Generation X and baby boomers represent a significant group that are willing to spend. According to the American Express Open Forum (2013), baby boomers in America between the age 49 and 65 are more in favor of spending than any other consumer group. The Hyundai Research Institute (2015) stated that the market size for baby boomers will increase over 18% annually in Korea. Equally important is generation X, because this group is also reaching a high-earning stage of their lives (Luxury Daily, 2011). Further, they are predicted to take the place of baby boomers as a cash cow for marketers (American Express Open Forum, 2014).This lucrative demographic of baby boomers and generation X is a potential gold mine. Despite the fact that these groups are showing such interest in spending, brands and retailers are not giving them the same amount of attention. While more middle-aged women want to dress more youthfully, retailers and brands are not evolving their products at the same pace (USA Today, 2008). They are finding it difficult to find a solution to meet the needs of this aging but youthful group (USA Today, 2008). Brands such as Chico’s and Ann Taylor are not providing the styles that the women want, so boomers turn to younger brands such as Abercrombie & Fitch, H&M, and Forever 21 (Forbes, 2008). But the younger brands are not satiating their needs, either (Forbes, 2008). While the boomers and generation X are harnessing fashion economic control, the players in the market are lagging behind. To understand what the market must do to meet the apparel needs of baby boomers and generation X, it is pivotal to delve into how they feel about their age and how it affects the factors that influence their purchasing. According to Schiffman and Sherman (1991), aging is more of a state of mind than a physical state. Understanding older consumers through cognitive age (self-perceived age) has been done by many researchers (Sudbury & Simcock, 2009; Szmigin & Carrigan, 2012). Cognitive age indicates how older people view themselves in the context of aging. Barak and Schiffman (1981) stated that elderly respondents identified themselves as a younger age group when they were asked about their age-related feelings and actions. Equally important is understanding how cognitive age affects the physical self, which in this study, is body cathexis. Body cathexis, according to Labat and DeLong (1990), is “the evaluative dimension of body image and is defined as a positive and negative feeling towards one’s body.” While women may feel younger than they actually are, the body is inevitably aging. As Jang and Yoo (2011) reported after studying Korean women in their 40s and 50s, the correlation between cognitive ages and ideal body images were significant, and the younger they feel, the younger body images they desired. In addition, the physical self highly influences a person’s choice of clothing and how they perceive clothing in general (Kwon & Parham, 1994). When clothing is used in a positive manner, it can boost one’s self-confidence (Alexander, Connell, & Presly, 2005). It is also thought to be an extension of the physical self (Horn & Gurel, 1981). By understanding what middle-aged women seek when buying clothes, we can assume how satisfied they are about their body. Thus, the clothing benefits items and purchasing behavior of middle-aged women would most likely reflect the function of their clothing and how they perceive themselves.

ANALYSIS OF SNS ACTIVITY AS LEISURE CONSUMPTION - FOCUSED ON THE SNS MARKET ACTIVITY OF WOMEN CONSUMERS OF THE TWENTIES TO THIRTIES

Heejin Park,Sunguk Choi,Heeju Chae 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

