This study examined the process of the formation of Deoneum, Sugungga(水宮歌), and its tendency of the change through the trace of the Pansori masters who worked in 19th century. The time that the main group of the Sugungga masters appeared in the Pansory history is estimated in early 19th century. The Sugungga masters in this time could be divided in two groups, one is the early days masters who worked in early 19th century and the other is the latter days masters who worked in middle and late 19th century. Kwon Sam-deuk(權三得), Song Heung-lok(宋興祿), Yeom Gyeo-dal(廉季達), and Shin Man-yeob(申萬葉) are the Sugungga masters who worked in early 19th century. By the records they left, I could confirm that they used the description about the dramatic characteristics in the work and Soritjo(Pansori master's tonality), like the appearance of 'Bangge(crab)' and 'Tiger', and particularly they developed which has the scene of the Rabbit's deceiving the Dragon King and Rabbit's return, 'Goandaejangja(寬大長者)', 'Gaja-Eoseoga', 'Sojinowha(笑指蘆花)', 'Apnae-Beodeuleun' and the scene of 'Rabbit's curse(the part that Rabbit curses Byeljubu)' etc. I could understand that the interest of the early days Pansori masters about Sugungga is on the characters and the latter part of the work. The separation of Dongpyeonje(東便制) and Seopyeonje(西便制) of Pansori was done in the middle and late 19th century. As the Dongpyeonje master, Song Wu-ryong(宋雨龍), Park Man-sun(朴萬順), Song Man-gab(宋萬甲), Shin Hak-jun(申鶴俊) and Yu Seong-jun(劉成俊) worked. As the Seopyeonje masters, Park Yu-jeon(朴裕全), Kim geo-bok(金巨福), Kim Su-yeong(金壽永) and Baek Gyeong-jun(白慶順) etc. sang Sugungga. The Dongpyeonje masters developed the 'Toggigibyeon(토끼奇變)' related Deoneum paying attention on the latter part of Sugungga same as the early days masters. Meanwhile it looks like that they had interest in developing the parts which belong to the middle and early parts of Sugungga like 'Toggiwhasang(토끼畵像)', 'Gogocheonbyeon(皐皐天邊)' and 'Tobyeolmundab(兎鱉問答)'. The Seopyeonje masters developed the parts belong to the early part of Sugungga, which are related to Dragon King and the courtiers in Sugung palace, like 'YongwangTansik(龍王歎息)'. And I could confirm that they developed the parts influenced by Shin Jaehyo's editorials like 'Tosahobi(兎死狐悲)' and 'Goguksancheon(故國山川)' etc. In short, I could confirm the trend that the Pansori masters in 19th century had interest in from the latter part to the early part of Sugungga. If taking a look focusing on main characters, they moved their interest in from Rabbit to the courtiers including Byeoljubu(鱉主簿) and Dragon King in Sugung palace, and it could say that, in this trend, Sori part and Deoneum were developed.

This research argues that Pansori had patrons in its development. Patrons are commonly discussed aspect of history of any art form. Pansori is no exception. While Pansori originally began as the art of the common people, Yangban class became the primary audience. This paper examines the role of royal family of Choson dynasty in development of Pansori. Heungseon Daewongun (흥선대원군) in particular was a Pansori aficionado. The record around Daewongun's involvement to Pansori proves that heavy monetary investment was made. He hosted Pansori competitions and sponsored creation of Pansori tradition, Boseong Sori (보성소리) and Gangsanje (강산제). Also the aspect of Pansori patronage lies not just in Yangban class, but also in Jung'in class, which is roughly analoguous to European bourgeois in that they were not of Yangban class, but had gained monetary status, and had aesthetics of both Yangban and commoner class. I argue that Heungseon Daewongun's ties to the Jung'in class is reflected in his actions towards Pansori artists. The traditions he had sponsored have important characteristics, including sophisticated lyrics heavily utilizing Classical Chinese poetry, highly artistic musical composition, and conservative Confucian ethics. Those characteristics indicate that the Pansori traditions sponsored by the royal patrons have changed to cater to their artistic taste and philosophy. This paper conducts a textual comparative analysis between Gangsanje Pansori Jeokbyeokga (강산제 판소리 적벽가), Dongpyeonje's Pansori Jeokbyeokga (동편제 판소리 적벽가), and Seopyeonje Pansori Jeokbyeokga, who share the same plot yet offers a stark differences in tone, philosophy, and sense of humor. Daewongun was a primary sponsor of Pansori, which proves that Yangban class and the royal family have played important role as patrons of Pansori.

