HAE-06 extract is a mixture of four medicinal plants, namely Lonicerae Folium et Caulis (Lonicera japonica), Scutellariae Radix (Scutellaria baicalensis), Adenophorae Radix (Adenophora triphylla var. japonica), and Polygonati Oddorati Rhizoma (Polygonatum odoratum var. pluriflorum). The HAE-06 extract demonstrated a concentration-dependent relaxing effect and enhanced cAMP production in bronchial smooth muscle that had been stimulated to contract with acetylcholine. Using a blocker, it was confirmed that the effect was through the β2-adrenergic receptor/cAMP/PKA pathway. In addition, it is thought that the HAE-06 extract has a bronchial smooth muscle relaxation effect by reducing the inflow of Ca2+ through the K+ and Ca2+ channels present in the sarcoplasmic membrane. If research continues in the future, it is believed that it will be possible to use it as a material for pharmaceuticals and functional foods.

This study analyzed consumer needs for the development of elderly-friendly HMR products in China. In developing the products, items needed to be improved, types and packages of the necessary products, additional improvements and food preferences were investigated. According to the demographic characteristics of elderly Chinese consumers, these was analyzed as well. A survey was conducted on a total of 370 elderly people, and data analysis was performed using SPSS 18.0 program. Items related to product quality safety, such as “marks of origin by ingredient”, “rich nutrients”, “expansion of letter size of packaging”, “rich nutrients” and “clear manufacturing date and expiration date”, were required to develop HMR products. The types of products that should be developed were porridge and noodles, and the packaging types that should be developed were eco-friendly packaging and recycled packaging. In addition, “low-calorie HMR”, “development of various seasonings”, “use of eco-friendly food ingredients” and “HMR to digest easily” should be improved. The demand for product improvement and food preference showed significant differences according to the degree of education, monthly income and oral health. The results were intended to prepare basic data for setting the direction when developing elderlyfriendly HMR.

The expansion of the online market is expected to change the purchasing environment. The purpose of this study is to examine the difference in the moderating effect of each characteristic on perceived quality and purchase intention according to the group according to product involvement and purchaser age. The first step is to identify the characteristics of online information sources and social media platforms through a literature review. Next, when perceived quality affects purchase intention, we verify the moderating effect according to the characteristics of online information sources and social media platforms. The moderating effect is verified at the stage by dividing it into a group according to product involvement and a group according to age. The following results were confirmed throughout the study: First, perceived quality significantly affects purchase intention. Second, in the relationship between perceived quality and purchase intention, the influence of the moderating effect is different depending on the high-involvement product and the low-involvement product. Third, it was confirmed that there was a difference in the moderating effect of online information sources and social media platforms in the relationship between perceived quality and purchase intention according to age. This study intends to increase consumers' purchase intentions by identifying specific age groups and product groups of involvement and establishing strategies suitable for the characteristics of online information sources and social media platforms.

The development of IOT technology and artificial intelligence technology is promoting the smartization of manufacturing system. In this study, data extracted from acceleration sensor and current sensor were obtained through experiments in the cutting process of SKD11, which is widely used as a material for special mold steel, and the amount of tool wear and product surface roughness were measured. SVR (Support Vector Regression) is applied to predict the roughness of the product surface in real time using the obtained data. SVR, a machine learning technique, is widely used for linear and non-linear prediction using the concept of kernel. In particular, by applying GSVQR (Generalized Support Vector Quantile Regression), overestimation, underestimation, and neutral estimation of product surface roughness are performed and compared. Furthermore, surface roughness is predicted using the linear kernel and the RBF kernel. In terms of accuracy, the results of the RBF kernel are better than those of the linear kernel. Since it is difficult to predict the amount of tool wear in real time, the product surface roughness is predicted with acceleration and current data excluding the amount of tool wear. In terms of accuracy, the results of excluding the amount of tool wear were not significantly different from those including the amount of tool wear.

To meet rapidly changing market demands, manufacturers strive to increase both of productivity and diversity at the same time. As a part of those effort, they are applying flexible manufacturing systems that produce multiple types and/or options of products at a single production line. This paper studies such flexible manufacturing system with multiple types of products, multiple Bernoulli reliability machines and dedicated buffers between them for each of product types. As one of the prevalent control policies, priority based policy is applied at each machines to select the product to be processed. To analyze such system and its performance measures exactly, Markov chain models are applied. Because it is too complex to define all relative transient and its probabilities for each state, an algorithm to update transient state probability are introduced. Based on the steady state probability, some performance measures such as production rate, WIP-based measures, blocking probability and starvation probability are derived. Some system properties are also addressed. There is a property of non-conservation of flow, which means the product ratio at the input flow is not conserved at the succeeding flows. In addition, it is also found that increased buffer capacity does not guarantee improved production rate in this system.

