The Steptoean Positive Carbon Isotope Excursion (SPICE) is found in the Machari Formation which was interpreted to have been deposited on the middle to outer carbonate ramp environment. The Machari Formation is the Middle to Late Cambrian in age and distributed in the Yeongweol area, Gangweon Province, Korea. The SPICE event in the Machari Formation begins with the first appearance datum of trilobite Glyptagnostus reticulatus and ends with the first appearance of datum of trilobite Irvingella. The SPICE is found in approximately 120 m thick sequence and ${\delta}^{13}C$ values in the SPICE interval range from 0.6 to 4.4‰. The SPICE in the Machari Formation is interpreted to be caused by burial of organic matter in the sea floor and subsequent increase of $^{13}C$ isotope of the Late Cambrian ocean. The SPICE interval in the Machari Formation corresponds to the highstand to transgressive systems tracts.

Cold damage of mulberry in Kangweon Province is generally higher that of other provinces. Farmers suspected cold damage caused from late summer fertilizer. To understand the effect of late summer fertilizer. To understand the effect of late summer fertilizer, two additional summer fertilizer times, August 10 and 20, were compared with conventional time(June, 20). Mulberry yield increased by 10~30% in 1m middle cut, and 10~17% in leaf picking method in August 10 treatment, compared with conventional. Additional summer fertilizer did not increase cold damage rate of branches. Leaf yield in leaf picking was higher by 6~29% that that of 1m middle cut.

The aim of this paper is to research phonological and morphological features in Korean Voices from Berlin. The Korean Voices from Berlin was recorded in 1917 at Berlin by 5 Korean prisoners engaged in World War I, some of them came from North Hamgyeong Province, the others came from Pyeongan Province, therefore these data show a North Korean regional dialect. The data are composed of three materials, counting numbers, reciting scriptures and singing folksongs. The results of this research are as follows. 1) The consonant system of Korean voices is similar to standard Korean. The 19 consonants are classified according to 5 manners of articulations and 5 points of articulations. 2) The liquid /l/ has three allophones, [ɾ] appeared in an onset position, [l] in a word medial coda position or preceded by [l], [ɹ] in a word final coda position. 3) The vowel system of Korean voices is similar to early 20th Korean's. It has 8 monophthongs, /a, ʌ, o, u, ɯ, i, e, ${\varepsilon}$/. 4) The 1 to 10 numbers in Korean voices are similar to Middle-Korean numerals. 5) The genitive particle '/ɯi/의' is pronounced [i], [ɯ], [${\varepsilon}$], especially [ɯ] is appeared in Sino Korean. 6) The /l/-deletion of conjugations are similar to Middle-Korean, /l/ deletion always occurred, if [+cor] consonants are followed.

This study examined the subcomponents of the local environment that have an important influence on the life satisfaction of people living in single-person households and analyzed how the causal relationship between these variables differs between generations. Specifically, the local environment was classified into the following subcomponents: convenience, comfort, safety, healthcare, and neighborhood relationships. This study analyzed the data of 3,260 respondents from single-person households in the 2020 Residents' Quality of Life Survey in Gyeonggi Province. As a result, it was found that the perception of all subcomponents of the local environment had a positive effect on the life satisfaction of people in single-person households. The effect of neighborhood relationships was relatively large compared to other subcomponents. Next, the influencing factors on life satisfaction of people in single-person households showed differences between generations, which were defined by this study as youth (under age 35), middle-aged (35-64), and elderly (65 and older). Convenience and safety for the youth group and neighborhood relationship for the middle-aged group were most important. The elderly group was most affected by healthcare. The proportion of single-person households worldwide, including in Korea, is gradually increasing, and considering this, this study provides important policy implications.

This study investigates the technical level and industrial structure for the case of the Gazelle industry in Chungnam Province. As a results of the empirical study, the Gazelle industry of Chungnam Province shows a competitive position in terms of scale and growth capacity, which. in turn, provides income and tax collection effects due to the high level of industrial efficiency. Among the Gazelle industry of Chungnam Province, low-level technology industry, compared to high and middle-level technology industries, accelerates higher level of agglomeration and industrial growth, which provides a rapid change of industrial structure of the province. Theses research results imply that research and development investment in the Gazelle industry is essential and industrial development strategy should be conducted via step-by-step with business scale quotient (BQ) and industrial growth rate (IG). Meanwhile, there should be a serious policy review whether low-level technology industry is better off for the province compared to high and middle-level technology industries. This study expects that regional industrial policy applying the concept of Gazelle industry can accelerate regional development since the Gazelle industry contributes to the high level of income growth and employment creation.

This study was carried out to characterize pinus densiflora forests in middle province (Mt. Seolag, Mt. Taebaik) south province (Mt. Sokli, Mt. Jiri) and south-coast province (Mt. Daedun) of Korea. The appearance species in the P. densiflora alliance included 325 taxa and varied according to the direction of slopes. The steeper the slope was, the fewer number of taxa were observed. The floristic composition of south-coast province was gradually changing to the south hemispheric factors. Dominant species groups of P. densiflora alliance were classified into P. densiflora, Quercus serrata ( layer), Rhus trichocarpa ( layer), Lespedeza maximowiczii var. tomentella (S layer), Artemisia keiskeana, Carex humilis var. nana, Spodiopogon sibiricus (K layer). Quercus variabilis, Fraxinus sieboldiana and Styrax japonica association were formed under the P. densiflora alliance. Quercus, Rhus, Lespedeza and Rhododendron groups maintained high ecological relationships one another. The soil factors (pH, organic matters, and water field capacity)and relative light intensity tended to show negative correlation, which were significantly different among provinces. The P. densiflora forests of Korea were classified into one alliance and four associations, that is, pinion densiflorae Suz.-Tok. 1966, Quercetum variabilae ass. nov., Quercetum mongolicae ass. nov. Fraxinetum sieboldianae ass. nov. and Styraxetum japonicae ass. nov.

We evaluated the nutritional status of 116 Songmyun middle school students. The means of height and weight were similar to the standards published by the Ministry of Education(1991). The height of 79% of the subjects was in the normal range, and the height for 11% was below the normal range. While 27% of the subjects were underweight, 18% and 8% were overweight and obese, respectively. The percentage of anemia was 29%, and the mean urinary urea nitrogen to creatinine ratio was 8$\pm$4. Total daily energy and nutrient intake was 48-103% of RDAs, and especially calcium and iron intake was very low. Carbohydrate, protein and fat intake was 71%, 12% and 17% of total calories, respectively. Breakfast, lunch, dinner and the between meals provided 20%, 37%, 26% and 18% of total energy intake. Energy and nutrient intake from lunch box was 52-95% of the 1/3 RDAs. Our data suggest that the nutrition education for the meal planners of the subjects is necessary to improve the nutritional status of the subjects. In addition, the school lunch program is recommended.
