We investigated changes in quality during storage of cookies prepared with pine needle powder these are functional foods. We chose the quantity of pine needle powder (0%, 3%, 6%, or 9%, by weight) and storage time (1 day, 3 days, or 5 days) as independent variables and conducted sensory tests, measured chromaticity, and investigated physical properties. Differences in sweetness (p<0.05), bitterness and overall preference (both p<0.001), were noted on sensory testing, and were all significant. The degrees of brightness (p<0.001), redness (p<0.001), yellowness (p<0.001), and hardness (p<0.05) increased significantly as pine needle powder content increased, and changes in brightness and redness (both p<0.01) during storage were also significant.

This study examined antioxidative activities and quality characteristics of noodle produced with the pine needle powder as 0.5, 1.0 and 2.0% (v/v to korean wheat powder). DPPH radical scavenging activity, reducing power, antioxidative activities, tyrosinase inhibitory activity of the solvent fraction extracts increased in a dose-dependent manner. Especially, butanol fraction showed high DPPH radical scavenging activity, reducing power, antioxidative activities and tyrosinase inhibitory activity. The weight, volume, water absorption and turbidity of cooked noodles containing pine needle powder increased as pine needle powders were higher. When the amount of pine needle powder increased, the Hunter L (lightness) and a (redness) value of cooked noodles decreased, but b (yellowness) value increased. The texture of noodle containing pine needle powder have decreased than control using only Korean wheat powder in hardness, cohesiveness, springiness, gumminess and chewiness. The results of sensory evaluation of cooked noodles containing pine needle powder indicated that the cooked noodles with 1.0% pine needle powder showed the highest value.

The setting time is a very important factor affecting the quality of tunnel lining and reinforcement of inclined slope etc. Currently, however, the quality criteria of accelerating admixture to improve it is not established well. In this study, evaluation on setting time measuring methods of cement mixed a accelerating admixture (AA) was performed using Gillmore and Vicat needle test methods. For both test methods, the setting time for addition at a time was better than post addition regardless of initial setting and final setting. For Gillmore needle test method, two types of measuring methods were selected and it is noted that setting time with cement type under the same accelerating admixture can be different. Accordingly, manufacturing company shall develop a less sensitive accelerating admixture to cement type. For Vicat needle test method, six types of measuring methods were used and a proper measuring method of the admixture were proposed as follows: (1) the temperature of materials used shall be controlled exactly and (2) to evaluate its properties, an admixture usage of $5\%$ (ratio of cement weight) is recommended.

Objective: Pine needles are rich in many nutrients and exhibit antibacterial and antioxidant biological activities; however, the effects of different production methods of pine needle additives on the growth performance and intestinal flora of broiler chickens are not known. Methods: Normal diets were supplemented with pine needle fermentation juice (PNF), pine needle soaking juice (PNS), or pine needle powder (PNP), and the associated effects on growth performance, relative organ weights, intestinal development, intestinal histological morphology, intestinal flora, meat quality, and serum indicators in broiler chickens were observed. Results: The results showed that PNF, PNS, and PNP all significantly improved feed utilization and promoted the growth and development of broilers. All three additives also significantly improved the structure of the intestinal flora, specifically increasing the diversity of bacteria; increasing the abundance of beneficial bacteria, such as Faecalibacterium, Rikenella, and Blautia; and decreasing the abundance of harmful bacteria, such as Staphylococcus. The antioxidant properties of pine needles were also found to intensify lipid metabolic reactions in the blood, thus leading to lower triglycerides and total cholesterol. Meanwhile, high doses of PNF reduced jejunum and ileum weights and also increased meat yellowness. Lastly, none of PNF, PNS, or PNP had an effect on relative organ weights or intestinal histological morphology. Conclusion: The addition of pine needles to the diet of broiler chickens can effectively promote their growth performance as well as improve their intestinal flora and serum status without side effects; in particular, the dose of 0.2% of either PNF and PNS is expected to have the capacity to replace growth-promoting antibiotics as diet additives.

In order to investigate the possibility of functional property improvement of meat products, four kinds of pork patties were prepared with water 10% as control, mugwort extract 10%, pine needle extract 10% and fatsia leaf extract 10%, respectively. In case of control moisture content was higher, but crude fat was lower, compared to patties treated with plant extracts. Crude ash content of pine needle extract treatment showed higher level than that of other patties. pH range of patties revealed to 5.92∼5.978. In raw patties Hunter's L-and a-value of control were higher than those of plant extract treatment, and a-value of raw patties showed higher level than that of cooked. Yield, water holding capacity, salt soluble protein extractability and gel strength among patties did not show significant differences. In control patty, fat retention was lower compared to other plant extract treatments, but water soluble protein extractability was higher compared to pine needle. Values such as hardness, springiness, cohesiveness, gumminess and chewiness were not significantly different among the patties. In sensory scores such as aroma, juiciness and palatability, significant differences were not observed among cooked patties, but texture score was higher in the order pine needle, mugwort, fatsia leaf and control.

To evaluate the quality of fine needle aspiration cytology diagnosis on malignant salivary gland neoplasms, cytologic findings were correlated with histologic diagnosis of 56 surgically removed malignant salivary gland tumors. Seven cases (12.5%) were insufficient, 23 cases (41.1%) were diagnosed as malignant, 17 (30.4%) cases were accurately diagnosed by histologic subtype, and 9 cases (16%) were diagnosed as benign. Five out of 9 false negative cases were misdiagnosed as pleomorphic adenomas. Except the cases with insufficient specimen, overall sensitivity was 81.6%, and the sensitivity varied according to the histologic subtype; 91% in salivary duct carcinoma, 100% in carcinoma ex pleomorphic adenoma, 50% in mucoepidermoid carcinoma, 63% in adenoid cystic carcinoma, and 50% in acinic cell carcinoma. The diagnostic accuracy differed among cytopathologists irrespective of periods after acquisition of board of pathologists. These results confirm that salivary gland neoplasm can be easily misdiagnosed in fine needle aspiration cytology and a great caution should be given in diagnosing the benign appearing salivary aspirates to avoid under-diagnosis of malignant neoplasm with low grade cytologic atypia.

