Assessment of noise exposed population is to check the environment noise level and social influence in order to reduce the risks such as annoyance and disturbance that are generated by environmental noise. Also, this method suggests the preferential noise abatement policy and action plan by accurately finding the area that the noise causes harmful effect to human health. Recently, a noise map, which can predict noise in comprehensive area, is used for the assessment of noise exposed population, breaking from the methods using existing measures. In particular, countermeasure for noise can be considered more effectively by using assessment methods of noise exposed population for specific noise level, area, and building types which are the main input factors in noise maps. In this study, we propose noise reduction ranking decision at ship construction and repair process due to noise map.

개발과 보전 간 갈등을 최소화할 수 있는 지속가능한 국토 관리를 위해서는 기본적으로 다양한 생물들의 서식처가 될 수 있는 자연환경 우수지역에 대한 관리가 이루어져야 한다. 자연환경 우수지역에 대한 효율적 관리를 위해서는 자연환경 우수지역 중에서도 법적·제도적으로 보호받지 못하고 개발에 노출된 지역들에 대해 지속적인 현황 파악의 노력이 필요하다. 본 연구에서는 국토환경성평가지도의 환경생태적 평가 결과와 법제적 평가 결과를 활용한 Gap 분석을 통하여 환경생태적으로 자연환경이 우수하나 제도적으로 보호받지 못하는 관리취약지역을 추출하는 방안을 제안하고자 하였다. Gap 분석 결과, 전국토의 4.81%와 국토환경성 평가지도 환경생태적 평가 1등급 지역의 11.22%가 자연환경적으로 우수하나 제도적으로 보호받지 못하는 관리취약지역으로 분석되 었다. 그리고 이러한 대표지역들의 현황을 살펴본 결과, 국토의 계획 및 이용에 관한 법률상 자연녹지지역으로 지정되어 있었으며, 기타법률에 의거 준보전산지, 가축사육제한구역 그리고 인근 학교로 인한 상대보호구역으로 지정된 지역들이었으며, 이러한 관리 취약지역들은 여건만 조성된다면 개발이 발생할 수 있는 지역들이었다. 따라서 이러한 지역들의 보호를 위해 제도적으로 보호할 수 있는 관리 방안을 고려해야 한다. 그리고 이러한 자연환경이 우수한 관리취약지역의 제도적 관리와 보호 대책 마련을 통해 국내 생물다양성을 증진시키고 지속가능한 국토관리가 가능할 것으로 판단된다.

대동여지도의 지도학적 특성에 대한 연구가 상당히 이루어졌음에도 불구하고 투영법에 대한 체계적이고 종합적인 연구는 드문 편이다. 이 연구의 주된 목적은 GIS 분석에 기초하여 대동여지도의 투영법을 추정하고, 그 특성을 파악하는 것이다. 이를 위해 먼저 대동여지도와 같은 고지도에 대한 투영법 추정의 절차와 GIS 기반의 분석 방법을 정립하였다. 핵심적인 과정은 각 후보 투영법을 적용한 준거 지도 상의 통제점을 고지도 상의 좌표로 기하변환한 후 고지도와의 위치 일치도와 형태 일치도를 분석하는 과정을 모든 후보 투영법에 반복적으로 수행하여 가장 적합도가 높은 투영법을 선정하는 것이다. 13종의 후보 투영법에 대해 다양한 투영 기준선을 적용하여 대동여지도의 투영법을 추정한 결과 정형원추도법 혹은 정형원통도법의 적합성이 가장 높은 것으로 나타났다. 하지만 오차의 분포가 이질적으로 존재하는데, 남부는 상당히 오차가 작은 반면 북쪽으로 갈수록 위치 오차와 형태 오차가 증가되었다. 따라서 남북 간에 적합한 투영법이 서로 다를 것으로 간주하고, 대동여지도의 북부와 남부에 대한 분석을 별도로 수행하였다. 그 결과 대동여지도의 북부는 정적원통도법이, 남부는 정거원추도법 및 정형원추도법의 적합도가 가장 높았으나, 남부의 경우 투영법 간에 적합도의 차이가 크지 않았다. 이 연구는 고지도에 대한 GIS 분석 연구의 확대에 기여한다는 의의가 있으나 향후 적합도를 측정하는 방법의 개선이나 통제점의 검증 등이 필요하다.

