In this study, we propose a technological system designed to provide machine vision-based automatic inspection and autonomous operation services for an entire process related to product inspection in wire harness manufacturing. The smart factory paradigm is a valuable and necessary goal, small companies may encounter steep barriers to entry. Therefore, the best approach is to develop towards this approach gradually in stages starting with the relatively simple improvement to manufacturing processes, such as replacing manual quality assurance stages with machine vision-based inspection. In this study, we consider design issues of a system based on the proposed technology and describe an experimental implementation. In addition, we evaluated the implementation of the proposed technology. The test results show that the adoption of the proposed machine vision-based automatic inspection and operation service system for multi-wire harness production may be considered justified, and the effectiveness of the proposed technology was verified.

In the restaurant industry, along with the fourth industry, there is a food technology craze due to IT development. In addition, many prospective restaurant founders are increasing due to restaurant start-ups with relatively low entry barriers. And ChatGPT is causing a craze for chatbots. Therefore, the purpose of this paper is to analyze factors for restaurant start-ups with big data and implement a system to make it easier for prospective restaurant start-ups to recommend restaurant start-ups that suit them and further increase the success rate for restaurant start-ups. Therefore, this paper is meaningful in analyzing the start-up factors desired by prospective restaurant founders with big data, turning them into text, and furthermore, designing and studying the start-up factors shown as big data into a restaurant start-up chatbot system.

Blockchain technology has paved the way for the rise of non-fungible tokens(NFTs) in recent years. NFTs enable the unique ownership of digital assets and harness the power of blockchain's transparency and decentralization. However, existing NFT platforms often pose barriers to entry for the public due to their technical complexity and high issuance costs. To address the problem, this paper proposes a user-friendly NFT platform with a simplified issuance process. A home page is created to allow easy NFT issuance for anyone. These advancements are expected to foster the growth of the NFT market and facilitate the development of new business models.

The purpose of this study was to analyze career behaviors(job exploration, job hunting) of the need mode in the women's second labor market transition. To obtain this objective 501 women, who quitted their job in 780 women randomly sampling completed questionnaire. To analyze data, $x^2$, ANOVA were executed. Research results were explained, there were no difference career behaviors, experience of career counseling, experience of career education, aspiration of career behaviors by the need mode in the women's second labor market transition. But, there were difference motivation of labor market entry, career barriers, preference of occupations, level of job competence of career behaviors by the need mode in the women's second labor market transition. The implications of the results on women's second labor market transition of developing career education and counseling programs were discussed and finally suggestions for further study were made.

Additive manufacturing(AM) can create complex shapes directly in 3D CAD models with internal geometry compared to conventional subtraction manufacturing. AM technology has the advantage of adopting various materials as well as the reduction of material. However, the high cost of AM is still a significant barrier preventing the wider adoption of AM in industries. This paper analyzes the technical application cases for solving these entry barriers and proposes a bi-metal 3D printing technology as an anticipated application to overcome the difficulty. The paper investigates the complications for current 3D metal printing technology to conduct bi-metal 3D printing and addresses ongoing solution research based on laser technology.

Purpose - This paper empirically investigates the relationship between firm productivity and importing intermediate inputs in the Korean manufacturing sector. Design/methodology - This paper tests the two related hypotheses on the relationship between importing and productivity for a sample of Korean manufacturing firms. We test the self-selection hypothesis by comparing pre-entry levels of productivity between importers and non-importers. We test the learning-by-importing hypothesis by employing propensity score matching with differencein-differences approach. Findings - Future importers are more productive than future non-importers years before they start to import, which supports the self-selection hypothesis. In contrast, there is no strong evidence for learning-by-importing. Originality/value - This paper is the first study to explore the relationship between importing and firm-level productivity for Korean firms. The results have an important implication on trade policies to lower or raise trade barriers in imported inputs.

최근 벤처 기업에 대한 관심이 급증하면서 이들의 성공요인에 대한 연구들이 많아지고 있으며, 인터넷 비즈니스 산업도 많은 벤처기업을 배출한 산업 가운데 하나이다. 이 산업의 경우, 신규진입의 용이성으로 인하여 진입장벽이 거의 없는 산업으로 알려져 왔다. 그러나 실제 선점 기업들의 가시적인 성과가 나타남에 따라 본 연구는 이 산업에서의 진입장벽 존재 여부와 그 영향력에 대하여 알아보고자 한다. 보다 구체적으로 인터넷 비즈니스산업의 벤처기업이 가지는 진입장벽을 기존 문헌 연구 및 벤처기업 5개사와의 FGI(Focus Group Interview)를 통하여 연구개발 및 기술력(특허권), 브랜드력, 고객 전환비용, 창업자(인맥), 전략적 제휴의 5가지 변수로 압축하였다. 이들 5개 변수가 초기 진입자에게 실제 혜택을 주는가, 이들 5가지 진입장벽의 중요성은 동일한가, 그리고 이들 진입장벽이 서로 다른 사업 유형의 벤처 기업들 진입의사결정에. 동일한 영향을 주는가의 가설이 제시되었다.

This study analyzes factors that affect the corporate value of Korean companies operating in Latin American countries. Primary factors are associated with characteristics of the host country, the parent company, and subsidiaries. Empirical results show that asset specificity is the main factor influencing firm value. This region is geographically far from Korea and culturally different. Therefore, the source of competitive advantage such as asset specificity should be large enough to offset liability of foreignness for successful entry into the region. This paper also found that joint ventures are more advantageous than direct investments. Joint ventures in Latin American can minimize risk, complement technology and information, and reduce trade barriers.

In this study, the core competencies of 7-Eleven, Japan's representative convenience store, were derived through a qualitative analysis method using VRIO (value, rarity, Imitability, and organization) framework, a management strategy model based on Resource-Based View (RBV). As a result of VRIO analysis, the value can be based on the scale that 7-Eleven ranks first in the Japanese convenience store industry in terms of the number of stores and market share that it has developed based on capital. The rarity is based on the fact that raw material procurement, the main activity of a company, is establishing the nation's largest distribution channel in the entire process, from producers to logisticians and franchisees. The difficulty for Imitability is based on a dominant strategy and has secured a competitive advantage by opening stores in a specific area, improving awareness, and raising barriers to entry. As the largest company in the convenience store industry, it is confirmed that 7-Eleven is the result of organizational power that has built stores not only in Korea but also in 16 countries around the world.

As the paradigm of future vehicles changes, the interest in automotive semiconductor, which plays a key role in realizing this, is increasing. Automotive semiconductors are the technology with very high entry barriers that require a lot of effort and time because it must secure technology readiness level and also consider safety and reliability. In this technology field, it is very important to develop new businesses and create opportunities through technology trend analysis. However, systematic analysis and application of automotive semiconductor technology trends are currently lacking. In this paper, U.S. registered patent documents related to automotive semiconductor were collected and investigated based on the patent's IPC. The main technology of automotive semiconductor was analyzed through topic modeling, and the technology path such as emerging technology was investigated through cosine similarity. We identified that those emerging technologies such as driving control for vehicle and AI service appeared. We observed that as time passed, both convergence and independence of automotive semiconductor technology proceeded simultaneously.
