This study discusses a contract to promote collection and recycling of used products in a green supply chain (GSC). A collection incentive contract is combined with a reward-penalty contract. The collection incentive contract for used products is made between a retailer and a manufacturer. The reward-penalty contract for recycling used products is made between a manufacturer and an external institution. A retailer pays an incentive for collecting used products from customers and delivers them to a manufacturer with a product order quantity under uncertainty in product demand. A manufacturer remanufactures products using recyclable parts with acceptable quality levels and covers a part of the retailer's incentive from the recycled parts by sharing the reward from an external institution. Product demand information is assumed as (i) the distribution is known (ii) mean and variance are known. Besides, the optimal decisions for product quantity, collection incentive of used products and lower limit of quality level for recyclable parts under decentralized integrated GSCs. The analysis numerically investigates how (1) contract for recycling activity, (ii) product demand information and (iii) quality of recyclable parts affect the optimal operation for each GSC. Supply chain coordination to shift IGSC is discussed by adopting Nash Bargaining solution.

In the present article, the vibration response of a geometrically imperfect bi-directional functionally graded plate (2D-FGP) with geometric discontinuities and micro-structural defects (porosities) has been investigated. A porosity model has been developed to incorporate the effective material properties of the bi-directional FGP which varies in two directions i.e. along the axial and transverse direction. The geometric discontinuity is also introduced in the plate in the form of a circular cut-out at the center of the plate. The structural kinematic formulation is based on the non-polynomial trigonometric higher-order shear deformation theory (HSDT). Finite element formulation is done using C° continuous Lagrangian quadrilateral four-noded element with seven degrees of freedom per node. The equations of motion have been derived using a variational approach. Convergence and validation studies have been documented to confirm the accuracy and efficiency of the present formulation. A detailed investigation study has been done to evaluate the influence of the circular cut-out, geometric imperfection, porosity inclusions, partial supports, volume fraction indexes (along with the thickness and length), and geometrical configurations on the vibration response of 2D-FGP. It is concluded that after a particular cut-out dimension, the vibration response of the 2D FGP exhibits non-monotonic behavior.

Delayed hydride cracking (DHC) is an important failure mechanism for Zircaloy tubes in the demanding environment of nuclear reactors. The threshold stress intensity factor, $K_{IH}$, and critical hydride length, $l_C$, are important parameters to evaluate DHC. Theoretical models of them are developed for Zircaloy tubes undergoing non-homogenous temperature loading, with new stress distributions ahead of the crack tip and thermal stresses involved. A new stress distribution in the plastic zone ahead of the crack tip is proposed according to the fracture mechanics theory of second-order estimate of plastic zone size. The developed models with fewer fitting parameters are validated with the experimental results for $K_{IH}$ and $l_C$. The research results for radial cracking cases indicate that a better agreement for $K_{IH}$ can be achieved; the negative axial thermal stresses can lessen $K_{IH}$ and enlarge the critical hydride length, so its effect should be considered in the safety evaluation and constraint design for fuel rods; the critical hydride length $l_C$ changes slightly in a certain range of stress intensity factors, which interprets the phenomenon that the DHC velocity varies slowly in the steady crack growth stage. Besides, the sensitivity analysis of model parameters demonstrates that an increase in yield strength of zircaloy will result in a decrease in the critical hydride length $l_C$, and $K_{IH}$ will firstly decrease and then have a trend to increase with the yield strength of Zircaloy; higher fracture strength of hydrided zircaloy will lead to very high values of threshold stress intensity factor and critical hydride length at higher temperatures, which might be the main mechanism of crack arrest for some Zircaloy materials.

사회과학에서 현상 형태로서 제도에 대한 개념연구는 다양한 이론적 접근방법을 통해 지난 수년간 집중적으로 논의되어 왔다. 그러나 커뮤니케이션학에서는 이러한 논의가 이루어지지 않았다. 이 논문에서는 조직사회학적 신제도주의 이론을 활용, 커뮤니케이션학 분야에서 제도로서 미디어에 대한 이론논의를 시도했다. 본 연구는 사회 체계로서 미디어가 조직과 행자들에게 어떠한 영향을 행사하는지 규명하는데서 출발했다. 제도로서 미디어는 하나의 독자적인 체계로서 첫째로 규범적 당위를 제공하고, 둘째로 이러한 규범적 당위가 관철될 수 있도록 강제화하며, 셋째로 규범이 행위자에 의해서 실천되어, 넷째로 이 실천과정에서 행위자들은 제도를 인지, 우선적 선택사항을 찾아내어, 구조를 변화시킬 수 있는 영향력을 행사하게 된다. 조직은 이러한 역동적인 규범 운용에 따라 유지되는데, 이는 규범을 통해 조직의 합법성을 인정받고, 조직유지를 위한 지지를 얻을 수 있기 때문이다. 제도로서 미디어는 조직에 일정한 영향력을 행사하지만, 동시에 조직과 미디어에 종사하는 행위자로로부터 이중의 압박을 받게 된다. 이는 미디어가 조직에서 독립적으로 영향력을 행사할 수는 없고, 단지 행위자들이 조직의 수많은 갈등과정에서 생성되는 현상들을 인지하고, 이를 해석하여 중계할 뿐임을 의미한다.