대한제국 칙령 제41호에 명시된 석도(石島) 명칭과 독도(獨島)와의 관련성을 밝히기 위한 연구는 상당한 진척이 있었음에도 불구하고, 일본측 연구자들은 여전히 칙령 속 석도 명칭이 독도라고 보기는 어렵다는 주장을 되풀이하고 있다. ‘석도=독도’에 대한 선행연구는 주로 순한국말과 한자 표기와의 관계를 분석함으로써 독섬(돌섬)이 석도나 독도와 같이 표기될 수 있음을 보여주고 있다. 그렇지만, 한국어 활용에 익숙하지 않은 외국인들이 한국어와 한자표기와의 관계를 이해하기에는 여전히 어려움이 있는 것으로 사료된다. 따라서 이 연구의 목적은 제3자의 눈에 비친 조선후기 독도 명칭의 용례를 밝히고, 이러한 사실이 오늘날의 독도영유권 논거에 주는 함의를 도출하는 것이다. 즉, 독일인 지도학자 시볼트의 ｢한국전도｣에 표기된 독도(Tok to) 명칭을 조선후기 고지도 및 현대 북한지도 속 석도 명칭과 비교함으로써 석도 명칭과 독도와의 상호 관련성을 좀 더 보편적이고 객관적인 측면에서 다루고자 하였다. 연구결과, 조선후기에 한국에서는 독도라 부르던 섬을 지도와 문서에는 석도로 표기했던 사실이 확인되었다. 연구결과는 칙령 속 석도 명칭이 독도를 지칭하였다는 역사적 사실을 더욱 확고하게 하는데 기여할 것으로 기대한다

This study was carried out to apply the UAV(Unmanned Aerial Vehicle) coupled with Multispectral sensor for the algae bloom monitoring in river. The study acquired remote sensing data using UAV on the midstream area of Gum River, one of four major rivers in South Korea. Normalized difference vegetation index (NDVI) is used for monitoring algae change. This study conducted water sampling and analysis in the field for correlating with NDVI values. Among the samples analyzed, the chlorophyll concentration exhibited strong and significant linear relationships with NDVI, and thus NDVI was chosen for algae bloom index to identify emergence aspect of phytoplankton in river. Aerial remote sensing technology can provide more accurate, flexible, cheaper, and faster monitoring methods of detecting and predicting eutrophication and therefore cyanobacteria bloom in water reservoirs compared to currently used technology. As a result, there was high level of correlation in chlorophyll-a and NDVI. It is expected that when this remote water quality and pollution monitoring technology is applied in the field, it would be able to improve capabilities to deal with the river water quality and pollution at the early stage.

Cryptography is a science to maintain the security of the message by changing data or information into a different form, so the message cannot be recognized. Today, many algorithms have been proposed for image encryption, but the chaotic encryption methods have a good combination of speed and high security. In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. The chaos-based encryption schemes are composed of two steps: chaotic confusion and pixel diffusion. In the chaotic confusion stage, a combination of the chaotic maps is used to realize the confusion of all pixels. In this paper, we first give a brief introduction into chaotic image encryption and then we investigate some important properties and behaviour of the logistic map. The logistic map, aperiodic trajectory, or random-like fluctuation, could not be obtained with some choice of initial condition. Therefore, a noisy logistic map with an additive system noise is introduced. The proposed scheme is based on the extended map of the Clifford strange attractor, where each dimension has a specific role in the encryption process. Two dimensions are used for pixel permutation and the third dimension is used for pixel diffusion. In order to optimize the Clifford encryption system we increase the space key by using the noisy logistic map and a novel encryption scheme based on the Clifford attractor and the noisy logistic map for secure transfer images is proposed. This algorithm consists of two parts: the noisy logistic map shuffle of the pixel position and the pixel value. We use times for shuffling the pixel position and value then we generate the new pixel position and value by the Clifford system. To illustrate the efficiency of the proposed scheme, various types of security analysis are tested. It can be concluded that the proposed image encryption system is a suitable choice for practical applications.

