This study optimized the finely ground meat ball analogue formulation by a series of experiments. Replacing isolated soy protein (ISP) to isolated mung bean protein (IMP) in total 27% protein caused an increase in hardness while adhesiveness, springiness, and chewiness were decreased (p<0.05), and the best ISP to IMP ratio was 10:17. When protein content was changed from 19% (w/w) to 31% (w/w) with the best ISP:IMP ratio, adhesiveness was increased with decreasing protein content, but all texture profiles were greatly decreased comparing to control (p<0.05). To modify texture of plant meat ball, potato starch (PS), κ-carrageenan (KC), methyl cellulose (MC), konjac (KJ), and potato protein (PP) were applied in formulation. Finally, KJ and MC were combined with and without PP in formulation. As a result, 0.5% KJ+MC+PP and 1% KJ+MC were best formulation for plant meat ball, nevertheless, highly harder texture than control must be regulated which warranted further exploration.

This study evaluated the qualitative properties of Buchimgaru supplemented with JAP (Jerusalem Artichoke Powder). In Buchimgaru, JAP and wheat flour were mixed in ratios of 1:9 (10% JAP), 2:8 (20% JAP), and 3:7 (30% JAP). The values for texture profiles (hardness, chewiness, springiness, and cohesiveness) decreased when JAP was added to Buchimgae formulations. The fructan contents of Buchimgaru supplemented with 0, 10, 20, and 30% JAP were 1.52, 6.39, 10.50, and 13.71%, respectively. The total polyphenol content of Buchimgaru supplemented with JAP was significantly higher than Buchimgaru without JAP. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of Buchimgaru supplemented with 30% JAP was approximately 11 times greater than Buchimgaru without JAP. In the sensory evaluation (color, flavor, overall preference), Buchimgae supplemented with JAP showed higher sensory values than Buchimgae without JAP.

Under the new normal, the China's economy growth has changed rapid growth to moderate growth since 2007. With new paradigm, China is facing an abnormally severe employment situation. Also the financial expenditure is an important macro adjustment method. The research analyzes both implications of financial expenditures to employment in China, and the trend of implication in different regions. The research was conducted by 2SLS method using the panel data of 31 Chinese local governments(provinces, cities, and autonomous districts) during 1998 to 2015. The main findings are as follows. In the new normal model(2008-2015), the financial expenditure to urban employment have higher effect than total employment. Also, higher income region have more positive effect than lower income region. Medical, technology expenditure have positive effect to total employment, social security, education expenditure have positive effect to urban employment. In the total model(1998-2015) have similar results with new normal model, but the elasticity is more higher than total model. Ultimately, it can be seen that the efficiency of financial expenditure is lower than new normal model. The government should increase the proportion of expenditure in fields of social security, education, medical, technology, and improve the expenditure structure. So as to promote the effect of financial expenditure to employment in new normal economy.

The influence of heat-moisture treatment (HMT) and substitution of rice flour containing different amylose contents on the quality characteristics of rice noodles was investigated. HMT was applied to rice flours with 21% moisture content at 100 and 105$^{\circ}C$ for 30 min. Three rice cultivars were used, including high amylose of Goami (GM) and intermediate amylose of Choochung (CC) as domestic rice flours and imported rice of Taeguk (TG) as a control. HMT and substitution of rice flour with different amylose contents affected the cooking and texture quality of rice noodles. When rice noodles were made of intermediate amylose rice flour with HMT, cooking properties improved with decreased cooking loss and cooking water turbidity and thus were closer to those of control. Especially, the hardness, adhesiveness, tensile strength, and darkness of rice noodles notably increased when HMT rice flour was used. Based on the results of quantitative descriptive analysis for selected rice noodles, the noodles made of HMT CC at 105$^{\circ}C$ (CC105) had high scores for resilience and adhesiveness and low scores for hardness compared with imported commercial rice noodles and other experimental noodles such as TG, HMT GM100, TG+CC, and TG+CC105. In conclusion, rice noodles were made of composite flours containing high amylose and intermediate amylose contents or HMT intermediate amylose content rice flour.

The objective of this study was to determine the rheological characteristics and sensory evaluation of yanggaeng by using the functional properties of Momordica charantia. Dried Momordica charantia was roasted at $180^{\circ}C$ to remove its bitter taste. The results of the study were as follows : The phenolic compound of Momordica charantia was $6.30{\pm}0.17mg/g$ in water extracts, which was the highest extractive rate. The anti-oxidant activity of non-roasted and roasted samples was determined in various phenolic concentrations at $50{\sim}200{\mu}g/mL$. The DPPH activities of non-roasted and roasted Momordica charantia water and ethanol extracts were 74.06~92.71% and 86.06~94.07%, respectively. The ABTS were 36.26~98.03% and 67.02~99.60% in water and ethanol extracts, respectively. The anti-oxidant protection factor of water and ethanol extracts were 2.19~2.25 PF and 2.20~2.36 PF respectively, and TBARS were 13.81~40.97% and 23.32~82.47%, respectively. The anti-oxidant activity of ethanol extracts was higher than that of water extracts at low phenolics concentration of $50{\mu}g/mL$, while the roasted sample was higher than the sample that was not roasted. The ${\alpha}$-glucosidase inhibition activity of non-roasted Momordica charantia ethanol extracts was higher than that of water extracts, showing that there were increasing pattern depending on the increases in the phenolics concentration of Momordica charantia. The texture, such as hardness, springiness, cohesiveness, chewiness and color changed in proportion to the concentration of Momordica charantia powder. Moreover sensory characteristics, such as color, flavor, taste, texture and overall acceptability of the non-roasted sample changed in proportion to the concentration of Momordica charantia powder. However, in the roasted sample, the sensory characteristics was improved at a lower concentration (below 1%). Thus, when the yanggang was prepared by Momordica charantia powder as a minor ingredient, it would be desirable to add it after roasting, in consideration of its functional and sensory properties, and at appropriate concentration on below 1%.

