The paper aims to investigate the asymmetric long-run and short-run relationships between inflation and remittance outflows in the Kingdom of Saudi Arabia (hereafter KSA) over the period 1971-2019 by using the Nonlinear Autoregressive Distributed Lag (NARDL) model. The statistical tests have supported the validity and stability of the model. The Wald F-test statistics confirm the existence of a long-run equilibrium relationship among the model variables; remittance outflows, positive (negative) shocks in inflation rates, investment, real GDP, and trade openness. Moreover, the empirical results confirm the existence of an asymmetric effect of the inflation rate on remittance outflows. The response of foreign workers to an increase in inflation rates differs from their response to a decrease in inflation rates. However, this asymmetric relationship between the increases/decreases in inflation and remittance outflows is significantly weak. The weakness of this relationship is due to the high marginal remittance propensity of migrant workers, which is explained by the low consumption propensity of foreign workers and their ability to adjust to the high cost of living due to inflation and the imposition of accompanying fees. Finally, the change in the inflation rate is not among the main factors influencing foreign remittance decisions in Saudi Arabia.

상호의존성은 유통경로상에 존재하는 기본적 특성으로서 오랫동안 유통분야에서 관련연구들이 활발하게 진행되어 왔다. 특히 갈등은 유통경로상의 거래관계를 특징짓는 주요 특성으로서 상호의존성과 갈등 간 관계를 규명하는 것은 의미하는 바가 크다. 그러나 사회학 분야에서는 상호의존성과 갈등 간 관계를 설명하는 상반된 이론이 존재하며, 마케팅 분야에서도 상호의존성과 갈등 간 관계에 대해서 상반된 연구결과가 제시되었다. 이에 본 연구에서는 상호의존성과 갈등 간 관계에 대해 대립된 설명을 하고 있는 쌍무적 억제이론과 갈등나선형이론 등의 사회학 이론을 활용하여 붙균형적 상호의존성과 갈등간 비선형적 관계를 제안하고, 이를 위해 소방관련 전문공사업체들과 공급업체들로부터 설문데이타를 수집하여 불균형적 상호의존성과 갈등간 역U형태의 관계가 있음을 증명하고자 한다. 분석결과 구매업체집단과 공급업체집단 모두에서 상호의존성의 총합이 높을 때 불균형적 상호의전성과 갈등간 비선형적 관계가 통제적으로 유의미하게 도출되었다. 마지막으로 몇 가지 학문적 시사점들과 한계점 및 향후 연구 과제를 제시하였다.

The thick plate produced by rolling process is used as the basic members of a ship structure. In this paper, we present a setup model to control the asymmetric factors causing plate bending in the upper or lower direction during rolling. A series of finite element analysis are conducted to predict the relationship between various asymmetric factors and plate bending. The setup model is developed by regressing the relationship to the linear equations with several non-dimensional parameters. The setup model is verified by a pilot rolling test and applied to actual rolling conditions. Results show that the model is substantial to predict the asymmetric deformation in the plate rolling process.

본 연구는 교육서비스 프랜차이즈 제휴 운영에 있어 효과적인 자원배분을 위한 전략적 대안을 제시하고자 프랜차이즈 본사와 가맹원간 관계특성이 관계품질과 제휴의 관계적 성과에 미치는 프로세스를 제안하였다. 모델의 검증을 위해 교육업에 종사하는 가맹원을 대상으로 설문조사를 실시하였으며, 수거된 설문지 중 200개의 설문지를 분석에 사용하였다. 분석결과, 대칭적관계보다는 비대칭적관계에 의해 관계품질의 수준이 더욱 영향을 받는 것으로 나타났다. 특히 교육서비스의 경우 프랜차이즈 본사와 가맹점간 거래특유투자의 불균형이 관계품질을 저하하는데 가장 큰 영향력을 미치는 것으로 나타났다. 또한 외국계 프랜차이즈와 비교하였을 때 국내 로컬 프랜차이즈는 외국계 프랜차이즈보다 역할과 책임의 불균형이 크고, 가맹점들이 기회주의행동을 할 가능성이 높은 것으로 나타났다.