We present a comparative study of CO and polycyclic aromatic hydrocarbon (PAH) emission toward a region including the massive star-forming regions of NGC 6334 and NGC 6357. We use the NANTEN 12CO(J=1{0) data and the AKARI 9 m All-Sky diffuse map in order to evaluate the calibration accuracy of the AKARI data. We conrm that the overall CO distribution shows a good spatial correspondence with the PAH emission, and their intensities exhibit a good power-law correlation with a spatial resolution down to 4′ over the region of 10◦10◦. We also reveal poorer correlation for small scale structures between the two quantities toward NGC 6357, due to strong UV radiation from local sources. Larger scatter in the correlation toward NGC 6357 indicates higher ionization degree and/or PAH excitation than that of NGC 6334.

The scale of disaster and damage witnessed in the 2004 Indian Ocean Tsunami and the 2011 Great East Japan Tsunami has motivated researchers in developing foolproof disaster mitigation techniques for safety of coastal communities. This study focuses on developing tsunami hazard map by numerical modeling at Imwon Port to minimize losses of human beings and property damage when a real tsunami event occurs. A hazard map is developed based on inundation maps obtained by numerical modeling of 3 past and 11 virtual tsunami cases. The linear shallow-water equations with manipulation of frequency dispersion and the non-linear shallow-water equations are employed to obtain inundation maps. The inundation map gives the maximum extent of expected flooded area and corresponding inundation depths which helps in identifying vulnerable areas for unexpected tsunami attacks. The information can be used for planning and developing safety zones and evacuation structures to minimize damage in case of real tsunami events.

Chinese cabbage is produced and consumed as a main material for kimchi and as a staple vegetable in Korea throughout the year. However, due to environmental changes unbalance between supply and demand is repeated annually, requiring development of long-term storage technologies. Chinese cabbages, were harvested, put in plastic boxes, and precooled at 2oC for 24 hours using forced air precooler. After precooling, Chinese cabbages were MAP-treated with 0.02 mm HDPE film and functional film and stored at low temperature (1±0.5oC). The weight-loss rates after 9-weeks of storage were 8.47% in the control group, 4.07% in the HDPE film-treated group, and 3.07% in the functional film-treated group, respectively, suppressing weight loss. Trimming loss rate after 6-weeks of storage was 6.86% in the functional film MAP-treated group and lower than 7.50% in the control group. In the sensory test with 7 points as the limit of commodity, the control group lost it after 6-weeks of storage while the MAP-treated groups retained over 7 points. The functional film MAP-treated group showed over 6 points for processing as kimchi until 9-weeks of storage, proving that Pallet-type MAP storage is effective for extending storage life of spring Chinese cabbage.

환경과 개발이 조화된 한반도 국토 종합개발 계획 수립을 위해서는 환경계획에 활용할 수 있는 환경공간정보가 필요하다. 하지만 기 구축되어 있는 북한지역의 환경공간정보는 매우 한정적이다. 기존 환경부의 대분류 토지피복지도가 있으나, 대분류 토지피복지도는 국토의 토지피복분류를 7개 항목으로만 분류체계가 구분되어 있고, 공간 해상도 또한 떨어져 정책적으로 활용할 수 있는 분야가 제한적이다. 따라서 본 연구에서는 접근불능지역을 대상으로 원격탐사 기술을 적용하여 신규 구축이 가능한 토지피복지도가 북한 지역의 환경공간정보로 타당하 다고 판단하였다. 그리고 기존 대분류 토지피복지도보다 공간 및 속성 해상도가 높아 다양한 분야에서 활용할 수 있는 중분류 토지피복지도를 구축하고자 하였다. 이를 위해 환경, 도시, 산림, 농업 분야의 토지피복지도 관련 구축 현황을 살펴보았으며, 각각의 분야에서 이용하고 있는 분류체계를 기반으로 중분류 토지피복지도의 구축 가능성과 활용성을 고려하여, 기존 환경부 중분류 토지피복지도의 22개 분류체계에서 신규 16개 분류체계로 변경하여 각각의 분류체계의 구축방안을 제시하였다. 그리고 개성지역을 시범지역으로 선정하고, 각각의 분류체계별 구축방안을 시범 구축하였다. 이러한 북한지역의 토지피복지도의 시범구축 결과 분류체계의 항목별 전체 분류정확도는 95.35%로 산정되어, 북한지역의 중분류 토지피복지도 구축에 적용가능하다 판단하였다.

