Recently, as the complexity of system becomes increased, it becomes important to manage, track, and control the configuration information of various assets of complex systems such as plant and factory over system lifecycle. We call it configuration management (CM). CM enables us to establish and maintain the consistency of a system’s functional and physical attributes with its design requirements, and operational information throughout its lifecycle. In this study, we look through the main concept of CM and relevant research works. Also, we address the CM processes suitable to small-and-medium sized plant in terms of modeling viewpoint.

This study investigates the effects of isothermal holding temperature and time on the microstructure, hardness and Charpy impact properties of medium-carbon bainitic steel specimens. Medium-carbon steel specimens with different bainitic microstructures are fabricated by varying the isothermal conditions and their microstructures are characterized using OM, SEM and EBSD analysis. Hardness and Charpy impact tests are also performed to examine the correlation of microstructure and mechanical properties. The microstructural analysis results reveal that granular bainite, bainitic ferrite, lath martensite and retained austenite form differently in the specimens. The volume fraction of granular bainite and bainitic ferrite increases as the isothermal holding temperature increases, which decreases the hardness of specimens isothermally heat-treated at 300 ℃ or higher. The specimens isothermally heat-treated at 250 ℃ exhibit the highest hardness due to the formation of lath martensite, irrespective of isothermal holding time. The Charpy impact test results indicate that increasing isothermal holding time improves the impact toughness because of the increase in volume fraction of granular bainite and bainitic ferrite, which have a relatively soft microstructure compared to lath martensite for specimens isothermally heat-treated at 250 ℃ and 300 ℃.

