  • Purpose: This study analyzed the factors related to adaptation of people who wears progressive lenses glasses for the first time. Methods: 463 presbyopia (Aged 41~78) without any ocular diseases with the progressive lens glasses were prescribed from 2010 to 2011 at B clinic in the Gwangju city. Progressive lenses adaptation were analyzed according to gender, age, distance refractive state, presbyopic addition, progressive lens design, the old glasses, astigmatism type, and anisometropia etc. High, mid and low-adapted groups were categorized as the status of wearing progressive lenses glasses, re-wearing, occasionally wearing and failed to weraing, respectively. Results: Men showed significantly higher adaptation (p=0.02) than women. Presbyopic addition (p=0.05) and progressive lens design (p=0.02) were statistically significant. However, it was found that there was so statistical significance for the factors of age, distance refractive state, the old glasses, astigmatism type, and anisometropia. Conclusions: According to the results of this study, when progressive lenses were prescribed, we should consider for adaptation gender, presbyopic addition, and progressive lens design etc.

  • Wearing a clothes in human living is very rightful and reasonable things. And it's also the necessaries of living. So now, I want look around about origin of clothes from the prehistorical age, how they start and why they need to wear a clothes. As human culture is unknown origin, human clothes origin is also unknown origin, too. So many different people made unlike story about that, and it is very difficult to say correct birth of clothes. It must be reflection by a time, by a place, by a mankind, until this days, the history of human progress is $2,000,000{\sim}3,000,000$ years. And from after the "Old Adam" man understand what is shame and disgrace, so that made them cover of their private parts, also it is a motive of human clothes. Since after pass a long time, the earth has many changes as it were weather, and for take care of human body from cold, people start make clothes and it's a second object of wearing a clothes. And third object of wearing clothes is after opportunity of development human culture, people desire for an aesthetic sence and for full-fill that feeling they start make a beautiful clothes with accessories and it is motive and a purpose of a human start wear a clothes. So I can say, for origin birth of clothes is 1. Protect of human body. 1) be adapted for different weather and different circumstance. 2) take care self from outside injurg. 2. Decorate for aesthetic sence. 1) Theory of Amulets. 2) Theory of symbolism. 3) Theory of Sex attraction. 4) Aesthetic Theory. 5) Theory of chastity. 6) Multi-theory And material for clothes they made from natural wilds like leaves, fur, skin of wood. skin of fishes and feather etc. But after develop of human knowledge people invent fiber, and use a knitted goods and woven stuff also first of all. They start use those kind that they just cover of their private parts as a belt and astring with leaves and a beast skins. But until this days it's taken big development with human knowledge and most important influence of develop was weather. So modern clothes for present days, must care with. physicology, preservation of health, living activity, dressing, morals, and etiquette etc.

  • Background: Management of positional plagiocephaly by wearing a cranial molding helmet has become a matter of growing medical interest. Some research studies reported that starting helmet therapy early (age 5 to 6 months) is important and leads to a significantly better outcome in a shorter treatment time. The aim of the present study was to evaluate the effectiveness of cranial remodeling treatment with wearing helmet for older infants (${\geq}18$ months). Methods: We conducted a retrospective study of 27 infants with positional plagiocephaly without synostosis, who were started from 2008 to 2012. Every child underwent a computerized tomography (CT) before starting helmet therapy to exclude synostosis of the cranial sutures and had CT performed once again after satisfactory completion of therapy. Anthropometric measurements were taken on using spreading calipers in every child. The treatment effect was compared using cranial vault asymmetry (CVA) and the cranial vault asymmetry index (CVAI), which were obtained from diagonal measurements before and after therapy. Results: The discrepancy of CVA and CVAI of all the patients significantly decreased after cranial molding helmet treatment in older infants (${\geq}18$ months) 7.6 mm from 15.6 mm to 8 mm and 4.51% from 9.42% to 4.91%. Six patients had confirmed successful outcome, and all subjects were good compliance patients. The treatment lasted an average of 16.4 months, was well tolerated, and had no complication. Additionally, the rate of the successful treatment (final CVA ${\leq}5mm$) significantly decreased when the wearing time per was shorter. Conclusion: This study showed that treatment by cranial remodeling orthosis was effective if the patient could wear the helmet longer and treatment duration was somewhat longer than in younger patients, well tolerated in older infants and had no morbidity. This therapeutic option is available and indicated in these older infants before other cranial remodeling surgery.

  • Many varieties in folk costumes have inspired fashion designs for a long time. Each country, with a unique style of its own reflects their own traditions, beliefs, customs and morals into their traditional costumes. The traditional methods of creating different ways of drapery methods by using only a rectangular piece of cloth have been passed down from generation to generation and it is still used today. This way of styling has been developed mainly in the Middle East, Asia and Africa and the modifiable ways of creating drapery wearing methods are as follows. The first modifiable styling method is changing the purpose of wearing costumes according to the needs and the wants of the person who wears it. The second method is exposing the knots on the surface of the garments and by doing this, there was no visible difference on the aesthetic formation and it did not alternate for a long time. This means that simple knot shapes have been used to tie edges of rectangular fabrics. The third method is a wrapping type of modifiable styling method, which has been used most commonly in folk costumes because there are lots of ways to wrap a rectangular cloth around the body. The fourth way is the fixed type of modifiable styling method and this method can only be noticed only in the Moroccan Izar using fibulas and belts to alter the shape of the Izar. The fifth method is the composite type of modifiable styling method. This method starts by cutting out cylindrical shapes of fabrics and then wraps or twists it to fit the body. The most significant character of modifiable styling methods in folk costumes is to use rectangular cloths, which varies only in ratio of length, width and sizes. Therefore, this study suggests that rectangular cloths can create enormous amounts of fashion styling which can be easily adapted and created in everyday fashion life.

