Objective: The aim of this study was to determine the effect of pineapple cannery by-product (PCB) level on the growth performance and carcass characteristics of finishing Hanwoo steers. Methods: The feeding stage was divided into early and late finishing stages. A total of 60 castrated Hanwoo steers (13.9±0.8 months old, 418.8±36.5 kg initial body weight [BW]) were blocked by initial BW and then randomly allotted into 12 pens (five head/pen). The pens were randomly assigned to control (CONT), low PCB (LPCB), or high PCB (HPCB) treatments. These diets contained 0%, 1.5%, or 3.0% of PCB (on a dry matter [DM] basis; as-fed basis was 0%, 10.6%, or 21.2%), respectively. Results: For the early finishing stage, body weight gain (BWG) and average daily gain (ADG) of the CONT and LPCB feeding groups were greater (p<0.05) than those of the HPCB feeding group. In addition, there were linear and quadratic effects on BWG and ADG with increasing dietary PCB level (p<0.05). The gain to feed (G:F) ratio tends to quadratically decrease with an increasing PCB level in the early finishing stage (p = 0.076). Growth performances of late finishing stage were not affected by PCB level. The marbling score of the LPCB feeding group was similar to that of the CONT feeding group. However, there was a linear decrease (p< 0.05) in marbling score and quality grade among treatments as PCB was increased in the diet. In the longissimus muscle free amino acid profile, histidine composition increased linearly (p<0.05) with an increasing level of PCB. Conclusion: The level of PCB 1.5% DM in diet can be used for finishing steers without any adverse effects on growth and carcass performances. However, there were some negative effects on growth and carcass performance in the HPCB feeding group.

Recognizing the lack of empirical studies on the returns to R & D investment in Korean firms, this paper analyzes the relationships between R & D investment and corporate performances measured by sales growth rate, profit rate and PER. The data used here are from 167 firms in 8 different industries covering the period from 1985 to 1989. The results show that the profit rate is strongly correlated with R & D investment. But unlike the results of most studies previously done in the U.S., R & D investment only weakly and insignificantly correlated with sales growth and PER.

본 연구는 실내외 양식방법에 따른 미꾸라지 양식장 모니터링과 성장특성을 조사하여 국내 미꾸라지 양식산업에 대한 기초자료를 확보하고자 수행하였다. 조사는 2017년 8월부터 2019년 10월까지 실내 양식장 1개소 (D-site), 실외양식장 2개소 (P1-site, P2-site)를 선정하여 수행하였다. 성장도 측정결과를 토대로 WG (weight gain), DWG (daily weight gain), and SWG (specific weight gain) 분석한 결과 D-site에서는 175.27±36.2%, 7.98±3.3%, 0.94±0.2%, P1-site에서 320±34%, 4.07±0.6%, 0.55±0.1%, P2-site에서 295.9±53%, 4.15±0.5%, 0.62±0.1%로 나타났다. WG는 실외노지 양식장(P1-Site과 P2-site)에서 높았지만 DWG와 SWG는 실내양식장(D-site)에서 높게 나타났다. 본 조사 결과의 차이는 실내외 양식방법에 따른 성장도, 수질환경, 출하시기 및 횟수 차이로 인한 것으로 판단된다. 특히 실외 양식은 출하시기까지 1년 이상 소요되었으나 실내 양식은 1년에 3회의 출하가 가능한 것으로 나타났다.

Established in 2006 as the forward integration effort by Taesung Industry, the major cosmetic packaging company, TONYMOLY has phenomenally grown to one of the major cosmetic brand companies in the submarket called, 'one brand-shop' of cosmetic market since 2008, after overcoming the crisis of 'going out of business' in a couple of early years. Within a relatively short period of time, TONYMOLY's performances have dramatically improved in terms of metrics such as growth in sales revenue, the number of stores, the average sales per store, transaction value per customer, the number of monthly transactions, the number of membership-based customers, and overseas sales. In this case study, we have examined TONYMOLY's recent marketing activities which may explain the plausible reasons behind the substantial growth of a small but smart cosmetic company. Above all, the first key success factor of TONYMOLY would be found in its adherence to the clear philosophy of the customer value proposition and/or the differentiated position of TONYMOLY as a brand of providing value. Second, this brand concept of value was first penetrated and welcomed among the foothold customer target group of mid and late teens with appropriate products, while the target groups were later expanded into the age group of twenties along with expansion of relevant products. Third, its differentiation efforts have been concrete and meaningful by utilizing unique ingredients in its product development and marketing efforts, unique fun packaging, and continuously introducing new hit-selling products as well as managing steady-selling products. Fourth, TONYMOLY has been smart enough to use its limited marketing money efficiently and effectively in its marketing communication activities. Viral marketing, PPL, and concentrated media planning and execution turned out to produce effective and efficient market-based performances such as awareness, word-of-mouth, and sales. Lastly, the marketing leadership of CEO and top management, emphasizing communications and interactions, was confirmed in the relationship quality with and trust level of its franchisees and internal employees. These key success factors may explain the recent phenomenal market performances of TONYMOLY. Despite recent successes, the major issues are presented for TONYMOLY to consider for maintaining its sustainable advantages and growth. The first issue concerns TONYMOLY's choice of growth philosophy between product/brand-centric marketing and customer-centric marketing. The second challenging issue relates to how TONYMOLY can cope with 'growing pains' plausibly accompanied with the rapid growth.

