본 연구는 '언론의 자유' 권리와 '유사언론 행위'라는 주장에 의거한 온라인 신문 규제 주장 간의 충돌 현상을 법적 윤리적 쟁점에 따라 세분화하였다. 이를 위해 2012년부터 2017년까지 온라인 매체 상에 존재하는 현대식 마녀사냥 현상과 관련한 사건들을 조사해 유사언론 행위, 사이비언론 행위에 대한 규제 주장의 근거와 연관 지어 해석하였다. 또한 윤리적 논쟁이 되는 반대 의견으로 언론의 자유와 책임, 이에 반하는 명예권과 프라이버시 권리 등이 충돌할 경우 우선시 되는 권리에 대한 과거 연구들을 종합하고, 5인 이하 소규모 온라인 신문사의 언론의 자유 권리에 대한 최근의 판례 등을 정리하였다. 각 주장의 근거로써 실질 현상으로 나타난 사례들과 이에 대립하는 의견들의 논거 비교를 통해 현재 논쟁 중인 온라인 매체상의 뉴스 행위의 법적 윤리적 문제에 대해 종합적으로 고찰하였다.

The differential gear system is a device designed to distribute the driving force of both vehicle wheels and control the rotational speed when the vehicle turns on a curve. The differential device consists of a differential gear case, a ring gear, and a pressure ring. A differential pinion gear and side gear are mounted on the differential pinion shaft inside the differential gear case. In this study, a pin press-fitting device that mounts the pinier gear and side gear to the differential pinion shaft in the differential gear case was designed, and a jig device for pin press-fitting using servo press was developed. In addition, by precisely measuring the pin press-in load and press-in distance according to the pin hole diameter of the differential gear shaft, the optimization of the pin pressin process was established.

Purpose: The purpose of this study was to evaluate the effects of hand moxa and hand press pellet on blood pressure, blood lipids and blood cell components in elderly women. Methods: This study was conducted as a quasi-experiment with none equivalent control group pre-post test design. The participants were elders who had essential hypertension. There were 18 members in the experimental group and 20 members in the control group. The experimental group received hand moxibustion and hand press pellet 3 times a week for 12 weeks. The results were analyzed using $x^2$ test, t-test, Fisher's exact test and repeated measures ANOVA with the SPSS/WIN program. Results: There were significant decreases in blood pressure in the experimental group compared to the control group. No significant difference was observed in total triglyceride, LDL cholesterol and HDL cholesterol between the two groups. Differences in hemoglobin and hematocrit were not significant either. However, there were significant increases in RBC in the experimental group after the intervention. Conclusion: The results suggest that combined hand therapy contributes to the decrease of blood pressure among the elderly with hypertension. Therefore combined hand therapy is recommended as a complementary nursing intervention strategy for the elderly with essential hypertension.

일반적인 프레스햄을 대조구로 설정하고, 인삼분말 첨가수준을 달리하여 4 처리구로 설정하였으며, 등심 원료육 중량에 대하여 처리구별로 0.5%(처리구 1), 1%(처리구 2), 1.5%(처리구 3), 2%(처리구 4)를 첨가하여 프레스햄을 제조한 후 진공포장하여 냉장온도(4℃)에서 1, 7, 14, 21 및 28일간 저장하면서 전단가, 관능적 특성분석, 지방산화 및 지방산 조성변화 등을 조사하여 품질 특성을 규명하고자 실시하였다. 전단가는 대조구와 인삼분말 첨가구간에 유의적인 차이가 없었으며, 모든 처리구가 저장기간이 경과함에 따라 감소하였다. 관능적 특성 중 육색은 인삼분말 첨가구에 비하여 대조구가 유의적으로 높았으며, 인삼 향은 인삼분말 첨가수준이 증가할수록 유의적으로 증가하였으며, 전체적인 기호성은 대조구에 비하여 인삼분말 첨가구가 다소 높은 경향이었다. 모든 항목에서 저장기간이 경과하여도 뚜렷한 경향은 없었다. 지방산화는 인삼분말 첨가구가 대조구에 비하여 유의적으로 낮았으며(P<0.05), 지방산화는 모든 처리구가 저장기간이 경과함에 따라 유의적으로 증가하였다(P<0.05). 지방산 조성은 대조구와 인삼분말 첨가구간에 유의적인 차이가 없었으며, 저장기간의 경과에 따른 변화는 없었다.이상의 결과 프레스햄 제조시 인삼분말 첨가가 전단가, 관능적 평가 및 지방산 조성에 영향을 미치지 않으며, 제품의 저장기간을 연장 및 사포닌 성분이 축적된 고급 육제품 생산이 가능하다고 사료된다.

In this paper, a new block iterative algorithm is presented by using the special feature of the continuous Riccati equation in the optimal shape control. Because the real-time control require that the CPU time should be as short as possible, an appropriate modal control algorithm is sought. The computing cost is less than the one of the all state feedback control. A numerical example is given to illustrate the algorithm.

Proofing is one of the inspection operations of printing and can be considered a process control step. The three main kinds of proofs are press proofs, photomechanical proofs, and digital proofs. Photomechanical and digital proofs are also generally refered to as "off-press" proofs. Off-press color proofs are more economical than press proofs. Digital proofs offer fast production time along with a much lower cost per page. Hard-copy digital proofs can be output using thermal transfer printers, ink jet printers, and color laser copiers, as well as dye sublimation and electrophotographic technology. Ink jet method is commonly using because of the reasonal price. But ink jet system is difficult to reproduce an exact color proof. This research was carried out for the purpose of optimization of ink jet color proofing, using two kinds of ink jet printers with 6 colors (C, M, Y, K, mC, mM) and 4 colors (C, M, Y, K) system.

A servo gun welding system having a AC servo motor and a PC control system is presented for the improvement of quality control in the spot welding. The spot welding process is composed of the press stage, the weld stage, and the hold stage. The changes of gun press forces according to three stages in the spot welding process are controlled and measured through the load cell in order to know the influence on the welding quality. The relation between the measured force changes according to three stages and welding qualities is also implemented on the multilayer perceptrons, one of supervised learning method of neural network, which are powerful for realization of complex mapping characteristics. The estimated results and ...
