The azuki bean weevil, Callosobruchus chinensis L., which is one of the notorious stored grain insect pest. Temperature-dependent development of C. chinensis. was examined at six temperatures of 14, 18, 22, 26, 30, and 34℃ on azuki bean and cowpea seeds. The total developmental time (egg to adult) decreased with increasing temperature from 14 to 34℃ on both seeds. However, total developmental time varied from 127.9 and 125.9 days at 14℃ to 19.9 and 20.3 days at 34℃ on azuki bean and cowpea seeds, respectively. The lower temperature thresholds (Tmin) were estimated to be 9.52℃ and 10.36℃, and the thermal constants (K) were 526.31 DD and 454.54 DD, on azuki bean and cowpea using general linear model, respectively, and the lower temperature thresholds and the thermal constants estimated by Ikemoto-Takai linear models were 10.63℃ and 10.79℃, and were 466.18 DD and 436.28 DD, on azuki bean and cowpea, respectively. These findings on thermal requirements and temperature thresholds can be used to predict the occurrence, number of generations and population dynamics of C. chinensis.

The development of resistant seeds to manage this pest is a big challenge for breeders. We investigated the oviposition preference and development of C. chinensis on two susceptible mungbean cultivars (Seonwha and Gyeongseon) and one previously reported resistant cultivar Jangan, compared to the susceptible cowpea, Yeonbun, by offering a multiple choice test and a no-choice test. Additional, insect stage wise development of C. chinensis was also examined at four temperatures (20, 25, 30 and 35℃). The both choice tests results showed that the cowpea is the most suitable seed host for oviposition. Total developmental time from egg to adult stage ranged from 27.01 to 38.2 days, and developmental time was shortest on the cowpea and longest on Jangan mungbean. However, no successful development of C. chinensis on Jangan mungbean occurred at all constant temperatures. Higher rate of adult emergence and longer adult longevity were found on cowpea and mungbean except Jangan mungbean. Results suggest, higher performance of C. chinensis on cowpea and mungbean might be governed by physical as well as chemical attributes of the seeds. Thus, Jangan mungbean could be stand as a resistant one against bruchids and it could be a resistant sources for successful breeding.

This study has been carried out to identify larvae and to acquire useful biological information of insect larvae through rearing from 1997 to 2016 in HECRI(Holoce Ecosystem Conservation Research Institution). Total 148 species belonging to 16 families were collected and 45 species belonging to 12 families identified. Among identified species monophagous caterpillars dependent on maple tree were 16 species belonging to 6 families, polyphagous 29 species belonging to 9 families. The dominant family is Geometridae(50 species), second is Noctuidae(26 species) and followed by Tortricidae(18 species).

The population size of Red-spotted Apollo Butterfly(Parnassius bremeri) has been reduced because of their habitats destruction and partly climate change. Estimation of metapopulation size and survival day of Red-spotted Apollo Butterfly was made in Samcheok where release was carried for 5 years, Korea, by using the mark-release-recapture method. 421(female: 188, male: 233) of Red-spotted Apollo Butterfly were captured and 177 individuals(female: 89, male: 88) were recaptured and rates of recapture was 42%. Average of survival day was 3.59 and max survival day was 11. The migration of Red-spotted Apollo Butterfly was occurred significantly between short patches. Their max distance of migration was 6.74km. Estimate of P. bremeri was from minimum 125 to maximum 1844.

This study was conducted to investigate exact life cycle and Parnassius bremeri’s response to heat shock stress from 2012 to 2016 in Holoce Ecosystem Conservation Research Institution through captive breeding. About 16 days(15.7±0.3days) later embryo in eggs were developed as pharate first instar and the eggs of Parnassius bremeri possessed the ability to undergo an extended aestivation hosting a fully developed pharate 1st instar larvae within the chorion. Pharate 1st instar in egg hatched from late in November to early in December about 194 days(194.3±1.1days) later. All pharate 1st instar in egg and out of egg survived at 25℃, 35℃. In case of 45℃ survival rate of pharate 1st instar in an egg (93.8±6.3%) was significantly higher than those (22.2±10%) of pharate 1st instar out of an egg. All was dead at 47.5, 50, 52.5 and 55℃.