Objective : The objective of this study is to verify the characteristics of acupuncture methods of Joseon Dynasty by looking into the relationship between five viscera diagnosis and acupuncture methods. Material & Method : In the process, I've reviewed the relationship between meridian/exterior and viscera/bowels, along with a thorough comparison of the academic tendency in acupuncture of Ming-China, Qing-China and Joseon. Result & Conclusion : The two fields of meridian and exterior, and viscera and bowels had been theoretically merged, and based upon that, foundation methods applying the five viscera diagnosis were designed. Joseon acupuncture exceeded the existing concept of viscera which simply related itself to the exterior meridian and exterior by integrating the concepts from the visceral manifestation theory. With this, large proportions of medicine related to the visceral manifestation theory were invited into acupuncture, expanding therapeutic boundaries for acupuncture treatment. A historical review on medical texts starts from the Hyangyakjipseongbang("鄕藥集成方") which familiarized the public with mainstream acupuncture knowledge up until the Song dynasty, followed by Uibangyuchwi("醫方類聚"), which sparked up interest on the acupuncture methods based on viscera and bowels. Donguibogam("東醫寶鑑") organized the medical theories up until then, building a foundation upon which viscera/bowel-based acupuncture was able to develop further. In Chimgugyeongheombang("鍼灸經驗方"), viscera/bowel-based acupuncture methods started to blossom, integrating the meridian and exterior theory with the viscera manifestation theory, which in turn provided various methods through five viscera diagnosis. In the Saamdoin acupuncture method(舍岩道人鍼法), diagnostic criteria moved on to the five viscera diagnosis, and new methods resulting from the inter-complimentary and inter-prohibiting relationships between the five phases were introduced, opening a new world of acupuncture.

Purpose of this study was determining predictor variables of Korean nurses' intention to educate clients and their significant others using the theory of planned behavior (TPB). Nurses working in health institutions (N=221) were conveniently selected from 2 RN-BSN programs and 2 hospitals in Seoul and Kyunggi-Do. A packet of questionnaires was developed according to the guidelines of the TPB. Multiple regression and Pearson product coefficients were used to analyze the data. Korean nurses showed positive intention to education their patients. They also showed positive attitude toward the patients education while perceived strong social pressure of teaching the patients. Attitude, subjective norms and perceived behavioral control were the predictors of the intention as the theory proposed. Especially the perceived behavioral control was the best predictors among them. Time to prepare themselves for the patient education; high self-esteem as a teacher; a perception that patients want nurses as a resource person; and the quality of information that nurse perceived they had were the predictors among the perceived behavioral control variables. Three recommendation were identified for the effective patient education. Nurses should be prepared to teach patients in their nursing school so that they have self-esteem as a competent teacher. The professional patient educators who are well-prepared for educating patients and their family are strongly recommended. Finally, development of a patient education center in the health institution were also recommended for its quality control.

This study aimed to understand the relationships among the institutional pressure and the level of compliance and corporate value. The research focuses on four main variables, which are regulatory pressure, normative pressure, and cultural-cognitive pressure as the institutional pressure, and the CSR score as the level of the firm's compliance. We examined the impact of the institutional pressure on the firm's compliance-level, together with the effect of compliance level on the corporate value. We analyzed the 3,792 CSR data listed in China's A market and 31 province and city-level data from China. Results showed that institutional pressure had a positive influence on the firm's compliance level. The corporate value was greater with a high compliance level when the institutional pressure was high. The firm's compliance level negatively influenced corporate value when the institutional pressure was low. This study took into account a level of institutional pressures in three dimensions when investigating the effect of CSR compliance level on the corporate value. Thus, this study has a unique academic contribution by demonstrating that CSR activities can have a positive or negative effect depending on the institutional environment for each firm. The findings of this study also provide valuable insights to industry practitioners by suggesting the importance of considering the institution-specific condition when deciding to comply with the institutional pressure.
