As the desires of market get various, so its demand fluctuates frequently. The only companies that flexibly meets fluctuating demands can survive in the fierce market competition. In this study, we deal with the development of jig system for manual welding processes that can cause flexible actions and uniform quality in the manufacturing shock absorber base assembly of automobile. For this we review the processes of design and development through analysis of the technology and the customer that are patents analysis, customer desires analysis, functional analysis and so on. Moreover, we review the relevant indicators for improvement of productivity that are production capacity, cycle time and error rates etc. as the technology is developed.

This study is to investigate the effects of support program satisfaction in the organizational trust and the management performance for the start-up business to suggest institutes and working-level officials with an theoretical and practical implication. For this, we performed empirical analysis, in particular we examined mediation effects of the organizational trust. We surveyed a questionnaire for 247 start-up companies of incubation center. We performed reliability and correlation analyses etc. through SPSS 23 and performed structural equation model analysis etc. through Amos 23. As a result, first, pilot product, marketing, financial account, education and consulting appeared effective effects in management performance but law did not appear effective. Second, education and consulting appeared positive by mediation of the organizational trust. This means the organizational trust factor has to be considered in support programs like education and consulting.

As carbon material is being developed the versatile one with merits of metal, non-metal, ceramic and plastic etc., it owes to the characters of light weight and strength comparing with other metal materials. Based on these characters it is applied to vehicle lightening and aerospace industry. Furthermore thermal function utilization, removal of environmental pollution material, prevention of water pollution and the area of medicine science combining into drug as well. Therefore in this study we analyze technology paradigm home and abroad for carbon material on the basis of its relative patents and consider the establishment of technology strategy for its business commercialization

쇽옵서버 피스톤로드(shock absorber piston rod)는 자동차의 충격과 진동의 흡수에 작용하는 자동차 현가장치(sus-pension equipment)부품의 일종이다. 피스톤로드는 자동차 충격흡수에 매우 밀접한 영향을 주기 때문에 제조에 있어서 고도의 정밀도와 표면 매끄러움이 요구된다. 피스톤로드의 제조공정은 선삭, 홈가공, 밀링, 건조 등 여러 공정으로 구성되는데, 여기서 품질불량에 가장 크게 영향을 주는 공정은 선삭공정(lathing

This study was carried out to estimate the daily intake of lead and the relationship among dietary intake, serum level, and urinary excretion of calcium in 30 healthy adults living in rural area of Korea(12 males and 18 females). Analyses for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hour urine collection, and venous blood sampling. The results were as follows : The mean daily intake of energy was 2, 176.3㎉ and l, 613.9㎉ in males and females of 20∼49years, and l, 914.8㎉ and l, 517.9㎉ in males and females of 50∼59years, respectively. The ratio of carbohydrate: fat: protein was 73.4:13.6:13.0 in males and 76.4:10.3:13.3 in females. The mean daily intake of lead was 277.2㎍ in males and 192.0㎍ in females. The mean daily intake, serum level, and urinary excretion of calcium were 491.1㎎, 8.9㎎/㎗, and 80.7㎎ in males and 426.7㎎, 8.8㎎/㎗, and 80.3㎎ in females, respectively. No significant correlation was found between the daily lead intake and the dietary intake, serum level, and urinary excretion of calcium. It was concluded that the daily lead intake was lower than the acceptable daily lead intake of FAO/WHO but a little higher than that of other investigations. And the daily lead intake was not level that relate to calcium status seriously.

The effects of six kinds of phosphate complex on the water holding capacity (W.H.C) and protein solubility of hair tail, yellow tail runner and dried pollack meat paste were investigated and animal meat(pork, chicken and hare meat complex). The formulation of six kind of phosphate complex employed to this experiment were made by mixing several phosphate such as sodium polyphosphate, sodium pyrophosphate, sodium acid pyrophosphate, potassim pyrophosphate, sodium ultra-meta-phosphate, sodium-tetra-phosphate and monoglyceride at different mixture ratio. Among the six kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium polyphosphate 40%, sodium pyrophosphate 30%, sodium tetra mata phosphate 10%, sodium ultra meta phosphate 10% was most effective on enchanging the W. H. C. and protein solubility of hair tail, yellow tail runner dried pollack meat past and in case of pork, chicken and hare meat paste. Phosphate C complex which was formulated by mixing sodium polyphosphate 50%, sodium pyrophosphate 30%, sodium tetra meta phosphate 10%, potassium pyrophosphate 10%, was more effective them other phosphate complex, and thier optimum addition level was 0.5% respectively in weight of fish meat paste. Texture characterstics such as hanrdness, cohesiveness and springiness value of Kamaboko(fish meat and pork, chicken, hare meat complex past meat product) were evaluted as best when 0.5% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 20 minutes at 120℃.

This experiment was carried out to investigate the changes in quality of pork organs such as the meat of large intestine, small intestine and liver during frozen storage at -18±1℃. The result obtained were as follows ; 1. The moisture contents in the meat of large intestine, small intestine and liver was 61.1%, 65.1% and 71.3% and the content of crude fat was 27.1%, 21.5% and 5.0% respectively. 2. Weight loss increased in the course of storage period, and liver showed the least weight loss in them. 3. Total lipid in the meat of large intestine, small intestine and liver was 24.4%, 19.2% and 4.3% respectively, and which decreased gradually in the course of storage period. 4. The content of volatile basic nitrogen in raw meat was 20㎎% within and without before storage treatment, and that of the value was 24.2㎎% within after 3 weeks storage.
