Despite a surging amount of research on value co-creation in the social media context, research on how value co-creation and value co-destruction coexist from a system perspective remains scarce. This conceptual research aims to understand how social media allows for value to be co-created and/or co-destroyed in interconnected social networks. The study takes a first step toward integrating the two value processes in the social media context and opens up new research possibilities. By looking at value co-creation, we differentiate between values that are created from both firm and customer sides and show the value can be destructed if without cautions. From a managerial standpoint, the proposed framework could facilitate managers to build a more holistic view of creating social media value through collaboration with their social media users.

Architectural Monuments have to overcome the challenge of time due to physical properties. The fundamental issue must be grounded in an understanding of history and art to overcome this challenge and make them sustainable. Many efforts to preserve the monuments through the 19th century and at the beginning of the 20th century to record them in scientific form were successful. To be aware of the meaning of the art and not to be ‘barbare’ anymore was behind the promotion of these activities. Above all, the 19th-century French architect Viollet-le-Duc contrasted the concept of barbarism with the concept of art and tried to redefine architecture as art. The ritual to escape ‘barbare’ played an important role in the end. This consciousness was also at work in the propaganda for the preservation of medieval architectural monuments in France, led by intellectuals such as Rodin. Also, the concept of ‘barbare’ served as an important yardstick whenever the cause of their loss was questioned while important monuments were destroyed in the First World War. From the viewpoint of Germany, Dehio was the pioneer of the preservation movement and documentation of monuments. The principle he advocated was preservation, not restoration. The historian Pevsner, who moved to England, also surveyed monuments in various parts of England and left them in the same format as Dehio. These facts show that architecture as art plays a fundamental role in the history of human life.

Plasma Arc Melter (MSO) system has been developed for the treatment and the stabilization of various kinds of hazardous and radioactive waste into the readily disposable solidification products. Molten salt oxidation system has been developed for the for the treatment of halogen- and sulfurbearing hazardous and radioactive waste without emissions of PCDD/Fs and acid gases. However, PAM system has showed some difficulty in the off-gas treatment system due to the volatilization of radionuclides and toxic metals at extremely high-temperature plasma arc melter and the emissions of acid gases. MSO system has also showed the difficulty in the treatment of spent molten salt into the disposable waste form. Present study discussed the results of organics destruction performance tests for the PAM-MSO combination system, which is proposed and developed to compensate the drawbacks of each system. The worst-case condition tests for the organics destruction were conducted at lowest temperatures and the worst-case condition tests for the retention of metals and radionuclides were conducted at highested temperatures under the range of normal operating condition. For the worst-case organic destruction test, C6H5Cl was selected as a POHCs (Principal Organic Hazardous Constituents) because of its high incinerability ranking and the property of generation of chlorine gases and PCDD/Fs when incompletely destroyed. Simulated concrete waste spiked with 1 L of C6H5Cl was treated and the emissions of 17 kinds of PCDD/Fs and other hazardous gases such as CO, THCs, NOx, SO2 and HCl/Cl2 were measured. For the worst-case condition tests for the retention of metals and radionuclides, Pb and Cs were selected because of its high volatility characteristics. The emissions of PCDD/Fs was extremely lowered than the emission limit and those of other hazardous constituents were below their emission limit. The results of performance tests on the organics destruction suggested that tested PAM-MSO combination system could readily treat PCBs-bearing spent insulation liquid, spent ion-exchange resins used for the treatment of spent decontamination liquid in the decommission process and the concreted debris bearing hazardous organic coating materials. The decontamination factor of Cs and Co were 1.4×105, 1.4×105, respectively. The emisison of Pb was 0.562 ppm. These results suggested that tested PAM-MSO system treated low-level radioactive and pb-bearing mixed waste.