The principal objective of this study was to categorize service attributes on the basis of the asymmetric and non-linear relationship existing between service attributes and customer satisfaction. Researchers generally assume that service attribute performances and customer satisfaction are both symmetrical and linear. That is to say, improvements in attribute performance will inevitably result in increased customer satisfaction. However, this is not always the case. Certain attributes have been shown not to create satisfaction even when improved, and others do not create dissatisfaction even when their performance ratings become negative. Understanding this relationship is crucial not only to researchers, but also to service managers. Service managers can arrange their priorities with regard to which attributes must be improved or promoted first, in an environment of limited technical, financial, and human resources. Many studies into this asymmetric and non-linear relationship have recently been conducted, beginning with Herzberg's motivation-hygiene theory (1976) and the disconfirmation theory, which was eventually developed into Kano's model (1984). This study attempted to determine the impact level of service attributes on incidents of satisfaction or dissatisfaction. It used 30 service attributes generated by Park (2008) in the CIT research into family restaurants. The data were collected from 600 participants, 300 incidences of satisfaction and 300 incidents of dissatisfaction, via an online survey. The t-test was used to confirm the difference between the satisfaction group's and dissatisfaction group's attributes. 11 attributes were found to be significant at a level of p>0.05. This indicates that the 11 attributes exerted different impacts on satisfaction and dissatisfaction, which confirmed the asymmetric and non-linear relationship. 14 attributes were categorized into the core service, 1 attribute into the quality service, 7 attributes into the basic service, and 8 attributes into the neutral service. Strategic customer service management was recommended for the 'A' family restaurant as an example, on the basis of the asymmetric and non-linear relationship and the characteristics of the four service factors.

This paper presents an experimental investigation of asymmetric impact effects on hydroelastic responses. A 1:64 scaled segmented ship model with U-shape open cross-section backbone was newly designed to meet elastic similarity conditions of vertical, horizontal and torsional stiffness simultaneously. Different wave heading angles and wavelengths were adopted in regular wave test. In head wave condition, parametric rolling phenomena happened along with asymmetric slamming forces, the relationship between them was disclosed at first time. The impact forces on starboard and port sides showed alternating asymmetric periodic changes. In oblique wave condition, nonlinear springing and whipping responses were found. Since slamming phenomena occurred, high-frequency bending moments became an important part in total bending moments and whipping responses were found in small wavelength. The wavelength and head angle are varied to elucidate the relationship of springing/whipping loads and asymmetric impact. The distributions of peaks of horizontal and torsional loads show highly asymmetric property.

본 연구는 해운산업의 경기를 나타내는 BDI와 벙커가격의 관계를 비대칭 공적분 모형을 사용하여 분석하였다. 기존연구는 선형의 공적분 모형을 사용하여 BDI와 국제유가의 관계를 분석하였으나, 본 연구는 기존연구들에서 드러난 BDI와 유가의 상승기와 하락기의 비대칭적인 특징을 적절히 포착할 수 있는 비대칭 모형을 사용하여 분석하였다. 그 결과 기존연구에서 제시된 선형모형에 근거한 분석은 두 변수간의 장기균형 관계가 존재하지 않는 것으로 나타난 반면 본 연구에서 제시한 비대칭 모형을 통해 장기균형 관계가 존재하는 것으로 나타났다. 특히, BDI가 벙커가격에 영향을 미치고 있음이 확인되었으므로 두 변수간의 장기균형 관계는 비대칭 모형을 고려하는 것이 적절한 것으로 판단된다.

The study aims to investigate the pattern of relationships such as symmetric or asymmetric, between exchange rate and foreign direct investment in Bangladesh by applying Autoregressive Distributed Lagged (ARDL) and nonlinear ARDL. In this study, we employed quarterly data for the period of 1974Q1 to 2016Q4. Data were collected and aggregated from various sources namely, Bangladesh Economic Review published by Ministry of Finance and statistical yearbook published by Bangladesh Bureau of Statistics and an annual report published by Bangladesh Bank. The relationship between exchange rate and FDI inflows attract immense interest in the recent periods, especially for developing countries' perspective. The results of the study ascertain the long run relationship between FDI, exchange rate, monetary policy, and fiscal policy. Considering the asymmetric assumption, the findings from NARDL confirm the existence of a long-run asymmetric relationship in the empirical equation. In the long run, it is observed that positive change that is the appreciation of exchange rate against USD decrease FDI inflows and negative shocks results in grater inflows of FDI, however, the positive shocks produce higher intensity that negative shocks in Exchange rate. For directional causality, the coefficients of error correction term confirm long-run causality, in particular, bidirectional causality unveiled between FDI and exchange rate.

선박 건조를 위한 기본 자재인 후판은 압연공정을 통해 생산된다. 본 논문에서는 후판압연 중에 발생하는 폭방향 휨을 일으키는 비대칭 요인들을 제어할 수 있는 설정모델을 제시한다. 일련의 삼차원 유한요소해석을 통해서 휨과 비대칭 요인 사이의 관계를 예측한다. 그 관계를 무차원 변수로 이루어진 선형 방정식으로 수식화 시킴으로써 설정모델을 도출한다. 소재 폭방향으로 두께 편차와 온도차이가 있는 경우에 대해서 파이롯트 압연 시험으로 통해서 설정모델의 정도를 검증한다. 본 모델에 의해 예측된 휨 곡률이 각각의 비대칭 요인들에 의해 측정된 휨 곡률과 상당히 일치하는 결과를 보여 주었다.
