This study explores the situation of domestic production and import of dyes as well as type of dye supplier and type of dyer in the Joseon Dynasty based on an analysis of relevant documents. The findings are as follows. Many kinds of natural dyes and natural mordant were produced in the Joseon Dynasty. Some were imported from other countries when in short supply or for diplomatic reasons. As the government organization in charge of the dyes supply and demand, the Jeyonggam was cooperated with the Gongin merchants. As private merchants, there existed Hwapijeon merchants and Cheongramgye merchants. Cheongramgye merchants were both the producer and the seller of indigo sediment. There existed two types of dyers, such as government-operated dyers and private dyers. The Yeomjang (master dyers) and Yeommo (female dyers) were subjugated to government departments in the early part of Joseon Dynasty, but gradually allowed to pursue self-profit. The Yeomga was the private dye house that existed in the early period of the Joseon Dynasty. Ladies and female servants were also allowed to dye for family use or to help in livelihoods. Jeonyeomga was a branch specialized in indigo dyeing. Lastly, the Yoemgye were the merchants of dyed paper and textiles as well as dyers.

The paper deals with the applications of spectral finite element method to the dynamic analysis of framed foundations supporting high speed machines. Comparative performance of approximate dynamic stiffness methods formulated using static stiffness and lumped or consistent or average mass matrices with the exact spectral finite element for a three dimensional Euler-Bernoulli beam element is presented. The convergence of response computed using mode superposition method with the appropriate dynamic stiffness method as the number of modes increase is illustrated. Frequency proportional discretisation level required for mode superposition and approximate dynamic stiffness methods is outlined. It is reiterated that the results of exact dynamic stiffness method are invariant with reference to the discretisation level. The Eigen-frequencies of the system are evaluated using William-Wittrick algorithm and Sturm number generation in the $LDL^T$ decomposition of the real part of the dynamic stiffness matrix, as they cannot be explicitly evaluated. Major's method for dynamic analysis of machine supporting structures is modified and the plane frames are replaced with springs of exact dynamic stiffness and dynamically flexible longitudinal frames. Results of the analysis are compared with exact values. The possible simplifications that could be introduced for a typical machine induced excitation on a framed structure are illustrated and the developed program is modified to account for dynamic constraint equations with a master slave degree of freedom (DOF) option.

Purpose: The aim of this study was to explore the effects of dynamic balance training on pain, physical function, and dynamic balance in individuals with knee osteoarthritis. Methods: Fourteen patients with knee osteoarthritis participated in this study. The patients were randomly assigned to two groups: an experimental group (n=7) or a control group (n=7). All the patients took part in a lower extremity strength program for 30 min. In addition, the experimental group participated in a 30-min dynamic balance program. Both groups performed the program five times a week for 3 weeks. Outcomes, including the numeric rating scale (NRS), Western Ontario and MacMaster Universities Arthritis Index (WOMAC), and Community Balance and Mobility Scale (CB&M), were measured at baseline and after 3 weeks. Results: Both groups showed pre-to-post intervention improvements on all outcome measures (p<0.05). The experimental group showed a significant improvement in WOMAC (p = 0.00; Z = -2.82) and CB&M (p = 0.03; Z = -2.20) scores after the intervention as compared with those of the control group. Conclusion: The results revealed that dynamic balance training improved physical function, as well as balance ability, in patients with knee osteoarthritis as compared with that of a control group with no balance training.

The purpose of this study was to understand how patients experience their nurses, healing relation-ships. The 33 participants were patients who had been admitted to a general nursing unit of a university hospital in Seoul for more than one week, understood the study purpose and agreed take part, were fully conscious, able to communicate and over 20 years of age , their health was improving and they were ready for discharge. The data for this descriptive study using ground theory approach were collected by direct interviews with patients using five main questions derived from the literature and clinical experiences about their experiences of their nurses, healing relationships during hospitalization. Van Kaam’s method was used to analyse the data audio-recorded. Interpretation was enhanced consultations with two supervisors and one head nurse with a master’s degrees in nursing science, one nursing professor and one nursing docotoral candidate. Twenty - four patients said that they had formed a healing relationship with a nurse and nine said their relationship was not healing relationship. Six categories emerging from the characterizations of the healing relationships were valuable gratifying comforting trusting close and sympathetic. Descriptions of non - healing relationships were classified as none and poor. For this group of hospitalized patients nurses’ healing relationships were defined as valuable gratifying comforting trusting close as sym-Pathetic. Since the data suggest a change in the experiences during hospitalization, a gronded theory approach is recommended for further study.

This paper provides a new technique for solving the static analysis of arbitrarily shaped composite plates by using Strong Formulation Finite Element Method (SFEM). Several papers in literature by the authors have presented the proposed technique as an extension of the classic Generalized Differential Quadrature (GDQ) procedure. The present methodology joins the high accuracy of the strong formulation with the versatility of the well-known Finite Element Method (FEM). The continuity conditions among the elements is carried out by the compatibility or continuity conditions. The mapping technique is used to transform both the governing differential equations and the compatibility conditions between two adjacent sub-domains into the regular master element in the computational space. The numerical implementation of the global algebraic system obtained by the technique at issue is easy and straightforward. The main novelty of this paper is the application of the stress and strain recovery once the displacement parameters are evaluated. Computer investigations concerning a large number of composite plates have been carried out. SFEM results are compared with those presented in literature and a perfect agreement is observed.

실시간 응용 프로그램은 미디어 데이터간에 만족되어야 할 동기화 제약조건(synchronization constraints)을 가지고 있다. 멀티미디어 데이터의 가변적 전송 시연 시간을 흡수하여 피드백 제어와 재생정책에 의한 동기화 기법을 수행한다. 버퍼의 수위가 정상레벨을 유지하는가에 대한 문제는 재생률과 QoS 서비스에 중요한 영향을 주게 된다. 본 논문에서는 버퍼의 수위를 안정상태고 유지하기 위해 피트백을 위한 필터링함수를 적용하고, 재생시간을 적응적으로 적용하여 미디어의 재생 시 끊어짐이 없는 유연한 재생을 한다. 또한 버퍼의 주 미디어인 오디오 프레임의 버퍼가 상위임계레벨에 수위가 존재 할 경우는 적응적으로 재생시간을 줄이고, 하위임계레벨에 버퍼의 수위가 있을 경우는 점차적으로 재생시간을 늘리는 시스템이다.