본 연구에서는 지방 산화를 억제하고 품질이 우수한 부세 굴비의 가공법을 개발하기 위해 대두와 멸치의 복합 발효소재를 첨가한 염지제 처리 및 건조 시간에 따른 부세 굴비를 제조하여 품질 특성을 비교하였다. 발효소재 첨가에 따른 염지제와 부세 굴비의 DPPH 및 ABTS 라디칼 소거능은 발효소재의 함량에 따라 증가하였으나, 발효소재 1% 이상에서 부세 굴비의 라디칼 소거능은 유의적인 차이를 보이지 않았다. 발효소재의 함량이 증가할수록 부세 굴비의 아미노태질소 함량은 증가하고 VBN, TBARS, 산가는 감소하는 결과를 나타내나, 발효소재 1% 이상에서 품질의 유의적인 차이가 크지 않으므로 염지제의 발효소재 함량은 1%로 선정하였다. 염지제의 염도에 따른 부세 굴비의 품질을 분석한 결과 염도가 증가할수록 아미노태질소 함량은 증가하고 히스타민, VBN, TBARS, 산가는 감소하는 결과는 나타내며, 염지제의 염도는 품질 개선 효과가 가장 우수한 7% 조건을 선정하였다. 염지 처리 후 건조 시간에 따른 부세 굴비의 품질을 분석한 결 과 건조 시간이 증가할수록 수분은 감소하고 염도, pH, 아미노태질소, 히스타민, VBN, TBARS, 산가는 증가하였다. 그러나 건조 48시간 이하는 수분이 많아 저장성이 낮으며, 건조 96시간에서 히스타민과 산패도의 증가율이 높아지므로 부세 굴비의 건조 시간은 72시간이 적합한 것으 로 판단되었다.

The objectives of this study were: (1) to identify differences in consumer attitudes and intentions to recycle fashion products using three types of recycling (including resale, reform, and donation), and (2) to examine the moderating effects of consumer prosocialness on the relationships between attitude and intention for each type of fashion product recycling. Men and women aged 20 years and over were recruited from a marketing research firm panel. Participants completed an online questionnaire incorporating measures for attitudes and intentions to resale, reform, and donate fashion products, prosocialness, frequency of purchasing fashion products, monthly amount of spending on fashion products, and demographic information. Data from 224 participants were analyzed using SPSS 25.0 and PROCESS macro. The results demonstrated that consumers had significantly different attitudes and intentions depending on type of fashion product recycling. Consumers had more positive attitudes toward donation compared to resale and reform types of recycling. Consumer intentions toward resale and donation were significantly higher than their intention to reform. Furthermore, this study confirmed that the attitude-intention gap in fashion product recycling can be explained by individual prosocialness. The moderating effects of prosocialness on the associations between attitude and intention to recycle were significant. The implications of increasing consumers’ behavior intention to recycle fashion products was discussed and future research suggestions are provided.

In the recent business environment, risks related to product safety problems are increasing. These are arising from various factors such as increasing product and production complexity, supply chain diversification, enhanced PL (product liability) law and strengthening regulations of the government. Accordingly, ISO (international organization for standardization) published standards of PSMS (product safety management system) for suppliers such as ISO 10377 and ISO 10393. Meanwhile, the ISO 9001 QMS (quality management system) was revised in 2015, and it has established itself as an effective tool that can consistently meet the various requirements of stakeholders and promote customer satisfaction. This study aims to suggest an integration framework of QMS and PSMS based on the recent ISO international standards. To this end, firstly, the relationship between QMS and PSMS is studied based on the quality and product safety definitions, PDCA (plan-do-check-act) cycle and risk-based thinking. Secondly, the requirements of ISO 10377 and ISO 9001 are compared and classified as the common and ISO 10377 specific requirements. Finally, integration steps of two systems are suggested and guidelines that can systemize the integrated requirements are presented in the aspect of processes and documentation. This study is expected to be used as a guideline that helps companies those have already acquired QMS certification to build an international-level product safety management system early.

이 연구의 목적은 소득에 따른 베이커리 제품 구매 속성과 형태에 대해서 조사하였으며, 일반적인 사항에서 전체 1,235명 중에서 여성이 59.6%, 남성이 40.4%로 여성이 남성보다 다소 많았다. 베이커리 제품 구매 속성에서 ‘건강관심형’이 40.0%로 가장 많았고, 거주지에서는 대도시 거주자가 ‘맛 관심형'이 35.8%인 반면에 중소도시 거주자는 ‘건강 관심형'(p<0.001)의 45.4%로(p<0.001), 소득이 높을 수록 건강에 대한 관심이 높았다(p<0.001). 베이커리 제품을 구매하는 소비자들은 ‘맛’ 67.1%, ‘영양’ 13.7%, ‘가격’ 7.8% 순으로 거주지에 따라 유의한 차이를 나타내었다(p<0.01). 베이커리 이용형태에서는 프랜차이즈 베이커리가 71.1%, 윈도우 베이커리 14.6%, 인스토어 베이커리 8.4%였다.

포스트바이오틱스(postbiotics)는 프로바이오틱스(probiotics)가 발효과정 중 생산하는 유용한 대사산물과 미생물의 구성성분을 포 함하는 개념이다. 포스트바이오틱스는 기존 프로바이오틱스 소재가 갖는 안전성(safety), 기능성(function), 안정성(stability)의 한계를 극복할 수 있는 새로운 대안 소재로 주목받고 있다. 사균화 처리과정으로, 특정 대사물질의 복합물 형태로 제조되고 있기에 기존 생균제보다 가공, 포장, 유통, 섭취가 용이하다. 면역력이 낮은 환자나 건강 취약 계층의 소비자들도 안전하게 섭취할 수 있는 것도 장점이다. 뿐만 아니라, 체내에서 면역 조절, 감염 방지, 지질 및 콜레스테롤 대사, 항산화 기능을 보이고 있어, 앞으로 건강기능 식품 우수 소재로 활용될 가능성은 더 커질 것이다. 다만, 대부분의 연구들이 아직은 세포실험과 동물시험인 단계이기에 실제 인체적용 시험을 마친 소재들은 적은 편이다. 향후 꾸준한 연구성과를 바탕으로 다양한 기능을 가진 포스트바이오틱스 소재와 제품들이 개발된다면 건강기능식품 산업에 새로운 성장동력이 될 것으로 예상 된다.