2000년대 이후, 우리나라에서는 공립미술관이 대거 개관하면서 그 중요성을 새롭게 재인 식하는 시대를 맞이하였다. 이와 함께 공립작가미술관도 계속 증가해가며 그 입지를 더욱 강화해 가는 모습을 보여주고 있다. 요제프 슘페터는 새로운 것들의 끊임없는 결합과 적용을 통해 기존 의 것들을 혁신해나가는 ‘창조적 파괴’의 개념을 고안해냈다. 따라서 이 연구는 ‘이응노의집’에 초점을 맞춰 우리나라 공립작가미술관의 현황을 점검해보고, 창조적 파괴의 개념을 통해 이응노 의 예술세계를 기념하는 이응노의집의 미래경영 방안을 제언해 보고자 한다. 특히 이 연구는 근 대미술관이 부재한 한국의 미술관 현황을 고려하여 이응노의 예술세계를 핵으로 하는 근대미술 관으로 자리매김하는 이응노의집의 미래경영 전략과 방안을 구상해 보여주고자 한다.

PURPOSES : The exposed aggregate number (EAN) and mean texture depth (MTD) of exposed aggregate concrete pavement (EACP) influence the functional performance of EACP in terms of pavement noise and skid resistance. The selection of the exposure time of EACP is important because the designed EAN and MTD of EACP can be achieved when the exposure process is performed at an appropriate time. On the one hand, too early exposure may cause protrusions and unwanted removal of aggregates and mortar. On the other hand, late exposure may cause difficulty in exposure of the mortar. In this study, a method to determine the optimum exposure time for EACP is suggested using a non-destructive method. METHODS : A set of laboratory tests was performed to investigate the variation in EAN and MTD of EACP according to the elastic modulus obtained by non-destructive equipment. From the results of this investigation, the optimum exposure time using the non-destructive method and the exposure time window (ETW) method was suggested. In addition, the usefulness of ETW suggested by laboratory tests was verified from a field application. RESULTS : From the laboratory tests, it was found that the targets of the surface condition of EACP (EAN: 59 per 25 cm2, MTD: 1.39 mm) can be achieved when the concrete elastic modulus is higher than 20GPa. The proposed guideline using the non-destructive method was applied for the field construction of EACP and achieved similar results. CONCLUSIONS : It was found that the proposed guideline for determining the exposure time window based on non-destructive testing is useful.

이 연구의 목적은 전승4국에 의해 각각 4분할된 전범국 독일의 동서독 분단과 베를린 분할, 소련과 동독 당국에 의한 베를린 장벽의 구축, 그리 고 동독 주민들의 여행 자유 개방에 따른 베를린 장벽 해체 등을 통해 동 서독의 통일을 고찰하는 데 있다. 연구방법으로는 전승4국과 양독2국 간 쟁점이 되어 온 베를린 장벽의 구축과 해체에 관하여 헤겔의 정(正, These)→반(反, Antithese)→합(合, Synthese) 변증법을 적용하였다. ⓛ 전승4국이 전전(戰前) 회담의 산물인 전범국 독일을 동서독 분단과 동서 베를린 분할을 해 놓은 국제질서하에서 패권을 장악하려는 의미에서의 정 (正), ② 그중에서 소련과 동독 당국이 기존 국제질서를 깨고 공산주의 패 권을 유지하고자 베를린 장벽을 구축한 의미에서의 반(反), 그리고 ③ 베 를린 장벽 해체가 의도되지는 않았지만 동독 주민들의 이주와 이탈을 넘 어서 동유럽의 민주화 일환으로 나타난 촛불시위, 동독 SED 대변인 샤보 브스키(G. Schabowski)의 기자회견에서의 ‘즉시, 지체 없이’ 국경개방 허 용 발언의 말실수 등이 ‘부정의 부정’으로 지양(止揚, Aufheben)되면서 베 를린 장벽이 해체되는 수순을 밟게 되는 의미에서의 합(合)인 것이다. 요 컨대 미국과 소련 중심의 전승4국은 전범국 독일을 분할하여 패권이란 국 제질서를 지속하고자 했으나, 오히려 소련과 동독이 베를린 장벽 구축에 나서면서 그들만의 공산권 체제유지를 강화하고자 했다. 그러나 동서독 여 행 자유와 국경개방 시위에 나선 동독 주민들의 자유화와 동독 당국의 개 방에 대한 모호한 태도 등이 중첩되면서 베를린 장벽이 해체되기에 이르 렀다. 따라서 베를린 장벽의 해체는 독일 통일을 앞당기는 단초가 되었고, 정상적인 통일 독일로 자리매김한 것은 더이상 분단 독일이 지속될 수 없 다는 변증법적 논리를 깨우쳐준 사실이 아닌가 한다.