Rust is one of the most destructive diseases on economically important plants such as agricultural and horticultural crops, as well as forest trees [1]. Chemical treatment is the most effective means to control rust, but use of the chemical fungicides involves inevitable risks to human health and environment [2]. Unfortunately, biocontrol is currently impracticable for rust disease management [3]. It is necessary to exploit biocontrol agents to help prevent rust diseases. As a fundamental research for future development of biocontrol agents for rusts, biodiversity of hyperparasites occurring on rust fungi was investigated. During 2006-2010, 197 fungal isolates of the rust hyperparasites were collected and isolated from various combinations of mycohosts and plant hosts in many regions of Korea. Based on morphological and molecular data, they were identified as 8 genera and 12 species. Besides, phylogenetic relationships between the hyperparasites and related taxa were inferred. A total of 114 isolates of Pseudovirgaria were obtained from rust pustules of Phragmidium spp. and Pucciniastrum agrimoniae infecting rosaceous plants. Phylogenetic analysis using multigene sequences revealed a high level of genetic variability among many isolates of Pseudovirgaria and close correlation between the isolates and mycohosts. Only two species of Pseudovirgaria, P. hyperparasitica and P. grisea are often difficult to distinguish by their morphological similarity, but on the molecular basis they were clearly differentiated from each other. There had been no previous record of P. grisea outside Europe, but the present study has proved its presence in Korea. Among six distinct groups (five of P. hyperparasitica and one of P. grisea) within the Pseudovirgaria isolates, each lineage of P. hyperparasitica was closely associated with specific mycohosts and thus might have cospeciated with their mycohosts, which probably led to coevolution. Although P. grisea possesses a host preference for Phragmidium species occurring on Rubus, it was not specific for a mycohost. P. grisea seems to evolve in the direction of having a broad mycohost range. Seventeen isolates of Verticillium-like fungi were isolated from rust sori. Based on morphological data and DNA sequence analysis, the isolates were identified as three Lecanicillium species, viz. L. attenuatum, Lecanicillium sp. 1, Lecanicillium sp. 2, and V. epiphytum. The unidenified two species of Lecanicillium appear to be previously unknown taxa. Sixty-six isolates of miscellaneous hyphomycetes belonging to 6 species of 5 genera were obtained from pustules of rust fungi. On the basis of morphological and molecular analyses, the miscellaneous hyphomycetes growing on rusts were identified as Acrodontium crateriforme, Cladophialophora pucciniophila, Cladosporium cladosporioides, Phacellium vossianum, Ramularia coleosporii, and R. uredinicola.

In July 2011, hundreds of garden cosmos (Cosmos bipinnatus) were found to be infected with a white smut in Namyangju. Further surveys in central Korea showed that the disease occurred in all the nine localities visited, with disease incidence rate of >50%. Symptoms manifested as pale-green to chlorotic areas on the leaves, followed by white mildew development on lesions. The lesions usually coalesced and became necrotic, considerably reducing the aesthetic value. Caespituli were initially hypophyllous but later epiphyllous as well. Conidiophores were 10-40 in moderately dense fascicles, hyaline throughout, mostly guttulate, $20-45{\times}2-4{\mu}m$, obtuse at the apex, and had inconspicuous conidial scars. Conidia were solitary, botuliform, hyaline, aseptate, mostly guttulate, apex rounded, base rounded to truncate, $17-24{\times}3.5-5{\mu}m$, hilum inconspicuous, unthickened, and not darkened. Sori were rounded to elongated, resulting in first white and later brown leaf spots. Teliospores embedded in the leaf tissue were subglobose to ellipsoidal, subhyaline to pale yellowish-brown, $12.5-20{\times}10-15{\mu}m$. These morphological characteristics corresponded with those of Entyloma cosmi V$\acute{a}$nky, Horita & Jage. This is the first report of white smut disease of garden cosmos due to infection of E. cosmi in Korea.