As the usage of smartphones increased rapidly due to the popularization of smart phones, it appears that the average daily usage time of Korean people was 3 hours and 39 minutes, and it was analyzed that the twenties uses 4 hours 41 minutes longer than the average (Jung, 2015). It, also, was found that users mainly use smartphones for receiving information retrieval, social network sites (SNS) activities, listening to music, watching games, and watching videos. In consequence, various contents suitable for smartphones are increasing rapidly. In particular, the number of users who are engaged in SNS activities through smartphones is rapidly increasing and its influence is gradually getting bigger. (Park & Lee, 2012). SNS activities provide content that gives entertainment in a short time and at the same time make consumption regardless of time and space like in subways or cafes, and also stimulate users through visual elements. The content that can be enjoyed in 10 to 15 minutes like snacks, which are easily eaten regardless of time and space, is called 'snack culture'. (Ko, 2015) According to Cheil Worldwide, 2000 media outlets for men and women aged between 13 and 59 living in major cities across the country, the phenomenon of easily consuming short videos, web cartoons, and web novels appeared noticeably. As a result of investigating the main purposes of smartphones, the use of relatively short contents such as SNS has increased (Bae, 2015). SNS provides users with simple contents similar to snacks, and users tend to use SNS as a leisure activity by using these services in 'leisure time' which is the time of their spare time. In this way, as the number of SNS steadily increased, SNS activity has also naturally increased. Consequently, as the SNS market has rocketed among various activities, the e-commerce using it is become popular. This type of consumption activity is called leisure spending (Cho & Do, 2010). Thus, it is necessary to analyze whether consumers view SNS activities as part of their leisure life. Although there are a lot of active consumption activities happening in consequence of using SNS after the spread of smartphones, there is very little research done on the relationship between SNS activity and the leisure life. This study, therefore, intends to conduct in-depth interviews on twenty women in their twenties and thirties who are actively engaged in consumption activities in the SNS market, on the issue of whether they acknowledge SNS activities and consumption behavior in the SNS market as recreational activities. The purposes of this study are as follows: first, to find out the meaning to SNS activities as a leisure activity to female consumers of the twenties and the thirties; second, to explore the approaching process and motivation of leisure life extending to leisure spending; third, to examine the relation between experience of commitment and leisure satisfaction through previous research and in-depth interview In addition, this study is the cornerstone of research on SNS market which is becoming an issue as one new consumption trend and which recognizes consumption activity that happens in the market as leisure consumption in reference to leisure. It is considered to be utilized variously when establishing marketing strategy of fashion companies, which will use image consumption based SNS later.

The Impact of the SEC`s 2003 Mutual Fund Voting Disclosure Rule

( Heejin Park ) 한국재무관리학회 2015 財務管理硏究 Vol.32 No.2

I explore whether the SEC`s 2003 mutual fund voting disclosure rule has an impact on voting behaviors of mutual funds by comparing the association between mutual fund ownership and aggregate voting outcomes before and after the rules are adopted. By using management sponsored proposals and shareholder sponsored proposals in proxy seasons 2001 and 2006, I find no evidence that mutual funds` voting support for management declined after the disclosure rule, as projected by advocates of the rule based on increased transparency. Rather the level of mutual funds` voting support for management increase after the adoption of the rule.

Efficient machine learning over encrypted data with non-interactive communication

Park, Heejin,Kim, Pyung,Kim, Heeyoul,Park, Ki-Woong,Lee, Younho Elsevier 2018 Computer standards & interfaces Vol.58 No.-

<P><B>Abstract</B></P> <P>In this paper, we describe a protocol framework that can perform classification tasks in a privacy-preserving manner. To demonstrate the feasibility of the proposed framework, we implement two protocols supporting Naive Bayes classification. We overcome the heavy computational load of conventional fully homomorphic encryption-based privacy-preserving protocols by using various optimization techniques. The proposed method differs from previous techniques insofar as it requires no intermediate interactions between the server and the client while executing the protocol, except for the mandatory interaction to obtain the decryption result of the encrypted classification output. As a result of this minimal interaction, the proposed method is relatively stable. Furthermore, the decryption key is used only once during the execution of the protocol, overcoming a potential security issue caused by the frequent exposure of the decryption key in memory. The proposed implementation uses a cryptographic primitive that is secure against attacks with quantum computers. Therefore, the framework described in this paper is expected to be robust against future quantum computer attacks.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A privacy-preserving machine learning protocol framework is proposed. </LI> <LI> The proposed protocol preserves the privacy of model, user input, and classification output. </LI> <LI> We realized the Naive–Bayesian classification protocol on our framework. </LI> <LI> We utilized Fully Homomorphic Encryption only for implementation. </LI> <LI> The proposed supports higher security and communication efficiency. </LI> </UL> </P>

