심박은 주위에 환경적, 신체적, 정신적 상태가 많은 영향을 끼친다. 실험에서 정서를 판단함에 있어서 안정된 상태를 만들어야 정확한 데이타를 얻을 수 있다. 사람은 하루 중 심박수가 시간 및 상태에 따라서 다르다. 그래서 심박수의 안정 상태를 만들어야 한다. 의학에서는 신체적으로 볼 때 낮아지는 심박수일수록 안정 상태이다. 하지안 사람마다 평균 심박수가 다르고 시간마다 심박수 평균이 달라진다. 그래서 심박수로는 안정 심박을 구하기가 힘들다. 심박 패턴을 추출할 때 장기 분석을 통한 검증이 정확하다. 하지만 장기 분석을 하지 않아도 피험자의 안정 상태를 유도 할 수 있다면 장기 분석을 하지 않아도 된다. 안정 심박 패턴을 유도하기 위해서 사용한 청각자극은 우리가 일반적으로 집중력과 스트레스 피로를 해소하는 MC Square와 모차르트 음악을 선정하였다. 두 개의 청각 자극이 안정된 심박을 유도 와 안정된 심박 패턴을 만들 수 있는지를 분석하여 유사점과 차이점을 비교하였다. 본 논문은 분당 심박수 변화와 심박 패턴분석으로 청각자극이 안정된 심박수를 유도하는 유의미한 결과 얻었으며 주위의 영향을 받지 않는 상태 즉, 평상심을 유도 할 수 있었다.

A video-work story analysis system based on emotional state measurement includes a content provision unit which provides story content of a video-work, a display unit which displays content provided by the content provision unit, an emotional state measurement unit which measures a tense-relaxed emotional state of a viewer viewing the displayed story content, a story pattern analysis unit which analyzes the tense-relaxed emotional state measured from the emotional state measurement unit according to a scene in the story content provided by the content provision unit, and a story pattern display unit which prints out an analysis result or displays the analysis result as an image. The emotional state measurement unit measures a tense or relaxed emotional state through one or more analyses among a brainwave analysis, a vital sign analysis, or an ocular state analysis. A writer may obtain support in an additional scenario modification work, and an investor may obtain support in making a decision through the above description. Furthermore, the video-work story analysis system and analysis method based on emotional state measurement may extract a particular pattern with respect to a change in an emotional state of a viewer, compile statistics, and analyze a correlation between a story and an emotional state.

In this paper, we propose an array pattern synthesis scheme using semidefinite programming (SDP) under array excitation power constraints. When an array pattern synthesis problem is formulated as an SDP problem, it is known that an additional rank-one constraint is generated inevitably and relaxed via semidefinite relaxation. If the solution to the relaxed SDP problem is not of rank one, then conventional SDP-based array pattern synthesis approaches fail to obtain optimal solutions because the additional rank-one constraint is not handled appropriately. To overcome this drawback, we adopted a bisection technique combined with a penalty function method. Numerical applications are presented to demonstrate the validity of the proposed scheme.

Wattle length, width, and area were measured to classify bilateral asymmetries in four lines of chickens. The lines were the S26 generation of White Leghorns selected for high (HAS) or low (LAS) response to sheep red blood cells and sublines in which selection had been relaxed for three generations (high antibody relaxed [HAR] and low antibody relaxed [LAR]). Antibody titers (AB) were greater for HAS than for HAR with both greater than for LAS and LAR which while different for males did not differ for females. The low antibody lines were heavier and reached sexual maturity at younger age than the high antibody lines. In general, wattle length, width, and area were greater in the low than high antibody lines. In 24 comparisons for bilaterality 18 exhibited fluctuating asymmetry and 6 exhibited directional asymmetry with 5 of the 6 being for wattle length. There was not a clear pattern for changes in degree of asymmetry when selection was relaxed for 3 generations. For females, the relative asymmetry (RA) of wattle area was larger ($p{\leq}0.05$) for HAR than for LAR and not different from the selected lines and relaxed lines. There were no differences among lines for RA of wattle length and width of females and wattle length, width, and area of males.

