  • In my previous paper (2009), I defended a solution of the Sleeping Beauty problem, according to which, on Monday, Sleeping Beauty assigns a lower credence to the coin's landing heads than 1/2. This conclusion was largely favorable to the Thirder view. However, even if my defense of the Thirder view was successful, it left one important question to be unanswered: Where did the Halfers go wrong? Their main argument was simple: Because Sleeping Beauty does not receive new and relevant evidence about how the coin lands, her credence in its landing heads should remain to be the same. But note that, if the Thirder view was right and Sleeping Beauty receives no new and relevant evidence, then this becomes a special case of the so-called old evidence problem (Glymour, 1980). In this paper, I will explain why it is rational for Sleeping Beauty to change her credence despite the lack of new evidence about the coin's landing heads. For this explanation, I will use Garber's well-known solution to the old evidence problem.

  • Some Korean Philosophers has manifested their opinions on Sleeping Beauty problem. For example, Hasuk Song and Namjoong Kim stands for an thirder, while Hanseung Kim for a perspectivistic compatibilist. In order to fill a vacant position, I shall make an argument for halfers in this paper. My presumption is that the probability the question now given to sleeping beauty is the first question among several is greater than thirder's calculated value. Futhermore, I argue that the probability the coin landed heads on condition that the question now given to sleeping beauty is the first question is greater than 1/2.

  • What van Fraassen calls 'Reflection Principle' is claimed to meet several counterexamples, one of which stands out in the form of the Sleeping Beauty problem. Adam Elga argues that what he believes is the correct answer to the Sleeping Beauty problem shows that Reflection is subject to counterexamples. David Lewis proposes a different answer which preserves Reflection intact. Recently, Nick Bostrom presents a hybrid view which is supposed to allow us to keep Reflection. In proposing his hybrid view Bostrom criticizes both Elga and Lewis while taking some 'good' parts from each. He claims that Elga's view is not entirely acceptable because it presupposes the 'Self-Indication Assumption'. I shall claim, however, that Elga could avoid Bostrom's criticisms by introducing Bostrom's notion of agent-part. I believe that several probability-related puzzles including the Sleeping Beauty problem indicate a promising view concerning the way we should regard our future selves' opinions. According to this view, whether one takes the outsider stance or insider stance makes a difference in an important way that one and the same proposition is associated with different degrees of belief by one agent.

  • This study was conducted to analyze the factors affected morbidity for beauty artists of the limited range of motion about cerviacl, shoulder and wrist, from July 15 through August 30, 2000. Questionnaires were distributed to 373 beauty artists working in beauty shops of Taegu city. The factors included general characteristics, working conditions, life style and regular diagnosis of subject. The data collected were analyzed by SPSS program and the results of this study are summarized as follows; By the marital status, 224(86.5%) out of 259 unmarried beauty artists had the complaint of a neck(P〉0.05), and by the status of education, the complaint rate of a shoulder of beauty artists who graduated university(92.9%) is the highest(P〈0.01). In survey of complaint rates of symptom by the sleeping place, 324(86.7) out of 373 subjects had the pain in shoulder(P〈0.01), specially, beauty artists who are sleeping in bed complained the pain in shoulder more the others, in survey of complaint rates of symptom by sleeping pose, there was the significant different in neck(P〈0.01) and shoulder(P〈0.001). In survey of complaint rates of symptom by regular diagnosis, 61(85.9%) out of 71 beauty artists who took regular diagnosis and 263(87.4%) out of 302 beauty artists who didn't take regular diagnosis(P〈0.05). In conclusion, beauty artists who are on their feet for long time by official trait complaint the pain in neck and shoulder mainly. This result occurs from complex action of general characteristics and work condition and so on. In order to promote the health of beauty artists, there are needs for moderate exercise and regular diagnosis.

  • I take the position of the thirders on the sleeping beauty problem like Elga and criticize Lewisian halfers. In particular, I attack Franceschi's recent arguments for the halfers. In addition, I claim that Bostrom's and Kim's hybrid view is not satisfactory, because it is to pre-empt or to take the burden of proof that the problem is the genuine paradox. Consequently, the purpose of this paper is to show that the thirders' argument is more intuitive than others and what the fallacies of the halfer's arguments are.

  • Professor Song criticizes my view on the Sleeping Beauty problem in his recent paper which endorses the thirder solution. I shall argue that his criticism is based upon a strong interpretation on my view and that this interpretation is neither unique nor proper. Critically examining recent discussions on observer-relativity of probability I shall claim that my perspectivistic solution to the Sleeping Beauty problem is still plausible.

  • An academic article is normally cited within a few years of publication, after which interest falls off as the research field moves on. However, an article is sometimes ignored for many years only to attract interest after a long period of dormancy. Such articles are called "Sleeping Beauties." A general characterization of this pattern has recently been defined and is used in this study to identify five Sleeping Beauties that were published by researchers at the University of Waterloo in the 1970s and 1980s. While a handful of studies have examined the occurrence of such Sleeping Beauties in specific fields of research or in a particular journal, none has yet identified these unusual articles in the context of the lasting impact of a university's research. This study is therefore a novel application of the latest technique for identifying Sleeping Beauties. The possibilities for using this unusual citation pattern in raising the profile of a university's research are discussed.

  • Collagen peptide plays a protective role in skin by increasing the activity of antioxidant, acts like an activator of skin regeneration by positive feedback and is used as a potent candidate for cosmetics or functional food. GABA acts at inhibitory synapses in the brain by binding to specific transmembrane receptors of both pre- and postsynaptic neuronal processes in vertebrates, is also involved in the synthesis of melatonin and might exert regulatory effects on sleep and reproductive functions. In this study, we investigated the beneficial effect of a mixture of collagen peptide and GABA (J85091900) on skin and sleep condition in woman experiencing sleep disorder. We found that oral supplement with J85091900 significantly decreased the value of Pittsburgh Sleep Quality Index (PSQI), increased sleeping time by 7%, and also improved skin roughness (Ra, Rz, Rt), periorbital wrinkle (Ra, Rt), and skin capacitance in human. These findings indicate that dual strategy with which skin improvement is accomplished using collagen peptide and sleeping well is acquired using GABA could be the novel solution for sleeping beauty by edible cosmetics to improve skin status.

  • This study aimed to help the college students majoring in beauty to have interests and manage the functional areas of scalp and hair by accurately identifying the condition of scalp and hair and realizing the convergence management habit and subjective symptoms for the condition. The study conducted a survey on 160 beauty major college universities in their 20s living in the Jeonnam area by asking the subjects to directly write the answers. The study found that many subjects had combination type of scalps and hair problems of split ends and thin hair, and recognized that their hair was damaged. They answered that frequent dyeing and perm caused the damage and they were using the shampoo for damaged hair to prevent hair damage. Regarding the observable symptoms on scalp and hair, it was identified that self-perception was higher as the interest in scalp was high, which influenced age and sleeping time.