Introduction Advertorials promote products by appealing-to and entertaining audiences. These ads increasingly target children aged 5 and younger, a segment of growing importance due to their influence on family buying decisions (McNeal, 1999). A new type of advertorial can be described as video advertisements (videotisements) and currently appear in online channels like YouTube that receive little regulation. They feature products like the Minecraft game or Barbie doll as the main story-line element, with many being viewed tens of millions of times. Videotisement hosts may produce thousands of episodes that feature the same game/doll, forming miniseries encouraging children to return and watch. Videotisements differ from “online influencers”, they exclusively promote one product over a long period (years) and use storylines to demonstrate product use. Advertisers have long promoted products through entertainment shows. This format has been stable for a long time, only recently morphing into videotisements. In the 1950s, TV shows like The Mickey Mouse Club carried embedded persuasive messages (Palmer & Carpenter, 2006). In the 60s, children’s TV featured products like toys. By the 70s, companies were conducting research into ways to attract children, trying to convert their interest into sales. This led the FTC to suggest, in 1978, banning children’s advertising. This proposal accelerated academic research into how children processed TV programs and ads (Ward, Wackman, & Wartella, 1977). These studies investigated covert product placements in shows or movies, lyrics, books (Gupta & Gould, 1997) and online media (Balasubramanian, Karrh & Patwardhan, 2006). Product placements could increase sales, overcome consumer ad resistance and media-fragmentation (Palmer & Carpenter, 2006). This prompted studies of attitudesto (Gupta & Gould, 1997) and effectiveness-of placements (Russell, 2002). There were also unsuccessful calls to ban or disclose placements. The early 2000s saw child-targeted ads flowing to the internet; young children were consuming more web-entertainment and less TV, 80% of children below age 5 used the internet at least once a week (Gutnick, Robb, Takeuchi, & Kotler, 2011) to play games online (Marsh, 2010). The web enabled advertisers to interact directly with children by providing ads that masqueraded as games (advergames), containing commercial logos, mascots and trade characters (Mallinckrodt & Mizerski, 2007). Advergames quickly became among the top five ways to reach children (Vanwesenbeeck, Walrave, & Ponnet, 2017). Some advertisers also started “online communities where children can meet and interact with new and existing friends and play games” (Rozendaal, Slot, van Reijmersdal, & Buijzen, 2013, p.142). Some advergames are distributed through social media like Facebook (Terlutter & Capella, 2013) and its “stealthy nature” (Hudders, Cauberghe, & Panic, 2016) has attracted ethical and regulatory attention (Swanepoel, Lye, & Rugimbana, 2009). The advergame market is now cluttered and advertisers have moved to videotisements. We know very little about this format, this is the impetus for our preliminary study about how children use videotisements. These findings will lead to a more comprehensive study. A videotisement is typically posted on YouTube, Youku and Tudou. The entire video is a covert ad. A host narrates entertaining product information, as the product is used/played with. This is attractive to young children because the videotisement mimics watching other children play – just like watching their friends play games. The clips look professionally produced, suggesting some are linked to product manufacturers (see www.youtube.com/watch?v=w7FX_EnrW1k). A comparative format is the TV infomercial. However, infomercials declare as advertising that sells products – you can order by calling the advertised phone number – videotisements do not do this. Videotisements are produced as video-series. The episodes explore different areas or versions of a game/toy and build on earlier episodes, encouraging children to revisit to follow the story. In some cases, the host becomes a celebrity. For example, Grace Mulgrew who hosts the Grace’s World YouTube channel has over 1 billion views from more than a million subscribers (Stewart, 2018). The episodes show Grace (an “ordinary” 12-year-old) playing with her Barbie dolls. As the storylines develop, Grace displays the latest Barbie characters and accessories. Barbie provides Grace with free dolls and YouTube works with Grace to produce kid-friendly content and educational clips (House, 2015). However, Grace’s World hides these ties. She continues to create, post and promote Barbie videos. Stealthy videotisements are now common; YouTube hosts 56 million videotisements for the Minecraft game. Most of these ads are watched hundreds of thousands of times within the first week, and millions of times by the second week after release. Videotisements also contain commercials and web advertising and children are encouraged to provide personal contact information for membership, competitions or free gifts. So far, this format has not received any attention from researchers. We seem to be the first to study this media and explore children’s exposure-to and preference-for videotisements. Observation of the authors’ children suggest that there is brand preference, the children only watch videos featuring certain games with certain hosts. Socialisation to Videotisements Video sharing sites like YouTube are among the first that children below age nine visit (Holloway, Green, & Livingstone, 2013); two thirds of children watch videos on these sites (Hoh, 2017). On average, children up to age two watch games and videos online for two hours daily (Brown, 2011) and five to fifteen year olds are online for 15 hours each week (Ofcom, 2016). Typically, parents enable young children’s access to the web through their phones and tablets, socialising (Sonck, Nikken, & de Haan, 2013) and guiding (Shin & Li, 2017) them to certain content. The frequency of parental and child internet use is positively correlated (Holloway et al., 2013). Older siblings also socialise younger siblings to media and influence what the younger ones do online (Wartella, O’Keefe & Scantlin, 2000); unsurprisingly children with older siblings start using the internet at a younger age (Teuwen, De Groff, & Zaman, 2012). Consequently, three year olds are knowledgeable about multiplayer networked games like Plants vs. Zombies, Minecraft and Mario long before they attain the dexterity to play the games (Dickey, 2007). One way socialisation occurs is when siblings watch videotisements together, these videos are attractive to younger children who cannot yet play the game – they can participate by watching. This raises our research question: What is the level of young children’s exposure to videotisements? Methodology As two to five year olds cannot respond adequately about their videotisement use, we surveyed their parents/carers. Respondents were informed of the study’s purpose, providing written consent in the way approved by the University Research Ethics Team. [Insert Table 1 about here] Parents were recruited from early childhood learning centres in Singapore (n = 31), a childcare centre and a convenience sample in Australia (n = 17). They were asked about the number of media devices they had at home (access), the amount of time spent using these devices (use), whether the child observes or plays with other children when using these devices (socialisation). We also asked whether parents and siblings watched videotisements with the child (socialisation). Parents answered only about their youngest child. The children’s mean age was 3.12 (SD = 1.07), there were 19 girls (40%) and 29 boys (60%). Most parents were in full time work (Singapore 90%, Australia 88%) and university qualified (Singapore 66%, Australia 82%). All respondents possessed internet enabled devices in their homes that the child could access (Table 1). Results A chi-square analysis showed no significant differences between the Singapore and Australia children’s use of media during weekdays (X2 = 1.357, p>.5) or weekends (X2 = 2.212, p>.5), thus we combined the responses for analysis (n = 48). TV was the most popular media, 88% watched on weekdays and 94% on weekends. Videos and videotisements was ranked second and third, followed by playing video/digital games and playing online (Table 2). [Insert Table 2 about here] In our sample, 38% have watched videotisements with others, with 56% of this group watching with parents and 22% with siblings (Table 3), 66% of our sample’s parents watched videotisements with their child. Thirty three percent of the children had older siblings, 21% (n=7) of this group watched videotisements together. [Insert Table 3 about here] Conclusion This article provides one of the first looks at children younger than age five’s use of videotisements. While the sample size was small (n = 48), 100% of the parents surveyed in Singapore and Australia responded that their youngest child watched YouTube or videotisements. This gives a strong indication about the level of videotisement use by young children. Parents and siblings help socialise younger children to these ads. The unregulated and stealthy nature of this ad format calls for more investigation of the format, especially by more vulnerable young child audiences. This paper provides a starting point for research into this emerging ad format. Future research may investigate how videotisements influence children’s buying behaviour and family buying decisions; children’s susceptibility to videotisements; and international patterns of videotisement consumption.