The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (control), ii) basal diet plus 0.5% garlic powder (GP), iii) basal diet plus 0.5% pennywort powder (PW) and iv) 0.002% virginiamycin (VM). Birds were killed at day 42 and intestinal samples were collected to assess for Lactobacillus and Escherichia coli. The pectoralis profundus from chicken breast samples was obtained from 10 birds from each treatment group on day 42 and frozen at $-20^{\circ}C$ for further analyses. Fatty acid profile of breast muscles was determined using gas liquid chromatography. Feed intake and weight gain of broilers fed with GP, PW, and VM were significantly higher (p<0.05) compared to control. Feeding chicks GP, PW, and VM significantly reduced Escherichia coli count (p<0.05) while Lactobacillus spp count were significantly higher (p<0.05) in the gut when compared to control group on day 42. Supplemented diet containing pennywort increased the C18:3n-3 fatty acid composition of chickens' breast muscle. Garlic and pennywort may be useful in modulating broiler guts as they control the enteropathogens that help to utilize feed efficiently. This subsequently enhances the growth performances of broiler chickens.

The purpose of this study is to investigate the relationship among factors that expand the win-win growth between domestic finished goods-making manufacturers and subcontractors. One-hundred twenty six firms participated for this study and were used for the data analysis. As a result of analysis, first, it was found that the win-win growth between first-tier suppliers and second-tier suppliers has positive effects on the win-win growth made by second-tier suppliers helping the third-tier suppliers. Second, it was found that the win-win growth policies supported by the government for the positive relationship between first-tier suppliers and second-tier suppliers for the finished goods-making manufacturers have positive effects on the win-win growth between second-tier suppliers and third-tier suppliers. Third, the results also showed that the win-win growth between second-tier suppliers and third-tier suppliers has a positive influence both on the financial and on the non-financial performances of the second-tier suppliers. Based on the results of this study, it is recommended to (1) construct infrastructure by sector through partnership between finished goods-making manufacturers and subcontractors, (2) draw in active support through the governmental win-win growth policies, (3) induce increasing productivities through information sharing, manpower support, technical support and educational support, and (4) strengthen and cultivate the culture of the small- and medium-sized companies.

Seeds of chicory were collected and selected with good germination, emergence and productivity. To develop chicory as a new forage crop seeds were primed with polyethylene glycol (PEG 6000) and coated with some chemicals, and tested in laboratory and field. The results obtained are summarized as follows: 1. Among the seed lines collected, PUlgAH, PU21TH, PU37CH and PU30TK were germinated more quickly and took less time for germination than the others. 2. PUI8AH was the best in emergence and growth although PU21TH showed superior germinative ability among the lines collected. 3. Chicory seeds primed with 20~25% PEG solution for three days at $10^{\circ}C$, or the seeds treated with 25% PEG solution at $15^{\circ}C$ regardless the treatment period showed good germination performances. 4. Osmotic priming with PEG accelerated the germination of chicory, but not in the field. 5. Coated seeds geminated more slowly in Petridishes but showed superior emergence and growth to those of primed or untreated seeds. Treatment 3 showed the best performances in pot experiment. 6. Coated seeds showed remarkable increase in establishment and dry matter yield especially in sod sowing compared to the other sowing method. 7. Most nutrient contents except iron and manganese of chicory were much higher than those of mixed pasture .

A four-week feeding trial was conducted to investigate the effects of dietary soybean meal (SBM) and powdered Cheongkukjang (CKJ) on non-specific immune responses of parrotfish Oplegnathus fasciatus. Three isonitrogenous (42% crude protein) and isocaloric (17.1 MJ/kg) diets were formulated to replace fish meal by 0, 25% SBM or 25% CKJ (designated as FM, 25SBM and 25CKJ, respectively). Ninety fish (initial body weight 122 g) were randomly allotted into nine 150 L tanks. One of the three experimental diets was fed to triplicate groups of fish for 4 weeks. After the feeding trial, no differences were observed in growth performances and feed utilization among fish groups. Liver superoxide dismutase activity of the fish fed CKJ containing diet was significantly higher than that of the control groups. DPPH radical scavenging and $Fe^{2+}-chelating$ activities of the experimental diets containing SBM or powdered CKJ were significantly higher than that of the control diet. The results of the present study suggest that dietary inclusion of powdered 25CKJ significantly increased liver superoxide dismutase activity and did not affect the growth performances, feed utilization, morphological parameters, as well as hematological values of parrotfish.