It was an honor to give my speech to the American public about the Jeju 4.3 Grand Tragedy as one member of the Jeju 4.3 delegation. On March 27, 2015 I supported the “Petition for a Joint South Korea and United States Jeju 4.3 Incident Task Force on Social Healing through Justice.” On August 15, 2016, I was happy to write the foreword “Jeju 4.3 Grand Tragedy becomes Human Spirit in the Asia Pacific,” for the new book about Jeju 4.3 titled, “Jeju 4.3 Grand Tragedy during ‘peacetime’ Korea : The Asia Pacific Context (1947-2016). On September 8, 2016, we proceeded with “Authentic 4.3 Jeju Tragedy Reconciliation as a symbol of Peace in Asia” at the Jeju 4.3 Tragedy Reconciliation Conference 2016 in Washington D.C.

Rotaviruses are enteric pathogens causing acute watery dehydrating diarrhea in humans and animals. The importance of group C rotavirus (GpC-RV) infections has not been established as the studies on the GpC-RV have been hampered by the lack of an in vitro culture system. However, diarrheal diseases associated with GpC-RV have been gradually increasing worldwide. In this study, VP6 gene of bovine GpC-RV Korean isolate was expressed, and monoclonal antibodies (mAbs) against VP6 were produced and characterized. The VP6 gene was cloned and expressed based on a baculovirus expression system. Indirect fluorescence antibody (IFA), polymer chain reaction (PCR), and Western blot assays were used to confirm expression of VP6 gene synthesized by the recombinant baculovirus. Eleven mAbs against VP6 were produced using expressed VP6. Cross-reactivity of the mAbs was assessed with recombinant VP6 proteins from porcine GpC-RV and human GpA-RV, or different serotypes of group A rotavirus strains by IFA test. Some mAbs reacted with intact porcine GpC-RV Cowden strain as well as bovine GpC-RV VP6 recombinant baculoviruses, but not with human and animal GpA-RV strains. The VP6-specific mAbs might be useful to develop immunodiagnostic tests such as rapid diagnostic kit, IFA and enzyme-linked immunosorbent assay (ELISA) for detection of GpC-RV.

The Sausage radio relic is the arc-like radio structure in the cluster CIZA J2242.8+5301, whose observed properties can be best understood by synchrotron emission from relativistic electrons accelerated at a merger-driven shock. However, there remain a few puzzles that cannot be explained by the shock acceleration model with only in-situ injection. In particular, the Mach number inferred from the observed radio spectral index, Mradio  4.6, while the Mach number estimated from X-ray observations, MX−ray  2.7. In an attempt to resolve such a discrepancy, here we consider the re-acceleration model in which a shock of Ms  3 sweeps through the intracluster gas with a pre-existing population of relativistic electrons. We find that observed brightness profiles at multi frequencies provide strong constraints on the spectral shape of pre-existing electrons. The models with a power-law momentum spectrum with the slope, s  4.1, and the cutoff Lorentz factor, e,c  3−5×104, can reproduce reasonably well the observed spatial profiles of radio fluxes and integrated radio spectrum of the Sausage relic. The possible origins of such relativistic electrons in the intracluster medium remain to be investigated further.

This study examined the factors affecting the bubble generation of a motor driven bubble generator to develop a heating unit using hydrodynamic cavitation. This study also investigated the heat production and thermal efficiency by changing operating conditions. Bubble generation using the 25 ℓ-capacity motor is driven bubble generator was confirmed visually in various experimental conditions: three levels of motor powers(1, 3, 5 HP), two levels of revolutions(1800, 3200 rpm), and two levels of internal pressures of the bubble generator(the atmospheric pressure, pressurized air). After constructing the heating unit, heat production, and thermal efficiency were measured in the following experimental conditions: two levels of motor powers(3, 5 HP) and three levels of water quantities(102, 152, 230 kg). And then specifically temperature increasing rate and specific consumed energy required for the heating unit design were calculated. Bubbles were generated stably at 1,800 rpm and pressure from 0~0.8 bar. When heating water around 30℃, specific temperature increasing rate was maximized at 0.247℃/min and 0.002422℃/min-kg. Thermal efficiencies were 121% with only motor driving power as input energy and 98% with both motors driving power and water circulating pump driving power as input energy. This showed that the heating unit using hydrodynamic cavitation had higher thermal efficiency than the existing combustion boiler. Maximum specific consumed energy was 0.0270 KJ/min-kg-℃. This study confirmed that water can be heated with the heat caused by the explosion of the bubbles generated by hydrodynamic cavitation. And the results of this study could be utilized for commercial use because it showed much higher thermal efficiency than the existing combustion boiler.

