Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.

Background: Though skin metastasis is rare, it can seriously affect the prognosis and management. The role of dermoscopy in primary skin cancers are established well, but its role in skin metastasis hasn’t been clear. Objectives: This study was performed to elucidate the dermoscopic patterns of metastatic skin cancers. Methods: We analyzed the dermoscopic patterns and clinical data of 46 patients with metastatic skin cancers at Pusan National University Hospitals (Busan and Yangsan) from 2005 to 2018. Results: Mean age and disease free interval were 62.0±14.2 years and 29.2±41.2 months, respectively. The most common primary origin of cancer was breast (11/46, 23.9%), followed by lung (8/46, 17.4%), and upper gastrointestinal tract (8/46, 17.4%). Any dermoscopic patterns was not found in 8 cases, who showed subcutaneous nodules without surface change. Most common dermoscopic pattern was vascular pattern (30/46, 65.2%), followed by homogenous structureless pattern (16/46, 34.8%). Most common vascular pattern was serpentine and arborizing vessel (23/46, 50%), followed by dotted vessel (7/46, 15.2%). There was no significant difference in dermoscopic vascular pattern among cancers, because the number of subjects was insufficient. Conclusion: Based on our study, when vascular patterns such as serpentine and arborizing vessel or dotted vessel are seen on dermoscopy within a nodule in a patient already diagnosed with cancer, metastatic skin cancer should be strongly considered.

Background: Despite characteristic clinical features of glomus tumor, dermatologists can meet diagnostic difficulty in some cases with glomus tumor. Objectives: To investigate clinical features and dermoscopic findings of glomus tumors. Methods: For 22 cases of glomus tumors, sex, age of initial visit, disease duration, site of lesion, size, associated symptoms and nail deformities and dermoscopic findings were investigated. Results: Mean age of initial visit and disease duration was 43.4±13.4 years old and 5.6±5.1 years, respectively(19 female, 3 male). Both 1st Fingers(9, 40.9%) were most common involved site. Nail lunula(12,54.5%) was more frequently involved than proximal nail fold(6,27.3%) or nail bed(4,18.2%). 15 cases were identifiable for size, and mean size was 6.0±1.9mm. There was associated symptoms such as pain(16,72.7%), tenderness(7,31.8%) and cold intolerance(2,9.1%). Onychoschizia(13,59.1%), longitudinal ridging(12,54.5%) and distal nail notching(8,36.4%) were commonly associated nail changes. On dermoscopic examination, whitish patch(16, 72.7%), purplish patch(15, 68.2%), erythematous patch(13, 59.1%) and irregular linear vessel(1, 4.5%) were observed. In 9 cases(40.9%), characteristic three zone consisting of central purplish patch, middle erythematous patch and peripheral whitish patch were observed. Conclusion: Characteristic dermoscopic findings of this study can help making more accurate diagnosis and performing appropriated treatment in glomus tumors

Hydatidiform mole with a coexisting fetus is rare, but this condition has recently shown an increased incidence because of assisted reproduction technology. In most of the reported cases, termination at diagnosis was preferred due to poor fetal survival and maternal risk factors such as vaginal bleeding, preeclampsia, hyperthyroidism, potential of malignant change. However, considering the value of pregnancy by assisted reproduction technology, whether to continue or to terminate this condition is a dilemma. Based on currently available information, it seems that it is reasonable to allow the pregnancy to continue in the absence of maternal complications. We report on a case of the complete hydatidiform mole with two coexisting fetuses with a brief reviews of the literature.

