Tattoo, which has been 5000 years' history is the symbol of the collective society. It was used as one of the methods not only to defense and camouflage but also to decorate themselves. In modern society, tattoo culture is either limited to ethnic minorities or be used as a decorative element of personal preference. Among them, the Chinese ethnic minority, the Dai, is still maintaining its tattoo culture, but gradually faded. Hence, the necessity of protecting the tattoo culture of the Dai is essential. The procedures and methods of this study were conducted by analyzing an antique book, explore residential areas, data research, and data collection through interviews. According to research, the tattoo culture of the Dai has been consistently passed down through traditional tattoo pictorial books, the memories of tattooists, and the stories of people who got tattoos. However, the Dai's traditional culture and customs are influenced by the China political reform between 1952 and 1956, confirming that the size of tattoo culture was reduced than before and evanesces. As a result, in order to inherit the ethnic minorities Dai's tattoo heritage, records of tattoo culture are required. Besides, it is considered that the records of tattoo culture and interpretations of tattoo culture by tattooists and the people who got a tattoo due to aging in the future should be studied.

Testing approaches for configurable software product lines differs significantly from a single software testing, as it requires consideration of common parts used by all member products of a product line and variable parts shared by some or a single product. Test coverage is a measure of the adequacy of testing performed. Test coverage measurements are important to evaluate the adequacy of testing at the software product line level, as there can be hundreds of member products produced from configurable software product lines. This paper proposes a method for measuring code coverage at the product line level in configurable software product lines. The proposed method tests the member products of a product line after hierarchizing member products based on the inclusion relationship of the selected features, and quantifies SPL(Software Product Line) test coverage by synthesizing the test coverage of each product. As a result of applying the proposed method to 11 configurable software product line cases, we confirmed that the proposed method could quantitatively visualize how thoroughly the SPL testing was performed to help verify the adequacy of the SPL testing. In addition, we could check whether the newly performed testing for a member product covers the newly added code parts of a feature.

To understand the process of publication and distribution of ancient Korean novels under the Joseon dynasty and Japanese occupation, collecting information on the publication of various printed materials and estimating their publication date through various methods is extremely important. In this study, the characteristics and differences that appeared in the woodblock printing process were investigated using image comparison among editions of the Honggildongjeon (Tale of Honggildong) of Wanpanbon (完板本) (published in the Jeonju region) with other commercial editions of the ancient Korean novels. Additionally, the publication year of each edition was estimated. Printed images of different versions were compared with those of a recently discovered original series version and the changes in the process of carving replacement woodblocks were investigated and summarized. Various phenomena, such as differences in fonts, borderline shapes and integrity of printed characters, appearing in woodblock prints provided useful information for determining chronological relationships between the prints and estimating the approximate publication year for each edition. The various characteristics of woodblock printing obtained through this study are expected to serve as a reference for estimating the relationship between the printing method and the approximate publication date of old books and paper-based printed historical records.

Consumers have been increasing their interests in firms' ethicality as well as in the features of the firms' products when they decide to purchase a certain product. Recently, fair trade is considered to be a type of ethical marketing in the business-to-consumer market. In this regard, the effects of fair trade-based marketing on firm performance have become the center of academic and managerial concerns. Despite this importance, few studies have investigated whether fair-trade is a source of competitive advantage or just a cost of doing business. The present research attempts to provide evidence of how fair trade-based marketing influences competitive advantage. Two experimental studies were conducted to explore consumers' purchase intention, which can be a proxy of competitive advantage, in a foreign product-consumption context. Drawing on the stakeholder theory, the first study was performed to examine the effects of fair trade marketing on consumers' purchase intention through a within-subjects design. In addition, building on the signal theory, the second study was executed to test the effects of a fair trade mark on consumers' purchase intention. The findings of the current research reveal that consumers prefer fair trade-based products to others and that when it comes to fair trade-certified products, consumers are more likely to purchase products with that certification than otherwise, even when those products are sold at higher costs than rival products. Interestingly, the results of this research present that there is a significant difference of consumers' purchase intention of a fair trade-based product between two different marketers. This implies that fair trade-based products should be differentially distributed and targeted at a certain type of consumers.