『수호전』의 양산박은 ‘헤테로토피아(Heterotopia)’적 공간으로서, 현실세계에 존재 하지만 다른 현실공간과는 절대적으로 다른 공간인 대항 공간으로 존재하고 있으며, 이것은 ‘이의제기의 공간’으로 생성되었으며 ‘한시적 공간’으로 소멸되었다고 볼 수 있다. 양산박의 생성과 소멸은 ‘헤테로토피아’의 원리를 보여주고 있다. 수호전에 함축된 다양한 의미를 파악하기 위해서는 다양한 시각을 통한 접근이 필요할 것으로 보인다. 작품에서 추구하는 이상세계가 어떠한 ‘공간’을 이루고 있으며 이 ‘공간’이 현실세계에 어떻게 구성되는지를 통해 그 장소가 지니는 함의를 분석해보는 것은 작 품의 본질을 파악하는 하나의 시각이 될 수 있을 것으로 보인다.

From a marketer’s perspective, place is only a sacrosanct component of the marketing mix (McCarthy, 1960), and extends into services’ “7Ps” (Grӧnroos, 1994). The servicescape literature explores how stimuli present within commercial consumption settings or servicescapes impact consumer behaviors (Rosenbaum & Massiah, 2011). Arguably, marketers view place as exchange locales, and they do not understand the evocative role that they assume in consumers’ lives (Sherry, 2000). Within cultural geography, places represent “profound centres of human existence” (Relph, 1976, p. 43). Place is a triad comprising of a physical setting, activities, and meanings (see Relph, 1976). This paper investigates how Israeli Jews attribute meanings to places associated with their destruction during the Holocaust (1939 – 1945). Respondents were eight Jewish Israelis who recently participated in the educational Holocuast sojourn (i.e, Warsaw Ghetto, Treblinka, and Aushwitz). Using long interviews, the authors put forth a framework that shows how the participants assign place-based meanings on four dimensions. The individual dimension reflects how the tour personally impacts visitors’ lives. The communal dimension, explores the trip impact’s the individual’s view towards Israel and Israeli nationalism (Zionism). The religiosity dimension reflects tour’s impact on a participant’s self-identity as a Jew (e.g., secular, conservative, Orthodox). Lastly, the global dimension explores the trip’s impact on a participant’s identity as a human being in a global world. Did the trip alter a participant’s views towards mankind, towards genocide, and universal lessons that everyone may learn from the Holocaust? Results help to understand the evocative role that places often assume in consumers’ lives. Place no longer seem as inert; instead, spaces imbued with meanings impact lives, experiences, and even one’s overall well-being. From a broader perspective, the results suggest a different role that consumption settings may assume in consumers’ lives. Places may impact consumers on multiple levels, and the essence of understanding the profound bonds that consumers often form with places, originates not from the functions that places serve, but rather, from the meanings that consumers often assign to place.

In recent years, there was many conflagration about special structure such as wooden cultural assets, warehouses and factories. The common causes of increase in the fire damage were difficulty of the initial suppression and absence of equipment for appropriate disaster prevention. A prediction of the air injection diameter of the destruction-spray nozzle, a core technology of destruction-spray fire vehicle which is possible for fire suppression of special structure were studied. As a result, changes in water flow according to the air injection diameter is not large, but air flow rate showed a difference more than up to four times. And then, through the result data of the flow analysis, the air injection diameter was obtained in the target mix ratio of the air according to the water injection pressure. Finally, by the formula derivation for the air injection diameter of target mix ratio of the air, the air injection diameter according to the water injection pressure change could be predicted within an error of 10%.