Ampelopsis brevipedunculata (Maxim.) Trautv., also known as porcelain berry, has been used for many years as herbal folk medicine to treat liver diseases. This study was conducted to assess the influence of various factors on the rooting of hardwood stem cuttings of this plant species, collected from Jeju Island (Korea). Three experiments were conducted: (1) Stems of three diameters (≤ 4.5, > 4.5 – < 6.5, or ≥ 6.5 mm), (2) four types of rooting media [rockwool cubes, perlite, peat moss + perlite (3:1, v/v), or vermiculite] and (3) indole-3-butyric acid (IBA) at four treatment concentrations (0, 100, 200, or 400 mg·L-1). For the IBA concentration experiments, cuttings of the various diameters were inserted to a depth of 2 cm in a commercial propagation medium in 72-cell plug trays. The planted stem cuttings were initially placed on a fog bench for 16 days at 95% ± 5% relative humidity at a temperature of 25°C ± 3°C under 95% shade. The stem cuttings were then transferred to a greenhouse bench under ambient light and fed a nutrient solution on a daily basis for 2 weeks. Among the tested stem diameters, cuttings with a stem diameter ≥ 6.5 mm produced the largest stem diameter (2.6 mm) of new shoot, but without root growth. Initial stem diameter significantly affected the length of the new shoot, and the longest shoot length (67.8 mm) was observed in cuttings with an initial stem diameter of ≥ 6.5 mm. Cuttings inserted in vermiculite produced the largest diameter of new shoot (2.4 mm), whereas cuttings grown in rockwool cubes produced the shortest, stem diameter of new shoot growth (1.9 mm). No significant differences (p ≤ 0.05) were observed in the length of new shoot growth among the various rooting media and IBA concentrations. Furthermore, all tested IBA concentrations failed to induce rooting. Collectively, these results suggest that porcelain berry cuttings with an initial diameter of ≥ 6.5 mm have higher survival and bud break, but they did not produce rooting. Further studies are needed to optimize the protocol for the rooting of hardwood stem cuttings of A. brevipedunculata (Maxim.) Trautv.

In this study, a correlation between execution of quality management activities and their results was verified by applying the Malcolm Baldrige model (hereafter referred to as the MB model) as a quality management performance measurement indicator for small and medium enterprises (SMEs) in South Korea. To achieve this goal, we need to determine whether the categorical requirements in the MB model are recognized consistently in SMEs, as a prerequisite. To this end, factor analysis was conducted for measurement variables in each category, which revealed that the process indicator was made up of six factors and the outcome indicator was made up of five factors, like those configured in the MB model. This result can be interpreted to mean that the requirements in each category of the MB model were well produced and recognized consistently throughout SMEs in South Korea. In addition, the analysis of causality between the process indicator (quality management activities) and the outcome indicator (management results) showed high causality between them. Although the quality management levels of SMEs in South Korea are inferior to those of conglomerates or other national quality award-winning companies, this study is significant in that the causality between quality management activities and results was verified, since this study targeted SMEs in South Korea as the target of investigation. Thus, it is empirically proven that the MB model can contribute to improved management results for SMEs in Korea.