In order to investigate the relation between the phytoplankton and the catch fluctuation of set net fishing grounds located in the coastal waters of Yeosu, phytoplankton observations on the fishing ground were carried out by the training ship of Yeosu, Fisheries University from April to November in 1990, and the data obtained were compared with the catch data from the joint market of yeosu fisheries cooperative society in 1990. The results obtained are summarized as follows: 1) The phytoplanktons were more appeared in summer than in spring or autumn and their quantity was much in the shore of Dolsan-do, and little in the offshore waters distributed in the shores of Sori-do and Sejon-do, Thus, the quantity of the planktons could be used for estimating the distribution of watermass. 2) The fishes caught by the set net were arranged in the order of catch amounts as follows: Spanish mackerel > Hair tail > Common mackerel > Sardine > Anchovy > Horse mackerel > Yellow tail. The catches of anchovy and Sardine were high in April to May and Hair tail. Horse mackerel and Common mackerel were caught from June to October. But Spanish mackerel were caught during the whole period of fishing. 3) The catches by set nets showed a correlation with the quantity of phytoplanktons. The planktons appeared most in the inner waters. influenced largely by the inflow of land waters in summer. and the catches were high in summer when the offshore water was distributed least. Therefore, the most important factor influencing the catches were regarded to be the productivity of food organism in inner water into which abundant nutrients were supplied by the inflow of land waters. That is, the fluctuation of catches by set nets seemed to be influenced mainly by the productivity of food organism.

Age and growth of Ecklonia stolonifera Okamura were investigated by random quadrate sampling method at monthly intervals from February 1993 to January 1994 in Pusan Bay, southeastern coast of Korea. The size of various parts of the collected plants was periodically measured individually. An allometric relationship was established according to the total length, blade length, stipe length, stipe diameter and weight of frond. Each age group was divided according to the range of stipe length by the allometric relation. The population of E. stolonifera consisted of five age groups; 1 year ($41.5\%$), 2 years ($25.9\%$), 3 years ($21.1\%$), 4 years ($7.8\%$) and 5 years ($3.5\%$). During a year, biomass of the population increased drastically from May to September, but gradually decrease from October to January. Zoosporangial sori were observed on blades of three or more years old, from October to December. New populations were formed by zoospores, developed on shoots of three or more years old, and also they were vegetatively formed from stoloniferous haptera on two or more year old mother thalli.

The distribution characteristics of the eggs and larvae of anchovy Engraulis japonica, and environmental factors in the southern coastal waters of Korea were investigated from May to August 2009. Eggs and larvae were mainly distributed in the waters off Naro Island, Namhae Island and Saryang Island. High densities of eggs and larvae in temperatures of $19.0{\sim}24.0^{\circ}C$, salinites of 33.0~34.4 psu, DO of 6.05~8.13 mg/L and chlorophyll-a $1.2{\sim}2.3{\mu}g/L$ were observed. Water temperature in the coastal region was higher than that in the open sea, while salinity was lower. Evidence of sea water intrusion toward Sori Island and Maemul Island, and an inner-water intrusion from Yeoja Bay, Gamak Bay and Gwangyang Bay were observed. High densities of eggs in early developmental stage occurred in waters off Naro Island, Dolsan Island and Namhae Island, but high densities of eggs in a later developmental stage occurred in waters off Yokji Island and Maemul Island. During the survey period, the proportion of later developmental-stage eggs was higher in the eastern part of the study area.