For Japanese and Korean learners of English as a second language (ESL), the substitution of [š] (the palatalized [s]) for /s/, is a well‐documented error pattern, in which a phonological rule of the learnerʹs native language (L1) is transferred to the production of the target language (L2). A necessary task for learners to achieve target‐appropriate production of L2 sounds is to overcome such rules of L1 phonology. Motivated by anecdotal observations, this work investigates any potential relations between the pronunciation accuracy of the target English /s/ and some social factors of Korean and Japanese ESL learners: L1, gender, academic major, LOR, and attitude. Two sets of production data, spontaneous speech and isolated words reading, were collected from sixteen Japanese and thirteen Korean learners of English. Then, a series of impressionistic analyses of the data was conducted. The findings indicate that the level of target‐appropriate L2 production is, to an extent, related to the learnerʹs personal and social factors.

In early 2015, L’Oréal’s luxury cosmetics brand LANCÔME launched a product called Miracle Cushion™, a sponge soaked in liquid foundation. By integrating a cosmetic formula with a sponge in a compact case, it distinguished itself from other conventional makeup products, e.g., liquid foundation in a glass bottle or pressed powder in a portable compact. On Lancôme’s website, Miracle Cushion™ is described as follows: “a foundation revolution has arrived – liquid makeup in a cushion.” LANCÔME’s “revolution” actually originated from AMOREPACIFIC, Korea’s number one beauty group which had a sales revenue of KRW 4.7 trillion (USD 3.9 billion) in 2014. By launching Air Cushion® in March 2008, AMOREPACIFIC created a new makeup product category called “cushion.” By July 2015, the total cumulative number of AMOREPACIFIC’s cushion products sold in 13 countries was 63 million units. In 2014 alone, more than 26 million units were sold – one every 1.2 seconds. The sales revenue was KRW 641 billion (USD 542 million), which accounted for more than 13% of AMOREPACIFIC’s total revenue. AMOREPACIFIC launched Air Cushion® under IOPE, one of its premium brands. The company initially positioned Air Cushion® as sunscreen. Equipped with mass production facilities, AMOREPACIFIC sold 517,000 units of cushions in 2010, which accounted for KRW 14.5 billion (USD 12.2 million). Furthermore, the company started to automate the entire manufacturing process for cushions. With this automation, the sales revenue of Air Cushion® in 2011 reached KRW 33.6 billion (USD 28.4 million) - more than doubled compared to 2010. Obviously, it was a huge success for sunscreens under a single brand. From 2012, AMOREPACIFIC began to expand cushions for other in-house brands besides IOPE. Simultaneously, AMOREPACIFIC started to reposition cushion as makeup “foundation,” not “sunscreen.” HERA, AMOREPACIFIC’s luxury brand with a strong heritage in color makeup, took the initiative in repositioning cushion. This was also a strategic decision to diversify distribution channels: the main distribution channels of premium brands such as IOPE were Sephora-like specialty stores and discount stores whereas the primary distribution channels of luxury brands such as HERA were department stores and door-to-door networks. With HERA focused on domestic market expansion, LANEIGE, the most globalized brand of all in AMOREPACIFIC, pioneered the global market for cushions. Starting from its entry into Hong Kong and China in 2002, LANEIGE had already expanded its presence in more than 10 countries including Singapore, Malaysia, and Vietnam. Specifically, LANEIGE was perceived in most Asian countries as a cosmetics brand spearheading “K-Beauty” trends, part of the “Korean Wave” phenomenon. Thus, LANEIGE capitalized on its brand reputation accumulated over the years in the Asian market to expand cushions. LANEIGE designed a brand concept for its cushion as BB Cushion to make the most of the popularity of BB creams across Asia. In 2012, LANEIGE BB cushion was first launched in Singapore in January, followed by Malaysia, Thailand, and Vietnam in March, and finally Taiwan in April, all prior to its release in Korea in May. Initially, it emphasized the brightening function to fulfill the demand for whitening products already popular throughout Asia. From 2013, LANEIGE started to offer a variety of product lines customized to different consumer needs from each country. For example, LANEIGE launched BB Cushion Pore Control for consumers in hot, humid areas of Southeast Asia and BB Cushion Anti-aging for consumers in extremely cold and dry areas of China. Starting with HERA and LANEIGE in 2012, AMOREPACIFIC continue to release cushions under other brands by stages - SULWHASOO, ETUDE HOUSE in 2013, and INNISFREE, MAMONDE in 2014, etc. Every cushion product launched under different brands was named “cushion.” For example, HERA UV Mist Cushion, LANEIGE BB Cushion, SULWHASOO Perfecting Cushion, ETUDE HOUSE Precious Mineral Any Cushion, INNISFREE Water Glow Cushion, MOMONDE Cover Powder Cushion, etc. With the consistent labeling, AMOREPACIFIC succeeded in categorical differentiation. Stimulated by the widespread popularity of AMOREPACIFIC’s cushion foundations, competitors followed. Among local companies, LG Household and Healthcare was the first to enter into the cushion market in August 2012. Among the foreign brands, it was Lancôme. This paper is trying to understand how to achieve breakthrough innovation and create a new product category in the mature market such as cosmetics by analyzing the case of AMOREPACIFIC’s cushion.