Objectives: This study reports the findings that support the efficacy of herbal medicine (HM) for premenstrual syndrome (PMS). Methods: We conducted meta-analysis of findings from randomized controlled trials (RCTs) for PMS treated with HM. The articles were published before July 2022, located using 9 databases (Pubmed, EMBASE, Cochrane Library, CINAHL, CNKI, CiNii, SCIENCE ON, KoreaMed, OASIS). Results: We observed 2,034 studies, of which 23 RCTs met our inclusion criteria. The risk of bias in the included studies was relatively unclear or high. Meta-analysis of 3 RCTs showed that HM group had a significantly higher total effective rate than the western medicine group (RR 1.20 [95% CI 1.06, 1.36, p=0.004]). Meta-analysis of 1 RCT showed that HM group had a significantly lower symptom score (MD -3.04 [95% CI -5.36, -0.72, p=0.01]), while there was no significant difference in daily record of severity of problems scale (MD -20.52 [95% CI -49.33, 8.29, p=0.16]). Conclusions: HM significantly improved PMS symptoms than general treatment and no serious adverse events were reported. However, the evidence on the effectiveness and safety of HM for PMS was not enough to provide reliable results due to the small number and low quality of included studies. We believe that rigorous RCTs will lead to more reliable evidence of the intervention.

The garden culture of Korea and Japan have been commonly influenced by Wonrim culture of China. Nevertheless, each culture has been settled down through the development of the two separate garden cultures, The purpose of this study is to grasp the formation background and main agent of development through theoretical consideration of gardens in Japanese Imperial Garden Katsura Imperial Villa, which is the origin of the representative garden making style-Circuit Style Garden, to look into the characteristic of spatial organization elements by conducting on-site survey and interview with a garden manager, and to obtain elementary views on Katsura Imperial Villa which is an important case of Japanese garden culture. As a result; first, Katsura Imperial Villa is the first jicheol juyu(round tour of ponds and springs) circuit style garden created by Toshihito Emperor and his son Toshitada Emperor, who were well-versed in Waka through the dynasty literature based on the story of Genji throughout about two generations lasting about 30 years; space composition of this garden is divided into land, island and water space, being composed of a total of 36 space components. Second, Katsura Imperial Villa was created with the primary goal of making a round tour around the garden land by arranging tea pavilions, such as Shokintei, Shokatei and Shoiken, etc., which introduced the then game culture into the garden. Third, the personnel in Katsura Imperial Villa intended to enjoy the scenic characteristics of the area where Katsura Imperial Villa was located from the interior of the garden by making Gepparo which was a tea pavilion for enjoying the rising moon on the hill even a litter faster and longer by piling up earth and setting up stone walls north of Koshoin which was a structure located west of the garden land.

To find out the way to be able to prolong the grazing years of mixed pasture under Cheju summer-hot weather, an experiment designed with split plot (main plot : 3 cutting-plant height such as 15cm, 30cm and 45cm and sub plot : 4 white clover varieties such as Regal, Tahora, Brown and SRVR) was carried out at Cheju Agricultural Experiment Station during the period from Sept. 1994 to Oct. 1996 Dry matter yield in 15cm plant height in cutting dates has shown significantly lower increase than those in 30 and 45cm(P<0.05). There was highiy significant increase in dry matter yield of Brown plot when compared with other varieties of white clover in 2nd year(P<0.01). There was no difference on botanical composition of mixed sward as affected by plant height in cuttings dates in 2nd year. The percentage of white clover tends to lower in white clover varieties Brown and SRVR when compared with Regal and Tahora. The rate of weed was not affected by plant height in cutting dates and white clover variety in mixed pasture at last cutting time of 2nd year. In 15cm plant height, concentration of ADE and NDF was the lowest one while P contents was the highest one(P<0.01). Potassium contents was the lowest one in 30cm plant cutting height(P<0.05), and nitrogen showed statistically interaction between plant cutting height and white clover variety(P<0.01). White clover variety was no effective on concentration of constituents in mixed pastures. In conclusion, white clover variety SRVR harvested at 15cm plant height is effective on nutrient value of pasture and balance of grass and white clover in botanical composition.

