This is the third part of the four-part paper describing the development of a packet-switched computer communication network named the KORNET. In this paper we describe the design and implementation of the X.25 protocol connecting packet mode data terminal equipments(PDTE's) with data circuit terminating equipments(DCE's). In the KORNET, the X.25 protocol has been implemented on the line processing module-A(LPMA) of the network node processor(NNP). In the implementation of X.25, we have divided the software module according to the service function, and have determined the the rules that interact between the modules. Each layer protocol has been developed using the technique of the finite state machine. Before the actual coding of softwares, we hafve used formal software development tools based on the specification and description language (SDL) and program design languate (PDL) recommended by the CCITT. In addition, for the efficient operation of the X.25 protocol system we have analyzed the system performance and the service scheduling method of each module. The results will also be given.

'Hansik', or Korean cuisine is one of Korea national brands. To understand the domestic consumer awareness of Korean cuisine, data was gathered under the keyword search, 'Hansik.' Textom 3.5 was used to gather data from blogs, news media found on Naver from November 1, 2018, to October 31, 2019. The results from frequency and TF-IDF analysis indicate that the 'buffet' had the largest proportion in terms of consumer awareness to Hansik. Also, broadcasting contents starring star chefs had a great influence. The Hansik awareness did not remain in the domains of its traditionality, but also branched into extents into areas such as fusional and gourmet cuisine. UCINET6 and NetDraw were used to conduct CONCOR analysis. Four cluster formations have been found; various food cultural cluster, high-end restaurant cluster referring to aired restaurants on media, Hansik brand cluster, and Hansik buffet cluster. This study proposes presenting a various menu of Hansik which use a multiple number of ingredients. Also, a promotion that introduces fine Hansik and a development of marketing views and media contents about the convenient HMRs make the associated imagery of Hansik to be strengthen.

This study was carried out for the establishment of theory and foundational data for breeding, on variegated foliage plants using for potted plants, based on examination and analysis for shape, color, and area ratio of variegated leaves and chlorophyll contents. Six families, 18 genus, and 54 species of variegated plants domestically distributed in Korea were used as the plant materials. Patterns based on chlorophyll-deficient part in variegated leaves were divided into 20 types, such as steps, border, collapsed border, sandy border, half, silk, stars, vein, firewood, border and firewood, center, entirety, leaf, irregular, net, watermelon, melon, and so on. There were 10 kinds of colors including dark green, red, dark red, reddish white, reddish yellow, white, silver, silvery white, yellowish white, and yellow. The ratio of variegated area was ranged from 5.8% to 100% and it was diverse depending on species or cultivar. The ratios by patterns were highest in entirety (98.6%) and relatively high in step (60.8%), whereas, low in boarder, star and firewood (33.6-36.4%), and relatively low in half and vein (43%). Chlorophyll content of variegated leaf was rather lower compared to normal plants and chlorophyll b tended to be higher in ratio of chlorophyll a to b. Particularly content of chlorophyll b in Stromanthe sanguinea 'Triostar', Dracaena fragrans 'Massangeana Compacta', D. reflexa 'Song of India', and Tradescantia spathacea was higher than chlorophyll a in comparison with that of normal plants.

The concept of Corporate Social Responsibility (CSR) was first introduced sixty years ago in the academic field. However, the phrase CSR was not explicitly stated before the 1990s in Korean business and academic researches. Recently CSR is more considered a corporate strategy than a philanthropic donation. CSR comprises contributions to local communities as well as using environmentally beneficial and humane practices. Sponsoring is one available marketing tactic used in order to communicate with the market. This study of sponsorship has concentrated on developing brand asset by accessing potential values of sporting events or star-players. However, sponsorship includes providing funds or goods to non-profit institutions as well as sports or entertainment organizations. Accordingly corporate community-specific sponsorship is defined as firms offering to provide money, goods and/or services to individuals and/or institutions within a particular community, thus establishing an interdependent relationship between the partners aspiring to gain social and economic assets. National sponsorship is typically targeted toward commonly recognized individuals and/or organizations with the intent to maximize exposure of a sponsor's brand, and is known to positively affect brand equity(community-specific sponsorship is committed to a limited local area) that a firm could benefit from by gaining a specific asset. POSCO sponsors the Jukdo Market, locate dinthe city of Pohang, tohelp revive their traditional market. Inreturn, the Jukdo Market merchant suni on display sflags with the POSCO embleminfrontof stores with in the market intending to make shopper sand merchant saware of POSCO's sponsorship. POSCO has succeeded in acquiring public support from the citizens of Pohang. However, the economic effects resulting from the cooperative relationship between POSCO and the Jukdo Market have yet to be measured by any empirical research. The purpose of this study is to assess the economic effects created by the community-specific sponsorship from the groups of merchants and shoppers, measuring its influence on the corporate image and subsequent brand loyalty, as parts of brand equity. The result of the study shows that the community-specific sponsorship of POSCO of the Jukdo Market had different influences on its corporate image and the brand loyalty of shoppers and merchants. First, the merchant group who was more frequently exposed to POSCO's flag recognized the sponsorship of POSCO more than the shopper group, and, therefore, had a better image of the company. Second, the recognition of POSCO's sponsorship had a positive influence on its corporate image, and that positive corporate image had a positive effect on brand loyalty development. However, the recognition of the sponsorship did not have a direct influence on brand loyalty. The friendly corporate image developed by the recognition of the sponsorship consequently could have had an effect on brand loyalty. Therefore, companies should not relinquish investments to corporate image development if they require more brand loyalty. Third, the influence of corporate image on brand loyalty shows stronger results in the shopper group rather than in the merchant group. Psycho-graphic factors of shoppers and merchants might give rise to the difference between the two groups.