The objective of this study was to understand the conservation of gene resources and provide information for mass selection' of winter bud characters among the selected populations of Kalopanax septemlobus Koidz using analysis of variance(ANOVA) tests. The obtained results are shown below; 1. Ten populations of K. septemlobus were selected for the study of the variation of winter bud characters in Korea. The results of the analysis of variance(ANOVA) tests shows that there were statistically significant differences in all of the winter bud characters among those populations. 2. Correlation analysis shows that width between Height and DBH(Diameter at breast height) characters have negative relationship with all of the characters, as ABL(Apical branch length), ABW(Apical branch width), AWBL(Apical branch winter bud length), AWBW(Apical branch winter bud width), ABT(Apical branch No. of thorns), ABLB(Apical branch No. of lateral bud) and LBL(Lateral branch length), LBW(Lateral branch width), LBT(Lateral branch No. of thorns), LBLB(Lateral branch No. of lateral bud). 3. The result of principal component analysis(PCA) for winter buds showed that the first principal components(PC' s) to the fourth principal component explains about 78% of the total variation. The first principal component(PC) was correlated with AWBW, LWBW, and LBL and the ratio of ABL/ABW and LBL/LBW out of 16 winter bud characters. The second principal component correlated with ABL, ABW, ABLB, LWBL(Lateral branch winter bud length), and LBW and the ratio of AWBL/AWBW. The third principal component correlated with ABL, ABW, LWBL, LBL, and the ratio of LBL/LBW. The fourth principal component correlated with LBL and the ratio of LWBL/LWBW(Lateral branch winter bud width), LBL/LBW. Therefore, these characters were important to analysis of the variation for winter bud characters among selected populations of K. septemlobus in Korea. 4. Cluster analysis using the average linkage method based on 10 selected populations for the 16 winter bud characters of K. septemlobus in Korea showed a clustering into two groups by level of distance 1.1(Fig. 3). As can be seen in Fig. 3, Group I consisted of three areas(Mt. Sori, Mt. Balwang and Mt. Worak) and Group Ⅱ contisted of seven areas(Suwon, Mt. Chuwang, Mt. Kyeryong, Mt. Kaji, Mt. Jiri, Muan, and Mt. Halla). The result of cluster analysis for winter bud characters corresponded well with principal component analysis, as is shown in Fig. 2.

Abnormal chloranthy was observed on Prunus mume trees grown in an orchard in Uiseong, Gyeongbuk province, Korea in 2015. Flower buds showing chloranthy were covered with numerous orange-colored sori, which were confirmed to contain spermogonia and aeciospores by stereo microscopy and light microscopy. When observed using scanning electron microscope, the aeciospores were globose, ellipsoid, or ovoid, and measured $22.8{\sim}35.6{\times}19.8{\sim}36.8{\mu}m$, with a verrucae wall ornamentation. To construct a phylogeny, the large and small subunit regions of rDNA were sequenced and compared with those of allied species by the maximum likelihood method. The isolated fungus species showed high similarities with Caeoma makinoi (Teleomorph: Blastospora smilacis), which was previously isolated from P. mume in Japan. Therefore, we initially report this fungal agent parasitic on P. mume as C. makinoi in Korea and name the disease it causes as "flower bud chloranthy disease".

Despite the importance of questionnaires, little survey methodology research on questionnaire design has been conducted in Korea. The purpose of this study was to explore whether two questionnaire forms (close-ended vs. open-ended questions) about 'the most important problem in Korea' elicited similar responses. During the 2016 Korean General Social Survey (KGSS), a random half of respondents were asked the open-ended question form and the remaining half were asked the close-ended question form. While the economy is the most mentioned response (35% vs. 33.2%) to both close-ended and open-ended question forms, there is similarity in the order of highly mentioned responses if we consider that 'politics' is not provided as one of response categories in the close-ended question form. The order of second to fourth response category is crime (24.4%), education (15.4%), and poverty (6.3%) to the closed-ended question form, and politics (10.8%), crime (9.5%), and education (7.6%) to the open-ended question form. Also, the characteristics of respondents who responded with the economy as being the most important are slightly different between the two halves in terms of age, household income, and satisfaction with economic condition. Our findings suggest that we need to be careful when we adopt questions developed in other countries and to consider using survey experiments in pre-testing questionnaire items.