이 연구는 러시아의 극동진출과 제국주의 팽창과정에서 만들어진 측량과 그 성과물인 지도에 대해 분석하고, 해안선을 중심으로 이루어진 실제 측량성과에 따라 한반도에 관한 지리정보가 신속히 유럽에 알려지게 되었음을 논증한다. 북경조약과 블라디보스토크항의 건립시기인 1860년을 중심으로 시작된 러시아의 군사용 지도 제작은, 1884년 조러 수호 통상 조약을 통해 조직적으로 이루어지면서 1902~3년 19매의 축척 1:420,000지도를 작성하기에 이르렀다. 하지만 1905년 러 ․일 전쟁 패배 이후로 한반도를 대상으로 하는 지도제작은 중지된다. 당시까지 가장 대축척인 이들 지도들은 유럽에 전파되어 한반도에 대한 가장 상세한 지리정보를 전달하는 역할을 한 것으로 판단된다.

Introduction The term “coping”refers to the actions or thoughts that people use to deal with stressful encounters (Folkman, Lazarus, Gruen, & DeLongis, 1986). Coping strategies are adopted to change the stressed person-environment relationship by either confronting and/or by regulating the emotions (Lazarus & Folkman, 1987). Research focusing on coping mechanisms has been a prolific area of study, emerged from a wide range of disciplines including psychology, sociology, and anthropology. However, for marketing researchers, questions still remain about the issue of how coping strategies are manifested in everyday consumption contexts. This represents an important area of research in that consumer coping behavior can determine critical post-purchase outcomes such as re-patronage intention, repurchase intention, and word of mouth (Raghunathan & Pham, 1999). When a service failure occurs, consumers frequently experience negative emotions and make decisions under emotionally taxing conditions (Yi & Baumgartner, 2004). Numerous scholars have made attempts to understand various consumption-related emotions and subsequent conditions corresponding to them (e.g., Raghunathan & Pham, 1999; Richins, 1997; Sujan et al., 1999). However, despite the large volume of studies focusing on consumer emotions, very few studies have examined the relationships between negative emotions with consumer coping strategies (Yi & Baumgartner, 2004). With that in mind, the primary aim of this conceptual paper was to propose a model that delineates consumer coping mechanisms derived from negatives emotions in a service failure and recovery context. Conceptual Model Coping strategies are closely linked with an individual’s attempt to manage a given stressful environment (Lazarus, 1991). Lazarus and Folkman (1984) defined coping as “constantly changing cognitive and behavioral efforts to manage specific external and/or internal demands that are appraised as taxing or exceeding the resources of the person”(p. 141). Menaghan (1983, p. 159) defined coping efforts as “specific actions (covert or overt) taken in specific situations that are intended to reduce a given problem or stress.”Duhachek (2005) defined coping construct as “the set of cognitive and behavioral processes initiated by consumers in response to emotionally arousing, stress inducing interactions with the environment aimed at bringing forth more desirable emotional states and reduced levels of stress.”Thus, the key aspects of coping includes a consequence of emotion, a dynamic process, and behavior and emotional domains of consumer responses (Duhachek, 2005). Implicit in this conceptualization is the idea that links the emotions aroused from a particular circumstance, coping strategies, and subsequent behaviors. As shown in Figure 1, our conceptual model classifies a wide range of negative emotions generated by a service failure that are linked to a set of consumer coping strategies. This will in turn influence subsequent consumer post-purchase behaviors. The behaviors will be either retaliatory (vindictive WOM, brand switching, complaining) or conciliatory (positive WOM, re-patronage intention, repurchase intention) responses. Related Literature When an individual encounters a stressful event, different negative emotions are triggered according to one’s distinct appraisals of the situation (Lazarus, 1991). These appraisals, in turn, affect how the consumer responds to the situation emotionally and behaviorally. These emotions remain powerful until the emotion eliciting problems are resolved. Proposition 1. Cognitive appraisal of the service failure situation evokes negative emotions. While some studies use combined negative emotions to explain resultant consumer behavior, others suggest separate emotion inventories (Lerner & Keltner, 2001) as different emotions trigger huge variation in cognition. Consumer negative emotions that are associated with a service failure condition can be categorized into several subsets (Watson & Clark, 1992). Many studies have utilized a limited number of negative emotions to explain consumer behavior in a service failure context (Nguyen & McColl-Kennedy, 2003). Bonifield and Cole (2006) used an