This paper investigates the structural responses of axially restrained steel beams under fire conditions by a nonlinear finite element method. The axial restraint is represented by a linear elastic spring. Different parameters which include beam slenderness ratio, external load level and axial restraint ratio are investigated. The process of forming a mid-span plastic hinge at the mid-span under a rising temperature is studied. In line with forming a fully plastic hinge at mid-span, the response of a restrained beam under rising temperature can be divided into three stages, viz. no plastic hinge, hinge forming and rotating, and catenary action stage. During catenary action stage, the axial restraint pulls the heated beam and prevents it from failing. This study introduces definitions of beam limiting temperature $T_{lim}$, catenary temperature $T_{ctn}$ and warning time $t_{wn}$. Influences of slenderness ratio, load level and axial restraint ratio on $T_{lim}$, $T_{ctn}$ and $t_{wn}$ are examined.

In general, a DC solenoid valve is evaluated by the performances such as the attraction force at maximum and minimum strokes, temperature rising, power consumption and time of action. The importance of each performance may be different according to the specific application purpose. When the temperature rising and power consumption are fixed, however, the performance of DC solenoid valve is usually evaluated by the attraction force at maximum and minimum strokes and time of action. In this paper, the shape of the pole face of plunger and core is optimized to increase the attraction force at maximum stroke, and thereby to minimize the time of action. For the shape optimization, (1+1) evolution strategy is incorporated with the response surface method(RSM) and finite element method(FEM).

This study was described the movement patterns when rising from supine to erect stance. Two hundred eighty seven subjects, ranging in age from 6 year to 28 were filmed while rising from a supine position. Movement Patterns were classified using categorical descriptions of the action of three body regions-the upper and lower extremity, head-trunk region. This study was designed to determine whether within the rising task the movement patterns of different regions of the body vary with age level and sex. The incidence of each movement pattern was calculated and graphed with respect to age level and sex. The most common form of rising for subject in the 6, 7 year mate group usually involved push and reach pattern with upper extremity, half kneel pattern with lower extremity, partial rotation pattern with head-trunk. In the 6, 7 year female group usually involved symmetrical push pattern with upper extremity, symmetrical squat with balance step pattern with lower extremity, symmetrical interrupted by rotation pattern with head - trunk. In the teenage and twenties both sex group usually involved symmetrical push pattern with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern with head-trunk.

This study wan described the movement patterns when rising from supine to erect stance in the third through eighth decades. Two hundred fifty six subjects, ranging in age from 30 year to 89 were filmed while rising from a supine position. Movement patterns were classified using categorical descriptions of the action of the upper and lower extremity, head-trunk region. This study was designed to determine whether within the rising task the movement patterns of different regions of the body vary with age level and sex, to describe time by subjects to perform this task. The incidence of each movement pattern was calculated and graphed wi th respect to age level and sex. Erect standing time was increased by age increasing in beth sex group. The most common form of rising for subject in the third through fifth decades both sex usually involved symmeytrical push with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern wi th head-trunk and symmetrical push to push and reach pattern with upper extremity, symmetri cal squat pattern with lower extremity. partial rotation with head-trunk. In the sixth through eighth decades usually involved symmetrical push to push and reach pattern with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern with head-trunk in both sex group.

Safety operational envelope (SOE) is the area which guarantees the safety of a submarine from the accident such as jamming and flooding. The maximum safe depth is set to prevent the damage to the hull from increasing water pressure with depth. A minimum safety depth is set to prevent a submarine from the exposure above the free surface and collision against surface ship. The prediction method for the SOE in the design phase is needed to operate the submarine safely. In this paper, the modeling and calculation methods of the SOE are introduced. Main ballast tank blowing modeling and propeller force modeling are conducted to simulate the accidents and the recovery process. The SOEs are established based on the crash stop and emergency rising maneuver simulation. From the simulation results, it can be known that the emergency rising maneuver is more effective recovery action than the crash stop.

The purpose of this study were to describe the movement pattern used to rise from supine to erect stance and to evaluate the influence gender might have on the movement patterns used for rising. Fifty males and fifty-three females, mean 14 years of age, performed the rising task while being videotaped. Movement patterns were classified using categorical descriptions of the action of three body regions; the upper extremities, lower extremities, and head-trunk region. The most common pattern of males and females were symmetrical push(upper extremity), symmetrical(head-trunk) and symmetrical squat(lower extremity). In the upper extremity component, a symmetrical reach to push pattern was new category. Eighteen of males and twenty-one of females different movement pattern combinations were observed. Results indicate physical therapists should consider the patient's age and gender.

뮤지컬은 노래와 춤이 극의 플롯 전개에 긴밀하게 짜 맞추어진 연극으로 노래와 춤은 특정한 상황과 일련의 사건을 전개한다. 특히 노래는 등장인물이 지향하는 목표와 액션을 구체적으로 담아내면서 극의 중대한 변화를 일으키고 정서 환기와 증폭의 기능을 수행한다. 본 논문은 플롯 전개의 기능을 맡는 노래에 초점을 맞추어 '무대 위의 액션과 이야기를 구현하는 노래'를 '액션송'이라는 용어로 정의하고 그 역할과 중요성을 부각하고자 한다. '액션송'은 통합 뮤지컬의 극의 초반에 삽입되는 '캐릭터송'으로 부여받은 개인의 욕망이나 행동의 동기가 액션의 중심 사건인 갈등을 제공하면서 등장인물이 자신의 목표를 달성하기 위한 투쟁하는 과정을 다룬 노래이다. 즉, '액션송'은 무대 위의 액션을 가사가 있는 노래로 전달하여 음악과 서사를 유기적으로 결합한 노래를 뜻한다. 또한, 플롯을 앞으로 진전시키는(which move the plot forward) 노래이며 플롯 전개의 재료가 되는 일련의 사건 혹은 장면의 액션(Action)을 담은 노래이다. 본 논문은 우리에게 잘 알려지지 않은 '액션송'의 개념을 정리하고 연구의 토대를 마련하기 위한 것으로 뮤지컬 <공포의 꽃가게>를 대상으로 대본과 음악분석을 통해 '액션송'의 개념과 기능과 효용성을 알아보았다. 그 결과 액션송은 갈등으로 인한 긴장감을 축적하고 증폭시켜 극을 고조하게 만들며 관객의 감정몰입을 유도한다. 동시에 액션송 이후에 다음 장면에 대한 기대감을 상승시키면서 극의 재미와 흥미를 배가시키고 단일한 액션을 중심으로 한 극의 전개는 극의 내용을 선명하고 뚜렷하게 파악할 수 있게 만든다.

As material needs have been increasing with recent economic growth, it is a current tendency that the magnitude of load applied to structure has been rising. With improved technique of product materials, steel and concrete have been stranger than ever so the danger of fatigue damage increases as permanent action of repeated loads. In case of deformed steel bars widely used in reinforced concrete structure, when they are product in factory, there will exist same parts connecting the steels. Such connections are easy to be weakened by permanent action of repeated loads. It is a real condition in Korea that there is lack of research of it. As a result of estimating fatigue characteristic of Pressure Welded joints with the steels that are oftenly used and producted in domestic it is showed that there are no remarkable difference in fatigue strength. Because there is no detail which is refered in Civil Specification, this paper will be the basic data being added in later Specification.
