Pulmonary cavity is the result of necrosis of lung parenchyma with evacuation of the necrotic material via the tracheobronchial tree. A communication with the tracheobronchial tree permits air to enter the area of necrosis, so the radiologic result show the a lucent defect. The radiologic characteristics of the wall of a cavity are determined by the reaction of the lung parenchyma to the pathologic process. Therefore, the shadows of the chest films in cavitary lesion were variable in its nature. The author, in 42 cases which have a cavitary lesion in X-ray findings among 172 cases resected lung obtained in P.N.U.H. from 1979 to June, 1985, studied similarities and differences between the pathogenesis of these lesions and the radiologic findings. The author reviewed the 42 cavitary lesions and the following results were obtained. 1. The cavitary lesions were seen in 42 [24.4%] out of 172 cases of resected lung disease. 2. Histopathologically, pulmonary tuberculosis was 47.6% and primary lung cancer was 9.5%. 3. The most common site of the lesion was right upper lobe. 4. The most common size of the cavity was from 3 to 6 cm in diameter. 5. Lobectomy was the most common operated method.

Research on the Hairstyles Created by Razors and Taper Shears The purpose of this research is to analyze formative changes razors and taper shears make on hairstyles. A total of 28 examples were created by utilizing wigs, models, razor and tapers. They include 12 graduation examples (6 wigs and 6 models), 12 layered styles (6 by razor and 6 by taper shears) and 4 combinations (graduation +layer + razor + taper shear). Formative changes in the production process were analyzed. The conclusions drawn from the research are as follows. First, razors give the hair ends a soft and natural texture. Taper shears are able to control the amount and texture of hair at the same time and, therefore, able to reduce the volume of hair by giving it a variety of textures. Second, the analysis of hair cutting techniques according to section, angle, direction, weight and texture found that razors and taper shears produce different cutting techniques and design factors. Third, hair length, line, base and angle are the factors which cause a formative change in hair cut design. When styling a wig versus a real customer, differences in design technique and design were made at the front and side nape. At the same time, differences in hair type and image caused by different face types caused differences in techniques. The research analyzed cut techniques razor and taper shears can make and their differences through examples. This study should contribute basic data to haircut design research.

Haircut tools include scissors, a razor, clippers, and thinning shears. Using these tools, hair depth and volume are adjusted under diverse haircut techniques. This study attempted to investigate quick and easy haircut techniques through three sections called the 'Easy-3 Section' using a razor which enables the adjustment of hair length and volume at the same time. First, the basic razor feathering technique is divided into basic feathering and variation feathering. Because it is applied to hairpieces, there was a difference in the lightness and movement of hair depending on where the feathering started and which part the razor was applied to. Second, in terms of haircut design by the Easy-3 Section, it was created on a wig with a basic haircut design. Therefore, it appears that in basic haircut design, movement was formed in the expression of texture at the end of hair depending on where the feathering began. In variation haircut design, on the contrary, it seems that it is possible to express trendy styles depending on hair movement. Third, in the Easy-3 Section coordination, feminine, active, romantic, and mannish images are applied in three styles: short, medium, and long. Therefore, it is easy to produce changes to dry techniques by image quickly, using a light and pleasant expression. This study summarized razor-based haircut design techniques and produced various designs. By simplifying current complicated haircut stages with the Easy-3 Section haircut design using a razor, it would be possible to complete a haircut fast (in about 10 minutes).In terms of the limitations of the study, the analysis of haircut design is dependent on the researcher's subjective opinions. In the future, therefore, it is necessary to carry out a more objective study on more diverse haircut designs.

연속식활성오니법 , 반연속식활성오니법 , 진탕배양법에 의한 음이온 계면활성제의 생분해도

The biodegradabilities of sodium laurel sulfate(SLS), sodium lauryl ether sulfate(SLES), sodium alpha olefin sulfonate(AOS), and sodium linear alkylbenzene sulfonate(LAS) were determined by shake culture tests, semicontinuous activated sludge(SCAS) test, and continuous activated sludge(CAS) test specified in KS, JIS, ASTM and OECD, respectively. The relative rates of biodegradation, estimated by methylene blue active substance loss, were in the order of SLS> SLES> AOS> LAS. All surfactants were biodegradable, and it can be suggested that these surfactants are easily degraded in sewage treatment plant.

KS, JIS, ASTM 및 OECD의 계면활성제 생분해 공정시험법인 진탕배양법, 반연속식활성오니법, 연속식활성오니법을 이용해 APG의 생분해성을 조사하였다. Foam loss로 측정한 APG의 일차생분해도는 모든 시험법에서 100%인 것으로 나타나, APG는 하수처리장과 표층수의 조건에서 쉽게 분해됨을 확인할 수 있었다. 또한 OECD의 화학물질 생분해 평가법인 closed bottle test법으로 측정한 APG의 최종생분해도는 75% BOD_(28)/COD로, OECD에서 제시한 ready biodegradability limit인 60%를 초과하여, APG는 자연계에서 쉽게 분해되는 readily biodegradable한 물질인 것으로 확인되었다. The biodegradability of alkylpolyglucosides(APGs) was determined by shake culture tests, semicontinuous activated sludge test, and continuous activated sludge test mandated for testing the biodegradability of surfactants in OECD, ASTM, JIS and KS. APGs showed 100% foam loss in all tests. This means that APGs are degraded well not only in sewage treatment plant but in surface water conditions. In closed bottle test for determinating the ultimate biodegradability, APGs exceeded the ready biodegradability limit (60%) of OECD with 75% BOD_(28)/COD. APGs may therefore be considered as readily biodegradable under actual environmental conditions.