appraisal-tendency framework to predict the underlying mechanism of anger and regret, associated with consumers’appraisals about service failure and their effects on post-purchase behaviors. Yi and Baumgartner (2004) focused on four negative emotions of anger, disappointment, regret, and worry in a purchase context to investigate their linkages to consumer coping strategies. Further, Tronvoll (2011) identified a set of negative emotions experienced in unfavorable service experiences leading to consumer complaint such as shame, sadness, fear, anger, and frustration. Although some marketing theorists consider the emotion of frustration to be an overlap with anger, they can be distinct emotions, especially in the context of service failure, because blaming someone else is different from blaming no particular others (Roseman, 1991). Therefore, the subsequent behavior and adapting coping strategy may differ. Thus, this study distinguished frustration separated from anger. Building on the aforementioned research, this study identified five different categories of negative emotions that are frequently found in a purchase-related situation: anger, frustration, disappointment, regret, and anxiety. Anger associates with feeling of attacking someone or yelling, resulting from an individual to be blamed on of the situation (Lazarus, 1991). Frustration tends to occur when people attribute a goal incongruent event to situational factors (Roseman, 1991). Disappointment refers to the feeling occurred due to the outcome insufficient to meet the expectation (Ortony et al., 1988). Regret is evoked when alternative option seems to be better than the selected one (Zeelenberg et al., 1994). Anxiety is linked to uncontrollable circumstances that are not directly under the purview of the provider or the customer (Ruth, Brunel, & Otnes, 2002). Proposition 1-1. Consumer negative emotions associated with a service failure situation are categorized into anger, frustration, disappointment, regret, and anxiety. Appraisal theorists contend that people use different coping strategies to reduce negative emotions accordingly (Lazarus 1991). In this study, consumer coping strategies were categorized into engagement (problem-focused, emotion-focused) and disengagement categories. Coping strategies in the engagement category involves individuals actively trying to manage, control, or change both problem- and emotion-focused aspects of the stressful person and/or environment transaction (Tobin et al., 1989). Problem-focused coping occurs when an individual tries to manage the source of the stress. Emotion-focused coping refers to where the individual changes the meaning of the event or regulates the expressing emotions (Lazarus & Folkman, 1984). In the disengagement category, mental disengagement strategy involves doing other things to take one’s mind off the problem, denial (refusing to believe that something has happened), distancing (refusing to think about the problem), and escape/avoidance (wishing problem would go away or somehow be over with). On the other hand, behavioral disengagement strategy involves consumers deciding to give up further action as nothing can be done about the situation. They acknowledge that a goal cannot be reached and that further efforts are futile. As the mechanism behind each type of coping strategy differs, the negative emotions generated from varying conditions are linked accordingly. Since anger arises from appraisals of other-responsibility, angry consumers often manifest in confrontive coping, aggressive action towards the blameworthy organization (Smith & Bolton, 2002). With respect to frustration, one is more likely to foster support-seeking coping as this does not imply blame attribution to a particular person or organization (Roseman, 1991), Further, previous work has suggested that person-related disappointment tends to result in confrontive coping behaviors such as direct complaining (Zeelenberg & Pieters, 2004) and behavioral disengagement (Yi & Baumgartner, 2004). On ther other hand, complaining about it or telling others is unlikely take place for regret as this may highlight he or she mistake (Zeelenberg & Pieters, 2004). Lastly, anxiety tends to be associated with escape behaviors (Roseman, Antoniou, & Jose, 1996). Thus, anxiety consumers often are linked with emotion-focused coping such as mental disengagement. In addition, more proactive, problem-focused coping is likely to take place as stated in some other studies (Yi & Baumgatner, 2004). Proposition 2. Negative emotions have differential impacts on consumer coping