This study was carried out to determine the effects of the fertilization levels and oversowing treatment on liveweight gain of glazing cattle, changs of botanical composition, and dry matter(DM) yield in tall fescue dominant mixed pasture during the grazing period. The treatments were T$_1$(low fertilizing; 120-100-100 kg/ha), T$_2$(medium fertilizing; 280-200-200 kg/ha) and T$_3$(medium fertilizing+oversowing). The botanical composition of tail festuce was increased in T$_1$ and that of tall fescue, orchardgrass and pernnial ryegrass in T$_3$ was 30.5%, 23.8% and 24.1%, respectively. The total forage DM yield was the highest in T$_3$, and the average stocking rate (animal unit; AU) per day during the grazing period in T$_1$, T$_2$ and T$_3$ was 2.4 AU. 3.0 Au and 3.3 AU, respectively. The total grazing days (animal unit day; AUD) in T$_3$(664 AUD) was higher than that of T$_1$, and T$_2$. There is no significant difference in average daily liveweight gain per head among the treatments but daily liveweight gain per ha in T$_3$ was higher than that of T$_1$, and T$_2$. The total liveweight gain per ha during the grazing period in T$_1$, T$_2$ and T$_3$ was 601kg. 762kg and 877kg, respectively. The herbage consumption per day per 100kg LW was similer among the treatments but crude protein, P, K and Ca contents in herbage were increased with medium fertilization levels(T$_2$) and with oversowing(T$_3$).

The effect of different particle sizes of scoria inclusion in weanling-growing-finishing diets on growth performance and carcass quality was investigated in this study. Treatments were the control (basal diet), and 3 scoria treatments with different partical sizes (500, 1,000, 1,700 ${\mu}m$, respectively) in which $3\%$ of basal diet was replaced by scoria. This study was carried out for 143 days using 84 pigs. Each treatment has 3 replicates (4 gilts and 3 barrows per pen). 1. During nursery period, all scoria treatment levels showed poor Average daily gain (ADG) and feed efficiency compared to the control. During growing period, The ADG and feed efficiency of pigs fed the $1,000\;{\mu}m$ swine treatment tended to improve. For the whole growth period (d 0-143), $1,000\;{\mu}m$ scoria treatment showed significantly higher (P<0.05) ADG and feed efficiency than the $1,700\;{\mu}m$ scoria treatment. 2. Carcass weight was higher in all of scoria treatment levels Either the control (P<0.05), while backfat thickness was unaffected among treatments. Carcass Grade A or B grade appearance was more evident in all of scoria treatments compared to the control. 3. Hunter L value was numerically higher in the control while there was no significant differences among the control, $1,000\;{\mu}m$ scoria and $1,700\;{\mu}m$. Hunter a value was highest (P<0.05) in $1,000\;{\mu}m$ scoria, while Hunter b values were not influenced by the scoria treatment levels. 4. The different scoria treatment levels reduced N and P excretion. For growing period, $1,000\;{\mu}m$ scoria was most efficient in reducing N excretion, while during the finishing period, $1,700\;{\mu}m$ scoria was the best. The P excretion was affected by scoria particle size during growing-finishing periods rather than weanling period. The above findings indicated that the inclusion of different scoria partical sizes in nursery diet resulted to adverse effects on growth performance in contrast to the growing finishing diets wherein the growth performance and carcass quality were not affected. Finally, scoria regardless of particle size proved to be effective in reducing N and P excretion and can be considered an environment friendly mineral source for growing-finishing hog diets.