“글로벌화 對 현지화”에 관한 오랜 논쟁을 새로운 관점으로 조명

Hwy-Chang Moon,Lorna Geddis,Jin-Uk Kim 한국조직경영개발학회 2009 조직경영개발연구 Vol.2 No.1

국제시장으로 진출하는데 있어 글로벌화할 것인가 아니면 현지화할 것인가에 관한 논쟁은 매우 오랫동안 지속되어 왔다. 본 논문은 이러한 흑백논리의 논쟁을 끝마치고 문제의 핵심을 동태적인 관점에서 새롭게 해결하였다. 심층적 문헌연구를 통하여 국제화의 다양한 형태인 다국내적, 글로벌, 그리고 초국적 등의 기업을 “통합-적응(I-R) 모델”을 활용하여 이 논쟁을 분석했다. 다음으로 이러한 기업들이 어떻게 동태적으로 변하는 가를 보여주기 위해서 “동태적 다변화 조정(DDC) 모델”을 사용하여 더욱 정교하게 설명하였다. 구체적으로 가치사슬을 상류부문과 하류부문으로 나누어 생산추구형과 시장추구형으로 구분하여 경영환경에 따라 전략적 선택을 달리하면서 다음 단계로 발전하는 과정을 사례를 통해서 보여 줌으로써 새로운 이론적 관점 뿐 아니라 현실적 시사점도 제공하였다. The debate between globalization and localization has been a lengthy and drawn out affair This paper aims to end the debate as it exists - a debate of black or white, right or wrong - and move it into an entirely new arena where dynamism is the name of the game A rigorous literature review provides readers with a fundamental understanding of typologies of firms such as multidomestic, global and transnational, and how they relate to the thems of standardization and differentiation, by analyzing them from an integration-responsiveness framework perspective This is followed by the introduction of a new firm concept the dynamically globalizing firm, which is representative of the dynamic nature of the firm and its ability to move from domestic to transnational The Dynamism of firms is schematically represented by introduction to the dynamic diversification-coordination (DDC) model, which allows firms to divide their value chain into possible paths to becoming a transnational firm - market-seeking or production-seeking

An Extension of Porter and Kramer's Creating Shared Value (CSV) : Reorienting Strategies and Seeking International Cooperation

Hwy-Chang Moon,Jimmyn Parc,So Hyun Yim,Nari Park 서울대학교 국제학연구소 2011 Journal of International and Area Studies Vol.18 No.2

This paper improves the theory of creating shared value (CSV), a new way to achieve economic success, which was introduced by Porter and Kramer. First, this study provides four types of corporations (Stupid Corporation, Selfish Corporation, Good Corporation, and Smart Corporation) categorized in terms of corporate and social benefits, and shows that the final destination for corporations is to be smart, meaning the ethics and strategy as the firm's basic measures to bolster value creation. Second, this paper provides four distinctive strategies in order to effectively create shared value, an extended version of three strategies presented by Porter and Kramer: defining core competence; reconceiving comprehensive targets; redefining productivity in the value chain; and enabling local or global cluster development. "Defining core competence" is newly added and "reconceiving comprehensive targets" is extended from Porter and Kramer's notion of "reconceiving products and markets." Above all, this paper highlights the importance of internationalization of CSV, unlike Porter and Kramer's emphasis on domestic clusters. The paper demonstrates the usefulness of these improvements in explaining CSV activities in the real world.

Cooperation among Japan, Korea, and China through Sharing Business and Cultural Advantages

Hwy-Chang Moon 韓國經營史學會 2014 經營史學 Vol.72 No.-

Today, regional integration is becoming a new form of economic cooperation around the world. Facing this trend, there is an intense pressure for the three Northeast Asian countries - Japan, Korea, and China to form a regional integration. This paper argues that culture is a crucial factor for successful cooperation among countries in a regional integration. For this purpose this paper has conducted empirical studies, using the OUI model of cultural dimensions. First, statistical methods have been applied to see the relationship between national competitiveness and cultural variables in general for 68 countries. Then the new framework has been applied to the three Northeast Asian countries in order to evaluate competitiveness. From the results of the empirical studies, this paper suggests important implications for cooperation among the three countries.

Location Advantages of Korea for the Telecommunication Industry : The Generalized Double Diamond Approach

Moon, Hwy-Chang,Kim, Seon-Sik 韓國國際經營學會 1999 國際經營硏究 Vol.10 No.1

The importance of the telecommunication industry is well recognized. However, few studies provide a systematic approach to measuring the competitiveness of this industry. In this paper, competitiveness and globalization indices are developed within the framework of the generalized double diamond model. These measures are calculated from the survey data of the evaluation of Korea's telecommunication industry by foreign investors in Korea. Policy makers will find these two indices useful in formulating effective policies to enhance the competitiveness of the telecommunication industry.

DYNAMIC GLOBALIZATION IN INTERNATIONAL BUSINESS

MOON,HWY-CHANG GRADUATE INSTITUTE FOR INTERNATIONAL AND AREA STUD 1999 Journal of International and Area Studies Vol.6 No.2

As globalization has been accelerating in recent years, there have been debates on whether business people must follow global standards or not. This paper discusses some related models and proposes a new perspective on global standards. Unlike other studies, this paper views global standards in a dynamic rather that static way. One important implication of this study is that global firms add values to the product and thereby global consumers rather than just to exploit global market. This paper also suggests that global managers should be careful not to overemphasize the local characteristics of product if they want to make the product truly competitive in the global market.