strategies. Service failure literature indicates that negative emotions influence diverse retaliatory responses. Romani Grappi and Dalli (2012) contended that negative emotions of anger, discontent, dislike, embarrassment, sadness, and worry are associated with behaviors such as switching, complaining, and negative word of mouth. Maute & Dubé(1999) also indicated that customer anger is liked to exit and negative WOM. Likewise, Blodgett et al. (1999) similarly suggested that consumers are prone to spread negative word of mouth when they perceive service failure. However, even if a particular coping strategy is activated, depending on the strategy applied, the subsequent behavior can be changed. Many researchers indicated that when a service failure is not recovered, it is more likely to lead to negative WOM and complaining behavior (Anderson, 1998). Especially, WOM behavior is more emotion-driven responses (Sundaram, Mitra, and Webster, 1998). Therefore, vindictive WOM behavior is more likely to occur when the emotions are not handled properly. In addition, Kau and Loh (2006) stated that dissatisfied customers who do not directly complain to the firm about their negative experiences may not only engage in vindictive word of mouth behavior, but also switch to another brand. Sabharwal, Soch and Kaur (2010) also suggested that dissatisfied non complaints are likely to exit the service provider more easily resulting in brand switching. Bonifield and Cole (2007) identified conciliatory behaviors to include positive WOM, willingness to return to a service provider, and feeling sympathy for the service provider. Blodgett et al. (1993) suggested that when service failure is recovered, positive word of mouth will take place. Voight (2007) revealed that when certain platform is provided for customers to express their feeling regarding their purchase, customer loyalty increases. Proposition 3. Coping strategies lead to either retaliatory responses or conciliatory responses. Proposition 3-1. Disengaging coping strategies are associated with vindictive WOM, brand switching, complaining behavior more than engaging coping strategies. Proposition 3-2. Engaging coping strategies are associated with positive WOM, re-patronage intention, re-purchase intention. Additionally, our model proposes two individual characteristics as moderators: self-efficacy and self-band connection. Especially, those with high self-brand connection are assumed to counter-argue negative brand information in a service failure situation as this concept captures a strong “self”relevant emotive tie between the brand and the consumer (Escalas, 2004). We contend that these consumers would use prior brand knowledge to neglect their negative emotions and make more brand favoring attributions following service failure. Therefore, depending on the the previous connection with the brand performing the service failure, corresponding coping strategy may change. As self-efficacy relates to the belief that an adequate coping response is available, both factors should relate to the strategies consumers use to cope (Sujan et al., 1999). Proposition 4. Individual characteristics such as self-efficacy and self-brand connection moderates the relationships between negative emotions and coping strategies. Conclusions This paper integrates a broad range of literature into a conceptual framework that delineates consumer coping strategies in a service failure and recovery context. In so doing, the model establishes clear categories for classifying negative emotions consumers experience in a service failure situation into testable elements, and it is argued that although the concept of coping is not a simple one, it should be central to any examination of the service failure and recovery phenomenon. Also, the proposed model considers where marketers’recovery efforts should be directed by describing the ways in which consumers cope with a service failure. How a firm responds to its customers when a service failure occurs can say more about that firm than any other customer interaction. If handled well, it can cultivate emotionally intense relational outcomes. However, if the firm handles the situation badly, it may cause highly negative reactions with customers taking their feedback to online reviews and social media conversations in a way that can seriously damage the firm’s reputation. Future research is needed to empirically test and extend the proposed model. Further empirical research in a particular service setting would advance marketing research as well as be of great managerial significance.