Korea has entered the aged society, with those aged over 65 years accounting for 14~20% of its population. Interest in the quality of life, nutrition, and health of the elderly is increasing. Since the energy intake of the elderly is lower than the estimated required amount, nutrient intake ratio of the elderly is related to mastication. Yanggaeng is a high-energy food made from agar, sugar, and red bean paste. Since it has a soft texture, it is highly utilized as a snack for the elderly who have inconvenience in mastication. Pinus koraiensis needle is known to possess antioxidant and antibacterial effects. The purpose of this study was to develop a functional snack added with Pinus koraiensis needle extract powder known to possess anti-inflammatory, anti-cancer, and antibacterial effects for the elderly that would be easy for them to chew. In this study, yanggaeng was manufactured with 0%, 2%, 4%, 6%, or 8% of Pinus koraiensis needle extract powder, white sediment, and agar. In the experiment, moisture contents, color values texture characteristics, antioxidant activities, and sensory preference results were evaluated. Moisture content was the highest in the group added 6% of the extract powder. It was the lowest in the group added 8% of the extract powder, showing a significant (p < 0.001) difference between the two. Hardness, cohesiveness, and springiness of texture characteristics were decreased significantly (p < 0.001) while the adhesiveness and chewiness of texture characteristics were increased significantly (p < 0.001) as the amount of addition increased. Regarding antioxidative activity measurements, levels of polyphenols were the highest (p < 0.001) in the group added with 8% of the extract powder. DPPH and ABTS radical scavenging activities were increased as the amount of addition increased (p < 0.001). Overall sensory preference was the highest for the 2% addition group. It decreased as the amount of addition increased (p < 0.001). Results of this study indicate that Pinus koraiensis needle extract powder with antioxidant and antibacterial effects can be used to manufacture yanggaeng to make functional snacks with improved quality characteristics for the elderly.

Objective: Much has been known that the systematical theory of acupuncture was developed from stone needle as therapeutic tools for orthopedic diseases in ancient times. Stone needle is very old therapeutic method like moxibustion and has been recognized that it was developed since the Stone Age in China so far. In the present study, it was examined for the origination and formation of stone needle based on stone relics of the Stone Age in Korean Peninsular, the medical and geographical literatures. Materials and methods: The facts of stone needle was examined and arranged on the ancient medical or geographical literatures such as The Yellow Emperor's Canon Internal Medicine, Shanhaijing as an ancient geographical book, etc. The clan societies and family related to an origination of stone needle was chased together with their cultural characteristics and origination. The stone relics which have been digged out of historic sites in the North-East Asia were examined for a relevance to stone needle. Results: In The Yellow Emperor's Canon Internal Medicine, it was referred to the stone needle that originated from a fishery zone related to the east coast district in North-East Asia. Through the examination of Shan Hai Jing as an ancient geographical book and its historical reviews, a Go-yi clan society who keep Go's family tree dealt well with the stone needle and jewels including jade in the North-East Asia before the publication periods of The Yellow Emperor's Canon Internal Medicine, and is comprised in the culture of Dong-yi clan society but not the Chinese culture. The obsidian stones, which have been digged out of historical sites in the North-East Asia since the Stone Age, are originated from volcanic areas combined with seashore that seems to be Baekdu mountain district in Korea and Kyushu district in Japan. Furthermore, obsidian stone tools which were found out at Laodung peninsula and the Korean peninsula are archeologically similar to the stone needle with regards to the shape, size and dual-use. In addition, specific obsidian stone tools have been used in orthopedic surgery as well-crafted obsidian blades have a cutting edge up to five times sharper than high-quality steel surgical scalpels. Conclusion: The origin of obsidian stone needle is well corresponded to the explanation about that of the stone needle. It is suggested that the stone needle which influenced in completion of acupuncture and Meridian theory in China seems to be an obsidian stone, and distribution of obsidian stone needle has been closely connected to Dong-yi clan society which are lived in the North-East Asia including Baekdu-mountain district.

Objectives : Quality control of the needle tips and prevention of pollutions are important factor for safe and effective acupuncture treatment. Ear acupuncture needle is made by 3 companies in Korea, and used to treat for obesity or smoking in clinic frequently, but the Korean industrial Standard is proposed most recently. In spite of the importance, there has been little study about that. Moreover, there was no study about ear acupuncture needle. Methods : We investigated the current condition of needle shape and pollution about the tips and body of the ear acupuncture needle under the stereoscopic microscope. Samples are selected 100 pieces from 300 pieces randomly in each company. Results : The substandard needles are classified into four groups and counted 1. Normal condition (55.3%), 2. Scratch on the surface (14.0%), 3. Malformation of tips (19.3%), 4. Pollution of body (4.3%), 5. Multiple Substandard (7.0%). In the case of including type 2 as a standard needle, normal rate of A company was 81% when B was 76%, and C was 51%. Conclusion : The substandard ear acupuncture needles can induce local side effects such as needling pain or itching. Furthermore, it can disturb the proper effect of acupuncture treatment. We hope that this study can help to improvequality of ear acupuncture and reduce substandard rate for safe and effective ear acupuncture treatment.