Mutual Fund Voting and Pension Ties : Evidence from Proxy Voting

Heejin Park 한국파생상품학회 2017 선물연구 Vol.25 No.2

본 연구는 뮤추얼펀드가 연금자산을 확보할 목적으로 주주의 이익을 최대화하기 위한 방향이 아닌 연금자산을 맡긴 기업에 유리하게끔 proxy voting에서 투표권을 행사하는지를 알아보는 연구이다. 다시 말해 뮤추얼펀드가 기업의 수탁자(trustee)로 선정되어서 pension business tie가 있는 경우, 해당 뮤추얼펀드가 기탁자 기업의 경영진에 유리하도록 투표권을 행사하는지를 알아보고자 한다. 실증분석을 통해서 뮤추얼펀드 패밀리 단계에서는, pension business tie와 뮤추얼펀드가 경영진이 제안한 안건에 대한 지지율이 양의 관계가 있음을 발견했다. 또한 개별 뮤추얼 펀드 단계에서는, 개별 뮤추얼펀드는 그들의 포트폴리오에 속한 기업의 퇴직연금의 투자옵션 중에 하나로 포함될 경우 더욱더 경영진에 유리하게 투표권을 행사한다는 증명했다. 이 연구는 최근 AFL-CIO에서 제안했듯이 SEC가 뮤추얼펀드는 그들이 투자하는 기업과의 business tie를 공시해야 한다는 주장에 대한 시사점을 제시한다. Because mutual funds are the largest equity holders and because the retirement assets that are managed by mutual funds have been growing, mutual fund managers may have more incentives to support management in order to attract and retain pension business. I explore whether pension business ties have an impact on voting behaviors of mutual funds by examining the link pension business ties between mutual funds and the firms to actual mutual fund voting outcomes. At the fund family level, I find a positive relation between pension ties and mutual funds` voting support for management. This relation becomes stronger when there is a voting divergence among funds within the same families. At the individual fund level, I find that individual funds are more likely to vote with management if they are included as one of the investment options of the pension plan of their portfolio firms. This suggests that the SEC should at least consider the recent petition from the AFL-CIO proposing that the SEC require mutual funds to disclose business ties with the firms in which they invest.

CASE REPORT : Response to Neoadjuvant Chemoradiotherapy in a Patient with Mucinous Adenocarcinoma Arising from a Chronic Anorectal Fistula and Diagnosed by Transrectal Punch Biopsy: A Case Report

( Heejin Park ),( Dahyun Jung ),( Sunoch Yoon ),( Chanhee Kyung ),( Ikjae Lee ),( Joohee Kim ),( Hyojin Park ) 대한장연구학회 2013 Intestinal Research Vol.11 No.4

Mucinous adenocarcinoma arising from a chronic anorectal fistula is a rare condition. It is often confused with a hemorrhoid or perineal abscess, which consequently delays accurate diagnosis. Here, we report the case of a 58-year-old man with blood-tinged stool who reported a rectal mass, which was diagnosed as mucinous adenocarcinoma arising from an anal fistula. After initial computed tomography-guided needle aspiration biopsy had failed to provide an accurate diagnosis, transrectal punch biopsy was performed to obtained adequate tissue sample for confirmative histological diagnosis. The patient was successfully treated with neoadjuvant concurrent chemoradiotherapy followed by surgical intervention. (Intest Res 2013;11:306-309)

Optimal Safety Color of Working Garment for Forestry Industry

HeeJin Kim,Kyungmin Lee,DaEun Park,YungKyung Park 한국색채학회 2017 AIC 2017 Jeju Vol.2017 No.10

The function of safety clothes is to increase discrimination and visibility of the worker in order to prevent accidents at the workplace. It was shown that “laid-in” and “collision” items are located at the top in accidents of domestic forestry operation. The most visible fabrics the indoor environments were bright orange and red. The highest rank of temporal discrimination was found in samples with the highest saturation. Three types of patterns-bold, stripe, and cross-based on ISO was tested for visibility under indoor and outdoor conditions. We recommend a color saturation of about 80 or more, which affects the discrimination, and a color saturation of at least 50, which affects visibility. It is also recommended that the surface area is wide or spread in the same area at both near and far distance.