본 연구의 목적은 구순이 이완되도록 개구한 상태(relaxed lip position)에서 촬영한 측모 두부방사선사진과 일반적으로 채득하는 중심교합위에서 입술을 다문 상태(closed lip position)의 측모 두부방사선 사진에서 비순각의 변화 양상을 비교하여 안모 분석 시 relaxed lip position의 중요성을 검토하는 것이다. 전치부 반대교합을 보이는 골격성 III급 부정교합 성인환자(평균 23.3세) 60명(남자 35명, 여자 25명)을 연구대상으로 선정하였다. 구순이 이완되도록 개구한 상태에서와 중심교합 상태에서의 비순각 차이를 비교한 결과 유의성 있는 차이가 있었으며, 비순각의 변화량 사이의 유사성을 기준으로 좀 더 객관적으로 분류하여 분석하고자 군집분석을 통해 제1군(27명, 45%, 구순 이완시 비순각이 감소하는 군), 제2군(30명, 50%, 구순 이완 시 비순각이 증가하는 군), 제3군(3명, 5%, 구순 이완 시 비순각이 예외적으로 크게 증가하는 군)으로 분류하였다. 제1군에서는 상순이 전체적으로 후방 이동되며 비순각은 변화가 없거나 오히려 감소하였으며, 제2군에서는 상순이 후하방 회전되며 비순각이 증가하였다. 제3군에서는 상순이 하순과 하악전치에 의해 상방으로 압박되었다가(compression)이완되며 비순각이 크게 증가하였다. 이상의 연구 결과에서 골격성 III급 부정교합자에서 구순이 이완된 상태에 대해 중심 교합 시의 비순각의 변화가 다양한 것을 알 수 있었다. 따라서 정확한 안모분석과 수술-교정 치료 후의 연조직 심미성의 예측을 위해 기록 채득과 분석 시 이완된 구순 위치에 대한 고려가 필요하며 이러한 자세로 진단용 방사선 사진을 촬영하는 것이 필요하다고 생각되었다.

The total relaxed stress in annealing and the thermal strain/stress were obtained from the identification of the residual stress-free state using electronic speckle pattern interferometry (ESPI). The residual stress fields in case of both single and film / substrate systems were modeled using the thermo-elastic theory and the relationship between relaxed stresses and displacements. We mapped the surface residual stress fields on the indented bulk Cu and the 0.5 $\mu\textrm{m}$ Au film by ESPI. In indented Cu, the normal and shear residual stress are distributed over -1.7 GPa to 700 MPa and -800 GPa to 600 MPa respectively around the indented point and in deposited Au film on Si wafer, the tensile residual stress is uniformly distributed on the Au film from 500 MPa to 800 MPa. Also we measured the residual stress by the x-ray diffractometer (XRD) for the verification of above residual stress results by ESPI...

Recently, brick pavement were widely introduced on the pavement in rural area. A variety of vision effects can be created from patterns of brick pavement. However, in most of brick pavement works, human psychological characteristics were not concerned. The purpose of this research was to discover psychological effect on brick pavement pattern. The results of the research can be summarized as follows: 1)Psychological impression on brick pavement pattern is similar among man and woman groups. 2)Stack bond and running bond pattern have a simple, relaxed, organized, and comfortable psychological characteristics. Basket weave & stack bond pattern has a simple and organized psychological characteristic. Herringbone bond pattern has a complex, dislike and uncomfortable psychological characteristic. Pinwheel bond pattern has a highly complex psychological characteristic. Basket weave and Basket weave variation bond pattern have a common psychological characteristic. 3)Employment of brick pavement pattern on this research is not highly preferred, hence it is necessary to develop a brick pavement patterns that have human psychological characteristics be concerned.

Congenital melanocytic nevus consists of congregations of nevomelanocytes. It is found in approximately 1% of new born infants. Congenital melanocytic nevus needs to be excised before it transforms into a malignant lesion. Many strategies have been attempted for the removal and reconstruction of the nevus. Serial excision enables wound closure to be accomplished with a shorter scar than if the original lesion was elliptically excised in a single stage and reorientation of the scar closer to the relaxed skin lines. The routine utilization of an elliptical serial excision as a standard method of closure often leads to the formation of elongated scars and waste of skin. The "Cogwheel pattern" serial excision is a new technique for reducing the size of the nevus efficiently. Reducing the final scar length, distributing the tension over many directions, and having the chance of decrease in operation numbers are ultimately achieved with the use of the "Cogwheel pattern" serial excision.

Inlay is a high technique of inlaying patterns on the surface of crafts and widely used transcending time and place at various hand crafting area. Inscribed pattern technique using rare materials in the area have been used by the artisans of artistic flair and functionality and its value is also highly regarded from ancient to modern and inherits and is being developed today. Existing inlay technique, however, has not been spread out because it needs craftsman's skill based on the handcraft and inscribed materials are very rare to use. This paper aims to replace natural wood Sanggam materials for traditional furniture patterns such as Samho Jang, Ohho Jang, Seongtoenoe Moon, Gyeopgwinoe Moon and wood inlay text like Soo (Long life), Bok (Luck), Kang (Peace), Ryoung (Relaxed) and gammadion cross pattern. Gathered black, yellow and white color dyed wood using power tools can replace rare natural inlay materials through reliable and standardized supply. Dyed-gathered inlay materials can easily replace wood inlay materials, therefore, attempt to create an improved direction regarding materials and fabrication techniques in order to make traditional or contemporary artistic furniture to be produced.
