In this research, we delve into the behavioral decision-making processes of decision-makers possessing bounded rationality within a supply chain framework. We focus on three interconnected decision-makers, each with distinct levels of influence. Our behavioral experiments, centered on their trading dynamics, revealed that these decision-makers don’t solely rely on rational choices influenced by their peers’ responses. Rather, they recalibrate their trading strategies, adopting a collaborative approach that advantages their partners. Such adjustments not only optimize their individual gains but also amplify the collective benefits across the entire supply chain.

Trichofolliculoma is a rare skin lesion. It is an adnexal tumor of hair follicles, which was first described by Miescher. Trichofo-lliculoma is a hamartomatous lesion of hair follicle origin, intermediate in diferentiation between a hair follicle nevus and tri-choepithelioma as classified by Kligman and Pinkus. It usually manifests clinically as a small, slowly growing, well-demarcated, flesh-colored papule on head and neck. The diagnosis is dificult clinically and is based mainly on histopatholigic appearance. It is comonly misdiagnosed as sebaceous cyst, nevus, and basal cell carcinoma. Treatment is by simple excision and recurrence is rare. sal vestibule with a review of literature. (Korean J Otolaryngol 2007 ;50 :265-7)

Syphilis, a chronic systemic infection caused by Treponema pallidum, is usually sexually transmitted and characterized by episodes of active disease interrupted by a latent period. After an incubation period of averaging 2-6 weeks, a primary syphilis with a firm, non-tender chancre appears, often associated with regional lymphadenopathy. Secondary syphilis shows localized or diffuse mucocutaneous lesions and generalized non-tender lymphadenopathy. In about onethird of untreated cases, the tertiary stage appears, characterized by progressive destructive mucocutaneous, musculoskeletal or parenchymal lesions, aortitis or symptomatic central nervous system diseases. Without serological testing, the precise diagnosis is very difficult. In fact, it has often been called the great imitator because it was often confused with other disease. We report a very unusual case of luetic lymphadenitis presented as a solitary submandibular mass.

An abnormal course of carotid artery may surprise surgeons during surgery and result in an transient ischemic attack or other ischemic symptoms. We report an unusual case of kinking in the common carotid artery located below the right thyroid lobe, which was found during a total thyroidectomy in a 74-years old patient. We emphasize in this case how important it is to palpate the neck before surgeries such as tracheostomy, thyroid surgery and so on. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:911-3)

Brain herniation into the middle ear cavity is a rare entity that occurs mostly as a complication of otologic surgery. Other causes include a congenital skull base defect, infection, trauma, neoplasm and irradiation. It gives rise to cerebrospinal fluid otorrhea, progressive hearing loss, tinnitus, meningitis and other neurologic symptoms. Such patients tend to be misdiagnosed as having chronic otitis media and are often treated for long periods with inadequate conservative therapy. We report a case of brain herniation into the middle ear following traumatic temporal bone fracture, which was treated surgically via a transmastoid approach.
