV strategies in the underground parking lot are considered to be a good alternative approach that satisfies both energy saving and healthy indoor environment in comparison with the conventional control strategies.

Objective: This study evaluated the efficacy of the second line chemotherapeutic regimens in persistent or recurrent epithelial ovarian cancer (EOC) by analyzing the multicenter medical data retrospectively. Methods: We reviewed clinical data of 398 persistent or recurrent EOC/PPC patients treated with second-line chemotherapy between January 2006 and December 2016. And patients were divided into three groups, platinum resistant (less than 6 months), platinum-partially sensitive (6 to 12 month) and platinum sensitive group (over 12 months), based on the first recurrence time; also the second line chemotherapeutic regimen was identified in each group. Then the duration of recurrence after the completion of second-line chemotherapy was measured and the progression-free survival (PFS) according to the second line chemotherapeutic regimen was compared. Results: The study consisted of 222 eligible and assessable patients, median age 53 years, 69 (31.1%) were platinum-resistant, 66 (29.7%) were platinum-partial sensitive and 87 (39.2%) were platinum-sensitive group. There were no significant PFS differences between regimens in both platinum-resistant and platinum-sensitive group. In platinum-partially sensitive group, however, taxane containing regimen showed significantly longer PFS than other regimens (P < 0.05). In the 6-12 month group, Median PFS of taxane containing regimen was 25 weeks, S-phase inhibitor was 15 week, topoisomerase 1inhibitor was 16 weeks, and topoisomerase 2 inhibitor was 13 weeks, respectively. Conclusion: : PFS of taxane-containing regimen is better than other regimens in platinum-partially sensitive group. There were no significant PFS differences between regimens in both platinum-resistant and platinum-sensitive group.

Energy Saving Potentials of Ventilation Controls Based on Real-time Vehicle Detection in Underground Parking Facilities

Cho, Hong-Jae,Park, Joon-Young,Jeong, Jae-Weon Council on Tall Building and Urban Habitat Korea 2013 International journal of high-rise buildings Vol.2 No.4

The main topic of this paper is to show a possibility of indoor air quality enhancement and the fan energy savings in underground parking facilities by applying the demand-controlled ventilation (DCV) strategy based on the real-time variation of the traffic load. The established ventilation rate is estimated by considering the passing distance, CO emission rate, idling time of a vehicle, and the floor area of the parking facility. However, they are hard to be integrated into the real-time DCV control. As a solution to this problem, the minimum ventilation rate per a single vehicle is derived in this research based on the actual ventilation data acquired from several existing underground parking facilities. And then its applicability to the DCV based on the real-time variation of the traffic load is verified by simulating the real-time carbon monoxide concentration variation. The energy saving potentials of the proposed DCV strategy is also checked by comparing it with those for the current underground parking facility ventilation systems found in the open literature.

The main objective of this study was to verify a possibility of indoor air environment enhancement via actual operation of ionizer device. Two pollutants, benzene and toluene, were used as indicators for evaluating the air cleaning performance of ionizers. The test results show that negative air ions may provide the air cleaning effect which can be acquired by supplying 0.058-0.100(㎥/hr), 0.035-0.070(㎥/hr) ventilation. Another indicator of this test result, air cleaning factor(ACF) was also indicated that the impact of negative air ions is consistently maintained during the ionizer operation. In addition, according to experimental results, it was also found that removal efficiency of benzene was 2.1 times higher than that of toluene. From this research and existing literature, one can conclude that additional indoor air quality improvement can be expected by applying ionizers in ventilation system for underground parking facilities.

This study investigated the characteristics of natural organic matter (NOM) with general water characteristics (pH, DO, electrical conductivity, BOD, COD, TN, TP, Chl-a, DOC, UV254, SUVA) and the 3D fluorescence excitation-emission matrix (FEEM) in the Yeongsan River basin. FEEM was used to classify protein-like and fulvic & humiclike substances with fluorescence intensity in the matrix of excitation and emission wavelength. The concentration of BOD, COD, TN, electrical conductivity and DOC in the region of Gwangju city (Gwangju sewage treatment plant: GJS, Gwangjucheon: GJC, Gwangju 2: GJ2) was relatively higher than the upper reaches and lower reaches of the Yeongsan River basin. SUVA in most sites was lower than 3 L mg--1 m--1 as the hydrophilic substances, except Damyang (DY) in the upper reaches of Yeongsan river was higher than 3 L mg--1 m--1 as the hydrophobic substances during winter and autumn. In the FEEM investigation the fulvic and humic substances were found in most sites, and in sites regarding Gwangju city (GJS, GJC, GJ2) during winter and GJC in summer, protein-like substances were found. The trend of fluorescence intensities from the upper reaches to the lower reaches in most sites corresponded to that regarding the concentration of water characteristics (BOD, COD, TN, DOC). That is why the region of Gwangju city (GJS, GJC, GJ2) was relatively higher. This results were an equivalent trend to those of fluorescence index (FI) in most sites, and the higher FIs in the sites of Gwangju city indicate more microbial-derived substances due to enormous effluent organic matters (EfOM) from huge Gwangju sewage treatment plants.