Since there are intimate relationships between customers and customer equity, this study aims to explore the effects of covert and overt narcissistic consumers on luxury brands’ customer equity. The authors confirm the significance of the previous qualitative study on the two types of narcissists in regard to luxury consumption and customer equity by using quantitative methods. Narcissism basically means a self-loving tendency in one’s mind. People with narcissism overly respect themselves and act in an egotistical way(Lasch, 1980). Some scholars state that there are distinctions in narcissists in that they can be either overt or covert. Covert narcissists are hypersensitive, feel inferiority, pursue social power and honor, crave compliments, have strong jealousy, feel dissatisfaction with work and society, have fragile egos, and a likelihood of conscience contamination. People with covert narcissism also try to avoid damage both physically and emotionally. Overt narcissists pursue social success, lack depth, ignore and devalue others, have strong aspirations, and passion for ethics, social politics, and aesthetic issues. They believe in their own grandiosity, which causes direct expression of exhibitionism, self-importance, and a preoccupation with getting the attention and admiration from others(Hendin & Cheek, 1997; Park & Kang, 2013; SALMAN AKHTAR & Thomson Jr, 1982).

Cordyceps species are known to produce numerous active components and are used for diverse medicinal purposes because of their varied physiological activities, including their anticancer, anti-inflammatory, and antimicrobial effects. Cordycepin, one of adenosine analogues, differs from adenosine in that its ribose lacks an oxygen atom at the 3' position. Cordycepin has been reported to be a main effector molecule in Cordyceps extracts that executes antiviral activities against several viruses including influenza virus, plant viruses, human immunodeficiency virus (HIV), murine leukemia virus, and Epstein-Barr virus (EBV). In addition, adenosine and its deaminase inhibitor showed strong antiviral potentials that were about 4,000 times more potent than the activity of the direct inhibitory effect by adenine arabinoside on Herpes simplex virus (HSV)-1, suggesting adenosine itself plays an important role to produce antiviral activities. In this study, we show that cordycepin and adenosine possess antiviral and antitumor activities against EBV and EBVassociated gastric carcinoma, respectively. Furthermore, we report epigenetic mechanisms used by cordycepin and adenosine to exert their antiviral and antitumor effects.

The Toothbrush radio relic associated with the merging cluster 1RXS J060303.3 is presumed to be produced by relativistic electrons accelerated at merger-driven shocks. Since the shock Mach number inferred from the observed radio spectral index, Mradio  2:8, is larger than that estimated from X-ray observations, MX . 1:5, we consider the re-acceleration model in which a weak shock of Ms  1:2 - 1:5 sweeps through the intracluster plasma with a preshock population of relativistic electrons. We nd the models with a power-law momentum spectrum with the slope, s  4:6, and the cutoff Lorentz factor, e;c  7-8104 can reproduce reasonably well the observed proles of radio uxes and integrated radio spectrum of the head portion of the Toothbrush relic. This study conrms the strong connection between the ubiquitous presence of fossil relativistic plasma originated from AGNs and the shock-acceleration model of radio relics in the intracluster medium.

High pollutant-loading capacities (up to 319 times its own weight) are achieved by three-dimensional (3D) macroporous, slightly reduced graphene oxide (srGO) sorbents, which are prepared through ice-templating and consecutive thermal reduction. The reduction of the srGO is readily controlled by heating time under a mild condition (at 1 10–2 Torr and 200°C). The saturated sorption capacity of the hydrophilic srGO sorbent (thermally reduced for 1 h) could not be improved further even though the samples were reduced for 10 h to achieve the hydrophobic surface. The large meso- and macroporosity of the srGO sorbent, which is achieved by removing the residual water and the hydroxyl groups, is crucial for achieving the enhanced capacity. In particular, a systematic study on absorption parameters indicates that the open porosity of the 3D srGO sorbents significantly contributes to the physical loading of oils and organic solvents on the hydrophilic surface. Therefore, this study provides insight into the absorption behavior of highly macroporous graphene-based macrostructures and hence paves the way to development of promising next-generation sorbents for removal of oils and organic solvent pollutants.