Over the past two decades, the process of globalization of multinational corporations has increased at a rapid rate. One manifestation of this process is the establishment of corporate head offices in a variety of international centers to administer and coordinate, the day-to-day operations in the host countries. In establishing a subsidiary overseas a firm creates a direct link between the operations of the domestic corporate center and the foreign host center This paper investigates elements of stability and change in the international linkage patterns among domestic parent corporations and host subsidiaries over the past several decades. In particular, it seeks answers to a number of question related to stability and change in linkages among foreign centers of control and those Canadian centers selected to administer the subsidiary operations from 1970 to 1991 over the four primary sectors, namely, resources, manufacturing, services, and finance. By confirming the core stability and dispersed linkages hypotheses, the papar offers some generalizations with respect to the location and stability of subsidiary headquarters centers in Canada and their respective subsector specialties. Finally, it addresses further research avenues fer the quaternary place study.

This study investigated the effects of combined treatment of immersion liquids (adjusted pH 4.5 with Citrus junos concentrate (CL), pH 5.5 with Prunus mume concentrate (PL), or no pH adjustment, pH 6.5, control) and high hydrostatic pressure (HHP, 450 MPa) on shelf-life and quality of mackerel. In this study, we measured changes in viable cell counts, pH level, volatile basic nitrogen, thiobarbituric acid reactive substances, color analysis, volatile organic compounds, and sensory evaluation of mackerel at $4^{\circ}C$ for 20 days. CL/HHP and PL/HHP treatments reduced viable cell counts by 3 log cycles during storage compared to the control. Mackerel treated with CL/HHP and PL/HHP showed significantly lower TBARS and VBN levels as compared to the control. After combined treatment, lightness and whiteness increased but redness decreased. VOCs tests showed that contents of alcohol, acid, and ketones in mackerel fillet treated with CL/HHP and PL/HHP were relatively reduced. Especially, CL/HHP and PL/HHP suppressed production of sulfur. In the sensory evaluation, aroma, taste, salinity, hardness, and springiness of mackerel treated with combined HHP showed higher scores than the control. These results suggest that immersion liquids and HHP treatments may increase shelf-life of mackerel and maintain quality during storage at $4^{\circ}C$.

It is common description that modern society is In the era of limitless competition. In order to challenge the change of economy and its management at home and abroad, organization should be changed anew, and in this case, there accompanies conflict or trouble whether the subject of change wants it or not. Therefore, according to change, we should concern with settlement of small troubles as well as big ones, and by managing the conflict or trouble productively and originally, it should be utilized as new fatality and chance to develop something in organization. In the system organized by people, there exist various conflicts in accordance with the target and want of the system, therefore giving no freedom to each Individual member of the system, and this is an unavoidable tate in consideration of the modem society where the survival of mankind and human systems should be guaranteed. Therefore, it determines the coordinates of success of any of organizations to manage conflict or trouble well, and so, when decreasing or increasing conflicts so that the organization exerts its full influence, it is note worthy that conflict itself should be rationally and efficiently managed. In a view point of the theory of organization and its behavior, relating job satisfaction with the performance and validity of organization, the influence of individual conflict is so great on the rate of job transfer within an organization or nonattendance, even on the productivity of the organization. So, the manager to cope with conflict within an organization should devise following three plans to manage conflict for job satisfaction and conflict settlement. In conclusion, it is suggested that in order to manage conflict within an organization well, some plans to control conflict should be well utilized while giving more efforts to improving management of individual conflict, job satisfaction, validity of organization, productivity, etc and all the members of organization should remember that the Issue of conflict within an organization be recognized ad an opportunity of new development and a way to settle a trouble within an organization, and a direction of conflict management should be suggested so that new innovation ca be created.

Fruit ripening is a genetically programmed process involving a number of biochemical and physiological processes assisted by variations in gene expression and enzyme activities. This process generally affects the phytochemical profile and the bioactive principles in fruits and vegetables. To appraise the variation in bioactive principles of fruits from Rosa rugosa during its ripening process, we analyzed the changes in antioxidant and anti-elastase activities and polyphenolic compounds during the four ripening stages of fruits. Overall, an extract of unripe fruits contained the highest levels of total phenolic and flavonoid contents, radical scavenging activity, reducing power, oxygen radical antioxidant capacity, and elastase inhibitory activity, compared with the extracts of fruits at other stages of ripening. Additionally, we found that the reduction of flavonoid content occurs because of decreased transcriptional levels of genes involved in flavonoid biosynthesis pathway during the ripening process. Based on HPLC analysis, we found that the extract of unripe fruits contained the highest amount of myricetin, caffeic acid, chlorogenic acid, syringic acid, and p-coumaric acid and suggested that the antioxidant and anti-elastase activities of the extract obtained from stage 1, should be mediated by the presence of these compounds. Additionally, we analyzed the interaction sites and patterns between these compounds and elastase using the structure-based molecular docking approach, and suggested that chlorogenic acid strongly interacted with elastase. Together, these findings suggest that the maturity of fruits has profound effects on the pharmaceutical value of R. rugosa.