상토에 기비로 혼합된 질소 시비수준 차이가 ‘녹광’ 고추의 플러그 묘 생장에 미치는 영향을 구명하기 위해 본 연구를 수행하였다. 코이어더스트, 피트모스 그리고 펄라이트를 용적기준 35, 35 및 30%로 혼합한 상토를 조제할 때 질소를 0, 100, 250, 500, 750, 1,000 및 1,500mg·L-1로 농도를 조절하여 첨가하였고, 질소를 제외한 필수원소는 모든 처리에서 동일한 농도로 조절하였다. 비료를 포함한 상토를 50-cell 트레이에 충진한 후 종자 를 파종하였다. 파종 후 매주 pH와 EC 측정, 파종 0, 3 및 7 주 후 상토의 다량원소 농도 분석, 그리고 파종 7 주 후에 지상부 생장 조사와 식물체 무기원소 함량을 분석하였다. 파종 전 상토의 pH는 질소수준별 차이가 크지 않았지만 육묘기간이 길어질수록 처리간 차이가 커지는 경향이었다. 상토의 EC는 파종 전 질소 시비수준 별 뚜렷한 차이를 보였지만, 파종 4주 이후부터 처리간 차이가 적어졌고, 7주 후에는 모든 처리에서 유사한 수 준으로 측정되었다. 상토 추출용액의 NH4-N 및 NO3-N 농도는 EC와 유사한 경향을 보이며 낮아졌고, 다량원소 농도 역시 파종 3주 이후에 감소폭이 더 커졌다. 파종 후 7주 후 조사한 고추 유묘의 지상부 생장은 500 및 750mg·L-1 처리구에서 우수하였으며, 1,000mg·L-1 이상의 처리구에서는 질소 무시비구와 비슷한 수준으로 생장이 저조하였다. 파종 7주 후 분석한 식물체내 N 함량은 질소 시비수준이 높아질수록 직선적으로 증가하였으며, 지상부 생장이 우수하였던 500 및 750mg·L-1 시비구가 각 각 5.13 및 5.31%로 분석되었다. 이상의 결과를 고려하 였을 때 고추의 유묘 생장을 위해서는 기비로서의 질소 시비수준을 500 또는 750mg·L-1으로 조절하는 것이 바람직하며, 건물중에 기초한 N 함량이 5.1~5.3% 수준으 로 시비농도를 조절하는 것이 바람직하다고 판단하였다.

최근 강원도에서 생산되기 시작하는 잎새버섯의 수확후배지를 활용하여 산업곤충의 한 종인 장수풍뎅이의 사육가 능성을 알아보고 장수풍뎅이 사육농가의 유충먹이 구입 시 경제적 비용절감 및 버섯재배농가의 부산물활용에 따른 신 소득을 창출하고자 시험을 추진하였다. 잎새버섯 배지는 참나무 85%와 밀기울 15%의 조성으로 이루어져 장수풍뎅이의 사육에는 무리가 없어 보였으며, 실제 유충 2령충을 4개월 사육한 결과 개체중이 21.6g으로 대조배지(참 나무발효톱밥) 개체중 20.2g보다 양호하였으며 폐사율도 낮게 나타났다. 유충의 가능한 사육밀도를 알아보기 위해 일반적으로 제시하는 밀도(75마리/60L)를 기준으로 0.5, 1.5배의 밀도를 사육한 결과 60L용기에 100마리 정도 사육이 가능하였다. 성충의 암수비율에 따른 산란시험에서는 암수비율 동일조건에서 산란수가 많았으며 잎새버섯 수확후배 지에서보다는 참나무 발효톱밥에서 산란이 양호하였다. 또한 산란효과를 높이기 위해 시판젤리에 여러 가지 첨가제를 넣어 시험한 결과 흑설탕을 첨가한 먹이조건에서 산란이 좀 더 양호한 것으로 나타났다.

In order to develop solid mass cultivation technology that maximizes insecticide of entomopathogenic nematode(EPN) isolated from Korea, we have studied the optimization of solid culture medium and production conditions. The optimized conditions from the harvest yields and the insecticidal activity against the Galleria mellonella larvae were yeast extract 2.0%, soybean flour 20%, whole milk powder 3%, olive oil 5% and egg yolk 5%. It was also found that the optimum condition of the carrier(polyurethane) content was about 8-12%, the culture time of symbiotic bacteria was about 48 hours, and the inoculation concentration of nematode was 4,000-5,000 per g medium. And the optimal harvesting point in solid culture conditions was confirmed after 12 days of inoculation.