In recent years, there was many conflagration about special structure such as wooden cultural assets, warehouses and factories. The common causes of increase in the fire damage were difficulty of the initial suppression and absence of equipment for appropriate disaster prevention. In this study, the destruction-spray nozzles, a core technology of destruction-spray fire vehicle which is possible for fire suppression of special structure was studied using the finite element method. As a result, the maximum deviation of the part nozzle was 18.1% compared with the reference value. Second, the maximum deviation of the nozzle module was 13.5% compared with the part nozzle. Third, the safety factor about internal pressure of the nozzle module was suitable as 13.6. Finally, the performance of the designed destruction-spray nozzle was satisfied with 4,652.1L/min in excess of the target performance.

Recently, there are a lot of fires breaking out at special structures. To suppress this fire break down at early stage is very important because it leads to bigger damage in case of special structures. For early suppression, outer wall of building has to be destroyed and need waterproofing for Ignition temperature. So far there is no equipment developed local and all of them are imported from a broad. In this study, In this study, The CAE analysis was the Leading-in of the boom conditions for the development of demolition fire according to the environment of Korea. As a result of this, could be confirmed that decreases stress reduction. maximum 51% to 12% depending on the part. It was possible structural integrity and design. about Telescopic Boom and Outrigger on the basis of this result.

허베이호 기름유출사건은 우리나라 최악의 해양오염사건으로 기록될 정도로 국민들에게 큰 충격을 안겨주었을 뿐만 아니라 해양생태계의 파괴와 더불어 천문학적인 경제적 손실을 발생시켰다. 이 사고로 정부는 사고 인근지역을 특별재난지역으로 선포하게 되었고, 유류오염사고에 대한 신속한 피해배상과 지원을 통한 피해주민의 생계안정과 지역경제 회생을 위해 ´허베이 스피리트호 유류오염사고 피해주민의 지원 및 해양환경의 복원 등에 관한 특별법´까지 제정하게 되었다. 그렇지만 제1심과 제2심의 판결과는 달리 대법원은 허베이호 규모와 사고 당시 파공의 크기를 산술적으로 계산하여, 허베이호 규모에 비하여 손상이 미미하므로 형법 제187조에서 정한 선박의 파괴에 이를 정도가 아니라고 판시하였다. 따라서 이 논문에서는 형법 제187조의 보호법익을 검토한 뒤, ‘파괴’에 관한 판례와 학설의 입장을 비판적으로 고찰하고서, 파괴에 관한 새로운 개념정립을 시도하고 있다. 이어서 원심 및 대상판례를 비판적으로 검토한 뒤, ‘파괴’에 관한 새로운 개념에 근거하여 대상판례를 비판하고 있다.

A strain of Bacillus thuringiensis, named Bt 1-3, was isolated from Korean soil sample and it showed high insecticidal activity against Plutella xylostella. Bt 1-3 was deterimined to belong to ssp. aizawai (H7) by an H antiserum agglutination test and produced bipyramidal-shaped crystal proteins. PCR analysis with specific cry gene primers showed that Bt 1-3 contained cry1Aa, cry1Ab, cry1C, cry1D and cry2Ab genes. In addition, this isolate showed high uptake rate of foreign plasmid by electroporation. Based on these characteristics of Bt 1-3, we tried to construct a spore-free Bt 1-3 mutant by knock-out sigG gene, which is known as a key transcription factor during sporulation. First, we constructed a basal vector, named pDST, consisting of erythromycin resistant gene (EmR), partial polyhedrin gene and temperature sensitive origin of replication gene (Orits). Subsequently, according to the chromosomal DNA sequence of Bt subsp. konkukian 97-27, we amplifed upstream and downstream regions of Bt 1-3 sigG, and cloned into pDST (pDST-G). So far, several EmR colonies were obtained by electroporating into the wildtype Bt 1-3 and crossover by homologous recombination is going on.
