As of the end of August 2017, there were 392 academic articles for $4^{th}$ Industrial Revolution in Korea. Is the vigorous discussion on the 4th Industrial Revolution in Korea normal? We checked the main theories on this topic by existing theories and responses of major countries and industries. The findings are that there are technologies called a Technological Revolution, and the industrial application of some technologies is in the starting stage. If comes, the Industrial Revolution is expected with the structure as follows: excellence science, core technologies, base technologies, application and infrastructure, and institutions. Nonetheless, the brisk studies are from three branches such as the Industry 4.0, social connection and artificial intelligence. The Industry 4.0, the digital transformation of manufacturing is the on-going issue in the industry, and artificial intelligence brings the biggest discourse. The 392 literature are mostly from introduction and preparation for future; technology 15.8%, industry 26.3%, society 24.5%, education 19.1%, policy 10.7%. The labor and employment is only 3.6%.

In this study, lipid classes and fatty acids composition in viscera and muscle of the philippines Pinkgray goby, Amblychaeturichtys hexanema were determined. The viscera contained high levels of total lipid $(TL,\;4.8\%)$, while the muscle contained less TL $(0.5\%)$. TL in the viscera consisted of triacylglycerol $(83.9\%)$, diacylglycerol $(7.9\%)$, polar lipid $(7.4\%)$, and cholesterol $(0.8\%)$. However, the muscle contained a small amount of TG $(3.0\%)$ and much more PL $(73.8\%)$. Principal fatty acids composition of PL and NL in the viscera and muscle were 16:0, 16:1n-7, 18:0, 18: 1n-9, 18:1n-7, l8:3n-3, 20:5n-3, 22:5n-3, and 22:6n-3.

We analyzed the compositions of proximate and total fatty acids in the reproductive organs of male (testis, vas deferens, seminal vesicle, and spermatophore sac) and female (ovary, oviduct, oviducal gland, and nidamental gland) common squid. The protein contents were 12.1-22.7 and 13.2-19.4% for males and females, respectively, and the lipid contents were 1.0-2.7 and 2.1-8.0%, respectively. The prominent fatty acids in all reproductive organs were 22:6n-3, 20:5n-3, 16:0, 20:1n-9, 18:0, 18:1n-9, and 20:4n-6. Females had 28.6-32.0% of 22:6n-3 and 11.3-22.6% of 20:5n-3, while males had 20.8-26.8% of 22:6n-3 and 14.4-28.7% of 20:5n-3. These results indicate that the reproductive organs of both male and female squid are potential sources of n-3 polyunsaturated fatty acid.

Busan is Korea's No. 1 trading port, and the logistics industry plays an important role in the regional industry as a whole. In Busan, various efforts are being made to revitalize the port logistics industry, but it is necessary to develop various policies and related technologies linked with the 4th industry. In this study, we propose a smart refrigeration logistics center, which is required for the activation of Busan New Port and the new port of Pusan New Port, which is connected with the 4th industry. I would like to present the operation direction of the center.

One of the core pillars of the Fourth Industrial Revolution is the innovation of the manufacturing industry. From the beginning, the 4th Industrial Revolution appeared in Germany under the concept of 'Industrial 4.0', which means a radical change in the manufacturing industry that can provide super intelligent product production and services based on artificial intelligence and big data. Since manufacturing innovation is a change in the industrial character of the entire nation, the initial role of government is important. Korea also has various policies related to the 4th Industrial Revolution, but there are still various problems to be solved. Therefore, this paper monitors and analyzes the public R&D projects of the advanced countries on manufacturing innovations in the background mentioned above, and through this, the policy implications are drawn.

Variation Analysis (VA) is used to simulate final product variation, taking into consideration part manufacturing and assembly variations. In VA, all the manufacturing and assembly processes are defined at the product design stage. Process Capability Data Bases (PCDB) provide information about measured variation from previous products and processes and allow the designer to apply this to the new product. A new challenge to this traditional approach is posed by the Industry 4.0 (I4.0) revolution, where Smart Manufacturing (SM) is applied. The manufacturing intelligence and adaptability characteristics of SM make present PCDBs obsolete. Current tolerance analysis methods, which are made for discrete assembly products, are also challenged. This paper discusses the differences expected in future factories relevant to VA, and the approaches required to meet this challenge. Current processes are mapped using I4.0 philosophy and gaps are analysed for potential approaches for tolerance analysis tools. Matching points of simulation capability and I4.0 intents are identified as opportunities. Applying conditional variations, incorporating levels of adjustability, and the un-suitability of present Monte Carlo simulation due to changed mass production characteristics, are considered as major challenges. Opportunities including predicting residual stresses in the final product and linking them to product deterioration, calculating non-dimensional performances and extending simulations for process manufactured products, such as drugs, food products etc. are additional winning aspects for next generation VA tools.

This study is conducted to monitor the morphological developmental features of the egg development, larvae and juvenile of Epinephelus septemfasciatus, the fertilized eggs were gotton using artificial insemination. Matured parents are collected from marine caged fish farms in Geomun-ri, Samsan-myeon, Yeosu-si, Jeollanamdo Korea in June 2012. The fertilized eggs were pelagic eggs containing one oil globule, and measured 0.81~0.89 mm ($0.85{\pm}0.04mm$, n=50) in diameter. In regard to rearing environment, the water temperature is $21.0{\sim}23.0^{\circ}C$ and the salinity is 32.0~33.2‰. Hatching was observed from 48 hours after fertilization, the mouth and anus of prelarvae was not opened but had egg yolk at newly hatched. 4 days after hatching, the mouth and anus of postlarvae was opened and began to eat Rotifer and was measured 2.40~2.49 mm ($2.45{\pm}0.03mm$ n=10) in total length. 12 days after hatching, postlarvae was measured 3.77~4.67 mm ($4.27{\pm}0.33mm$) in total length, its the second pole tide of dorsal fin and the first pole tide of pelvic fin was extended longitudinally. 71 days after hatching, juvenile was measured 40.5~45.4 mm ($42.6{\pm}2.04mm$) in total length. Seven bands were observed in body, and pole tides of dorsal and pelvic fins were shortened.