Dianthus caryophyllus (carnation) is a globally important ornamental plant. Tissue culture techniques have been used for the commercial production of carnation; however, the micropropagation of carnation has been impeded due to the occurrence of hyperhydricity during the shoot multiplication process or micropropagation stage 2. In the present study, the effects of different concentrations of rare earth elements on the reduction of hyperhydricity in micropropagated carnation were investigated. Nodal explants of D. caryophyllus ‘13827’ were cultured on Murashige and Skoog medium containing 1.0 mg·L-1 6-benzyladenine and 0.5 mg·L-1 indole-3-acetic acid with 3.0% (w/v) sucrose and 0.8% (w/v) agar (control medium). The medium was supplemented with lanthanum nitrate, La(NO3)3, cerium nitrate, Ce(NO3)3, or neodymium chloride, NdCl3 at a concentration of 0.05, 0.1, or 0.15 mM. Hyperhydricity was observed in 68.9% of the cultures produced on the control medium. The lowest percentage (42.2%) of hyperhydricity was observed in plants propagated on the medium supplemented with 0.05 mM Ce(NO3)3. Furthermore, the soluble protein concentration was higher in both the non-hyperhydric and hyperhydric plants produced on the medium supplemented with 0.05 mM Ce(NO3)3, whereas the activity of catalase, guaiacol peroxidase, and ascorbate peroxidase was lower in comparison with the media lacking Ce3+. The results of this study suggest that supplementation of the culture medium with 0.05 mM Ce(NO3)3 alleviates oxidative stress and reduces hyperhydricity in carnation during the adventitious shoot multiplication stage.

본 실험은 농가 관행인 굴삭기를 이용한 뒤집기와 교반기 시제품를 이용한 뒤집기와의 비교 시험을 통해 발효단계별 배지의 특성을 조사하였다. 배지내 온도변화는 굴삭기를 이용한 3차 뒤집기까지는 처리간에 온도의 변화 차이가 거의 없었지만, 4차와 5차 뒤집기에서는 교반기 시제품을 이용하여 뒤집기를 한 처리구에서 온도 상승이 빨라지는 경향을 보였다. 야외발효 단계에서 배지에는 고온성 세균 (Bacillus spp.), 방선균, 형광성 Pseudomonas 속, 사상균 등 다양한 미생물들이 분포하였고, 특히 배지발효 과정에서 배지의 분해와 발열에 호기성 세균의 분포는 2차 뒤집기에서 가장 높은 밀도를 보였고, 발효가 진행되면서 밀도는 감소하는 경향을 보였다. 교반기를 활용한 배지의 호기성 세균과 형광성 Pseudomonas 속은 굴삭기 뒤집기와 뚜렷한 차이가 없었고, 고온성 세균과 고온성 방선균은 교반기 뒤집기에서 조금 높은 밀도를 보였다. 처리별 볏짚의 길이는 교반기 시제품을 사용하였을 경우 조금 짧았고, 수분함량도 교반기 시제품을 사용하였을 때 낮았다. pH와 EC는 처리간에 뚜렷한 차이를 보이지 않았으며, L값과 a, b값은 교반기 시제품으로 뒤집기가 진행될수록 높아지는 경향을 보였다.

본 연구는 우량묘 생산을 위해 신개발된 인공배지와 육묘용 배지의 이화학적 특성을 비교하고 적정 관수 간격을 구명하기 위해 수행되었다. 5종의 기존 인공배지 (유기배지인 coir, 혼합배지인 Tosilee와 Q plug, 그리고 무기배지인 LC와 rockwool)와 4종의 신개발 배지(혼합 배지인 TP-S1, 그리고 무기배지인 PU 14-S1, PU-7B, PU 15-S1)를 이용하여 토마토(Solanum lycopersicum L.) ‘예광’을 육묘하였으며, 14일간 1일(14회), 2일(7회) 그리고 3일(5회) 간격으로 관수 처리하였다. pH는 PU 15-S1 배지에서 유의성 있게 가장 높았으며, 모든 배지 에서 pH 5.17-6.90의 범위였다. EC는 Q plug 배지에서 가장 높게 나타났다. 초기발아율은 PU 15-S1 배지에서 가장 우수하였다. 최종발아율과 평균발아수는 PU 14-S1 배지를 제외하고는 모든 배지에서 유의적인 차이가 없었다. 파종 후 15일째 토마토 묘의 생육은 Q plug 배지에 서 우수하였다. 파종 후 29일 째 묘의 생육 또한 Q plug 배지에서 유의적으로 우수하게 나타났고, 다음으로 rockwool과 PU-7B 배지에서 우수하였다. 또한 생육은 1일 간격 처리에서 가장 우수한 경향을 보였다. 결과적으로 본 실험에서 토마토 육묘 시 인공배지의 적용가능성을 확인하였으며, 묘의 생육은 Q plug 배지에서 가장 우수하였다. 신개발된 PU-7B 인공배지에 양분을 첨가하고 1일 간격으로 관수한다면 Q plug 배지의 결과와 같이 우수한 토마토 묘를 생산할 수 있을 것으로 판단된다.