  • Purpose: This study aimed to investigate the effect of an intensively rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. Methods: In this study, the anonymized electronic medical records of individuals who participated in the intensive rehabilitation program (among those who were admitted to the hospital belonging to the Labor Welfare Corporation) due to an industrial accident from August 2018 to September 2019 were collected. As a result, the records of 12 subjects meeting the screening criteria were analyzed. Results: According to the time of application to the intensive rehabilitation program, the 10 Meter Walk Test (10MWT) (p < 0.01), Berg Balance Scale (BBS) (p < 0.01), Timed Up and Go Test (TUG) (p = 0.01), the L Test of Functional Mobility (L-test) (p < 0.01), Prosthetic Limb Users Survey of Mobility (Plus-M) (p < 0.01), and Houghton Score Question (HSQ) (p < 0.01) values significantly improved with time. Conclusion: This study confirmed the positive effect of an intensive rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. However, this study was limited by the absence of a control group, and, thus, it highlights the need for more extensive research with a large sample.

  • The purpose of this study is to investigate the effect of wearing clothes, Level B, and Level C PPE on normal CPR using mannequins. The paramedics who participated in this experiment were 20 paramedics with more than 5 years of experience in firefighting area C. It was found that chest compressions in the process that hand off time was 11.9 seconds in the uniform wearing group, 11.4 seconds in the level C PPE wearing group, and 13.1 seconds in the SCBA wearing group. In other words, wearing personal protective equipment prevents the movement of paramedics and uses compensatory movements, which may increase the difficulty of efficient first aid. If this situation persists, it may cause fatigue and damage to the body of paramedics. Rescue and paramedics should wear level personal protective equipment in case of emergencies and conduct rescue and CPR training.

  • Disposable contact lenses, which are one type of soft contact lenses, provide convenience in use, but also cause various ocular infectious diseases. Microorganisms that cause eye diseases include Acanthamoeba, bacteria, Fungi, and so on. It is impossible to prevent microorganism contamination completely due to the use of hands as wearing contact lenses. The contamination by various microorganisms leads to infectious keratitis, but it is not well known for the exact microorganisms that affect the disease. For this reason, to identify the microorganisms, two groups that are commonly used for disinfection of lenses were divided: normal saline solution and multiple purpose solution. Using these solutions the degree of microorganism contamination was observed according to the days of 1, 3, 5, 10, and 15. Twenty students by two groups from Ophthalmic Optics department at D college in Daegu Metropolitan city participated in the experiment after their ocular health conditions were checked. During they wore one-day disposable lenses for 1, 3, 5, 10, and 15 days, bacteria were cultured in media. The results, which were Gram stained by selecting the cultured colonies, show as followings: Gram positive cocci 33%, Gram-negative cocci 2%, Gram positive bacilli 34%, and the Gram negative bacilli 31%, respectively. As for the identification of potential pathogens, VITEK system and API kit methods were used. Keratitis caused by bacteria known as Staphylococcus aureus, Pseudomonas aeruginosa were detected as a result of wearing contact lenses. This study examined the distribution of bacteria as wearing one-day disposable contact lenses and pathogenic bacteria according to the duration of wearing them. In conclusion, the importance of hygiene when using contact lenses is suggested.

  • Objectives: The coronavirus pandemic that began in 2019(COVID-19) has been one of the worst pandemics of the 21st century. Masks have been used to prevent COVID-19, but there are currently no standards for the long-term use of masks in the Republic of Korea. This study was conducted to assess the microbiological safety of KF94(Korea Filter 94) disposable face masks according to wearing duration by evaluating the bacterial filtration efficiencies of masks worn by research participants. Methods: A commercially available KF94 mask certified by the Ministry of Food and Drug Safety(MFDS) in the Republic of Korea was selected as the test mask. The research participants(n = 15) wore masks for the durations of one, three, and seven days. Participants also reported several parameters, including wearing time, makeup frequency, and storage. Bacterial filtration efficiencies of the worn masks were measured by a mask bioaerosol filtration tester. Staphylococcus aureus(S. aureus) was used as the test bacteria and quantitatively measured through the cultivation method. Then, bacterial filtration efficiency was calculated using the formula suggested by the MFDS. Results: All worn masks showed over 99.98% of mean bacterial filtration efficiency for S. aureus. There were no significant differences among bacterial filtration efficiencies of face masks according to wearing duration. There was also no significant difference among bacterial filtration efficiencies among participants. There was no correlation between the results of bacterial filtration efficiencies and reported parameters from participants. Conclusions: In the absence of significant external damage to the mask, the bacterial filtration efficiency of the mask can be maintained even after seven days of wearing. This result suggests that KF94 masks certified by the MFDS can be used repeatedly for about a week without loss of bacterial filtration efficiency.

  • We conducted a study to access the effectiveness of glove and washing hands for the prevention of microbial contamination during the dental clinical practice. Microbial numbers at unwashed hands and gloves were $9.938{\time}10^3(CFU)/ml$, those at washed with soap were $9.44{\time}10^3CFU/ml$ And those at washed with a typical liquid soap including disinfectant, Dettol (Reckitt Benckiser, Slough, SL1 3UH, UK) were $6.58{\time}10^2CFU/ml$. In case of unwashed hand and hand washing with soap had similar microbial numbers and in case of hand washing with Dettol showed a rapid decrease of microbial number. Hand washing with Dettol was effective to prevent microbial contamination than hand washing with soap. Also microbial numbers in all case wearing gloves decreased. It showed effectiveness of gloves for prevention of microbial contamination. In addition to microbial numbers showed a tendency to increase from 3 hours on wearing gloves, the change of new gloves after 3 hours on wearing is necessary to minimize the danger of microbial contamination.