In this study, we investigate the potential use of persimmon peels (PP) in mushroom culture medium for the production of functional mushrooms. Pleurotus eryngii was cultivated in medium supplemented with PP (SMPP) at the following concentrations: 0% SMPP (control), 5% SMPP, 10% SMPP, 15% SMPP, 20% SMPP, or 30% SMPP. The total polyphenol content, DPPH radical scavenging ability, ABTS cation scavenging ability, and reducing power of P. eryngii cultivated in SMPP were investigated. P. eryngii cultured in 20% SMPP produced the highest values for all four measurements. Total polyphenol content, DPPH radical scavenging activity, ABTS cation scavenging ability, and reducing power all increased upon the addition of PP. Based on our results, we can conclude that persimmon peels are a highly valuable supplement for functional mushroom culture medium.

As the competitiveness of SMEs (small and medium enterprises) is getting more and more improved and globalized, the government provides various consulting services to secure the competitiveness of small and medium firms and support stable growth. However, the assessment of the result from the government’s support is generally focused on non-financial factors, such as customer satisfaction and analysis of improvement effect. This paper is in regards to the statistical analysis of how much the government’s support in the form of providing consulting services contributes to financial outcomes in terms of profitability and growth. ROA (return on asset) and ROS (return on sales), which are investment profitability and sales profitability respectively, are chosen as an indicator of profitability. For analysis of growth, sales revenue and total asset growth are used. The samples are 44 corporations which are supported by government, and 150 corporations which are selected for comparison, with corporate growth support center program by the Ministry of Trade, Industry, and Energy chosen as the consulting model. After gathering the yearly balance sheets and income statements of the samples from CRETOP, Korea Enterprise Data, the analysis is conducted in the way of identifying the statistical significance of financial difference in the same period between corporates taking consulting services and corporates which have not, and the difference of financial outcomes from the corporates taking consulting services before and after consulting services. As a result, in terms of business growth, it is turned out to have positive difference both in growth ratio and profitability compared to the compared corporations at the significant level. Therefore, it is obvious that the consulting program which government provides to SMEs have direct influence practically to the corporates’ management performance.

내건성이 우수하다고 판명되어진 비수리(Lespedeza cuneata), 새(Arundinella hirta), 소리쟁이 (Rumex crispus), 장구채(Silene firma), 매듭풀(Kummerowia striata) 5수종의 기내대량증식 조건을 구명하였다. 5종의 선발종 중 비수리는 WPM배지에서 길이생장이 가장 좋았으며, 새는 MS배지, 소리쟁 이는 LP배지에서 장구채는 LP배지, 매듭풀은 SH배지에서 좋은 길이생장을 보였다. 뿌리발생도 수종에 따라 배양배지에 따라 다르게 나타났다. 비수리의 경우 기내발근은 모든 배지에서 뿌리가 발생하지 않 았으며, 새는 MS배지, 소리쟁이는 WPM배지, 장구채는 MS배지, 매듭풀은 1/2MS배지에서 가장 좋은 뿌리생장을 보였다. 잎 갈변은 비수리는 B5배지, 새는 WPM배지, 소리쟁이는 B5배지, 매듭풀은 LP배 지에서 가장 심한 갈변을 보였다. 생존율은 비수리, 소리쟁이, 장구채는 모든배지에서 100% 생존율을 보였으며, 새는 WPM배지에서 25% 생존율을, 매듭풀은 LP배지에서 25%의 낮은 생존율을 나타냈다. 선 발종의 다경줄기를 유도하기 위해 cytokinin을 처리한 결과 비수리의 경우 TDZ 0.5mg/L 처리구, 새는 BA 0.5mg/L, 소리쟁이는 TDZ 0.1mg/L, 장구채는 BA 0.5mg/L, 매듭풀은 BA 0.5mg/L 처리구에서 가장 많은 다경줄기를 형성하였다. cytokinin 처리는 줄기생장, 기내발근 및 다경줄기 유도에 영향을 미쳤다. 기내에서 배양된 식물체는 4종의 인공상토에서 성공적으로 순화되었다. 본 연구 결과들은 내건 성을 가진 5종의 유용식물의 품종개발 및 대량증식에 크게 기여할 수 있을 것으로 판단된다.
